Ideally Suitable For Scroll Machining!
MDC Master Jaw・Diaphragm Chuck
Best choice for high precision finish operation, and cylindrical grinding operation.
The clamping force is the spring reaction force of the diaphragm, which has an elastic recovery accuracy of 0.002 TIR.
The structure is resistant to frictional wear, chips, and polishing dust, so it maintains high-precision clamping for a long time.
The standard version has a built-in pneumatic cylinder for easy clamping.
The retraction function works effectively in clamping the outside diameter, and the parallelism between the axial dimension and the datun surface is excellent.
The jaws are heat-treated to a high hardness and polished for easy replacement and high accuracy.
Diaphragm chuck is equipped with high-precision elastic restoring force.
Diaphragm chucks are used in precision finishing operations because of their high-precision elasticity and resilience, and because they are unlikely to be affected in precision by wear or the intrusion of polishing dust. We use disphragm chuck for finishing turning and grinding, for scroll compressor scroll machining, and for the main body of gear chucks for pitch line datum.
Diaphragm chucks were developed by N.A. Woodworth [now FORKARDT], and we have been designing and manufacturing them under license throughout Asia for many years.
