Development of fixed-abrasive tool with spiral groove for decreasing the loading

The authors propose a fixed-abrasive tool with spiral groove on its surface, to eliminate or decrease the loading of swarf. The spiral groove, which is produced by a spiral wire wound around the tool, allows continuous evacuation of swarf and elongates the tool life. Through grinding experiments, it was confirmed that our spiral groove tool makes almost no loading of swarf while conventional fixed-abrasive tools easily make it. It was also shown that the spiral groove tool realizes a mirror finish even with ultra fine abrasive grains.
