SKC slideway coatings are
used for the production of
guideways and sliding surfaces.
Originally developed
to be used for machinetools,
today, they are applied
for industries being
most different from each
other as e. g. construction
of heavy machinery or of
printing machines, they even
found entry in optical
industry.
Apart from the optimal
technical properties, forming-to-size
technique is offering
a great variety of alternatives
for a cost-saving
production of surfaces in
most different designs.

The diagramme of fricitonal characteristics
shows a comparison of the
frictional characteristics of SKC 3 -
GG 25 (grey cast) and SKC 60 - GG
25 to the pairing GG 25 - GG 25.
The advantages of the SKC slideway
coatings are evident from the following
facts, which are brought out by
the graph:
1. The static friction f o is very low, it
is about 1 / 7 of the value of adherent
friction of GG 25 - GG 25 pairings.
Corespondingly, the starting forces
and the amount of elastic prestressings
which the drives generate until
starting, are low.
2. The frictional characteristic of
motion, i. e. the kinetic friction, initially
rises with increasing sliding
speed and will then drop again,
when the hydro-dynamic lubricating
film is built up. The influence of different
slide-pairings as, e. g. SKCcast
/ cast hardened / steel and steel
hardened on the frictional characteristics
can be ignored.
When positioning components, the
increase of the frictional function
avoids the undesired, jerky stressrelief
of the drive elements after the
start, and allows exact feed in microns.
On the reduction of the sliding
speed to a standstill, and the
end of a feed, the frictional function
declines. Thus, a high stress-relief of
the drive elements is achieved, and
an undesired stick-slip, caused by
relief of stresses under the influence
of shocks and of fluctuations of the
cutting force are avoided.
When machine elements are sliding
at low speed - in the range of
boundary conditions - the increase
of the frictional function generate a
damping of the sliding process, thus
avoiding the undesired stick-slip effect.
In contrast to this, the decreasing
frictional function of other pairings
of sliding materials leads to an
instability of the sliding process and
to stick-slip phenomena.
3. The amount of the friction coefficient
is not only dependent on the
pairing. Using an adequate lubricant
is also of importance. Apart from
their good tribological properties,
modern bedway oils also offer an
excellent behaviour of de-emulsification.
If lubricant penetrates into
the guideway gap, the media will
not get mixed; therefore, in normal
case, difficulties can be avoided. Impeccable
lubrication is the only warranty
for the total function of highquality
machines.

These statements are
based on practical
experiences having
been won over decades
and on a great
variety of researches
carried out at technical
universities and by
renowned SKC users.
Slideway Coatings - Characteristics
SKC Slideway Coatings - Characteristics
Anti-stick-slip Anti-stick-slip Anti-stick-slip behaviour behaviour
behaviour
Even under high area loads, SKC
slideway coatings offer a jerk-free
starting and smooth movement. Minimum
feed (in the range of microns)
and a very precise positioning
are achieved by SKC-coated guideways,
if an adequate drive, an adequate
lubricating system and lubricant
are used. This behaviour is obtained
by the most salient of the positive
properties: the static friction f o
is smaller than the kinetic friction f v .
Resistance esistance to to wear
wear
The excellent properties of the SKC
compounds minimize wear of the
slideway coating and the opposing
guide surface. The readiness with
which it embeds foreign bodies offers
an additional and an effective
protection against scoring.
Forming orming exactly exactly exactly to to size size and
and
at at low low cost
cost
SKC slideway coatings harden without
any technically relevant shrinkage,
therefore the accuracy of the
surface to be formed is truly reproduced
on the SKC antifriction coating.
So, in most cases, a subsequent
and costly mechanical machining
is avoided, as the lubrication
grooves can be formed simultaneously.
Dimensional Dimensional stability
stability
In contrast to many other synthetics,
SKC slideway coatings are scarcely
effected by deformation under load,
in particular, under the influence of
heat (see tech. data).
Damping
Damping
The high accuracy of SKC-coated
guideways and the technological
properties of the slideway coating
allow the minimum of guiding tolerance.
The excellent damping behaviour
of slideways, e. g. compared
to roller-type guideways is therefore
remarkably improved. By the increasing
frictional function in the
boundary area, and into the direction
of motion, damping is given.
The dynamic rigidity of the
machines is improved.
Safety Safety and and and reliability
reliability
The excellent properties under
emergency conditions of the SKC
slideway coatings avoid high wear,
even under unfavourable conditions,
such as inadequate lubrication. SKCcoated
guideways do not “seize”.
Excellent Excellent adhesion
adhesion
SKC slideway coatings adhere excellently
on cleaned metallic surfaces,
and also on existing SKC layers.
Correction of damage or of machining
errors on SKC slideway coatings
can be done easily. Even on
components of machines made of
solventless polymerisable resinous
compound or cement-bound concrete,
SKC slideway coatings have
outstanding adhesion characteristics.
Chemical Chemical P PProperties
P roperties
SKC compounds are resistant to
water, sea water, mineral and synthetic
oils, weak acids and caustics,
gasoline and alcohol.
They are not resistant to acetone,
benzene, methanole, phenoles and
cresoles (under permanent load),
and to solvents (under a longer-lasting
influence).
Any particulars as far as chemical resistance
is concerned have to be
seen under a certain reservation, as
parameters like temperature, time
of action and state of hardening of
the compounds are of importance.
If there is any doubt, we recommend
to provide specific storing
tests.
In cases of long-term influence under
watery solvents, as well as by
depositing of oxydes, fission and
metabolic products (especially from
water-mixable coolants/lubricants)
dimensional variations of some microns
might occur.
Upon request, we are well prepared
to send you detailed and relevant
information.

Guidelines for Application
Slideway Coatings
Preparation reparation
Roughening of the surface to be
coated
To improve adhesion, the guide surface
to be coated has to be roughened.
The peak-to-valley height
should be about 0.5 mm
(R t =500 µm). Roughening can be
provided by rough-planing, roughmilling,
by cutter or by bore hole,
i.e. by turning a thread. Sandblasting,
using hard and sharp grains
(blasting medium: a high-furnace
slag G 77, grain 0.6-1.2 mm) offers
an especially good adhesion surface.
In case of all these processes, care
has to be taken, that the surface will
not be compressed, but will be
cracked.
Example for roughening of the surface to be
coated by planing (lh.) and milling (rh.)
Cleaning of the surface to be coated
The components to be coated have
to be cleaned thoroughly. For precleaning
various cleansing agents can
be used.
We are at your service to provide
you with information on a suitable
cleansing agent.
The surfaces to be coated have to
be free from oil, grease, dust, rust,
scale and protective paint. In case of
a mineral cast, it is necessary to remove
the layer of separating wax or
treatments. For the final cleaning before
coating, preferably acetone
should be used. Care has to be taken
when compressed air is used
for dry-blowing of the adhesion surfaces,
because it often contains oil
which might affect adhesion.
Counter guideway and forming-tosize
surface
SKC coatings can be formed to size
from all kinds of counter guideways,
from devices (masters), from the
counter surface, or - for instance -
from gauge plates or templates.
When forming, the roughness of the
counter guideway should not exceed
R a = 2.5 µm. The counter
surfaces can be ground, fine-milled,
broad-smoothened planed or fineturned.
Releasing compounds
The surfaces from which formingto-size
is provided, are to be treated
with a releasing compound. Depending
on the specific case, various
releasing compounds are available.
Each to type, they are applied with a
cleaning rag or a brush or they are
sprayed on. After application and for
a short time, the releasing compound
layer is left to dry and then
carefully polished with a soft cloth.
Please, see chapter ‘Accessories’ for
a description of the various releasing
compounds.
Before coating, all areas on which
compound might escape during the
forming process and where it has to
be removed after hardening, are
also to be treated with a releasing
compound.
About 1 kg of releasing compound
is required for the application of 10
kg of slideway coating.
Formable oil grooves
The forming-to-size technique allows
a simultaneous moulding of the
oil grooves. The pre-fabricated
shapes of the oil grooves are sprayed
with an adhesive spray and adhered
on the forming surface. It is im-
Slideway Coatings Guidelines for Application
portant to spray only a thin layer of
the adhesive and to let it ventilate
after spraying. For precise information,
please, see the instructions of
use on the adhesive spray. The
shapes of the oil grooves have to be
pressed on tightly and then to be
treated with a releasing compound.
After hardening of the compound
the shapes of the oil grooves can be
removed from the compound. The
oil groove itself can be lifted at its
end by means of a pointed tooling
and be withdrawn by hand.
All application techniques allow a
forming-to-size of the oil grooves.
For shapes and dimensions, please,
see chapter ‘Accessories’.
Calculation of quantity
For application by spatula, the volume
of the coating groove - in cm 3 -
is multiplied by factor F m . This gives
the required quantity of the compound
in grammes. Factor F m allows
for the specific weight as well as a
safety margin and depends on the
compound to be used and the application.
The applicable value can
be seen from the technical data.
Example of calculation for injection method
material: SKC 60 (F m =2):

Removal of the coated component
After hardening, the component can
be lifted off. In case of very big
workpieces, additional devices
should be used to relieve the crane,
as e.g. pressure screws or a winch.
Before lifting off, and if possible, the
component should be loosened in
the direction of motion of the guideway.

Retouching work
At the front, the edges of squeezed
out material have to be removed
using either a portable grinding machine
or a coarse linen cloth. Lateral
edges of squeezed out material are
to be traced and to be cut off with a
flat chisel.
Flaws, pits or chipped parts
! of the coating can easily be
repaired. In this area, the
slideway coating will be roughened,
decreased and the flaw to be filled
in with SKC coating. For quick repairs,
SKC 63 R is available. Flaws
having been repaired with this compound
can be treated already after
3-4 hours. If necessary, all the SKC
slideway coatings can be machined
mechanically (see also the table with
the empirical values).
For all the mechanical processes,
care has to be taken that no heating
of the surface of the coating will occur.
Bore holes for lubricants are to be
opened by boring from the coating
side to prevent an escape of the
coating.
Application Application by by spatula
spatula
Positioning
The workpiece to be coated is positioned
at its moulding surface on
setting screws, feelers, stops, and by
means of clock gauges or water levels
so that is dimensionally aligned
to the surfaces of reference. As the
workpiece has to be removed in order
to apply the SKC slideway coating,
the positioning points have to
be marked.
Mixing
SKC slideway coatings are available
in various ready-for-use packs containing
epoxy resin and hardener
precisely proportioned to each
other in weight. So, an additional
weighing is not required and should
be avoided. For mixing, the epoxyresin
compound has to be loosened
with a spatula from the tin wall and
the tin base, the hardener is to be
poured in and to be mixed in by
hand. Subsequently, at about 400
rpm, the two components are to be
mixed well with the SKC stirrer

which has to be chucked in a drillor
in an upright drilling machine. A
stirring time of 3 minutes has to be
observed. Take care that the stirrer
will not grind at the tin base, as
otherwise, the compound will heat
up.
After mixing, the SKC compounds
applicable by spatula have to be taken
out of the tin immediately and
to be spread out on a sheet (see ill.
below). By spreading out the compound,
a certain part of the reaction
heat is released, thus increasing the
pot life; any air bubbles stirred in are
cracked. If the material remains in
the tin, a heat accumulation is created,
which may lead to a short-term
hardening. For a quantity of 0.5 kgs
of SKC compound applicable by
spatula, a sheet measuring about
500 x 500 mm should be used.
Application time and temperature
The application time is depending
on the material to be used. The
right values are shown on the table
‘Technical Data’. SKC coatings require
an ambient temperature of at
least 18 °C. For the coating process,
the workpieces, too, must have this
temperature; if necessary, they are
to be heated by radiator.
Application of the coating
By means of a spatula, the material
is removed from the sheet and applied
in several thin layers, where the
first layer has to be pressed carefully
into the roughening. At the end, the
material has to be applied somewhat
roof-shaped, so that the compound
is displaced from the in- to
the outside without any air poc-kets
when placed against the countersurface.

Forming-to-size of the mating
component
The workpiece is positioned on the
moulding point and lowered to the
aligning points (setting screws etc.)
which had been marked before. Excess
material is squeezed off. Any
corrections within the range of
some 1/100 mm can still be carried
out into direction of the coating. In
no case shall the mating component
be lifted, as this would draw in air
pockets. Light workpieces are in addition
to be loaded with a weight or
to be clamped with retainer gibs or
screw clamps. When the aligning
points are reached, the workpiece is
unloaded or respectively unclamped.
Injection Injection Injection method
method
Preparation
For an application by injection, the
layer thickness depends on the material
to be used and should be
about 2 mm (please see technical
data for the minimum layer thicknesses).
Depending on the press
system which is used on workpieces
having a coating length of up to
about 1000 mm, the injection bore
has to be provided in the centre,
thus enabling a uniform distribution
of the compound into both directions
of the coating gap. In case of
longer pieces, several injection bores
are required being at a distance
of about 500 mm to each other. For
a vertically arranged coating gap, the
injection bore has to be arranged as
low down as possible.
Sealing
Depending on the possibilities of
design or of the techniques of production,
sealing is carried out by
metallic edges or by foam-rubber
strips.
Metallic edges are used as a direct
support, and should be pre-machined
exactly, according to the dimensional
requirements. Before
coating, adhesive-tape strips (e.g.
linen-reinforced adhesive tape
0.3 mm thick) can be adhered on
those edges free. A subsequent undercutting
of the compound is not
required.
When sealing with foam rubber, an
optimal sealing effect is obtained
when the profiles are compressed
to about 50% of their original thickness.
Positioning
The workpiece, cleaned and prepared
for coating is placed on the
moulding surface, which has been
treated with the releasing compound,
aligned by means of setting
screws or similar devices, and fixed.
During injection, the aligned component
has to be kept in position,
by means of retainer gibs, screwclamps,
etc. , so that a displacement
caused by the injection pressure, is
avoided. In a range of a few 1/100
mm a re-adjustment into direction
of the coating can be done after injection.
Mixing
SKC slideway coatings are available
in various ready-for-use packs containing
epoxy resin and hardener
precisely proportioned to each
other in weight. Therefore these
ready-for-use packs should be used
completely.
For mixing, the epoxy-resin compound
has to be loosened with a
spatula from the tin wall and the tin
base. In case of the low-viscous
compounds SKC 62 and SKC 90,
the fillers deposit after a certain
stock time and - before adding the
hardener - they have to be stirred
up thoroughly. For this purpose, the
residue has to be loosened from the
tin base and the resin compound
stirred thoroughly until the compound
is clod-free. Before further
use, the resin compound has to
cool down to ambient temperature.
Then, the hardener is added and
carefully poured in and - for 1 minute
- mixed by hand intensively with
the resin. Final mixing at about 400
rpm with the SKC stirrer which has
to be chucked in a drill- or in an upright
drilling machine. A stirring time
of 3 minutes has to be observed. An
insufficient mixing of the two components
might cause the risk of soft
spots.
Slideway Coatings Guidelines for Application
Systems of presses
(see also ‘Accessories’)
The coating has to be poured in a
thin stream onto the wall of the
cartridge which should be held in an
inclined position. Press the piston
into the filled cartridge and ventilate.
For ventilation, the cartridge has either
to be deformed slightly by depressing
the piston or providing
ventilation by adding a thin wire during
inserting the piston. Afterwards,
the wire has to be removed.
Only for cartridges SK500, KK1000:
The tip of the thread nipple is to be
cut off and the nozzle to be reduced
to the diameter of injection bore
(see chart on right side). Then, the
diaphragm inside of the cartridge is
pierced from the front through the
nipple. Attach nozzle as required.
Insert the cartridge into the press
and close the press with the sealing
cap. Hold the press vertically upwards
and ventilate it until a small
quantity of compound escapes. According
to the press system, the
cartridge nozzle is to be pressed or
screwed into the the injection bore
provided. Press the coating for joint
faces slowly and continuously into
the gap, until it escapes through the
ventilation bore at the farthest
points.
Coating of long workpieces with several
injection bores
The coating process is started from
the central injection bore. Pressing
in has to be continued until the
compound escapes from the adjacent
injection bores. Then, remove
the press and seal the bore with a
thread plug. Now, sequence of coating
is continued from the bores
where the compound has escaped.
The process is repeated, until the
complete guideway is filled. Coating
of longer workpieces should be carried
out simultaneously with two
presses.

Pouring ouring ouring method
method
The preparations are corresponding
to those of the injection method. As
filling of the compound into the coating
gap is done almost without any
pressure, pourable slideway coatings
can be poured in directly off
the can. A thin jet makes air pockets
crack and escape.
In other cases, a filling of the gap is
functionally made via a hose (PVC
transparent, Øinside 12 x 2 mm).
This hose is plugged onto a short
piece of a pipe having an outside
diameter of 12 mm. The cartridge
together with the nozzle is then inserted
into the free end of the hose;
the cartridge itself will now be filled
directly off the can. When the compound
escapes at the control bores,
the latter will be closed. As a material
reservoir, the filling hose remains
connected until separation. In case
of horizontal gaps, the filling bore is
to be arranged centrally and for vertical
gaps at the lower end.

scores.
The coatings SKC 63 R and
SKC 400 R, applicable by spatula,
have been developed for the repair
of blow-holes, for instance of inclusions,
open spaces or scores.
Before repairing worn-out guideways,
the scores have to be milled or ground
down to the exit (‘zero transition’)
about 1 mm deep.
Using, for instance, a portable drilling
machine with a grinding point, inclusions
have to be ground or milled so,
that the created blow-hole can be
filled easily and is free from contaminations.
In order to reduce re-machining and
to press the coating into the scores or
into the inclusions, a guide-bar, ground
and pre-treated with a releasing compound
should be placed or chucked
onto the coated area.
Alternatively, or on uneven surfaces,
the repaired areas can me masked off
with a smooth adhesive tape, after
they had been filled out with the
repair compound.
The repair compound combines itself
homogeneously with all the SKC
coatings and adheres excellently on
all cleaned and roughened surfaces
(e. g. metal, mineral casting etc.).
The hardening time does strongly
depend on the temperature conditions.
At room temperatures of 20 °C,
the repaired surfaces can be rescraped
2 hours after the compound
has been applied.

with V-ledge ‘c’ and two retainer
gibs for cover strips ‘d’ (ill.1).
2) Pre-machining of the surfaces to
be coated is provided by rough-planing
or rough-milling to obtain the
surface shown by ill. 2. By roughmilling,
a similar surface shall analogously
be created by circular scores.
The theoretical layer thickness over
the score tips shall be at least 1 mm.
All counter surfaces used for the forming-to-size,
which have to be finished
and to be optimally aligned, are
treated with a separator and smoothened
with a soft rag.
It is also recommendable to treat
those areas of the free surfaces with
the separator on which - during
moulding - the compound may escape,
and wherever possible, to
protect them with an adhesive tape.
The preparations of a coating process
do also include determination
of a measuring and aligning method
to produce the layer thickness and
the necessary position of the bottom

of the slide and to the spindle axis.
Suitable devices and gauges have to
be at immediate disposal, as during
the moulding process, the time
available to align the bottom slide is
limited.
3) After applying by spatula the
slideway coating onto the surfaces a

Guidelines for Application
Coatings for Joint Faces
Preparation reparation
Before coating, the surfaces should
be cleaned carefully from grease and
contaminations. Films of oxide and
mill scale have to be removed.
If a separation of the components is
envisaged, one surface has to be
roughened, e.g. by milling or sandblasting.
The counter surface has to
be finish-machined and to be treated
with an releasing compound.
The dimensional accuracy is not affected,
if the thin film of the releasing
compound is re-polished with a
soft cloth. In addition, a fixing in position
of the two components to
each other is required e.g. by cylindrical
or tapered pins, so that the
original geometry of the forming position
is obtained when the components
are separated and reassembled.
The injection bore hole - depending
on the system of cartridge press
used - has to be arranged in the
centre of coating surface. To obtain
a better distribution of the compound,
the exit bore (core hole)
must have a wide counter-sink. For
ventilation and control, bores or
notches have to be provided at
points farthest from the injection
hole. When injecting the compound
through an angular bore, pocket holes
should be avoided to prevent
any air pockets!
Aligning Aligning
Aligning
The required accuracy of the machine
parts to each other is obtained
by aligning with setting screws (tension
and clamping bolts) or with
other auxiliary elements (setting wedges).
If injection or pouring technique
is applied, the surfaces to be
coated have to be sealed, e.g. by
foam rubber, adhesive tape, sealing
mastic etc.
Mixing
Mixing
The fillers could be subject of separation
depending on the storage
Coatings for Joint Faces Guidelines for application
time. Therefore they must be stirred
thoroughly before adding the
hardener. The coating residue has
to be removed from the tin bottom
and the resin compound to be mixed
- clod-free - with the stirrer. Before
further application, the resin
components have to cool down to
ambient temperature.
Following this the hardener is added,
carefully poured in and - for
one minute - intensively mixed by
hand into the resin compound. By
means of a stirrer, clamped in a drill
or in an upright-drilling machine, the
two components are ready mixed at
about 400 rpm. Here, a stirring
time of two minutes has to be observed.
Insufficient mixing of the two
components will prevent proper
hardening. In the ready-to-use packings
the mixing ratio of resin and
hardener is exactly adapted to each
other, therefore these ready-to-use
packings should be used completely.
Spatula Spatula method
method
With a metallic spatula, the compound
is taken out from the tin and
to be spread out on a sheet metal.
From there the compound is taken
with a spatula and applied in several
thin layers, where the first layer will
carefully be pressed into the roughening.
Finally, the compound has to
be applied somewhat roof-shaped,
thus allowing its distribution on the
counter-surface without any air holes
during moulding.
Injection Injection method
method
The coating for joint faces has to be
poured in a thin stream onto the
wall of the cartridge which should
be held in inclined position. Press
the piston into the filled cartridge
and ventilate. For ventilation, the
cartridge has either to be deformed
slightly by depressing the piston or
by providing ventilation by adding a
thin wire during inserting the piston.
Afterwards, the wire has to be re-
moved again.
Only for cartridge SK500, KK1000:
The tip of the thread nipple is to be
cut off and the nozzle to be reduced
to the diameter of of injection bore
(see chart on left side). Then, the
diaphragm inside of the cartridge is
pushed from front through the
nozzle.
Insert the cartridge into the press
and close the press with the sealing
cap. Hold the press vertically upwards
and ventilate it until a small
quantity of compound escapes. According
to the press system, the
cartridge nozzle is to be pressed or
screwed into the the injection bore
provided. Press the coating for joint
faces slowly and continuously into
the gap, until it escapes through the
ventilation bore at the farthest
points. In case of horizontal gaps,
the injection bore is to be arranged
centrally and for vertical gaps at the
lower end.
Pouring ouring method
method
Into wide (> 4mm) and easily accessible
gaps, pourable componds
can be poured in directly from the
can. A thin stream enables air bubbles
to tear off and to escape. In
other cases, a filling of the gap is
functionally made via a hose (PVC
transparent, Øinside 12 x 2 mm).
This hose is plugged onto a short
piece of a pipe having an outside
diameter of 12 mm. The cartridge
together with the nozzle is then inserted
into the free end of the hose;
the cartridge itself will now be filled
directly off the can. When the compound
escapes at the control bores,
the latter will be closed. As a material
reservoir, the filling hose remains
connected until separation. In case
of horizontal gaps, the filling bore is
to be arranged centrally and for vertical
gaps at the lower end.

The bearing seats of main spindles
running in antifriction bearings are
exposed to high demands of accuracy.
Any deviations of dimensions
and of design are transported to the
thin-wall bearing rings: alignment errors
may affect the gravitational conditions
inside of the bearings. The
consequences - among others -
could be insufficient running accuracy
and rigidity of the spindle, as well
as higher friction and faster wear of
the bearings.
Often, the available machines are
not capable of achieving the necessary
accuracy of the bearing seats
inside the spindle housing. The use
of bearing bushes, which permit
precision machining without any
problems, is solving this problem.
These bushes have to be mounted
inside the spindle housing in positional
accuracy, free from any deformation
and with a high rigidity.
Nowadays, liquid injected hard-set
plastics can be used. The diameter
of bores of the spindle housing are
widened, so that vis-à-vis the bearing
bushes annular gaps are produced.
Plastic is then injected into these
gaps, and after hard-setting, this
plastic provides a non-slip connection
between the spindle housing
and the bearings bushes. Previously

Bearing bushes of turning-lathe
main spindle

housing
the bearing bushes, together with
the bearings have been mounted on
the spindle, and by means of devices,
this unit aligned and fixed to
the reference surfaces of the spindle
housing. A careful sealing of annular
gap avoids plastic from escaping and
from contaminating the bearing.
Compared to bearing bushes which
would be mounted directly into the
bores of the spindle housing, this
procedure offers the following advantages:
� � �
high accuracy of positioning the
bearing bushes relative to each
other which can be achieved
no transition of geometrical error
of the bores of the spindle housing
to the bearing bushes
improved cold flow from the
bearings into the spindle housing
reduced costs to provide the
spindle housing bores and the
outer surfaces of the cylinders of
the bearing bushes.
In addition, it appears to be possible
- if the plastic layers are suitably dimensioned
and probably in connection
with a cooling of the bearings
- to decrease the heat flow inside
the spindle housing and to reduce
deformation by heat.
The influence of the plastic layers on
the behaviour of the main spindle
and its bearing has been investigated.
Main point of the first investigation
was to find out the static and
dynamic rigidity, the thermical behaviour
of the bearings and the deformation
by heat of the spindle housing.
The plastics used for this purpose
were filled epoxy resins from various
manufacturers. In comparison
with other plastic, these resins are
reaching a very high rigidity, offering
elasticity modula of more than
10.000 N/mm 2 and they widely
comply with quite a few demands,
such as:
� � � � �
liquid processibility
low swelling and shrinkage during
hard-setting
good adhesion on metallic surfaces
good resistance against water,
oils and greases
no hygienic or environmental
risks in hard-set condition
Among other applications, and suitably
modified, is their use for making
frameworks (polymer concrete)
and guideways (antifriction coating).
The researches have shown, that
nowadays, plastic materials are
available with which bearing bushes
can be embedded into the bores of
spindle housings without a considerable
change in the behaviour of
the spindle bearing system.
Consequently the engineering advantages
of this process can be exploited
for a wide range of spindle
bearings.
Moreover, it leads to functional advantages,
too. The dimensional and
designing accuracy of the bearing
seats can be better, as the bearing
bushes allow a better accessibility
for fine machining than a spindle
housing. Vis-à-vis adapted bearing
bushes, the deformations of the end
of the bearing bushes are smaller
and a higher rigidity can be expected.
Misalignment of the bearing
seats can mostly be avoided, as by
the spindle and by the spindle bearings
the bushes can be accurately
centred. The provisions improve
the rolling conditions inside the bearings
and have a favourable effect on
friction and wear. Besides, with regard
to the thermical behaviour of
the bearing and of the spindle hou-
27

Coatings for Joint Faces Example of Application
28
sing, opportunities of improvement
seem to be given, if the suitable plastic
material and the correct dimensioning
are used.
The application of hard-set plastic
materials, demonstrated here with
the example of the bearing bushes,
could also lead to advantages when
applied to other elements of a machine
tool. It allows to avoid expensive
machining of high-precision
joint faces and to reduce heat flow
in precision-determined components.

The releasing compound SKC 15 is
a dispersion of waxes in a mixture of
solvents.
This releasing compound can be
used for most of the cases of application.
Applied with a rag or a brush
and re-polished with a soft cloth after
drying, this releasing compound
is generating a highly-effective releasing
film dimensionally not determinable.

The silicon releasing compound
SKC 14 is used for all forming-tosize
jobs. In particular, for the moulding
of arbors or components with
an overall coating, the lubrication
effect of the releasing film allows a
simple removal of the coated component.
However, care has to be
taken in the proximity of components
which have be to lacquered later
on, as removal of the silicon releasing
compound is difficult and residues
strongly affect the ability of
lacquering.

The release wax SKC 13 W is used
to obtain releasing films thicker than
those which can be obtained with
other releasing compounds of the
series SKC 15 and SKC 14. As SKC
15, it is applied with a cloth. The release
wax enables closing of even
small pores in the surface to be formed.
For high-precision formings to size,
however, this release wax cannot be
recommended. But it can be used
for forming jobs from very rough
counter surfaces.

Application
Application
The counter guideways and the surfaces
to be formed are to be cleaned
carefully. With a rag or a brush,
the releasing compound is applied
or sprayed on (SKC 12 TRS and
SKC 14 TRS). Following, the surfaces
are re-polished with a soft
cloth. Before coating, all areas where
compound may escape during
the moulding process and has to be
removed after hardening, have also
to be treated with a releasing compound.
When using the release sprays, absolute
care has to be taken that -
when applying the releasing compound
- all the components to be
coated are carefully covered, thus
being protected from spraying mist.
Determination of the quantity
(guide value):
For the application of about 10 kgs
of SKC-compound about 1 kg of the
releasing compound is required.
Important
If the releasing compounds are repeatedly
applied on the same component
(forming-to-size templates
or masters), they all tend to build up
hard layers.
These layers can be removed by
applying suitable solvents or siliconremoving
compounds.

Application is similar to that of the
pouring technique (see guidelines of

the injection bore a short tube of an
outer diam. of 12mm has to be
screwed or to be adhered, on

is to be inserted and clamped by
means of the setting screw. When
coating, care has to be taken that
sufficient compound is available in
the cartridge, thus preventing air

Application
1. Cut the grid of lubrication
grooves to the size required (with a
pair of scissors or a knife). For this,
note the following:
All the channels should be open at
the edge of the guide. The distance
to the edge of the guide path should
be at least 10 mm.
2. Applying an adhesive spray on
the surface of the counter guideway
which has been marked before and
been treated with a releasing compound,
following the guidelines of
application, the grid of the lubrication
grooves has to be glued on and
to be pressed on tightly with a rubber-
or a foam plastic roller.
3. The grid has already been pretreated
with SKC releasing compound.
Polish the layer of releasing
agent with a short bristle brush.
4. During scraping, the
grids remain in the layer, as !
the layer - not interrupted
by grooves - can be scraped without
any problem.
5. After moulding lift the grid with a
pointed tool and remove carefully.

Developed especially for vertical
guideways, this layout of lubrication
grooves offers some advantages:
- the oil consumption required to
generate a lubrication film is by 60
% less
- capillary forces retain the oil within
the grooves at the vertical
guideways
- close cross sections provide an
immediate distribution of the oil
on the sliding surface, whilst -
with conventional systems - have
to be filled first
- the position of the injection bore
has not to be determined exactly
- grids are also available for the vertical
faces of horizontal cross slides
(shape MH)
- In order to have a sufficient quantity
of lubricant available at high
speeds to generate a hydrostatic
lubricating film, grids should be
designed with additional feeder
grooves transverse to the sliding
direction. The grooves can be added
later by hand or included in
the moulding process. Our production
programme does include
numerous grids with additional
transverse grooves (see below on
L.H. side).

Principal Instructions on
Labour Hygienics
Good conditions of labour hygienics
are the absolute pre-requisite for a
safe and riskless use of plastic
materials.
Transport and storing
To prevent impurities, resins and
hardeners have to be transported
and stored in well-closed containers.
Any spilled material has to be
taken up, whereby any contact with
human skin has to be avoided.
Working place
The working place and its environment
have to be kept clean. When
mixing the components, best cleanness
has to be observed.
One-way utensils
Wherever possible, we recommend
to use of one-way utensiles (e.g.
plastic cartridges). After use, these
utensils are to be thrown away into
the plastic bag of dust bin locked
with a cover.
Cleaning of devices
Devices polluted by unhardened
mixtures of resins and hardeners
can be cleaned easily with suitable
solvants. For cleaning, protective
gloves, a rubber apron and protective
spectacles should be worn.
Ventilation/Exhaustion
The warehouses and working
rooms should be provided with an
efficient ventilation system. On sources
of vapours and dust, local exhaustion
devices are also necessary.
Skin protection
Any contact of the skin with working
materials has to be excluded by
wearing protective gloves (possibly
gauntlet gloves). Besides, we recommend
to use a suitable skinprotection
cream.
Any splashes which reached the skin
are to be dabbed with a paper.
Then, this part of the skin should be
washed with warm water and soap.
Do never use any solvants to purify
human skin, because they destroy
the natural skin protection. After cleaning,
the skin should be treated
with a nutrient cream.
Training of the staff
The appropriate handling of chemical
products can be warrantied only,
if the involved personnel has been
informed well and sufficiently on the
risks and on all details of the safety
measures.
Experience has shown that observance
of the precautionary measures
has to be controlled
continuously.
The purpose of these instructions is to
draw attention to probable risks when
using our plastic materials. We are
well aware, that it is impossible to
compile a catalogue comprising are
imaginable sources of risks or dangers
including the safety measures resulting
from those risks or dangers. It is
quite possible, that individual products
require additional information
or instructions. In this context we refer
to the safety data sheets which
are available for our products and we
also refer to the instructions given on
the products themselves.
