[0002] Machine tools refer to machines used to manufacture machines, also known as machine tools or machine tools, and are usually referred to as machine tools. They are generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. During the processing of metal parts by machine tools, there is a lot of friction between the interface between the tool and the workpiece, and between the tool and the chips, which increases the cutting force, cutting heat, and workpiece deformation, leading to tool wear, and also affects the quality of the processed surface of the workpiece. Therefore, in order to improve the processing accuracy, coolant is usually sprayed during the processing. During the processing of machine tools, a large amount of metal chips will be generated, and these metal chips will remain in the sprayed coolant, which will result in the coolant being unable to be used after recovery, resulting in a waste of resources and an increase in processing costs. Therefore, it is necessary to design a machine tool coolant filter device to effectively solve the above technical problems. Utility Model Content
