Gear Finishing with a Nylon Lap. A Lapping Machine and Lapped Surfaces.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1996 This study aims at developing a technology that the tooth flanks of a hardened gear can be mirror-finished in a short time. We propose a simple gear finishing method using a helical gear made of nylon for the lap. This method is a lapping in which the work gear is meshed with a helical gear set at a helical angle. analogous to shaving.
