CNC control system two jaw pneumatic chuck
fixtures for lathefixtures for lathefixtures for lathefixtures for lathefixtures for lathefixtures for lathefixtures for lathefixtures for lathe
Technical features:
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 service life, and it can clamp siphon, three-way.
2. Applicable to all kinds of CNC lathes.
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?
