correct useCNC plasma cutting machineWhen performing high-quality high-speed cutting, it is necessary to deeply understand and master the parameters of the cutting process. Only in this case, the CNC plasma cutting machine can be effective, and its cutting workpiece can also get good results. The CNC cutting machine adjusts the parameters of the plasma power supply to cut off the current when cutting the workpiece, for the majority of users to learn. So, let's take a look at the performance of CNC plasma cutting machine equipment and cutting current settings.

When cutting a workpiece with a CNC plasma cutting machine, the adjustment of the cut-off current of the mechanical plasma power supply is very important. It is an important cut-off process parameter that determines the thickness and speed of the direct cut-off, that is, the cut-off ability. The influence is directly manifested in the selection of the cutting current of the CNC plasma cutting machine:

1. The cutting current of the CNC plasma cutting machine increases, the plasma arc energy increases, the cutting ability increases, and the cutting speed increases;

2. 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;

3. If the cutting current is too large, the thermal load of the nozzle will increase, the nozzle will be damaged quickly, and the cutting quality will naturally decrease, even if it cannot be cut normally. Before cutting, please select the cutting current and the corresponding nozzle according to the thickness of the material.

　　CNC plasma cutting machineCutting current: Current is an important parameter of CNC plasma cutting machine, which directly determines the cutting capacity, speed and quality of CNC cutting machine. Main performance:

1. The cutting current increases, the cutting ability increases, and the cutting speed increases; at the same time, the arc diameter increases and the incision becomes wider;

2. It is necessary to increase the replacement frequency of consumables to avoid excessive cutting current, increased nozzle heating, increased load, and accelerated nozzle damage, which will affect the cutting quality.

　　CNC plasma cutting machineCutting speed: according to the material thickness, material, melting point, thermal conductivity and melting tension and other factors, the cutting speed should be adjusted accordingly.

Main performance:

1. When the cutting speed is low, the heating time of the plate with large cutting gap, large cutting groove angle and thickness less than 20mm is too long and easy to deform.

2. If the cutting speed is too low, the plasma arc will transfer more heat around the cutting path, which will widen the cutting surface, and the molten metal liquid will be blown near the cutting surface by the excess cutting gas, which will fully heat and condense to form scum that is difficult to remove.

3. When the speed is extremely low, the incision is too wide, and the arc is extinguished after the arc melts all the surrounding metal.

4. When the cutting speed is fast, because the plasma arc cannot completely penetrate the workpiece, the molten metal industry body cannot be completely blown away by the cutting gas, and part of the metal liquid stays under the plate to form scum.

5. The cutting speed is too fast, the plate is only partially melted, the plasma arc cannot penetrate the plate, and the molten metal liquid is blown into the air by the cutting gas and splashes; therefore, the appropriate cutting speed and current value of the CNC plasma cutting machine are important for cutting quality Guarantee.
