The polishing machine is a kind of equipment which is widely used in the processing of hardware and electronic components. It has a wide application range and can replace manual polishing and increase power. For example, the surface polishing cylinder polishing machine can be applied to various stainless steel cylindrical containers. Polishing speed can reach 8-10m2 per hour.

In the operation of the automatic polishing machine, the polishing abrasive of the polishing machine manufacturer is very important, which directly affects the polishing effect of the product, so it is necessary to select the polishing abrasive with the appropriate characteristics according to the requirements of the polishing component. Automatic polishing machines generally select high-strength polishing abrasives to grind materials with lower tensile strength, and benefit from the use of tough silicon carbide abrasives. In addition, the material of the workpiece should be considered. When selecting the polishing abrasive, the hardness of the workpiece of the polishing machine is an important consideration. Under normal circumstances, the hardness of the polishing abrasive is 2-4 times higher than the hardness of the workpiece. Otherwise, The low-hardness abrasive will be agilely passivated during the high-speed cutting process and lose the cutting ability, so that the durability of the grinding wheel is too low, which affects the cutting power, and the processing quality cannot be ensured.

Therefore, the higher the hardness of the workpiece material, the higher the hardness of the abrasive. The selection of polishing abrasives should also take into account the chemical reactions that occur during the grinding process of the polishing machine. Experiments have shown that when the silicon carbide abrasive tool grinds the steel, the wear of the abrasive is faster than that of the corundum abrasive. Finally, it is necessary to mention that the selection of polishing abrasives is also affected by the thermal stability. Due to the high temperature of the polishing abrasive during the processing of the polishing machine, the deformation itself is formed, so that excellent thermal stability is ensured.
