Nowadays, the development of the laser cutting processing industry is very fast, and the emergence of various types of laser cutting machine products has greatly enriched the market demand. Below we will focus on the relevant knowledge about laser cutting machines, which will be of greater help to us in our daily operations.
At present, many consumers are using laser cutting machines. However, when using different cutting heads, the cutting effect is also different. Therefore, we don’t know how to choose the most ideal laser cutting machine to cut the heads. Let the laser cutting machine experts inform us which kind of cutting head to choose to have a better cutting power.
Laser cutting machine experts pointed out that only by selecting intelligent laser EPS foam plastic machinery and equipment can the cutting power be greatly improved. Moreover, laser cutting experts have been constantly developing and improving laser cutting machines. It can better meet the needs of consumers; therefore, the laser cutting machine has very good flexibility, especially the interface between the laser cutting machine and the workpiece and the machine; and the laser cutting machine in the laser cutting machine profession, its variety, standard and shape They are all different, so the price of foam machine is widely used in various occupations, and it is deeply loved by consumers.
The cutting start of the selected laser cutting machine is mainly based on its cutting accuracy, and the flexibility of the laser cutting machine is also very important, because the flexibility is better, its cutting power will be higher, so choose The beginning of the cut is the key; multiple sensors can ensure the cutting quality, even when processing the surface of the coated workpiece; and if you want to have a better cutting power, then the sensor and the beginning of the cut are perfectly connected The advantage of this is that the processing time is greatly reduced and the cutting time is more safe and reliable; however, the non-touch sensor system allows the laser cutting machine to have a very good cutting effect, so it is widely used in various occupations.

In addition, here we have to remind you that the auxiliary gas for the laser cutting machine is mainly used: 1. Laser gas (the gas used in the laser generator to generate laser light) 2. Compressed air (usually used to protect the optical path, there are The manufacturer is also used as a shielding gas) http://plastic-mold.cn/3. Auxiliary gas (that is, the gas sprayed from the cutting nozzle of the cutting machine as the host said). It is necessary to know that different auxiliary gases are used for the laser cutting machine to cut different materials. The thickness of the cutting material is different, the pressure of the auxiliary gas and the required flow rate are different. It is like we are performing related cutting of carbon steel with oxygen, and its purity requirement is generally 99.5% or higher. The main function is to support combustion and blow off the cut melt. The pressure and flow rate are different for each laser cutting machine manufacturer, which is inseparable from the size of the cutting nozzle and the thickness of the cutting material. Generally, the pressure is required to be 0.3-0.8Mpa, and the cutting nozzle is generally 0.02-0.05Mpa. The flow rate is hard to say. For example, when cutting 22mm carbon steel, the flow rate of some manufacturers must reach 10M3/h (including the protective oxygen for double-layer cutting nozzles)
For the processing and cutting of stainless steel, nitrogen is used. The function is to prevent oxidation reaction and blow off the molten material. There are high requirements for the purity of nitrogen (especially stainless steel above 8mm, which generally requires a purity of 99.999%). The requirement is relatively large, generally 1Mpa or more, if you want to cut stainless steel of 12mm or more, or thicker to 25mm, the pressure is higher, 2Mpa or more or higher. The flow rate varies according to the type of cutting nozzle, but they are all very large, such as cutting For 12mm stainless steel, some manufacturers require 150m3/h, while cutting 3mm, as long as the flow rate is less than 50m3/h. In terms of cost, the oxygen used for cutting carbon steel is relatively cheap, and the amount of nitrogen used for cutting non-carbon steel is large. The thicker the stainless steel requires a high amount of nitrogen and purity. The cost is high.
