Precise 3-Jaw & 6-Jaw Zero-Set Fine Adjustment Self-Centering Scroll Chucks
4 micro adjustment set screws capable of assisting the chuck to achieve .0005" TIR repeatability
6-Jaw chucks invaluable for clamping delicate or thin walled parts as it producing less deformation on the parts or surface due to distribution of clamping forces over a greater area.
