In use, the CNC cutting machine selects the corresponding cutting method according to the different cutting conditions required. Today, Huafei CNC will explain the cutting precautions for different cutting situations.

1. Points to be noted in forging cutting

Because the scale on the surface of the forgings is thick, and the ignition point of the scale is higher than the melting point, it is prone to cutting interruption during cutting, which leads to a decrease in cutting quality and a reduction in work efficiency. Therefore, when cutting forgings, the oxide on the upper surface of the cutting area should be cut off first and then cut to improve the cutting speed and cutting quality.

2. The main points of anti-deformation in the cutting of rolled billet cold bed tooth plate

How to control the deformation of the workpiece during cutting is very important. For example, the conventionally planned cutting route will cause the target deformation and out-of-tolerance. Even if the shaping is performed, it is difficult to meet the size requirements, and the product will eventually be scrapped. Therefore, it is very important to arrange the gas cutting route reasonably.

3. Points to be noted in cutting thick plates

At the beginning of cutting, the oxygen pressure gradually increased, and finally reached consistency in the thickness direction of the steel plate. As a result, the steel plate is burnt and replaced at the cutting start position, and the workpiece starts to have defects at the cutting start end.

To avoid the occurrence of defects, the following methods can be used:

1. Use the ignition rod. The method is to add a steel plate close to the thickness of the steel plate at the cut-in point, and there is a gap at the close point. The cutting knife should cut from the ignition rod, and the ignition rod will guide the flame of the cutting tool to the bottom of the steel plate so that the burning speed of the steel plate is consistent. Get the best cutting section.

Ignition rods can be replaced by scraps that are cut downward. Small amount methods reduce the distance between the workpiece and the edge of the board, reduce the generation of corner material, and effectively improve the utilization rate of the board. Practical.

2. Use arc feed to increase the length of the appointment line and avoid direct entry points. This method has a better effect and is more widely used in production. Its disadvantage is wasted materials.
