4 JAWS COMBINATION CHUCK

This chuck is equipped with four jaws with a adjustment mechanism.
Centering is carried out after low-pressure grasping by yse of two-stage hydraulic pressure, and the pressure is increased to strongly grasp a workpiece.
As the workpiece is grasped with hydraulic pressure, non-rounded workpiece can be reliably grasped.

＜FEATURE＞
●Grasping by hydraulic pressure eliminates variations in grasping power.
●Rough centering can be carried out with a hydraulic clamping function before alignment by use of a fine adjustment screw.
●Even non-rounded workpiece can be reliably hydraulic clamped.
●Unclamping of workpiece can be carried out at on operation.
