Chuck or collet holder assembly is integrated into the machine by selecting a suitable side according to the shape and technical characteristics of the part.

It fixes the relevant part tightly during the rotation of the part and the chip removal from the part, preventing possible hazards and facilitating the chip removal process. The tightening and loosening process is carried out practically with the on-off air valve.

The chuck actuation device needs a pneumatic or hydraulic power source, depending on the state of the chuck.
