Carr Lock Fixture Machining Kits
are extremely useful for machining a fixture using the Carr Lock mounting holes as an absolute reference. The kit consists of four extra-long Carr Lock Clamps, used together with four precision-height spacers, providing ample clearance underneath the fixture plate to allow through-hole machining without damaging the subplate. The kit also includes an extra four spacers to use as additional supports under large plates, all in a handy carrying case. Made in USA.
Application Information
Design Considerations & Safety Precautions
Carr Lock Clamps should only be used to locate and clamp flat plates on machine tools. Each top plate should have one Carr Lock mount designated as its primary reference point, and one as its secondary reference point. These two mounts should be as far apart as possible. The secondary reference point should have a relieved liner to avoid redundant location (binding). Additional Carr Lock Clamps can be used for more clamping force, but these should be installed in clearance holes, not locating liners. Note that the same Carr Lock Clamp fits into any type of liner or a clearance hole. Carr Lock Clamps must be used with Carr Lock Receiver Bushings for proper operation. Plate thickness must be +/-.005" to achieve full clamping force.
