Vacuum chuck of CNC processing

Vacuum chucks are mainly composed of micro porous ceramics and frames. They can also be called porous ceramic chucks, which have two characteristics:
1、 Absorb the workpiece and apply it to Vacuum chuck.
2、 Float the workpiece and apply it to the Air Floating Stage and Non-Touch Transfer System.

Frame processing matters needing attention:
Material selection: Generally it can be divided into stainless steel, aluminum alloy and granite
1、 Material cut shape: Leave the main frame material to avoid excessive deformation of the frame.
2、 Stress Relief: Stress relief of the frame material to avoid excessive warping.
3、 plane correction: so that the processing can achieve the best processing efficiency.
4、 CNC rough processing
5、 Deformation measurement: Minimize the deformation of CNC fine machining
6、 CNC finishing: eliminate the deformation of the frame material to facilitate the grinding process.
