Problems solved by technology

[0002] Polishing technology refers to the use of mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and smooth surface, and the use of polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece; In the magnetic electrolytic compound polishing, the direction of the magnetic field is very important, and the static magnetic field perpendicular to the direction of the electric field is easy to realize. Therefore, in the traditional magnetic electrolytic compound polishing, a static magnetic field perpendicular to the electric field is often added, but the volume of the traditional polishing head is very small. Small, the magnetic field strength is also very weak, the influence on the magnetic electrolytic composite polishing is limited, the polishing quality is not ideal, the magnetic field direction and magnetic field size of this kind of polishing head cannot be changed according to the polishing requirements
