The face-plate nut operated expanding mandrel can be used on any machine with no drawbar facilitity, for general turning and grinding operations. Adaptor plates made to suit the machine mounting can be manufactured by PTG Workholding Ltd., or the customer. Component end locators, solid-type or compensating (for out-of-square locating faces) can also be supplied or manufactured by the customer.

The natural pull-back action of the sleeve ensures the component is hard against the location face.
