ABSTRACT:
The subject invention relates to an improved assembly for mounting a finishing insert in a milling cutter. More particularly, the subject invention facilitates the adjustment of the tilt of a finishing insert relative to a milling cutter to improve the finish of a workpiece. In accordance with the subject invention, a milling cutter is provided with a finishing insert pocket having a planar bottom wall disposed at an inclined angle relative to the planar surface of the cutter. A locating seat, having a finishing insert fixedly mounted therein, is adjustably mounted within the insert pocket. By adjusting the position of the locating seat relative to the insert pocket, the angle of the cutting edge of the finishing insert, relative to the milling cutter is varied. In a preferred embodiment of the subject invention, both the insert pocket and the locating seat include complimentary arcuate walls to provide additional support during the cutting operation.
