Super Finish--HOW TO ACHIEVE AN ISOTROPIC FINISH USING A TRADITIONAL VIBTATORY BOWL--AND WHY YOU'D WANT TO DO IT

摘要

Bearings, gears and other engineered components transmit energy and/or motion by rolling, sliding, rotating or engaging their complementary partners. Areas of metal-to-metal contact between components are of great engineering concern, because such contact points increase frictional resistance, resulting in premature wear and reduced efficiency. Vibratory bowls are commonly used in metal finishing for generic deburring. But by using non-abrasive, high-density media in conjunction with an isotropic superfinishing chemistry, vibratory bowl finishing can be used to superfinish the surfaces of complementary components to an isotropic (random) finish. This improved surface increases energy/motion transfer efficiency in the metal-to-metal contact area byreducingfriction and providing an additional number of engineering advantages.
