MILLING CUTTER

摘要

PURPOSE: A milling cutter is provided to increase the accuracy of processing work since the movement of a milling cutter body due to centrifugal force is minimized even in high speed rotation. CONSTITUTION: A milling cutter comprises first and second bodies(10,20). The first body has the shape of an annular ring. The first body has an insert coupling groove and a first thread portion(13). The multiple cutting inserts(11) are combined with the insert coupling groove. The second body has a second thread portion(22) and a supporting unit(21). The second thread portion is coupled with the first thread portion of the first body. The supporting unit is contacted with the first body to support the first body in the direction of a rotary shaft(A). The first body is made of material having higher strength than that of the second body. The supporting unit of the second body is made of inclines.
