ABSTRACT:
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.
