REM Surface Engineering’s isotropic superfinishing processes increase the surface durability & bending/dynamic fatigue resistance of mechanically loaded components such as gears and bearings, rotating components such as airfoils, and many other metal-to-metal contacting or cyclically loaded components. How superfinishing is applied The component is firstly shot peened, which is a cold working process creating multiple indentations in the surface using spherical media called shot. Further, scrap CH-46 mix box spur pinions, repaired by the ISF process,. Chemically Accelerated Vibratory Finishing for high performance motorsport applications. These isotropic superfinishes achieve the highest performance ratings in terms of friction, heat, noise and wear in the bearing, gear, and turbine industries. aerospace automotve motorsports gearing off-road beatings power. 0.
