Gantry CNC plasma cutting machine, as an important application category of thermal cutting, has good performance in terms of cutting efficiency and cutting accuracy. However, judging from the current operating conditions of most domestic production companies, there are very few companies that can truly achieve high-quality and efficient operations. So what is the operating level of the gantry CNC plasma cutting machine, which is mainly reflected in the following aspects:

The height and stability of the cutting nozzle: The parts cut by the gantry CNC cutting machine can be directly welded and used without mechanical processing. However, the gantry CNC plasma cutting machine uses plasma arc cutting, which is compared to oxygen cutting. There are also some defects, mainly reflected in the large inclination of the cutting surface and the smoothness is not as good as oxygen cutting. The main criteria for evaluating the quality of CNC plasma cutting are: the inclination of the cutting surface, the cutting depth of the cutting seam, the amount of slag, etc.

Matching of cutting speed and working air pressure: Gantry CNC plasma cutting machine is an advanced electromechanical integrated metal plate cutting equipment. It has been widely used in shipbuilding, machinery manufacturing and other industries. There are many factors that affect the cutting quality of the gantry CNC plasma cutting machine. In addition to the design parameters of the cutting machine, it is also related to the operation control and cutting technology.

For a high-quality cutting surface, its inclination should be below 30, the cutting depth should be below 0.15 mm, and there should be less slag and easy removal. When the height of the cutting nozzle from the steel plate is controlled by the arc pressure regulator, the dynamic positioning accuracy can reach /-0.013 liters, thus ensuring that the height of the cutting nozzle and the steel plate remains unchanged, so the inclination of the cutting surface is small and uniform, and the finish is good . When manually adjusting the height of the cutting nozzle from the steel plate, the steel plate to be cut should be leveled as much as possible to reduce the number of torch adjustments and ensure the stability of the torch cutting process.

If manual adjustment is used and the height of the cutting nozzle from the steel plate is controlled at 6-8 mm, a series of cutting tests can prove that the cutting quality is significantly improved. In addition, in order to improve the cutting quality, we conducted a comprehensive cutting test on it, analyzed and organized the test data, and obtained some great working parameters of the gantry CNC plasma cutting machine. The introduction is as follows: CNC plasma cutting machine can cut various workpieces with complex shapes. It has the advantages of fast cutting speed, high efficiency, good cutting surface quality, accurate cutting size, and small thermal deformation of the workpiece.
