While CNC plasma cutting machines were already being used to cut metal materials abroad 40 years ago, my country lagged behind foreign companies by 30 years. However, with reform and opening up and economic development, my country's CNC precision plasma cutting machine technology has matured significantly, and its research and development level has continuously improved. High-tech products are constantly being developed and successfully launched into the market, making domestically produced equipment a strong competitor to imported equipment, especially in the shipbuilding industry.

The main types of CNC plasma cutting machines include: conventional plasma arc cutting, dual-gas plasma arc cutting, waterjet plasma arc cutting, long-life oxygen plasma arc cutting, and CNC precision plasma cutting machines.

Many shipbuilding companies now aim for precision shipbuilding and construction, thus placing increasingly stringent demands on cutting techniques. The successful development of CNC precision plasma cutting machines has made this goal a reality for the shipbuilding industry.

Previously, many industries opted for CNC laser cutting machines for high-precision cutting due to their advantages such as high cutting speed, high precision, good cutting quality, and high work efficiency. However, the development of domestic laser cutting machines lagged behind, leading many companies to choose imported products, which resulted in higher costs and hindered the development of domestic laser cutting machines. Furthermore, CNC laser cutting machines had several drawbacks when cutting medium-thick plates. Solving these problems, while effectively ensuring work efficiency and cutting quality, while reducing production costs, has spurred the development of CNC precision plasma cutting machines.

CNC precision plasma cutting machines feature high arc current density and, with the introduction of rotating magnetic field technology, excellent arc stability, resulting in extremely high cutting precision. Precision plasma cutting reduces operating costs while achieving high precision, costing only one-third that of laser cutting. Therefore, it has gained favor in many industries, especially shipbuilding.

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