Preparation of a novel 3D printed grinding wheel with linear cooling channels and study on the grinding performance

In this study, a novel type of diamond grinding wheel with linear cooling channels (GWLCC) is proposed, and an innovative manufacturing process is employed to develop this new grinding wheel. Grinding experiments conducted on four types of hard and brittle materials demonstrate that the grinding performance of GWLCC is better than that of conventional dense grinding wheels. Furthermore, the grinding performance of GWLCC was further investigated by comparing the abrasive ratio and working current under various grinding process parameters. The results indicate that the grinding efficiency of the grinding wheel is positively correlated with the rotating speed, achieving maximum efficiency at a rotating speed of 300 r/min. Additionally, variations in feed speed significantly affect the grinding force, but to protect the grinding equipment, the value shouldn’t be too large.
