Comparison between CNC plasma cutting machine and CNC gas cutting machine

CNC gas cutting machine is suitable for cutting large thickness carbon steel and cutting costs are low. But its cutting deformation is large, cutting accuracy is not high, and cutting speed is low, cutting preheating time, long time perforation, it is difficult to adapt to the needs of automatic operation. Its application is mainly limited to carbon steel, large thickness plate cutting, in the medium and thin carbon steel plate cutting will be gradually replaced by CNC plasma cutting machine.

CNC plasma cutting machine, plasma cutting field wide, can cut all metal sheets, cutting speed, high efficiency, cutting speed can reach more than 10 m / min. Plasma cutting machine can eliminate the noise, dust, harmful gas and arc pollution when cutting underwater, and effectively improve the working environment. With the development of high power plasma cutting technology, the cutting thickness has exceeded 100 mm, which widens the cutting range of NC plasma cutting machine.

From the actual operation, not only plasma cutting, including flame cutting, but also a variety of cutting methods, speed will affect the quality of cutting seam, but the specific relationship also needs to involve many factors, such as the thickness of cutting materials, cutting height and cutting current size (such as the use of flame cutting still need to be). Consider the problem of warm-up time.

CNC plasma cutting machine has the characteristics of fast cutting speed and small cutting seam in the cutting process, but many users and enterprises in the actual operation process often appear a variety of problems, resulting in the actual cutting speed is limited, cutting seam is too large, cutting surface irregularity and other phenomena, which in our after-sales department contacted in many cases are It can be concluded that the selection and use of consumables for CNC plasma cutting machine is unreasonable. It is necessary to pay attention to the quality of electrode cutting nozzle when purchasing the electrode cutting nozzle used in CNC plasma cutting machine. Because the nozzle loss is more frequent when using plasma cutting than flame cutting, the quality of the nozzle purchased by many users is not good, which aggravates the nozzle loss in the process of using. This point needs special attention and can not be simply saved. Cost and choose poor quality electrode cutting nozzle, under normal circumstances, a set of electrode cutting nozzle service life is 3-4 hours, but there are nearly half of the end-user enterprises are not to achieve this long-term use, the elimination of CNC plasma cutting machine mechanical failure and other factors, user enterprises in operation is not correct. Setting the relevant parameters of CNC plasma cutting machine will also affect the actual cutting effect.
