In order to reduce the costs in wheel manufacturing and on usage of the wheels, we investigated the method of adjusting the sharpness of grinding wheels by using heat treatment and UV treatment. At first it was confirmed that heat treatment of phenol resin grinding wheels for aluminum in a furnace enabled to improve the grindability of stainless steel and to prevent swarf loading. Next it was made clear that surface treatment of grinding wheels by using UV irradiation and hot air blowing had the similar effect with the heat treatment in a furnace. These treatments reduced the force ratio in surface grinding. In these cases the affected layer was limited to the wheel surface though heat treatment in a furnace affected the whole wheel. The thickness of the layer varied with the UV irradiation time. At last we applied this technique to other resinbond wheels and the same effect was obtained for the wheels with polyester bond. However heat treatment did not improve the grindability of epoxy bond wheels with high heat resistance. In such case UV treatment was an effective method to activate flow-out of swarf.
