Grinding workpiece clamping chuck KCHP / VKCHP

centricalprecisioncylindrical

For internal or external cylindrical grinding Large through hole (KCHP) Coolant or air passage (VKCHP) Actuation by drawbar and separate pneumatic cylinder (KCHP) Actuation by rotating air tube (VKCHP) High repeating accuracy of ≤ 0.002 mm Hermetically sealed for long-term performance Light weight and compact design Accurate top jaw location independent of chuck serial number Low maintenance Fuel injection nozzle body: Clamping of nozzle body with axial end-stop against the bore taper – Grinding of the nozzle body’s nose – Axial end-stop on tungsten carbide pin – Concentric clamping on OD Distribution disk: Internal clamping of distribution disks of hydraulic motors – Grinding of the face and the concentric bore – Low-deformation radial clamping in six bores – Compensation by means of pendulum jaws – Rigid axial end-stop for achieving a maximum flatness on the face Ring gear with internal teeth: Clamping in the pitch circle of the internal gear teeth – Grinding of the face and the centering bores – Low-deformation positioning within the pitch circle diameter – Compensation by means of pendulum jaws tted with clamping pins for positioning within the pitch circles Valve body: Outside clamping with pull-back onto axial end-stop – Grinding of the bore and the outer front section – Rigid clamping by means of part pull-back onto axial end-stop – High concentricity and tight tolerances on the linear measurement
