Nut Operated Between-Centres Expanding Mandrel
(TEC-810-100)
The nut operated between-centres expanding mandrel is typically mounted between 60-degree centres and can be driven using a carrier or drive plate via the drive flat. A simple component end locator can be fitted at diameter L, if required.
A ground diameter (G) allows the mandrel to be adapted for faceplate mounting using an adaptor plate. Adaptor plates to suit your machine’s mounting can be supplied by Thame Workholding. Component end-locators—both solid and compensating types for out-of-square locating faces—are also available.
These mandrels are generally used for small-batch grinding operations and are hand-operated with conventional spanners. They are also well suited to inspection tasks.
For optimal performance, expansion sleeves should be pre-loaded to maintain constant contact with the mandrel’s double-angled surfaces.
