Dynamic friction dressing of the diamond abrasive brick by W-Mo-Cr alloy

In order to solve the problem of dressing course-diamond abrasives, dressing experiments on diamond abrasive bricks with abrasive size 297μm to 420μm were conducted with W-Mo-Cr alloy as dressing material.The abrasive height consistency and the micrographs of the abrasive were measured before and after dressing.Then grinding experiments on WC material were conducted separately.Resultsindicate that the dressing method has high dressing efficiency and the abrasive height consistency of the diamond wheel has been greatly improved by 60%.The surface quality of WC material is evidently improved after dressing and the surface roughness of WC material reaches R_a0.149μm.
