Abstract
The invention provides an apparatus for positioning a cutter a tool relative to a spindle of a machine tool. The machine tool include a spindle having a rotating axis and a spindle housing for supporting the spindle for rotation about the rotating axis. The apparatus includes a shank which is adapted to be mounted to the spindle of the machine tool. A piston is provided in the shank for movement along an axis which defines an angle relative to the rotating axis of the spindle. A cutter, for machining a workpiece, is connected to the piston. A first fitting member is provided on the shank and a second fitting member is provided on the piston so as to be able to fit to the first fitting member. Each of the first and second fitting members include an abutment provided on the first and second fitting members to contact each other in the direction of the axis. A fitting recess is provided in one of the first and second fitting members and a fitting protrusion is provided on the one of the second and first fitting members for fitting into the fitting recess. The cutter is axially and circumferentially positioned relative to the axis of the movement of the piston by contacting the abutments each other and fitting the fitting protrusion into the fitting recess.
