After years of development, the grinding process has been very mature, especially in the processing of superhard materials is an essential process. Diamond grinding wheel as the world’s hardest material made of grinding wheels, in the grinding industry is deeply loved, today to introduce the factors that affect its blockage.
Factor one, the impact of diamond abrasive particle size
In the rough grinding of the workpiece, it is more suitable to choose a rough grinding wheel, that is, a diamond wheel with a relatively small abrasive density. Because the amount of each cut in the rough grinding is relatively large, the temperature is relatively high, so the selection of the grinding wheel is higher; And then fine grinding is suitable for the choice of fine sand wheel, because the grinding cut is relatively small, the temperature is not very high, the required chip removal, heat dissipation pores are not large, and the fine sand wheel has a better guarantee of accuracy.

Factor two, the influence of the binder
The definition of diamond grinding wheel hardness does not refer to the hardness of the abrasive material, but only the overall hardness of the grinding wheel, specifically, the difficulty of the abrasive falling off, the harder it is, the more difficult the abrasive falling off, and the easier it is. The bond is used to link the abrasive particle to the substrate, and the stronger the bond, the higher the hardness of the grinding wheel. Therefore, the harder the diamond grinding wheel is more likely to clog, because in the grinding process can certainly produce grinding chips, the greater the strength of the grinding wheel is not easy to eliminate grinding chips, and the bond strength of the small grinding wheel can make the elasticity of the gap greater, so it is not easy to clog.
The above two points are the main factors affecting the degree of blockage in the working process of diamond grinding wheel, for the different processing of our workpiece, the material of the workpiece is different, we must consider many aspects, choose their own grinding wheel, to avoid causing inconvenience to you in the work.
Various models of CBN grinding wheel and diamond grinding wheel can be customized.
