Laser processing is a novel processing technology, and has the advantages of high efficiency, high flexibility and the like. The characteristics and significance of the laser polishing technology are the development of modern manufacturing industry, and higher requirements are provided for surface precision processing. The polishing process, an important process means in the manufacturing industry, affects not only the service performance of the product but also the grade of the product. The laser polishing process is to melt and evaporate the raised thin layer on the surface of the metal material by applying a focused laser beam spot to the rough original metal surface. The melted material flows under the action of surface tension and gravity of the material, fills the concave part of the metal surface and solidifies, and finally the ideal polished material surface is obtained. Through the control of the fiber laser, the output energy during laser polishing and the action layer thickness of the metal material are very small and only occur on the material layer with the thickness of micron, so that a large-area rough surface cannot be caused like the common laser beam processing metal. The laser polishing technology generally uses a fiber laser or a pulse laser and the like to polish metal surfaces, but the metal curved surface needs to be preheated for a period of time first and then polished, so that the problems of long polishing time, low polishing efficiency, difficulty in polishing the curved surface and the like exist.
