Kurt’s PinLock system is designed to ease attachment and removal of fixtures, subplates and vises from machining centers. It also is suitable for setting up and interchanging multiple pallets for a series of machining centers.
The system’s helical extraction design helps overcome binding in side-load conditions and enhances its removal in virtually any application, the company says. It uses a pin assembly to engage and create a locking force with line contact rather than point contact. It also is interchangeable with ball-locking systems. The system consists of high-precision pins, bushings and liners that provide locating repeatability ranging to ±0.0005". Shanks and bushings are made of heat-treated, alloy steel with a black-oxide finish.
Liner bushings are available for fixture plate thickness of 0.75" and 1" for 20-, 25- and 30-mm sizes. Larger-sized liner bushings are available for 0.75", 1", 1.5" and 2" fixture-plate thicknesses. Back-mount and front-mount receiver bushings are available for receiver plates between 0.75" and 2" thick.
