Description

APPLICATION
For clamping tasks for internal and external clamping where the axial run-out errors of the workpiece have to be minimized.

TYPE
Power chuck with draw-down and ball lock principle available with cylindrical center mount or short taper mount.

CUSTOMER BENEFITS
Maximum plane-parallelism thanks to active draw-down by the jaws
Maximum productivity thanks to long maintenance intervals - hermetically sealed against dirt and cooling water
Consistent workpiece quality thanks to constant clamping force due to oil filling
Suitable for high speeds (speed-dependent centrifugal influences are minimized by similar mass distribution to the right and left of the ball lock)

TECHNICAL FEATURES
Ball lock principle with wedge hook system
With fixed jaws (pendulum jaws on request)
Note: Alternatively with swinging ball lock for clamping rough, easily deformable workpieces at six clamping points on reques
