How to see the quality of laser cutting machine equipment is good or bad

Now laser cutting machine equipment is widely used in all walks of life. So how can we judge a laser cutting machine cutting quality? 1. Cutting roughness. Laser cutting section will form the vertical grain, grain depth determines the cutting surface roughness, the lighter the grain, the cutting section is more smooth. Roughness is not only affect the appearance of the edge, but also affect the friction characteristics, in most cases, the need to reduce the roughness as far as possible, so the more shallow, grain, the higher the cutting quality. 2. Cut verticality. How the thickness of the sheet metal for more than 10 mm, the cutting edge of vertical degree is very important. Away from the focus, the laser beam divergence, according to the location of the focus, cutting towards wider at the top or bottom. Cutting edge what percentage deviation from vertical line mm, margin is vertical, the higher the cutting quality. 3. Cutting width. Incision width in general will not affect the cutting quality, only the outline of special precision is formed within the parts, the cutting width is important, because the cutting width determines the contour of the small Canon, when the sheet thickness increases, the cutting width also will increase. So want to ensure that the same precision, no matter how hard it is incision width, artifacts in processing areas of the laser cutting machine should be constant. 4. Cutting lines. When high-speed cutting plate, molten metal won't appear in vertical laser beam at the bottom of the incision, may in the laser beam after partial. As a result, the curved lines formed in the cutting edge, texture closely to follow a moving laser beam, in order to fix this problem, at the end of cutting processing to reduce the feed rate, can greatly eliminate grain line. 5. The cutting burr. Burr formation when determining the quality of laser cutting is a very important influence factors, because of the burr removal need extra workload, so the burr can serious and how much is the intuitive judgment of the quality of the cutting. 6. Material deposition. Laser cutting machine at the start of piercing in workpiece surface with a layer of oil before the special liquid. Gasification and all kinds of materials in the wind except incision without customers, but the upward or downward discharge will be formed in the surface deposition. 7. Sag and corrosion. Sag and have an adverse effect on the surface of the cutting edge of corrosion, affect the appearance. They appear in general should avoid cutting error. 8. | laser cutting in the heat affected area, along the area around the incision is heated. At the same time, the structure change of the metal. For example, some metal hardening will happen. Heat affected area refers to the depth of the internal structure change in the region. 9. Deformation, if cut sharply heating parts, it will be out of shape. This is especially important in the fine processing, because the outline and the connection piece is usually only a few millimeters wide ten points. Control of laser power and the use of short laser pulse can reduce parts heat, avoid deformation. By understanding these points can be intuitive to see the quality of laser cutting machine equipment is good or bad, it is also judge a laser cutting machine is good or bad intuitive good method.
