In the process of using the CNC cutting machine, we will find the problem of the excessive cutting slope. Many customers on the Internet are also asking the same question. Today we will analyze the problem of the large cutting surface slope of the CNC plasma cutting machine.

We have found through many years of research and practice of CNC cutting machines that the incline angle of the cutting surface is related to the cutting material and the quality of the plasma power supply used. For example, when using a CNC plasma cutting machine to cut soft metals such as aluminum and titanium alloys, the roughness is poor and the cut surface is uneven. When cutting carbon plates, the roughness is equivalent to flame cutting. It is also 25um, but the tilt angle Larger.

Different types of plasma power supply have slightly different cutting surface roughness, and different cutting gases will also affect the cutting roughness. Plasma cutting has high requirements for speed adjustment and cutting height. Water cutting can easily leave cutting slag. The content of unburned metal in the slag is more than that of flame cutting, which is relatively difficult to remove.

Friends who have used a CNC plasma cutting machine or who know the cutting machine know that when using ion arcs to complete the cutting of steel plates and other materials, the cutting surface of the CNC plasma cutting machine will be inclined at a certain angle. In actual processing, different operation processes and accessory configurations will cause inclined surfaces with different angles.

The cuts of the workpieces cut by CNC plasma cutting machines are generally neat, and the cutting slope is estimated to have the following reasons:

1. The slits cut by the CNC plasma cutting machine are related to the air pressure. The air pressure from the cutting nozzle is too small. The quality of the slit is not good;

2. The cutting torch did not correct when cutting, that is, did not grasp the cutting angle;

3. If the cutting nozzle of the cutting gun is used for too long, it will affect the cutting seam if it is not replaced. After the cutting nozzle is used for a long time, the front air outlet will be deformed, that is, it is not very round, which will affect the airflow of the air outlet. Crooked, the slit is crooked;

4. The quality of the thin plate cut by the larger CNC cutting machine will be better, but the quality of the small machine is not ideal.

When the elliptical plasma arc of the CNC plasma cutting machine penetrates the cutting material, the elliptical arc surface will incline the cutting surface at a certain angle. In practical applications, we need to know what the angle of inclination is according to different processing needs. To determine whether the cut material can meet the requirements of secondary processing.

It is normal for CNC plasma cutting machine to cut with a slope. Generally speaking, the ordinary plasma slope is within 15 degrees, and the fine plasma or laser-like plasma slope is within 5 degrees.

If you are not satisfied with the cutting effect of the CNC plasma cutting machine, you can appropriately reduce the distance between the plasma nozzle and the steel plate, a minimum of 2-3MM is appropriate. 14MM steel plate, input air pressure at 1.0MPA, current 160A. If the cutting quality is very high, it is recommended to use a CNC flame cutting machine for the carbon steel plate.
