The frame of the CNC cutting machine is very important, therefore, if the frame is improperly set, the metal laser cutting machine is prone to unstable operating conditions, and the damage frequency of the metal laser cutting machine will be greatly increased. Therefore, it is very important to stabilize the structure of the metal laser cutting machine. The life of the electrode is greatly reduced; The air pressure is too low, and the accurate air pressure of the plasma and the service life of the consumables are very important.

If the pressure is too high. The life of the nozzle will be affected. As far as possible to clean the cutting torch and waste parts any dirt on the cutting torch and waste parts will affect the function of the plasma system. When changing the cost parts, place them on a clean flannelette. Clean electrode contact surface and nozzle with hydrogen peroxide cleaning agent. The grasp of preheating time needs to pay attention to many factors, such as cutting plate thickness, cutting gas, cutting speed, fire point location and other factors.

Synthesize many factors to adjust the length of preheating time. CNC plasma cutting machine is mainly for the workpiece cutting machinery, CNC plasma cutting machine workflow mainly includes the preparation before cutting, cutting and cutting three aspects. It is necessary to understand the construction principle of the cutting machine, familiar with its mechanical transmission system, electrical system, gas system, water system, familiar with the functions of various switches and knobs, pull the control power supply opening, start the "test high frequency" switch.

Look at the spark between the electrode and the inner hole wall of the nozzle from the nozzle end, if there is more than 2/3 of the spark around the electrode, it means that the electrode is in good shape, and then turn off the high frequency. Nuclear industry, shipbuilding, steel structure and other industries! Because plasma cutting can be used to cut stainless steel, aluminum, copper, titanium, ordinary carbon steel and other non-ferrous metals.

In some specific areas, oxyacetylene cutting can be substituted. The cutting efficiency is greatly improved. In terms of cutting effect, the cutting error of medium and thin sheets can be controlled within (+0.5mm). The cutting surface quality of fine plasma cutting technology is close to laser cutting, but the cost is much lower than laser cutting.
