Grinding workpiece clamping chuck KCHP / VKCHP

centricalwith coolantstandard

The KCHP/VKCHP precision power chucks have been specifically designed for cylindrical grinding machines. The chucks are hermetically sealed against contamination and are oil-filled for permanent lubrication to ensure a flawless long-term operation. These design features render the chucks nearly maintenance-free. All the precision power chucks of the generation KCHP/VKCHP now also feature volume compensation to prevent unwanted oil loss or grinding fluid ingress. Functions & Field of Application • OD and ID clamping • Large central bore (through hole) • Power chuck (KCHP) for actuation through a pneumatic cylinder • Power chuck (VKCHP) pneumatically actuated on the front-end • Ideal chuck for all cylindrical grinding machines • Advantages • High precision ≤ 0.002 mm • Low on maintenance • Hermetically sealed and lubricated • Suitable for grinding machines • Lightweight design • Precision interfaces between the base and top jaws • Do not require regrinding of clamping position after a change of jaws • Possible to interchange jaws between chucks of identical design • Standard accessories are readily available Changing jaws within micrometer tolerances is made easy! All power chucks of the KCHP/VKCHP generation feature precision jig-ground locating bores for precision ball positioning. This ensures a quick clamping jaw change, independent of the chuck, without regrinding the jaws. This feature saves valuable time and increases productivity. Under optimal conditions, the jaws can be changed with an accuracy of ≤ 0.002 mm
