Description

technical field [0001] The invention relates to the technical field of laser polishing, in particular to a laser polishing device and a laser polishing method. Background technique [0002] As a new laser processing application technology, laser polishing technology uses a focused laser beam spot to act on the rough original metal surface, causing the melting and evaporation of a raised thin layer on the surface of the metal material, and the molten material is on the surface of the material itself It flows under the action of tension and gravity, fills the depressions on the metal surface and solidifies, and finally obtains the ideal surface of the polished material. [0003] Titanium alloy has high strength and low density, good mechanical properties, good toughness and corrosion resistance. It is mainly used in aerospace and other fields. It is one of the most important alloy materials in the 21st century. Laser polishing currently on the market cannot be multi-axis Link...

Problems solved by technology

[0003] Titanium alloy has high strength and low density, good mechanical properties, good toughness and corrosion resistance. It is mainly used in aerospace and other fields. It is one of the most important alloy materials in the 21st century. Laser polishing currently on the market cannot be multi-axis Linkage, for example, the laser emits laser light, the laser galvanometer lifts, and the rotation device rotates. These three cannot be performed at the same time; and there are still many laser devices that use manual lifting and rotation, which has low precision and sensitivity.
