The abrasive flow mirror polishing equipment uses a vertically corresponding plunger reciprocating extrusion flexible elastic grinding paste to flow through the workpiece fixture that needs to be polished for mirror polishing processing. The equipment is mainly used for precision mirror polishing of alloy molds, tungsten steel molds, aluminum alloy extrusion molds, wire drawing molds, spray molds, drawing molds, and other molds. Generally, one or more pieces are completed in a few minutes, with a removal rate of micrometers, It can also be used for final processing after heat treatment and surface treatment, with consistent removal rate, effectively reducing product inconsistency and scrapping caused by human factors, and achieving surface visual effects that cannot be achieved manually. The product can also be used for deburring and polishing the internal surfaces of cross holes, porous, microporous, long holes, deep holes, irregular holes, curved holes, etc. It has very high efficiency in deburring and polishing the inner walls of food, medical, chemical components, as well as complex surface processing such as impellers and blades.
