The use of stainless steel laser cutting machine requires special attention to quality control
Stainless steel laser cutting machine is a classification of metal laser cutting machine. It is specially made for stainless steel. It uses the energy released when the laser beam irradiates the surface of the steel plate to melt and evaporate the stainless steel.

The mechanism of stainless steel laser cutting machine
The stainless steel laser cutting machine occupies a larger proportion in industrial production. The main area of stainless steel and low-carbon copper is the difference in composition, and the cutting mechanism is also different. Stainless steel contains 1% to 20% chromium deposits tend to destroy the oxidation process.
During cutting, the iron in the stainless steel will all react exothermicly with oxygen. The oxidation of chromium has the characteristic of preventing oxygen from entering the molten material, and reduces the amount of oxygen entering the molten layer. The molten layer is oxidized incompletely and the reaction is reduced, which makes the cutting speed. reduce. Compared with low carbon steel, stainless steel cutting requires higher laser power and oxygen pressure. Although stainless steel cutting achieves a more satisfactory cutting effect, it is difficult to obtain a completely slag-free kerf. Using inert gas as auxiliary gas to cut stainless steel can obtain non-oxidized trimming, which is directly used for welding, but its cutting speed is about 10% lower than that of oxygen as auxiliary gas.

Quality control of stainless steel laser cutting machine
The cost of stainless steel laser cutting is higher than that of wire cutting. The accuracy is not as good as wire cutting, but the speed is twice that of wire cutting, which can realize mass production, and after cutting, it can process non-metallic materials to realize intelligent processing. One machine replaces multiple stages and becomes the core of processing equipment. It can be seen that stainless steel laser cutting is a fast and effective processing method, but it is particularly important to control the cutting quality.
When laser cutting mirror stainless steel, in order to prevent serious burns to the plate, a laser film is required! Although it is protected by a film, there is still a little burn on the edge. At this time, it is necessary to strictly control the laser cutting process parameters during the processing to maintain the good corrosion resistance of such materials. The most important process parameters that affect the quality of stainless steel cutting are cutting speed, laser power, oxygen pressure and focus.
In addition, the surface smoothness of stainless steel products in many industries is relatively high. So, what should I do if burrs occur in the stainless steel laser cutting laser cutting machine? Burrs in stainless steel laser cutting are generally caused by the cutting nozzle of the cutting head. This factor should be investigated first. If replacing the cutting nozzle can not solve it, check whether the movement of the laser cutting machine guide rail is stable.
