Cutting Tool for Rough and Finish Milling

摘要

A milling cutter ( 10 ) comprises a cutter body ( 12 ) having at least two operational annular rings ( 13, 14 ). An outer ring ( 13 ) is provided for rough milling and includes a plurality of cutting inserts spaced about the periphery of the cutter body. Positioned radially inward of the outer ring ( 13 ) is at least one ring ( 14 ) comprises a coating of abrasive material. As a result, a workpiece can be both tough and finish milled by a single milling cutter ( 10 ) with the rough cutting inserts ( 18 ) and the abrasive material.
