With the development of modern machinery processing industry, the requirements for the quality and precision of cutting are continuously improved, and the requirements for improving production efficiency, reducing production cost, and having high 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. Cutting machines are divided into flame cutting machines, plasma cutting machines, laser cutting machines, water cutting and the like. The laser cutting machine is the fastest, the cutting precision is the highest, and the cutting thickness is generally small. The plasma cutting machine also cuts quickly, and the cutting surface has a certain slope. The flame cutter is designed for carbon steel with a large thickness. The laser cutting machine is the fastest, the cutting precision is the highest, and the cutting thickness is generally small.
