Electrodeposited diamond wheels for finish grinding require fine-grain diamonds. Promoting a reexamination of electrodeposition conditions. Initially, a previously proposed method involving distribution of diamond grit onto the wheel surface in an electrodeposition fluid was considered. This method uses two concentric cylinders and a J-type nozzle, both made of glass, with the inner cylinder containing a suspension of diamond grit in the electrodeposition fluid, and the outer cylinder containing electrodeposition liquid only. Improvements were made in the shape and dimensions on the inner cylinder, and the angle of tilt of the nozzle was changed from 60° to 70°. Electrodeposited diamond wheels were manufactured using the improved method, and grinding performance was then examined from the point of view of wheel wear and finished surface roughness. It is concluded that a current density 1A/m2yields finish grinding wheel having good performance.
