Unique Workholding Systems for Aerospace Machining

The Loc-Down™ and Loc-Jaw™ systems are ideal workholding solutions for high speed machining applications on large parts.

Mitee-Bite‘s (Center Ossipee, NH) Loc-Down™ System is a simple way of quickly attaching and removing plates or workpieces from a sub-plate and is best described as a “headless bolt” with a simple ball-locking mechanism. The system saves the time required to completely remove a bolt with minimal tooling interference.

Although primarily designed to quickly locate and secure large aerospace parts for high speed machining, it can be implemented into many designs that previously required a standard bolt. The Loc-Down also develops 100 ft-lb for every pound of torque.

The Loc-Jaw™ System for 4^th and 5^th axis machining is a design unique to the industry requiring no material preparation. The rails and gripper towers are serrated to provide a solid and easily adjustable base.

The Loc-Jaw™ has a clamping range of 0.5 in to 4.0 in, is capable of penetrating .060 in deep per gripper and produces over 6,000 lb of holding force. The low profile grippers hold on only .125 in allowing full access to all work surfaces including the bottom face.

A centering disk can be mounted to bottom of base for quick location on faceplates having centering hole feature. The base is also configured with two drill bushings for precise locating using the included diamond and tapered pins.
