1) Does superfinishing benefit parts that have already broken-in to a decent polish, or is it mostly of value for OEMs who need to get maximum efficiency with minimal break-in?
2) Can superfinishing be used in conjuction with shot peening and not causing excessive damage to the gear profile?
3) It would seem that chemically accelerated vibratory finishing is being used for these types of parts. Is that the state-of-the art in superfinishing for a reasonable cost? (My intended use is racing, but my budget is more value-driven)
