MILLING CUTTER FOR PROCESSING ROTARY MILLING MACHINE HAVING THREE MILLING CUTTERS SMOOTHLY WITHOUT VIBRATION

摘要

PURPOSE: A milling cutter for processing a rotary milling machine is provided to prevent the breakage of a tool by improving strength and to perform smooth milling without vibration. CONSTITUTION: A milling cutter(10) has three milling cutter edges(27C). The milling cutter edges are unified into the milling cutter. The milling cutter includes a milling cutter fixing unit(15). The three milling cutter edges are extended to the central line of the milling cutter from the outer face of the milling cutter. A radial outermost end portion of the three milling cutter edges is placed behind each front end point of the cutter edges. The center of the radius of the cutter edges is positioned aside the radial central line facing the milling cutter fixing unit.
