The KCHP/VKCHP type chucks are specifically designed for cylindrical grinding machines. Every chuck is filled with oil to guarantee an efficient chuck operation. The sealed design of these chucks has been further improved to either prevent contamination from swarf and coolant or oil loss. This makes our chucks nearly maintenance-free. The whole chuck design is aimed to ensure long-term accuracy and performance.
The KCHP style chuck features a through hole and is drawbar-actuated, typically by a pneumatic cylinder at the back of the machine spindle. The VKCHP style chuck features a coolant or air passage through the center and is actuated by a rotating air tube.
Innovation
Every single chuck of the new generation KCHP/VKCHP type features precision jig ground locating holes for accurate top jaw location. All locating holes are machined on the chuck under load. Repeating accuracy ≤ 0.002 mm. Changing the top jaws between same size chucks is now possible with consistent accuracy. This means: no re-grinding of top jaws, time saving and increased productivity.
