REM Surface Engineering’s Rapid ISF (Isotropic Superfinish) process for rear-axle hypoid gear sets provides the benefits of greater efficiency, as well as reduced friction, wear, and operating temperatures, via a high-speed drag-finishing production process. With drag finishing, a circular turret is located above a circular bowl containing loose, ceramic media. Parts are attached to multiple rotating spindles on the turret and immersed in and dragged through the media in the bowl below. The choice of certain media and a chemical accelerator enables the gear sets to be superfinished in less than 5 min to a surface roughness of <4 µin (0.1 µm) while maintaining gear geometry. The process can be programmed to control spindle speed and rotation direction, spindle depth, and turret speed.
