摘要

Ensuring the contour accuracy and protrusion height of the abrasive particles of the metal-bonded grinding wheel (MBGW) used in electrochemical grinding (ECG) is quite challenging. To this end, the current study proposed an on-machine hybridized dressing technology combining mechanical grinding truing (MGT) and reversing electrochemical sharpening (RES). It was applied to a CBN abrasive conductive grinding wheel sintered with bronze bonds in a certain bearing ring’s internal cylindrical plunge ECG. The MGT and RES experiments were conducted using different process parameters. By comparing the protrusion heights of the abrasive particles after RES, it was found that the optimal dressing effect on the grinding wheel was achieved at an electrolysis voltage of 10 V and a processing time of 2 min. The grinding wheel, dressed with the above process parameters, was used to conduct the machining experiment on the bearing ring’s internal cylindrical plunge ECG. A uniform distribution of mechanical grinding traces on the machined surface was achieved, with a surface roughness Ra of 0.253 μm. The MBGW dressed by the proposed on-machine hybridized MGT + RES dressing technology could meet the bearing ring’s internal cylindrical plunge ECG machining requirements.
