Fixed and orbiting scrolls of scroll compressor components have spiral grooves known as scroll wraps. High precision contour milling using end mills is the best method to produce these scrolls. The aim of our present work is to recognize the mechanism of tool wear on end mills in end face machining and to reduce tool wear in highly efficient milling. The paper describes an effective coolant supply system to the cutting point and an appropriate tool geometry developed in the study. The following conclusions can be drawn: (1) The wear rate of the flank wear can be reduced to approximately 1/50 by supplying coolant to the cutting edge through the center hole of the tool at a cutting speed of 230 m/min (V=230 m/min). (2) The optimal back clearance angle is 5 degrees for abrasive resistance in the turning operation. (3) The wear rate of the corner edge can be reduced to 1/6 when the back clearance angle is changed from 15 degrees to 5 degrees.
