However, superfinished gears are still not widely used in automotive transmissions and axles. Ra. Moreover, evidence suggests that isotropic superfinishing imparts a finish that increases gear durability and service life in the field. 1. This isotropic finish requires no break-in, maintains cooler gearbox operational temperatures, generates no metal chips and most importantly, dramatically reduces the initiation of future pitting and/or metallurgical. As a polishing process, the REM Process has been shown to be the.
