Leader Lexair Pneumatic - Low Pressure Hydraulic Collet Closers

Tri-Grip compact collet closer

Designed for use on either vertical or horizontal machining centres, the Lexair Tri-Grip collet closer maximises the raw material loading capacity of any machining centre. As the exclusive UK agent for this novel, work holding system Tamworth-based Leader Chuck Systems will provide full pre- and post-sales support.

Featuring a compact design with three closers integrated into one body the Tri-Grip unit has simplified hydraulic plumbing and an accessible-from-the-top collet locking screw which allows the part to be correctly orientated. With a maximum working pressure of 5000 psi and a drawtube force of 1.1 times the applied pressure, the Tri-Grip units provide ample grip for any machine shop’s workholding needs.

Two systems for even greater flexibility

  • Double acting, fixed-length operation maintains the height from part-to-part, the Tri-Grip units can be combined in multiple configurations on a fixture using connectors bushings. This eliminates the need for external pipe work between the units.

    Leader Chuck’s managing director, Mark Jones, says: “Using the popular 5C collet the compact Tri-Grip units can be arranged in grids which increase the loading density of any machining centre’s worktable. For vertical machining centre applications, the units can be located on a plate, which is subsequently fitted to the machine’s worktable. For horizontal machining centres applications, the Tri-Grip units can be mounted on a cube or tombstone to provide a flexible and efficient workholding solution.”
