Description
Hardened top jaws are designed for clamping unmachined surfaces of the parts within initial operations. Clamping surfaces of jaws are provided with teeth which engage the part while clamping, balancing the deviations from the norm and increasing the index of friction. For high precision and concentricity between clamping and processed diameters use soft top jaws type PPM.
Hardened top jaws are interchangeable with top jaws produced by leading manufacturers (SMW-AutoBlok, Schunk, KITAGAWA, AUTO Strong, etc.).
Any type of hardened top jaws should be placed so that the clamping of the part occurs in the middle of the clamping stroke of the base jaw.
