    In recent years, the automotive industry has been demanding high-efficiency processing of gears in terms of the trend in the increase in the number of transmissions shipped and the number of stages for multistage automatic transmissions. This trend is prevailing over not only the automotive industry, but also manufacturers in all fields including construction machinery and various reduction gears. With such a background, skiving cutting that mainly uses an internal gear has been attracting significant attention recently. Mitsubishi Heavy Industries Machine Tool Co., Ltd. also developed the MSS300 super skiving machine, which has both the optimum machine rigidity and control technology for skiving cutting. In addition, we developed a super skiving cutter, which is advantageous for tool life, which tends to be a problem in skiving cutting. This paper presents these gear cutting systems.
