There are many benefits to gear grinding, includingimproved gear quality, both elemental geometry, leading to lower gear noise and increased lead control which improves contact ration and gear set life. All these lead to quiet running gear sets.
Heat treated gears distort. This distortion may decrease the quality level of the gear elements-lead, profile, run-out-by one to three levels. The most significant issue is finding the ones that are bad! Heat treat change is not uniform from gear to gear, and worsens in helical gear manufacturing due to "lead-unwind."
Gear Grinding normalizes the gear manufacturing process: In fact gear quality exceed pre heat-treated quality levels after gear grinding, and can be improved to several quality levels higher depending on equipment technology. Gear grinding produces Consistent, repeatable
