Technical features:
1. The chuck is a built-in cylinder, and it is stepped up and released through the air
pressure control mechanism at the spindle rear.
2. The chuck center is half-through-hole form, and the chuck is suitable for processing
long-shaft parts.
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?
