Introduction of electroplated diamond grinding wheel
Electroplated diamond grinding wheel is mainly made of metal materials such as bronze and sintered at high temperature. The grinding wheel of electroplated diamond grinding wheel is a combined abrasive with certain strength, which is a common abrasive solidified into a certain shape (mostly a circle with a through hole in the center). Abrasive tools are generally called three elements: abrasive and consolidation.
Electroplated diamond grinding wheel is the general name of a small grinding tool with handle, which is used for electric grinder, suspension grinder and hand drill. There are many kinds, mainly including ceramic grinding head, rubber grinding head, diamond grinding head, abrasive cloth grinding head, etc. High bonding strength, good formability, high temperature resistance, good thermal conductivity and wear resistance, long service life, and can withstand heavy load.
Due to the inevitable shrinkage and deformation of electroplated diamond grinding wheel in the sintering process, the grinding wheel must be formed before use, but the dressing of the grinding wheel is very difficult. At present, the commonly used electroplated diamond grinding wheel is not only difficult to dressing, but also a large number of electroplated diamond particles will fall off during dressing, which not only consumes a large amount of dressing of the grinding wheel itself, but also has low forming accuracy. In recent years, scholars at home and abroad have carried out research on dressing metal bonded electroplated diamond grinding wheel by special machining methods such as electrolytic dressing, EDM dressing and compound dressing. Electrolytic dressing is fast, but the forming accuracy is not high. EDM dressing has high forming accuracy, which can be formed and sharpened, but the forming speed is slow. Compound dressing methods include electrolytic EDM compound dressing method, mechanochemical compound dressing method, etc. The dressing effect of electroplated diamond grinding wheel is good, but the system is complex, and the dressing problem has not been well solved. In addition, because the manufacturing process of electroplated diamond grinding wheel determines the random surface morphology of electroplated diamond grinding wheel, and the geometry and distribution of each abrasive particle are inconsistent with the edge height, there are only a few high edge tangential workpieces during grinding. The grinding quality is limited and the grinding efficiency is further improved.
