Description

technical field [0001] The invention belongs to the field of mold manufacturing, in particular to a device for processing the surface of a mold by laser. Background technique [0002] Some molds used in metal, glass, plastic and other manufacturing industries require high-quality surface finish and roughness, which directly affects product quality, wear resistance, optical properties and visual effects. The pre-processing of the mold is processed by lathes, grinders, milling machines, wire cutting, electric sparks and other equipment. The surface roughness is relatively large. To obtain a high degree of finish, there are currently two traditional methods for surface improvement. One is to use fine emery wheels. After grinding, use manual grinding and polishing, and use special cloth with light corrosive liquid or diamond paste to repeatedly rub against the surface of the mold to form a mirror effect. However, manual grinding and polishing are subject to some limitations, su...

AI Technical Summary

Problems solved by technology

However, manual grinding and polishing are subject to some limitations, such as the need for skilled skills and experience, but it is also difficult to ensure the consistency and reproducibility of the mirror surface, and it is also difficult to ensure the accuracy of dimensions by manual grinding and polishing, and this process is very time-consuming

The other is to use machine grinding for processing. The workpiece is placed on a continuously rotating disc. The disc is covered with metallographic polishing cloth, and the workpiece also rotates with the disc. At the same time, corrosive polishing liquid or diamond is sprayed. Paste, repeated friction between the workpiece and the cloth on the disc can also achieve the mirror effect, but the disadvantage is that it cannot process special-shaped parts, because the trajectory is inconsistent during rotation, resulting in poor flatness after processing, low processing efficiency, and the polishing liquid is corrosive ,polluted environment
