High Precision Sliding Jaw Pneumatic Chucks
 
PML-PAL high precision air-clamping systems not only quality, highly flexible auxiliary clamping units designed to solve gripping or clamping problems in turn-key machines. They can also be applied for all different kinds of metal working machines as ordinary attachments.

The standard product range covers all diameters between 25mm - 300 mm with a standard clamping jaw stroke from 0.7mm - 3mm with either 2, 3 or 4 jaws. The chucks can also be designed according to specific component or application requirements or meet specific customer demands.

We can also design and manufacture chucks / clamping systems for the clamping of non-standard and complicated parts for finishing and fine finishing operations.
