Abstract
Immediately after dressing, the surface of a conventional resin-bonded diamond_wheel has several statuses. Especially, surface roughness deterioration occurs due to the decreace in the strength of abrasive bond. Before grinding, preprocessing is therefore performed using dummy materials to remove these abrasives, but the shape of the wheel may change. Therefore, we developed a repair method using laser energy for the gripping strength of grain using thermoplastic resin. The surface roughness was improved by more than 21.1%, and the repair effect was confirmed.
