The faceplate drawbar operated expanding mandrel can be used on any machine with drawbar facilities, for general turning and grinding operations. Adaptor plates made to suit the machine mounting can be manufactured by PTG Workholding, or the customer. Component end-locators, solid type or compensating (for out of square locating faces) can also be supplied or manufactured to your requirements.

The natural pull-back action of the sleeve ensures the component is hard against the location face. There is an over-expansion stop built into the expander pin to avoid over-stressing the expanding sleeve.
