摘要

A gear shaper effects a gear shaper cutting method by dry cutting, using a pinion cutter made of high-speed tool steel at a high efficiency. The pinion cutter of the gear shaper is coated, at least on the flank thereof, with at least one layer of film having a composition comprising: (Ti(1-x) Alx )(Ny C(1-y) ), wherein 0.2≤x≤0.9 and 0.2≤y≤1.0. Gear shaper cutting is performed at a cutting speed of 300m/min or less.
