Description

Technical Field

[0001] The utility model relates to the technical field of magnetic material processing, in particular to a grinding machine for grinding magnetic materials. Background Art

[0002] Magnetic materials refer to materials that can produce magnetic response under the action of external magnetic field. They have magnetic domain structure, that is, the area where microscopic magnetic moments are arranged in an orderly manner. According to their different magnetic properties, magnetic materials can be divided into soft magnetic materials and hard magnetic materials.

[0003] Soft magnetic materials: refers to materials with high magnetic permeability and low coercive force, such as ferrite, pure iron, low carbon steel, etc. They are easy to magnetize and demagnetize and are suitable for magnetic cores in electromagnetic equipment.

[0004] Hard magnetic materials: refers to materials with low magnetic permeability and high coercivity, such as aluminum nickel cobalt, iron chromium cobalt, samarium cobalt, etc. They are not easily magnetized and demagnetized and are suitable for permanent magnets and magnetic recording media.

[0005] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, super finishing machines, belt grinders, grinders and polishing machines.

[0006] Grinding machines can process materials with higher hardness, such as hardened steel, cemented carbide, etc., and can also process brittle materials, such as glass and granite. Grinding machines can perform high-precision grinding with very small surface roughness, and can also perform high-efficiency grinding, such as high-power grinding.

[0007] At present, after some magnetic materials are shaped, in order to avoid the presence of barbs or bumps on the surface, which may affect the size coordination in the later stage, the surface of the magnetic materials needs to be ground and leveled to remove the uneven surface. However, most grinding machine structures are single grinding disc structures. When grinding, the debris can easily splash out along the grinding direction. Since magnetic materials can easily affect electrical equipment, it is necessary to design a protective structure that can prevent the debris from splashing out in the grinding rotation direction of the grinding disc when grinding magnetic materials, so as to improve the safety of the processing process.
