Cutting machine is divided into flame cutting machine, plasma cutting machine, laser cutting machine, water cutting and so on. The laser cutting machine is the fastest, the highest cutting accuracy, and the cutting thickness is generally small. Plasma cutting machine cutting speed is also very fast, the cutting surface has a certain degree of slope. Flame cutting machines are designed for thicker carbon steel materials. 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 a highly intelligent automatic cutting function are also increasing. The development of CNC cutting machines must adapt to the requirements of the development of modern machinery processing industry.
