Mounting System Makes Attaching, Removing Fixtures Precise And EasyKurt’s PinLock system makes attaching and removing fixtures, subplates, and vises from machining centers precise, fast, and easy. It is also ideal for setting up and interchanging multiple pallets for a series of machining centers.

What’s unique about Kurt’s PinLock is its helical extraction design. This feature aids in overcoming binding in side load conditions and enhances the removal of the PinLock in any application.

Kurt’s PinLock system uses a pin assembly to engage and create a locking force with line contact, as opposed to other competitive systems that use point contact. The Kurt PinLock system also is interchangeable with competitive ball locking systems.

The PinLock system consists of high precision pins, bushings, and liners that provide locating repeatability up to ±0.0005 inch. Manufactured to Kurt’s high precision standards, PinLock shanks and bushings are precision machined of heat-treated, alloy steel with a black oxide finish.

PinLock liner bushings are available for fixture plate thickness of 0.75 and 1.00 inch for the 20, 25, and 30 mm sizes. The larger size PinLock liner bushings are available for 0.75, 1.0, 1.5, and 2.0 inch fixture plate thicknesses. Back mount and front mount receiver bushings are available for receiver plate thickness of 0.75 to 2.0 inches.
