1. Why do laser cutting machines use air compressors?

Laser cutting machine is already a more common machining equipment in the metal processing industry, many people in the purchase of laser cutting machine, do not know that the operation of laser cutting machine actually needs to rely on a lot of auxiliary equipment to complete the processing, air compressor is one of its auxiliary equipment, because many companies do not understand the role of air compressor, do not pay attention to, It often has a great impact on the quality of the products cut out by the laser cutting machine.

Since the cost of nitrogen and oxygen is higher than that of compressed air, and the price of nitrogen and oxygen is rising year by year, the use of air as a cutting auxiliary gas can greatly reduce the production cost by about half. In addition, since the air itself contains about 20% oxygen, it can make up for the shortage of oxygen and nitrogen to a certain extent. The use of compressed air instead of nitrogen cutting is very economical and practical, and the cost of gas saved in a year is enough to buy 3 high-quality 레이저 커팅 특수 공기 압축기. Therefore, the use of compressed air as an auxiliary gas cutting is becoming more and more common, which has also led to the rise of the laser cutting air compressor market.

2. The impact of compressed air quality on laser cutting quality

The quality of compressed air has a very direct impact on the quality of laser cutting. Compressed air contains water mist and oil, if not treated clean, high pressure spray to the laser cutting head protection mirror, it will seriously affect the transmission of the laser beam, so that the focus is dispersed, resulting in product cut through, resulting in waste products. If it is a super power laser cutting machine, as long as the surface of the protection mirror or nozzle is glued to a little tiny oil film or water mist, it may also cause high-energy laser emission to burn out the laser head. Because the price of the laser head of the ultra-high power laser cutting machine (above 12000W) is more than 20,000, and most air compressor providers can not handle the oil and water in the compressed air well, most users of the ultra-high power laser cutting machine are not willing to take the risk of using compressed air as an auxiliary gas.

3. Characteristics of laser cutting special air compressor

Screw air compressor for laser cutting can cope with the cutting requirements of various materials and complex shapes, in addition to the need to provide high energy lasers, auxiliary gas is the material to complete the cutting. The auxiliary gases used for laser cutting are mainly oxygen, nitrogen and compressed air. Its main function is to cool the material to prevent hardening, that is, to be heat treated. The second is to blow off the molten metal slag with pressure gas, prevent dust from blocking the laser nozzle, protect and extend its service life.
