회전공구(1)를 회전시켜, 표면처리용 전극(2)이 회전공구(1)의 칼날에 대향하도록 회전공구(1)와 표면처리용 전극(2)을 회전축 구동기구(8) 및 Z축 구동기구(7)에 의해 상대 이동시켜, 방전가공용 전원(18)에 의해 회전공구(1)와 표면처리용 전극(2)사이에 전압을 인가해서 방전을 발생시킴으로써, 회전공구(1)의 외주칼날의 여유면(1a), 경사면(1b)에 개질층(19)을 형성할 수가 있다. 개질층(19)을 회전공구(1)의 칼날선단에 균일하게 형성할 수 있고 방전가공만으로 공구수명을 대폭적으로 향상시키고 또 칼날의 잘 드는 정도를 향상시킬 수가 있다. A surface treating apparatus rotates a rotating tool and moves a surface treating electrode relative to the tool via a rotating shaft driver and a Z-axis driver. A power source applies voltage to generate an electric discharge between the tool and the electrode, thereby forming a reforming layer on a peripheral flank and a rake face of the tool.
