PRECISION POWER CHUCK KCHP/VKCHP

PRECISION POWER CHUCK The KCHP/VKCHP precision power chucks have been specifically designed for cylindrical grinding machines. To ensure a flawless long-term operation, the chucks are hermetically sealed against contamination and are oil-filled for permanent lubrication. These design features render the chucks nearly maintenance-ree. All the precision power chucks of the f generation KCHP/VKCHP now also feature volume compen ation to prevent unwanted s loss of oil and ingress of coolant. The KCHP power chucks are actuated via a drawbar and a pneumatic cylinder mounted at the back of the...

3KCHP 160 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 3VKCHP 200 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 flatne

3KCHP 200 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 fitted with clamping pins for positioning within the pitch circle 3KCHP 110 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 me

SAP 160 Valve Compensating clamping between centers – Cylindrical grinding of the valve shaft and head – No defection of the shaft allowed – Sufficient torque transmission for OD grinding SAP 160 So Spline shaft: Compensating clamping between centers – Cylindrical grinding of various outside diameters – High concentricity – Free of distortion – free of lateral loads – No need for changeover to a comp

3KFHP 400 Gear part: Clamping of gears on pitch circle (approx. ø250) – Grinding of the bore – High concentricity required – Workpiece is first inserted into a needle cage and subsequently this assembly is clamped in chuck 3KFHP 315 Part of CVT gearbox: Clamping on OD diameter – Grinding of face and ID diameters – Must be free of deformation caused by clamping force – High concentricity and axial run-ou

KCHP-SF: simultaneous chuck As a rule, before the clamping areas of soft top jaws can be ground, they must first be turned. The advantage offered by a simultaneous chuck is that the main chuck can remain on the grinding machine while the jaws can be mounted on a simultaneous chuck. This chuck can subsequently be clamped in a three-jaw chuck or in a magnetic chuck on a lathe. The simultaneous chucks are fitted with three jaw mounting locations for both ID and OD clamping in such a way that the top jaws can be machined at the clamping section while correctly taking the clamping stroke into...

ACCESSORIES SAP SAP Standard | Compensating clamping between centers Center point (complete) The concentric chucks of Type 3KCHP can be «converted» into a compensating chuck by using an SAP kit. This allows the machining between centers of critical shaft-type workpieces. The floating clamping ring ensures that the workpieces are not subject to any deformation due to clamping forces. Intermediate jaws (thickness HZB) Top jaws (complete) Clamping ring (complete) A further advantage offered by this arrangement is that the concentric chucks do not have to be dismounted and replaced by a...
