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

SwissChuck Precision Workholding / 3KCHP200 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 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

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

SwissChuck Precision Workholding / The preload ring is mounted with the matching cylindrical pins as shown in the illustration on the right. The top jaws for ID clamping are subsequently preloaded towards the outside. This allows that the clamping sections can be ground while a preload is applied. 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...

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...
