The role of air as auxiliary gas in laser cutting machine cutting

Since the 1970s, laser technology has gradually entered the field of industrial cutting. Until today, laser cutting equipment has been widely used in enterprises. However, due to the popularity of laser cutting equipment, product price competition between enterprises has become more and more fierce. This has caused the profitability of laser cutting equipment to decline in the enterprise.

At present, the entire processing and manufacturing industry needs to be transformed and upgraded. Enterprises need to focus their funds on Laser Cutting Machine brand process improvement, efficiency improvement, and increased R&D investment. More value-added production Under the background of the link, how to reduce the cost of laser cutting equipment is very urgent. This article will focus on the use of air as an auxiliary gas to reduce cutting costs in the laser cutting process.

Let's take a look at the process of laser cutting: after the laser generated by the oscillator passes through the lens, it is concentrated at a point to form a very small spot. By precisely controlling the distance between the lens and the plate, the laser spot is stable in the material thickness direction At a certain position, due to the converging effect of the lens, the laser energy with a very high power density is gathered at the spot, and the power density can usually reach 106-109W/cm2. After the material absorbs the spot energy, it melts instantly. The liquid blows off the material to complete the cutting process.
