Description

technical field [0001] The invention discloses a permanent magnet type liquid magnetic abrasive tool surface finishing device and method, which belong to the field of precision finishing technology and free abrasive tools, and in particular relate to a permanent magnet type liquid magnetic abrasive tool surface finishing device and method. Background technique [0002] The traditional technology of polishing and grinding the metal plate workpiece is mainly to use the grinding wheel to grind the surface of the workpiece, which is only suitable for the grinding of general precision parts. The surface roughness after processing is often not high, and the polished thickness of the metal plate workpiece is thin. , In the case of relatively low hardness, it is easy to cause deformation and edge collapse of the workpiece, and in reality, "sticking knife" and "knife collapse" are often encountered, resulting in poor surface finish and dimensional accuracy of the workpiece. The scrap...
