Technical features:
1. Patent product, vertical type with baseboard.
2. Super thin body, easy retrofit.
3. Built -in cylinder structure, convenient for installation.
4. Accuracy, within 0.03mm.
5. Pneumatic operation Standard.
6. This chuck is applicable for machining center, driller and miller.
7. 2 jaw and 4 jaware available.
8. Rigid and short construction makes the stationary 3 jaw chucks ideal for
operating in machining centers

There are three questions to answer to aid the correct choice of power chuck:
1. Type and model of CNC lathe.
2. Length of workpiece?
3. Outer diameter of workpiece?
4. Processing requirement?
