TF25-OG Overgrip Pickoff Collets for Cincom M20 and L20 Swiss Turning Centers

摘要

Overgrip collets, also referred to as over-the-shoulder collets, are used on a pick-off spindle when it is required to clear a shoulder and grip on a smaller diameter beyond. A good example of this type of part would be a screw. In collaboration with Citizen Machinery Tech Center, managed by Bob Meunier, Hardinge has developed and now manufactures standard TF-25 OG overgrip collets for Cincom M20 and L20 lathes. Extra spread is required to open the collet wide enough to go over the screw head or larger diameter. Hardinge's collet design incorporates teardrop slots and reduced wall thickness for maximum flexibility for the overgrip pick-off process.
