Description
technical field [0001] The invention relates to the field of liquid metal polishing, and more specifically, relates to a liquid metal polishing device and method for polishing through holes by using a rotating magnetic field. Background technique [0002] Polishing mainly 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. It is a modification process on the surface of the workpiece by using polishing tools and abrasive particles or other polishing media. At present, the commonly used polishing methods include mechanical polishing, chemical polishing, and electrolytic polishing. [0003] Liquid metal Liquid metal refers to an amorphous metal, and liquid metal can be regarded as a mixture composed of positive ion fluid and free electron gas. Liquid metal is also an amorphous, flowing liquid metal. Liquid metal polishing refers to the polishing of the workpiece with a li...
