Current Situation Of Cutting Machines

1. After decades of development, CNC cutting machines have made significant progress in both cutting energy and CNC control systems. Cutting energy has evolved from a single flame energy source to multiple energy sources (flame, plasma, laser, high-pressure water jet) for cutting; The control system of CNC cutting machines has evolved from simple functions, complex programming and input methods, and low automation to a fully functional, intelligent, graphical, and networked control method; The driving system has also evolved from stepper drive and analog servo drive to today's fully digital servo drive;
The main varieties of CNC cutting machines include the following:
CNC flame cutting machine
CNC plasma cutting machine
CNC laser cutting machine
CNC high-pressure water jet cutting machine
Other specialized special cutting equipment (such as CNC pipe cutting machines, CNC profile cutting machines, and other non-metallic special cutting equipment)
2. Characteristics and application of various types of CNC cutting machines
CNC flame cutting machine has the ability to cut thick carbon steel with low cutting cost, but it has large cutting deformation, low cutting accuracy, low cutting speed, long cutting preheating time and perforation time, making it difficult to adapt to the needs of fully automated operations. Its application is mainly limited to the cutting of carbon steel and large thickness plates, and it will gradually be replaced by plasma cutting in the cutting of medium and thin carbon steel plates.
CNC plasma cutting machine, with a wide cutting field, can cut all metal plates, with fast cutting speed and high efficiency, and a cutting speed of over 10m/min. Plasma underwater cutting can eliminate the noise, dust, harmful gases, and arc pollution generated during cutting, effectively improving 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, expanding the cutting range of CNC plasma cutting machines.
CNC laser cutting machine has the characteristics of fast cutting speed and high accuracy. Laser cutting machines are expensive and expensive, and are only suitable for thin plate cutting with high precision requirements,
CNC high-pressure water jet cutting machine is suitable for cutting any material (metal, non-metal, composite material), with high cutting accuracy, no thermal deformation, and an environmentally friendly cutting method. Its drawbacks include slow cutting speed, low efficiency, and high cutting costs.
Other CNC cutting machines: including CNC pipe cutting machines, CNC steel cutting machines, CNC groove cutting machines, CNC woodworking cutting machines. These specialized cutting equipment are mainly used for CNC cutting of various specialized profiles, and there are not many manufacturers in the market.
