Powerhold Soft Blank Top Jaws


Powerhold Soft Blank Top Jaws
  • When a workpiece must be gripped on a surface which has already been machined or ground, soft blank steel top jaws must be used, since serrated jaws will mar the machined surface. The jaws, when closed on the part, must hold it concentric with the center line of the spindle within a specified tolerance. Most commonly, soft blank top jaws are bored in place to the diameter to be held for best results.
