Description
Technical Field
[0001] The utility model relates to the technical field of magnetic core processing, in particular to a magnetic ferrite core grinding machine. Background Art
[0002] Ferrite cores are also divided into soft and hard. Soft magnetic cores will show magnetism under the action of an external magnetic field; they will not show magnetism after the external magnetic field is removed. Hard magnetic cores will retain their magnetism even after the external magnetic field is removed after being magnetized. Ferrite cores are mainly composed of iron, manganese and zinc, and are usually called manganese-zinc ferrite. There are many processes in the processing of ferrite cores, one of which is to grind the ferrite cores with a grinder.
