ABSTRACT:
The present invention relates to a milling cutter having a cutter body and a plurality of replaceable tool cartridges circumferentially spaced about the outer periphery of the cutter body. An adjustment mechanism permits adjustment of the tool cartridges in the direction parallel to the axis of rotation of the cutter body. The adjustment mechanism includes an adjustment screw threaded into a corresponding bore in the cutter body. The head of the adjustment screw projects into an inclined throughbore in the tool cartridge. When the adjustment screw is turned, the head of the screw bears against the inner surface of the throughbore causing the tool cartridge to be axially displaced. A locking screw is tightened to secure the tool cartridge in place after it has been adjusted.
