Method and device for grinding and polishing parts and molds by mixing laser

Abstract

The invention discloses a method and a device for grinding and polishing parts and molds by mixing laser. The method comprises the following steps that firstly, a workpiece surface is irradiated by using a continuous laser, and a material characteristic of the workpiece is matched to carry out coarse grinding according to specific technological parameters; then, a pulse laser, or a continuous laser and pulsed laser alternate grinding mode is adopted to complete a whole automatic non-contact type grinding and polishing process. The method and the device have the advantages that the implementation is simple, the temperature of a part body cannot be influenced in the machining process, and the influence on the precision of the part is avoided, and certain complex geometrical surfaces which cannot be machined by a traditional method can be machined.

Description

technical field [0001] The invention relates to a method and a device for mixing laser grinding and polishing parts and molds. Background technique [0002] The surface finish of the product will affect the mechanical properties, optical properties, corrosion resistance of the product and the user's visual effect on the product. Surface grinding and polishing is labor-intensive and time-consuming. Grinding and polishing some parts with complex shapes by traditional methods accounts for about 30%-50% of the total production cycle of parts. In addition, many existing industrial fields are biased towards the development of product miniaturization, such as consumer electronics and medical equipment, and the demand for micro components in these fields has increased significantly. The high-precision micro-parts processing requires high cost and technology, because the micro-parts are close to the tolerance of the part size before the surface finish processing. At present, some ...

AI Technical Summary

Problems solved by technology

There have been researches on the market that have tried to integrate the grinding and polishing machine with manipulators or CNC machining centers into an automated system, but this method has the same limitations as traditional contact grinding and polishing, that is, it cannot grind and polish workpieces with fine texture or deep groove features

Moreover, the traditional grinding and polishing process is a material reduction technology, which leads to deviations in the size of the final product.
