Abstract
A milling cutter for performing milling work on a work comprises a cutter body having a ring-shaped structure. A plurality of first tips are disposed on an inner peripheral surface of the cutter body along the circumferential direction thereof with a distance between adjacent ones and adapted to perform rough cutting work on a pin, a journal of the work and journal thrusts disposed at both ends of the journal. A plurality of second tips are disposed on both side portions of the inner peripheral surface of the cutter body along a circumferential direction thereof with a distance between adjacent ones and adapted to perform rough cutting work on side surfaces of counterweights disposed at both end sides of the pin and the journal of the work. A flat drag disposed on an inner peripheral portion of the cutter body and adapted to perform a flat cutting work on the journal thrusts. The flat drag has a cutting edge and is set to the cutter body in a manner that a deviation of the cutting edge of the flat drag in an axial direction of the cutter body is maximized with respect to deviations of the cutting edges of the first tips. According to such structure, since the flat drag performs the surface flat work to improve the surface roughness of the journal thrust, the finish work on the journal thrust can be eliminated, improving productivity.
