Laser polishing is a non-contact materials surface polishing technology, the surface of the material can be polished without wasting its own materials, which is a feature that other polishing processes do not possess.Laser polishing technology is a surface processing technology with the advantages of high precision, high efficiency and non-pollution.In order to better study the laser polishing technology of steel materials,the development of laser polishing for steel materials at home and abroad in recent years was summarized in detail.The development trend of laser polishing for steel materials was introduced from the aspects of laser selection and simulation model establishment.The experimental results show that the surface roughness of the material after laser polishing is much lower than the initial surface
