Background technique

The cylindrical grinder is a grinder that processes the outer surface and the shoulder end face of the cylindrical, conical or other shape of the workpiece. Grinders use abrasive tools to grind the surface of workpieces. Most grinders use high-speed rotating grinding wheels for grinding, and a few use oilstone, abrasive belts and other free abrasives for processing, such as honing machines, ultra-finishing machine tools, abrasive belt grinders, grinding machine polishing machines, etc. Grinders can process materials with higher hardness, such as hardened steel, cemented carbide, etc. When the cylindrical grinder is running, in order to prevent the tool from overheating, it is necessary to continuously spray cutting fluid to the tool to cool down, and the metal particles generated by grinding also flow out with the grinding fluid, and the outflowing grinding fluid needs to be filtered before it can be recycled. Because the metal slag particles produced by grinding are small, filter cloth is generally used for filtration. When the current filter equipment is in use, the filter cloth needs to be cleaned regularly. The speed of the grinding fluid flowing through the filter cloth is slow, so the filtering Slow and inefficient.
