Abstract

A metal cutting tool holder and adjusting mechanism having a rotational drive; a housing and cam mounted therein for rotation by the rotational drive; a cam follower mounted on the cam for axial motion; a wedge block axially slidably contained in the housing and adapted to be moved axially by the cam follower; the wedge block having a tapered transverse surface; and a tool holder block transversely slidably contained in the housing and adjacent the wedge block; the tool holder block having a tapered surface thereon slidably engaging the tapered surface of the wedge block but which is a reverse taper compared to the taper of the wedge block, so that the rotation of the motor drives the wedge block axially, and the tapered surfaces cause the tool holder block to move in a radial direction of the wedge block. In alternative embodiments, unidirectional controls cause the rotational drive to move the wedge block in the opposite direction. The controls include a comparative voltage electrical control system. The device provides for tool adjustment for automatic control for metal cutting tools.
