1. After decades of development, CNC cutting machines have made considerable progress in cutting energy and CNC control systems. Cutting energy has evolved from a single flame energy cutting to multiple energy sources (flame, plasma, laser, high-pressure water). Jet) cutting method; the control system of the CNC cutting machine has evolved from simple functions, complex programming and input methods, and low automation to a fully functional, intelligent, graphical, and networked control method; the drive system has also changed from Stepper drive, analog servo drive to today's all-digital servo drive;
2. The characteristics and application of various types of CNC cutting machines
The CNC flame cutting machine has the ability to cut large-thick carbon steel, and the cutting cost is low, but there are large cutting deformations, low cutting accuracy, low cutting speed, long cutting preheating time, long piercing time, and it is difficult to adapt to full automation Operational needs. Its application is mainly limited to the cutting of carbon steel and large thickness plates, and will gradually be replaced by plasma cutting in the cutting of medium and thin carbon steel plates.
CNC plasma cutting machine, plasma cutting has a wide cutting area, which can cut all metal plates, with fast cutting speed and high efficiency, and the cutting speed can reach more than 10m/min. Plasma cutting under water can eliminate the noise, dust, harmful gas and arc pollution generated during cutting, and effectively improve the working environment. The use of fine plasma cutting has made the cutting quality close to the level of laser cutting. With the maturity of high-power plasma cutting technology, the cutting thickness has exceeded 100mm, which has broadened the cutting range of CNC plasma cutting machines.
The CNC laser cutting machine has the characteristics of fast cutting speed and high precision. The laser cutting machine is expensive and the cutting cost is high. It is only suitable for thin plate cutting and high precision occasions.
The CNC high-pressure water jet cutting machine is suitable for cutting any material (metal, non-metal, composite material), with high cutting precision, no thermal deformation, and an environmentally friendly cutting method. Its disadvantages are slow cutting speed, low efficiency and high cutting cost.
Other CNC cutting machines: including CNC pipe cutting machines, CNC section steel cutting machines, CNC bevel cutting machines, CNC woodworking cutting machines, these special cutting equipment are mainly used for CNC cutting of various special profiles, and there are not many manufacturers in the market.
