The four points of the processing quality problems of CNC laser cutting machines can be revealed!

　　 The CNC laser cutting machine can guarantee a certain degree of accuracy when in use, and the cutting speed is relatively fast. It is necessary to pay attention to the processing quality when implementing the operation to prevent the quality problems of the processed workpiece. What needs to be clear is the processing time The problem with the incision. Next, I will give you a detailed introduction to the specific display of the processing quality problems of the laser cutting machine.

　　1. Cut smoothly, without streaks, and without brittle damage.

When the 　　 CNC laser cutting machine cuts thick plates at high speed, the molten metal will not appear in the cut below the vertical laser beam, but will be ejected from the place where the laser beam is deflected.

As a result, curved lines are formed on the cutting edge, and the lines firmly follow the moving laser beam. In order to correct this problem, the feed speed is reduced at the end of the cutting process, which can greatly eliminate the formation of lines.

　　2. The slit width is narrow, which is mainly related to the size of the laser beam spot diameter.

The cut width of 　　 CNC laser cutting machine generally does not affect the cutting quality. Only when a special contour is formed inside the part, the cutting width will have an important effect.

This is because the cutting width determines the smaller inner diameter of the profile. As the thickness of the sheet increases, the cutting width also increases. Therefore, in order to ensure the same high accuracy, regardless of the width of the cut, the workpiece should be constant.

　　3. The verticality of the crack is good, and the heat-affected area is small.

　　 Generally, laser cutting machines are mainly focused on the processing of materials below 5mm. The verticality of the section may not be the main evaluation factor, but in high-power laser cutting, if the thickness of the processed material exceeds 10mm , The verticality of the cutting edge is very important.

When leaving the focus, the laser beam will diverge, and the incision will expand to the top or bottom according to the position of the focus. The cutting edge is a few millimeters away from the vertical line. The more vertical the edge, the higher the cutting quality.

　　 4. No material burning, no molten layer formation, no large slag.

The residue of 　　 laser CNC cutting machine mainly appears on accumulation and cross-section burrs. The accumulation of material is due to the special oily liquid on the surface of the workpiece before the laser cutting starts to melt and perforate.

Various kinds of gasification, the material does not need to be blown away by the customer by the wind, but the upward or downward discharge will also accumulate on the surface.

A very important factor that determines the quality of laser cutting when the burr is formed is that the removal of the burr requires extra work, so the severity and amount of the burr can intuitively judge the quality of the cut.

　　 The above is the manifestation of the processing quality problems of the CNC laser cutting machine. Only by doing the above four points can the processing quality be guaranteed. This can also be done in the later processing. Guarantee the cutting quality of the workpiece. The width of the cutting and the size of the slit need to be paid attention to to prevent the overall use from being affected.
