This research presented a new guide mechanism and belt driving theory of the abrasive band polishing for inner aperture, satisfied the driving requirement of abrasive belt leading smoothly into grinding area, realized the band grinding and band polishing of inner aperture, developed a abrasive band polishing headstock for of the ball track of ball bearing and roller bearing individually adopting a way of curvature concave oscillating and vibrating, researched the process regular and fundamental process method and parameter of abrasive band polishing of ball track. The results of experiments and tests showed that the surface roughness of ball track by abrasive band polishing can reach Ra0.02μm, and the original geometric cross section shape precision of ball track can be kept.
