Abstract
An improved gear or pin cleaning assembly for polishing or grinding machines having a rotating plate is presented. One or more nozzle members are positioned within the rotating plate and a source of fluid, such as deionized water, is connected to the nozzle or nozzles to emit a pressurized stream of fluid which rinses off the gear assembly as the plate rotates. The rotating plate may contain a channel for delivering the fluid from the exterior or interior of the plate to the nozzle(s).
