CNC plasma cutting machineThe stability of the plasma power supply is an important factor affecting the cutting quality. If the ds is unstable after the plasma is powered, it may cause defects such as uneven cutting, tumor accumulation during cutting, etc., and it will also cause the service life of related parts of the control system to be reduced, and frequent replacement of nozzles and electrodes.

The cutting accuracy, cutting saw, cutting speed, plate height and other factors of the CNC plasma cutting machine will affect the cutting quality. Although there are many influencing factors, in general, the main factor is the choice of plasma cutting power supply. Therefore, in the use of CNC plasma cutting machine, in order to high-quality fast cutting, it is necessary to understand and master the cutting process parameters of the cutting machine. Only in this way can the advantages of plasma cutting equipment be fully utilized to ensure the high quality of the cutting workpiece. In the cutting process of the CNC plasma cutting machine, the adjustment of the cutting current of the plasma power supply is very important, and its quality is directly related to the cutting thickness and cutting speed.

When the cutting current of the plasma CNC cutting machine increases, the plasma arc energy increases, the cutting ability increases, and the cutting speed increases; instead, it becomes smaller. The cutting current of the CNC plasma cutting machine increases, the diameter of the plasma arc increases, and the arc becomes thicker and the incision becomes wider; if the cutting material is thicker, the nozzle is small, and the cutting current of the plasma CNC cutting machine is too large, the thermal load of the nozzle will Increase, the nozzle is damaged prematurely, the cutting quality is naturally poor, and the serious damage or even normal cutting cannot be performed. Therefore, before cutting, the cutting current and the corresponding nozzle should be correctly selected according to the thickness of the material to ensure the cutting quality.

　CNC plasma cutting machineMaintenance:

1. Assemble the torch correctly. CNC plasma cutting machine manufacturers believe that the torch should be installed correctly and carefully, to ensure that all parts are well matched, and to ensure the circulation of gas and cooling air. Place all installed components on a clean flannel to avoid dust sticking to the components. Add proper amount of lubricating oil to the O-ring to make the O-ring shine. Do not add more cutters for maintenance.

2. Consumables should be replaced in time before they are completely damaged. CNC plasma cutting machine manufacturers believe that the wearing parts should not be replaced after they are completely damaged, because severely worn electrodes, nozzles and swirl rings will produce uncontrollable plasma arcs, which will easily cause serious damage to the torch. Therefore, when the cutting quality is found to be reduced, the wearing parts should be checked in time.

3. Clean the connecting thread of the torch. When replacing wearing parts or performing routine maintenance and inspection, the internal and external threads of the cutting torch must be kept clean. If necessary, the connecting threads should be cleaned or repaired.

4. CleaningCNC plasma cutting machineThe contact surface of the electrode and the nozzle. CNC plasma cutting machine manufacturers believe that in many cutting torches, the contact surface between the nozzle and the electrode is a charged contact surface. If there is dirt on these contact surfaces, the torch will not work properly, so use hydrogen peroxide cleaning agent to clean.
