Automate an improved performance ultra polish surface system for enhanced operation

Part DescriptionHigh Performance Engine Valves
Fabrication MethodGround
MaterialSteel Alloys
Process TechnologyAutoHone, MicroTech
Equipment TypeAutohone,Drag finisher

Special engine valves for racing motors require a super polish on the stems and seats in order to improve performance. Conventional Cylindrical grinding can achieve single digit Ra values but not enough for this customer’s specifications. Bel Air designed a special media for a dry process in an automated AutoHone machine. This replaced expansive and inconsistent hand polishing with a totally automated system and reaching Ra 1-2 uin surfaces in a totally cylindrical shape.
