Power chucks<br />

<strong>The</strong> <strong>Advantages</strong><br />

• Positive pull back action throughout<br />

gripping range<br />

• Easy conversion from external to internal<br />

clamping<br />

• Internally lubricated and sealed<br />

Advanced Ball Lok Chuck ABL<br />

<strong>The</strong> <strong>Advantages</strong><br />

• <strong>The</strong> new post style arm with patent pending<br />

"Quick Lok" jaw mount, further reduces the<br />

overall weight of the chuck as well as reduces<br />

the mass of the tooling extending from the<br />

face of the chuck, allowing not only higher<br />

RPM's, but improved chip shed.<br />

• <strong>The</strong> "Quick-Lok" design allows for jaw<br />

changeover in less than 1 minute.<br />

• <strong>The</strong> one piece bearing improves grease<br />

retention and provides for easier in-house<br />

maintenance.<br />

• <strong>The</strong> arm and bearing are available as an<br />

upgrade to your existing UBL design.<br />

Additional advantages to this<br />

technology:<br />

• <strong>The</strong> composite body provides<br />

a dampening effect, which can improve<br />

harmonics in turning operations.<br />

• Easier handling when mounting<br />

Jaw mounting<br />

<strong>The</strong> new "Quick Lok" jaw mount will provide you with no loose screw design, easy jaw changeover<br />

and a reduction in mass.<br />

Gripping technology for your company<br />

With a range of over 3000 standard products and<br />

individual special purpose chucks FORKARDT offers<br />

you high quality solutions for all workholding jobs.<br />

Whether the ingenious F type hand-operated chuck,<br />

indexing chuck systems, or the latest development<br />

like the QLC power chuck, we continue setting standards<br />

and consolidating our position as a technology<br />

leader.<br />

A great many technical innovations on the clamping<br />

sectors can be traced back to FORKARDT designs.<br />

For instance FORKARDT adopted a pioneering role in<br />

the development and application of centrifugal force<br />

compensation and pressure lubrication on power<br />

chucks.<br />

Just like the first indexing chuck that was ready for<br />

series production, power-operated workholding devices<br />

and the first reliable clamping force meters originated<br />

from the workshop of our outstanding designers.<br />

All of our advancements and new developments<br />

pursue the one goal: utilising reliability and precision<br />

for greater productivity at the optimal economic<br />

efficiency!<br />

For instance FORKARDT has been reducing the<br />

weight of its high performance products for years –<br />

with considerable cuts in the energy needs for the<br />

production process.<br />

And also the VC quick change jaw system is an<br />

example of our products’ added economic value, for<br />

considerable rationalisation effects with great work<br />

piece variance and sustainably high repeat accuracy.<br />

We find your problem gripping<br />

Extraordinary fields of application need extraordinary<br />

solutions. Owing to their shape, size, weight, or<br />

other properties many work pieces cannot be optimally<br />

clamped and machined with the standard chucks.<br />

Our engineers are on the lookout for these challenges.<br />

For them there is no work piece, no matter what it is<br />

made of, that cannot be clamped, and this finds repeated<br />

testimony in over 100,000 designed, produced,<br />

and proven special purpose FORKARDT<br />

chucks on almost all production sectors. This enormous<br />

pool of knowledge can also benefit you.<br />

Many of our special purpose solutions become<br />

standard products, for instance the development of a<br />

centrically clamping indexing chuck with hydraulic<br />

centrifugal force compensation for a fittingmaker. This<br />

product has now become established on the sector<br />

as the best product in the field.<br />

By constantly innovating on the various market<br />

segments like medical engineering, the automotive<br />

industries, new energies, etc., we search for solutions<br />

of even greater refinement in our field of activities.<br />

FORKARDT is therefore constantly challenged to defend<br />

its position at the top of innovative workholding<br />

technology.<br />
