Modular Mandrel System
PTG produce and supply precision expanding mandrels capable of automatic clamping in component bores, achieving the highest accuracy and holding power to resist the cutting forces imposed on the work piece.
PTG’s modular mandrel system provides the following benefits:
- Our unique double-angle principle allows for fast loading and unloading of components.
A standard expansion range of 0.8mm (0.32”). - Guaranteed accuracy of 0.013mm (0.0005”) T.I.R., or closer if desired.
- Greater holding power by applying pressure evenly along the length of the sleeve.
- No need to hold the work to close bore tolerance.
- One mandrel can accommodate a wide range of sleeve sizes.
- Pull-back of component onto end locator for positive location.
- PTG Workholding are generally able to recondition arbors by re-grinding the angles to return mandrels to their original accuracy.
