Usage and advantages:

When there is a need to machine variety of diameters or different work pieces at high accuracy, this configuration offers the ability and the flexibility to quickly remove the chuck along with its top jaws as one piece and change it with another one without dismounting the air feed tube or the adaptor on the machine spindle nose. Thus continue machining the next piece. The new chuck will provide the same high accuracy. This configuration saves on set up time and minimizes adjustment.

PML-PAL offers Quick Change option in any chuck configuration including diaphragm chuck. Quick change chuck is also known as Back Air Ported chuck. There are two air ports at the back of the chuck.

For long work pieces clamping, it is recommended to order the QC chuck with through hole.
