With the continuous development of social production and the continuous improvement of industrial processing technology, laser cutting technology is also constantly improving. Laser cutting machines are widely used in the sheet metal processing industry because of their advantages such as fast cutting speed, high precision, small slit and smooth incision. . So how should we test the quality of the laser cutting machine? Below, Suntop laser will introduce several criteria for judging the quality of laser cutting machines.
1. Roughness
When the laser beam emitted by the laser cutting machine acts on the metal sheet, vertical lines will be formed. The deeper the lines are, the rougher the cutting surface will be. In everyday use, it is often desirable to keep roughness as low as possible, so the lighter the grain, the better the cut.
2. Cutting width
Generally speaking, the cutting width does not affect the cutting quality, but because the cutting width determines the minimum inner diameter of the contour, when a particularly precise contour is formed inside the part, it will affect the cutting quality. Generally, the narrower the cutting width, the higher the cutting quality. As the thickness of the sheet increases, the cutting width also increases. Therefore, in order to ensure high-quality cutting results, a good laser cutting machine will keep the workpiece processing area constant to the greatest extent.
3. Verticality
If the thickness of the cutting material exceeds 10mm, it is necessary to pay attention to the verticality of the cutting edge. The more vertical the cutting edge, the higher the quality of the cut. The laser beam diverges gradually as it moves away from the focal point, and widens toward the bottom or top according to the position of the focal point, causing the cutting edge to deviate from the vertical line and thus affecting the cutting effect.
4. Glitch
During the processing of the laser cutting machine, the energy released by the laser beam irradiating the surface of the workpiece melts and evaporates the workpiece, and at the same time, the auxiliary gas blows off the slag on the surface of the workpiece, thereby realizing the cutting of the workpiece. If the auxiliary gas is not used, the slag will form burrs and attach to the cutting surface after cooling. Burrs are a very important factor in determining the quality of laser cutting, because removing burrs requires additional work, so the fewer burrs, the higher the cutting quality.
5. Pitting and Corrosion
Pitting and corrosion can adversely affect the cut surface, as well as affect appearance. Therefore, a good laser cutting machine should avoid pitting and corrosion.
6. Heat affected zone
The heat-affected zone refers to the depth of the region where the internal structure of the metal changes. Usually the shallower the depth of change, the higher the quality of the cut. During the laser cutting process, the area near the cut will be heated, which will also change the structure of the metal, which will adversely affect the cutting quality.
7. Deformation
If the cutting causes the metal part to heat up sharply, deformation can occur. This is especially important in fine machining. High-quality laser cutting machines usually have higher controllability, allowing better control of laser power, reducing part heating and avoiding deformation when using short laser pulses.
When purchasing a laser cutting machine, we can judge the quality of the laser cutting machine by proofing. Suntop laser has been focusing on the laser industry for 16 years.
