In the metal industry, there are many kinds of laser processing currently used, such as laser cutting plate, laser cutting pipe, laser welding, etc. We take sheet metal processing as an example to tell you some key points to pay attention to when selecting and purchasing laser cutting machines.
First of all, we need to know that the main selling points of the laser cutting machine are fast cutting speed, good quality and exquisite products. For customers who want to purchase laser cutting machines, Chuyu Laser suggests that you first understand the following key elements:
Some key points to be understood when purchasing laser cutting machine
1. When the laser cutting machine is cutting thick plates at high speed, molten metal will not appear in the incision below the vertical laser beam, but will be ejected at the back of the laser beam. The curves will be formed at the cutting edge and will follow the moving laser beam to generate these lines. The solution is usually to reduce the feed rate at the end of the cutting process.
2. Roughness: The laser cutting part will form a vertical line, and the depth of the line determines the roughness of the cutting surface, that is, the shallower the line, the smoother the cutting part.
3. Verticality; Whether the angle of the cut edge is vertical and the slope is too large.
4. The cutting width, cutting width and incision width usually do not affect the cutting quality. Only when a particularly accurate contour is formed inside the part, the cutting width will have a certain effect. This is because the cutting width determines the minimum inner diameter of the profile, and when the thickness of the sheet increases, the cutting width also increases.
5. Depression and corrosion; Dents and corrosion have a certain effect on the smoothness of the cutting edge, but usually there is no cutting error.
In addition to the above, when users purchase laser cutting machines, they also choose appropriate laser cutting machines according to the materials they need to process.
