Best Reasons for Choosing a TMC / LINOS Product
LINOS and TMC are your ideal partners
for vibration isolation solutions. For over
30 years, TMC has specialized in providing
precision working surfaces and
vibration isolation systems for precision
measurement laboratories and industry.
Quality Feature 1
The sidewalls in all Table Tops and
Breadboards from LINOS and TMC
are made of 2 mm thick, damped,
cold-rolled steel profile. The inexpensive
sidewalls made of chipboard
in a competitor product
can absorb moisture, which
causes the material to swell. Furthermore,
they do not ensure unimpeded
heat transfer.

Quality Feature 3
Competitive construction
To provide optimal performance, both
precision “tops” and their supporting
isolators must be designed to address the
central issue: control of environmental
noise.
Quality Feature 2
Table Tops in CleanTop®II design feature top and bottom plates bonded
directly to the steel honeycomb core. When a plastic insert is used
to seal the tapped holes, the insert and its additional adhesive joints
weaken the overall structure considerably. Furthermore the plastic layer,
like the wood sidewalls, obstructs the transfer of heat through the
plate. If one side is heated, massive warping can result (bimetal effect).
The patented CleanTop®II design with its slender, cylindrical protective
caps enables a more closely-meshed honeycomb core structure than a
conical cap form permits. The honeycomb cells average approximately
3 cm 2 , making them 50 % smaller than those in the competitor product.
This ensures higher rigidity and heavier dead weight.

choosing the optimum solution for your
vibration isolation task.
Competitive construction
Quality Feature 4
The honeycomb core is bonded
to the top and bottom plates
with epoxy resin and the Table
Top is pressed between two highprecision,
lapped granite slabs
until the adhesive has set.
The CleanTop®II design also guarantees a maximum thread engagement
depth of 25 mm. Even a slight misalignment of the plastic insert
reduces the thread engagement depth significantly, and in extreme
cases can damage the sidewall.

Competitive construction
This procedure precludes the
need for post-processing steps
such as polishing, and guarantees
an unparalleled planarity of
better than ± 0.13 over the entire
table surface. The competition
cannot guarantee this planarity
over a surface greater than
600 mm 2 .
