Step 4: Detection and classification: Use a detection machine to detect the inductance of the cooled magnetic core and automatically classify it. Unqualified products will be downgraded and sold out, and the scrap products will be sold out to the scrap collection station. Step 5: Arrange the parts automatically by the arrangement machine; Step 6: Grinding. The qualified magnetic blocks are sent to a grinding machine for grinding. There are two production lines for the grinding process. Before grinding on the first production line, heating is required. The heating melts the rosin to bond the small products, and then grinding is carried out. The second production line performs rough grinding, fine grinding and mirror grinding operations on the magnetic blocks, and the mirror grinding machine in this production line is of a closed type; Step 7: Cleaning. After grinding, there will be grinding residues remaining on the surface of the products, and water needs to be added for cleaning; Step 8: Drying. The products after cleaning need to be dried in an oven or directly air-dried; Step 9: Inspection, packaging and warehousing. The products are manually selected, packaged and warehoused according to different qualities, and all are sold externally.
