ABSTRACT:
A rotary tool holder for use with an automatic or semi-automatic tool grinding machine is disclosed. The tool holder includes a rotating collet and spindle. The spindle is driven through a torque limiting coupling for protection against lock up. A shaft is connected to the spindle through the torque limiting coupling which includes a disc spring made up of a plurality of concave-convex shaped discs in frictional engagement with the shaft and the spindle. The disc spring will slip at a given torque during lock up. A fluid responsive collet actuator is provided for automatic opening and closing of the collet.
