Effects of swarf discharge of continuous chip pocket in spiral tool

Abstract

In general, current fixed-abrasive tools are subjected to intermittent dressing when loading occurs, which continues until they lose their grinding and polishing capabilities. The dressing process has adverse effects, such as reduced operating efficiency and tool lifetime and increased cost and environmental burden. The authors propose a fixed-abrasive tool with a spiral groove on the tool surface to eliminate or decrease swarf loading. The spiral groove, which is produced by a spiral wire wound around the tool, allows continuous evacuation of swarf and prolongs tool life. Grinding experiments confirmed that this spiral groove tool has almost no swarf loading while conventional fixed-abrasive tool are subject to loading. It was also shown that a mirror surface can be achieved with the spiral tool.
