St. Mary Spin Roll Fixture for Grinding - 525-M

The original and basic Spin Roll. Simply mount this compact, portable, lightweight workholder on a suitable machine, insert the workpiece between the three intermeshing contact rolls and against the adjustable end stop. Tighten the clamping knob (no additional clamping, fitting or adjusting is necessary). Turn the hand crank (on the shaft of one contact roll). All rolls revolve and rotate the piece on its own circumference, achieving precise concentricity while maintaining linear position. All set for easy, efficient, accurate grinding or other machining. Workpieces remove easily, Spin Roll assures exact duplication on multiple runs.
