Description

technical field [0001] The invention belongs to the technical field related to surface finishing of metal materials, and more specifically relates to a micro-beam plasma polishing device and method for curved metal parts. Background technique [0002] With the increasing demands on the quality, operating cost and multi-functionality of polished products, in order to obtain workpieces with acceptable surface roughness, the surface needs to be polished in the final step of workpiece preparation. Polishing refers to the processing method of reducing the surface roughness of the workpiece to obtain a bright and flat surface. Traditional polishing methods use polishing tools and abrasive particles or other polishing media to precisely process the surface of the workpiece. Under the existing technology, ordinary polishing machines can process simple surfaces such as planes, but they cannot process curved surfaces, which are prone to grinding marks, uneven grinding, and poor polis...
