Contact SupplierWe offer our hydraulically expanding & contracting jelly filled mandrels, arbors & chucks for gear grinding operation. With use of our products one can achieve high precision clamping & control runout & perpendicularity parameters consistently. This can be used for gear manufacturing industries and is useful for czepel, reishauer, maag, hofler, & wmw. The mandrel is made with split less elastomer steel by manual actuation the sleeve expanded & job clamp rigidly, it gives hi accuracy & reliable performance for long life.
Gears always be grind with axial clamping devices, no face clamping is advisable.
