摘要：
In view of the difficulty of dressing super-abrasive grinding wheels, a dressing method was proposed, which was a combination of the grain extrusion and grinding under the constraints of diamond profiles. This method was based on the characteristics of the great differences in strength between diamond and ordinary materials and the principles were as follows. Diamond tools with precision shapes on the surfaces produced high-strength surfaces with constraints through high-speed rotation. Free grains under the constraints of diamond constraint profiles had a squeeze-scratching effect on the grinding wheels and destroyed the adhesive of the grinding wheels to complete the dressing of grinding wheels in high efficiency. Meanwhile, the shape of the grinding wheels was further refined by the micro-grinding effect of the high-strength diamond abrasives of the dressing tools. Herein, the formation of the constraint profiles and the mechanism of extrusion and cutting of the free grinding grains under the diamond constraint profile were analyzed. The composition and characteristics of the extruded dressing systems were introduced. The influence laws of parameters such as dressing force, grinding speed and free grinding grain were explored experimentally. The results show that precision dressing of ultra-hard abrasive grinding wheels in high efficiency may be achieved by extrusion of free grains under the constraints of diamond profiles. © 2020, China Mechanical Engineering Magazine Office.
