Many customers begin to use CNC plasma cutting machine, feeling that the cutting sample is OK. But after using a period of time, you will find that CNC plasma cutting machine samples are good or bad. How can make good samples by CNC plasma cutting machine.

1. plasma Cutting current.

Increase cutting current can improve plasma arc power, but it allows current limit, otherwise it will cause the decline of plasma arc column is thicker and the kerf width increases, the electrode life.

2. Height of plasma  cutting nozzles.

The height of the cutting mouth refers to the distance from the end of the cutting nozzle to the surface of the workpiece being cut. The distance is generally 4~10mm. It is with electrodes Suliang within the same distance to the right, in order to give full play to plasma arc cutting efficiency, otherwise it will make the cutting efficiency and quality to drop or cut mouth burn.

3. Gas flow rate.

Increasing the gas flow can not only increase the arc column voltage, but also enhance the compression effect on the arc column, which makes the plasma arc energy more concentrated and jet force stronger, so it can improve the cutting speed and quality. But the gas flow is too large, but will make the arc column shorter, loss of heat increase, so that cutting ability is weakened, until the cutting process can not be normal.

There are many reasons that affect the cutting quality of CNC plasma cutting machine, and there are more knowledge about CNC plasma cutting machine, we continue to update for you.
