In the process of mechanical processing, plate cutting is commonly used in manual cutting, semi-automatic cutting machine cutting and CNC cutting machine cutting. The manual cutting is flexible and convenient, but the manual cutting quality is poor, the size error is large, the material waste is large, the follow-up processing workload is large, at the same time, the labor conditions are bad, the production efficiency is low. Semi-automatic cutting machine in the copy cutting machine, cutting workpiece quality is better, because of its use of cutting die, is not suitable for single, small batch and large pieces of cutting. Other types of semi-automatic cutting machine although reduce the labor intensity of workers, but its function is simple, only suitable for some more regular shape parts cutting. CNC cutting compared with manual and semi-automatic cutting, can effectively improve the efficiency of plate cutting, cutting quality, reduce the labor intensity of the operator. In some small and medium-sized enterprises in our country even in some large enterprises using manual cutting and semi-automatic cutting way is more common. The amount of steel used in Chinese mechanical industry has reached 300 million tons above, the cutting amount of steel is very large; With the development of modern machinery industry, the efficiency of plate cutting processing and product quality requirements are also improved. Therefore, the market potential of CNC cutting machine is still very large, the market prospect is more optimistic. 1, after decades of development, CNC cutting machine in cutting energy and CNC control system has made great progress in two aspects, cutting energy has developed from a single flame energy cutting into a variety of energy (flame, plasma, laser, high pressure water jet) cutting; The control system of CNC cutting machine has been developed from the original simple function, complex programming and input mode, the degree of automation is not high to have perfect function, intelligent, graphical, networked control mode; Drive system from the step drive, analog servo drive to today's full digital servo drive; The main varieties of CNC cutting machine include the following: CNC flame cutting machine CNC laser cutting machine CNC CNC plasma cutting machine for other special high pressure water jet cutting machine cutting equipment (such as CNC pipe cutting machine, CNC profile cutting machine, and other nonmetal special equipment, such as cutting,) 2, various types of CNC cutting machine characteristics and the applications of the CNC flame cutting machine, cutting with large thickness carbon steel cutting ability, Cutting cost is low, but there is a large cutting deformation, cutting accuracy is not high, and the cutting speed is low, cutting preheating time, perforation time is long, it is difficult to adapt to the needs of full automation operation. Its application is mainly limited to carbon steel, large thickness plate cutting, in the medium and thin carbon steel plate cutting will gradually be replaced by plasma cutting. CNC plasma cutting machine, plasma cutting with wide cutting field, can cut all metal sheet, cutting speed, high efficiency, cutting speed up to 10m/min above. Plasma in underwater cutting can eliminate the noise, dust, harmful gas and arc light pollution generated during cutting, and effectively improve the working environment. The use of fine plasma cutting has made the cutting quality close to the laser cutting level, with the maturity of high-power plasma cutting technology, cutting thickness has exceeded 100mm, broaden the cutting range of CNC plasma cutting machine. CNC laser cutting machine, cutting speed, high precision, laser cutting machine is expensive, the high cost of cutting, only suitable for sheet cutting, requiring high precision, CNC high pressure water jet cutting machine, suitable for cutting any material (metal, nonmetal and composite materials), high cutting precision, does not produce hot deformation, cutting way of environmental protection. Its disadvantage lies in the slow cutting speed, low efficiency, high cutting cost. Other numerical control cutting machine: including numerical control pipe cutting machine, numerical control steel cutting machine, numerical control groove cutting machine, numerical control woodworking cutting machine, these special cutting equipment is mainly used in a variety of special profiles to numerical control cutting, the market manufacturers are not many. With the development of modern machinery processing industry, the quality of cutting, precision requirements are constantly improving, to improve production efficiency, reduce production costs, with high intelligent automatic cutting function requirements are also improving. The development of CNC cutting machine must meet the requirements of the development of modern mechanical processing industry.
