In the process of mechanical processing, the common methods of plate cutting include manual cutting, semi-automatic cutting machine cutting and CNC cutting machine cutting. Manual cutting is flexible and convenient, but manual cutting has poor quality, large dimensional errors, large material waste, and heavy follow-up processing workload. At the same time, the working conditions are harsh and the production efficiency is low. Among the particular semi-automatic cutting machines, the profiling cutting machine has good quality of cutting workpieces. As it uses a cutting expire, it is not suited to single-piece, small-batch and large-scale reducing. Although other types associated with semi-automatic cutting machines minimize the labor intensity regarding workers, their functions are simple and therefore are only suitable for cutting even more regular-shaped parts. Compared with manual and semi-automatic cutting methods, CNC cutting can effectively improve the efficiency and quality of plate cutting, and reduce the labor intensity of operators. Some small and medium-sized enterprises in our country even use manual cutting and semi-automatic cutting methods in some large enterprises.
The amount of steel used in my country's machinery industry has reached more than 300 million tons, and the amount of steel cut is very large; with the development of the modern machinery industry, the requirements for work efficiency and product quality of plate cutting have also increased. Therefore, the market potential of CNC cutting machines is still very large, and the market prospect is relatively optimistic.
CNC flame cutting machine has the ability to cut large thickness carbon steel, and the cutting cost is low, but it has large cutting deformation, low cutting precision, low cutting speed, long cutting preheating time and 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 it 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 field, can cut all metal plates, fast cutting speed, high efficiency, cutting speed can reach more than 10m/min. Plasma cutting under water can eliminate noise generated during cutting, dust, harmful gas and arc light pollution, 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 broadens the cutting range of CNC plasma cutting machines.
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 occasions 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 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 in CNC cutting of various special profiles, and there are not many manufacturers in the market.
