Faceplate Nut Operated Mandrel
The face-plate nut operated expanding mandrel can be used on any machine with no drawbar facility, for general turning and grinding operations. These are a popular choice for milling fixture locators.
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 manufactured by the customer.
The natural pullback action of the sleeve ensures the component is hard against the location face.
For maximum efficiency, expansion sleeves should be pre-loaded to maintain contact with mandrel double-angles at all times.
