With the continuous development of social production and the continuous progress of industrial processing technology, laser cutting technology is also improving. Laser cutting machine is widely used in sheet metal processing industry because of its advantages of fast cutting speed, high precision, small slit smooth incision and so on. So how should we test the quality of laser cutting machine? Below, Xiaobian will introduce several criteria to distinguish the quality of laser cutting machine.
When the laser beam from the laser cutting machine acts on the metal plate, the vertical grain will be formed. The deeper the grain is, the more rough the cutting surface will be. In daily use, it is usually necessary to minimize the roughness, so the shallower the grain, the higher the cutting quality.
Generally speaking, the cutting width does not affect the cutting quality, but because the cutting width determines the minimum inner diameter of the outline, it will affect the cutting quality when a particularly precise outline is formed inside the component. Generally, the narrower the cutting width, the higher the cutting quality. As the thickness of the sheet increases, so does the cutting width. So in order to ensure high quality cutting effect, good laser cutting opportunities to maximize the workpiece processing area to remain constant.
If the thickness of the cutting material is more than 10mm, it is necessary to pay attention to the perpendicularity of the cutting edge. The more vertical the cutting edge, the higher the cutting quality. When the laser beam is far away from the focus, it gradually diverges and widens toward the bottom or top according to the location of the focus, resulting in the deviation of the cutting edge from the vertical line and thus affecting the cutting effect.
Four, burr in the processing process of the laser cutting machine, the laser beam irradiates to the surface of the workpiece to release the energy to melt and evaporate the workpiece, and the auxiliary gas will blow off the slag on the surface of the workpiece, so as to achieve the workpiece cutting. If no auxiliary gas is used, the slag will form burrs on the cutting surface after cooling. Burr is a very important factor in determining the quality of laser cutting, because removing burr needs to add extra work, so the less burr, the higher the quality of cutting.
5. Dents and corrosion Dents and corrosion will have an adverse effect on the cutting surface and affect the appearance. So a good laser cutting machine should avoid depression and corrosion.
Heat-affected zone The heat-affected zone refers to the depth of the area where the internal structure of a metal changes. Usually the shallower the depth of the change, the higher the quality of the cut. During laser cutting, the area near the cut will be heated, and the structure of the metal will also be changed, which will adversely affect the cutting quality.
Seven, deformation if the cutting makes the metal parts heated rapidly, there will be deformation. This is especially important in fine machining. High quality laser cutting machines usually have higher control, allowing better control of laser power, reducing component heating and avoiding deformation when using short laser pulses.
