Foreign countries have used CNC plasma cutting machine to cut metal materials as early as 40 years ago. my country is 30 years behind foreign companies. However, with the reform and opening up and economic development, my country's CNC fine plasma cutting machine technology has become increasingly mature, and the research and development level has been continuously improved. High-tech products have been continuously developed and successfully put on the market, making my country's domestic equipment a strong competitor to imported equipment, especially in the shipbuilding industry.

The main types of CNC plasma cutting machines are: conventional plasma arc cutting, dual-gas plasma arc cutting, water jet plasma arc cutting, long-life oxygen plasma arc cutting, and CNC fine plasma cutting machines.

Now many shipbuilding industries want to achieve precision shipbuilding and efficient shipbuilding during the shipbuilding process, so the cutting requirements are becoming more and more stringent. The successful development of CNC fine plasma cutting machines has made the goal pursued by the shipbuilding industry no longer a dream.

In the past, many industries would choose CNC laser cutting machines for high-precision cutting because it has the characteristics of fast cutting speed, high precision, good cutting quality and high work efficiency. However, domestic laser cutting machines are relatively backward, and many companies choose foreign products with high costs, which restricts the development of domestic laser cutting machines; plus it has many shortcomings in cutting medium and thick plates. In the future, to solve these problems, while effectively ensuring work efficiency and cutting quality, it is also necessary to reduce production costs, which promotes the development of CNC fine plasma cutting machines.

The cutting arc current density of CNC fine plasma cutting machines is high, and the introduction of rotating magnetic field technology has good arc stability, which makes the cutting precision very high. Fine plasma cutting reduces the operating cost while cutting efficiently and accurately. Its cost is only one-third of laser cutting, so it has won the favor of many industries, especially the shipbuilding industry.

The development of CNC fine plasma cutting technology not only solves the problems of poor work efficiency, low material utilization, and unstable quality in my country's thermal cutting industry, but also drives the development of other related fields in my country.
