Characteristics of selecting grinding wheel for surface grinder
As we all know, the surface grinder focuses on grinding the workpiece through the rotation of the grinding wheel to achieve the flatness of the workpiece. Therefore, it can be said that the focus of the surface grinder is the grinding wheel. So, what is the key to the selection of grinding wheel? Today we will briefly analyze the following considerations for the selection of grinding wheel of surface grinder:
1. When the surface grinder is used to handle the hard workpiece materials, we should choose the soft grinding wheel. On the contrary, if the workpiece is soft, we should choose the hard grinding wheel.
2. When selecting the grinding wheel, the hardness of the grinding wheel shall be soft when the end grinding is more than the circumferential grinding.
3. The coolant grinding of the surface grinder is 1 ~ 2 times higher than that of the dry grinding wheel
4. When working, if the speed of the grinding wheel is relatively fast, the hardness of the grinding wheel should be slightly higher than grade 1-2
5. Under the same grinding conditions of surface grinding machine, we should know that the hardness of resin bonded grinding wheel is 1 ~ 2 orders higher than that of ceramic bonded grinding wheel
6. For workpiece materials with poor thermal conductivity, relatively soft grinding wheels shall be selected.
