Currently, CNC cutting machines widely used in the market mainly use flame cutting and plasma cutting for thermal cutting. The use cost of these two types of cutting methods is one of the concerns of many enterprise users and is used from the market. From the perspective of whether it is flame cutting or plasma cutting, a certain number of companies are adopting it. The China Cutter Trading Network believes that the cutting method should be selected based on the company's own situation. The following two cutting methods and some The cost of other cutting methods is briefly introduced and we hope to give you a little reference.
1, fine plasma cutting precision plasma cutting machine cutting precision up to the lower limit of laser cutting, cutting surface quality is similar, but the cutting cost is much lower than the laser cutting, about its 1/3, the maximum cutting thickness of up to 12mm, so with fine plasma Cutting machine to replace the expensive laser cutting machine, is conducive to the most economical way to use a larger amount of medium and thin high-speed precision cutting.
In addition, CNC plasma cutting and automatic nesting programming software can improve the material utilization rate of 5% to 10%, and annual cutting of 20 million tons, then the steel can save 100 to 200 million tons, worth billions of dollars. Therefore, the development trend of replacing the flame cutting machine and the laser cutting machine with a numerical control plasma cutting machine has appeared in industrialized countries. Therefore, research and promotion of numerical control plasma cutting technology is of great significance.
2, flame cutting machine flame cutting has a large cutting deformation, can not meet the needs of high-precision cutting, and the cutting speed is low, need to be preheated before cutting, take time, it is difficult to adapt to the needs of unmanned operation.
3, plasma cutting machine Plasma cutting has a wide range of cutting, can cut all metal plates and many non-metallic materials, the maximum cutting speed of up to 10m/min, is 10 times the flame cutting. Cutting underwater can eliminate the noise, dust, harmful gas and arc generated during cutting, which is conducive to the protection of the environment and meet the environmental protection requirements of the 21st century. At present, with the maturity of high-power plasma cutting technology, the cutting thickness has reached 130mm.
4. Water jet cutting The high-power plasma cutting with water jet technology has made the cutting quality close to the lower limit of laser cutting (±0.2mm). Since laser cutting machines are expensive, they are currently only suitable for thin-plate cutting (usually thick plate punching takes a long time).
