With the increasing domestic steel consumption, the requirements for steel processing technology have also been significantly improved. Processing requirements such as material cutting, welding, bending, etc., are relatively inefficient in the use of some early handheld devices. In addition, the unstable operation of the manual operation of manual and manual equipment on the processing accuracy is also an urgent problem that enterprises need to solve. From the perspective of the industry, in the early domestic mechanical processing, manual cutting, semi-automatic cutting machine cutting and CNC cutting machine cutting for sheet metal cutting. Manual cutting is flexible and convenient, but the quality of manual cutting is poor, the dimensional error is large, the material waste is large, the subsequent processing workload is large, the working conditions are bad, and the production efficiency is low. The profile cutting machine in the semi-automatic cutting machine has a good quality of cutting the workpiece, and it is not suitable for single piece, small batch and large workpiece cutting because of the use of the cutting die. Other types of semi-automatic cutting machines, while reducing the labor intensity of workers, are simple in function and are only suitable for cutting parts of more regular shapes. Compared with manual and semi-automatic cutting methods, CNC cutting can effectively improve the cutting efficiency and cutting quality of the sheet and reduce the labor intensity of the operator. At present, some small and medium-sized enterprises in China even use manual cutting and semi-automatic cutting methods in some large enterprises. At present, the use of steel in China's machinery industry has reached more than 300 million tons, and the cutting amount of steel is very large. With the development of modern machinery industry, the requirements for the work efficiency and product quality of sheet metal cutting processing are also improved. Therefore, the market potential of CNC cutting machines is still very large, and the market prospects are relatively optimistic. From the application situation of various CNC cutting machines, the overall level of the technical level and machine performance of the domestically produced CNC cutting machine has made gratifying progress, gradually catching up with the international advanced level, meeting the needs of users, and further improving the market. Competitiveness. Some CNC plasma cutting products in China have formed their own unique characteristics in many aspects, achieving "automation, multi-function and high reliability". In some respects, the technical performance of the product even exceeds that of foreign products. From the development trend, the CNC flame cutting machine will maintain its basic market in the CNC cutting machine market, the water jet cutting market will increase to a certain extent, and the CNC plasma cutting machine and CNC laser cutting machine will become the mainstream in the plate cutting market. Power, special-shaped CNC cutting equipment, contact and non-contact non-metal special CNC cutting equipment will also have a large space for development, the entire CNC cutting machine market will continue to expand. Improve the production efficiency and cutting quality of CNC cutting machine, reduce the production and use cost, improve the automation level and system stability of the whole machine, and improve the system function to become the direction of its technological development.
