With the development of modern machinery processing industry, the requirements for the quality and precision of cutting have been continuously improved, and the requirements for improving production efficiency, reducing production costs, and having high-efficiency automatic cutting functions are also increasing. As a part of the cutting machine industry, the products we provide will be the most modern and technological. Welcome everyone to discuss cooperation. Details:/
Chinese cutting machine trading network, engaged in CNC cutting machine for many years, now to give you an analysis of the flame cutting machine, plasma cutting machine, laser cutting machine, the three cutting in the market requirements and market status, technical and economic comparison:
Due to the effects of air pressure, cutting tip height, and preheating time, flame cutting has a large scale of deformation of the entire cutting material, which cannot meet the need for high-precision cutting, and the cutting speed is low. At the same time, it takes time to warm up before cutting. It is difficult to adapt to the needs of unmanned operations. Plasma cutting has the advantages of high cutting speed and wide range. It is suitable for cutting low-thickness metal plates and various non-metallic materials. The maximum cutting speed can reach 10m/min, which is 10 times that of flame cutting. Cutting underwater can eliminate the noise generated during cutting, dust, harmful gases and arcs, which is conducive to environmental protection requirements. With the maturity of high-power plasma cutting technology, the cutting thickness can reach 130mm. High-power plasma cutting with water jet technology has made the cutting quality close to the lower limit of precision of laser cutting (±0.2mm). Because the laser cutting machine is expensive, and currently only suitable for thin plate cutting (usually thick plate punching time is long), and fine plasma cutting machine cutting precision can reach the lower limit of laser cutting, the cutting surface quality is similar, but the cutting cost is much lower than the laser The cutting is about 1/3 of the way, and the maximum cutting thickness can reach 12mm. Therefore, replacing the expensive laser cutting machine with a fine plasma cutting machine is beneficial to the high-speed fine cutting of medium and thin plates with a large amount in the most economical way. . In addition, CNC plasma cutting and automatic nesting programming software can improve the material utilization rate of 5% to 10%, annual cutting 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.
China's CNC flame cutting technology started in the mid-1980s, and the CNC plasma cutting machine is even later. Most CNC plasma cutting machines are based on economical machine tools (MCU as the core and stepper motors as driving elements). There were once more than 50 manufacturers who had once engaged in the manufacture of CNC cutting machines in China, and their power was dispersed. Many of the manufacturers' predecessors were welding and cutting tools factories, and their technical foundation was poor. Throughout the 1980s, domestic companies were unable to compete with foreign companies in terms of product structure or production scale. After entering the 1990s, some domestic companies aimed at the world advanced level and continuously developed new products for CNC cutting machines. Moreover, the main technical indicators of some products have reached the advanced level of similar foreign equipment, and at the same time with the regulation and control of the market economy, The number of domestic manufacturers of CNC cutting machines has been adjusted to 20, but the overall R&D production capacity has been significantly improved compared to the past. Especially in recent years, the domestic CNC cutting industry has invested a lot of funds and R&D forces to achieve breakthroughs in related fields such as steel pipe cutting and intersecting wire cutting. As a landmark technological achievement of the CNC cutting industry, intersecting wire cutting will broaden the range of cutting of the original material and achieve the possibility of bevel cutting of the pipe material. And earlier, similar CNC systems were only proprietary to foreign manufacturers. A multi-axis linkage cutting machine costs up to one million yuan.
