◆The world's first mass-produced tooth profile created by end mill processing. Its precision ensures perfect transmission to the drive chain. In response to requests for ISA quality for drives, we began manufacturing and selling drive sprockets. In pursuit of performance that is as good as that of driven gear, we have used SCM heat refining agents to perform NC processing down to the tooth profile, carburizing it, and shot peening.As a result, we have achieved extraordinary accuracy, strength, and wear resistance. It has come true.
