Plasma cutting machine can effectively cut all kinds of metals, especially non-ferrous metals, under the action of various working gases. For some metal plates, the plasma cutting machine maintains a fast cutting speed, and the cutting surface is very smooth without obvious thermal deformation.

Since the working gas is mainly a plasma arc medium, it is necessary to remove the

molten metal near the notch during the cutting process.


At present, the penetration ability of CNC plasma cutting machine in China to a certain extent, the main method of metal processing is still manual processing, which not only causes a large amount of waste of resources, but also brings a huge body burden to the relevant personnel.

In recent years, with the continuous development of industrial technology in China, the CNC plasma cutting technology in China has made some progress, but there are still some shortcomings in some links, which need to be further improved.


The air pressure fault of CNC plasma cutting machine is only the working pressure of the machine is too low or too high.


Low pressure. When the air pressure is too low, the injection speed of the ion arc will decrease, the air input will not meet the cutting standard, and the slit will be serrated, which can lead to the increase of the slit and affect the quality of the whole slit.The reason of air pressure is mainly due to insufficient air input of air compressor and low adjustment of control valve pressure.In order to prevent the above situation, it is necessary for the staff to observe the output pressure of the air compressor closely before using the machine, and adjust it accordingly according to the actual situation, so that the working pressure of the machine can meet the requirements. Check the inside of the machine regularly.


High air pressure. If the working pressure of the machine is too high, the arc column will be blown away and the cutting strength of the plasma arc will be reduced. The main reason for high pressure is that the failure of air conditioning or air filter safety valve is unreasonable.To avoid this situation, employees should test the air pressure before the machine runs. If there is a fault during the operation of the machine, the pressure reducing valve should be replaced. The ground wire machine tool and the signal ground wire are connected to the same ground, waiting for public grounding and then grounding.


On the basis of summing up the actual work, this paper summarizes the problems and matters needing attention in the installation and debugging of CNC machine tools, hoping to provide reference for future operators. With the development of machinery industry, the original professional knowledge ability can no longer meet the actual needs, only continuous exploration, continuous learning, scientific and technological innovation road, China's plasma cutting technology is still in the development stage.There is still a big gap compared with developed countries. It is believed that with the continuous development of CNC technology, electronic technology and cutting technology in China, CNC plasma cutting machine will reach a higher level.
