Engraving of metals

In the application of molds, signs, hardware accessories, advertising boards, car license plates and other products, the traditional corrosion process will not only bring environmental pollution, but also low efficiency. Conventional process applications such as machining, such as metal waste and coolant, can also cause environmental pollution.

Although the efficiency is improved, the accuracy is not high and the acute angle cannot be engraved. Compared with the traditional way of deep metal carving, laser metal deep engraving has the advantages of no pollution, high precision, flexible engraving content, and can meet complex engraving techniques. Common materials for metal deep carving include carbon steel, stainless steel, aluminum, copper, precious metals, etc. Now, Raycus engineers will conduct high-efficiency deep engraving parameters research for different metal materials.

1.1 Crater Analysis The test platform was equipped with a laser1, galvanometer2 and focusing mirror with F  163 mm/ 210 mm = 0:78 for deep engraving experiments. The carving size is 10 mm x 10 mm, and the initial parameters of the carving are set, as shown in table 1. By changing the process parameters such as defocus amount, pulse duration  , speed, and filling pitch, the depth measurement is performed using a deep-draw tester to find the process parameters with the best carving effect.
