1. The chuck is a built-in cylinder with large clamping force, good sealing, high
precision, safety and reliability, nice economical and pracitical applicability
and long serve life.
2. The chuck can be used for precessing square parts and other special-shaped parts.
Parameters
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?
