In the metal industry, there are many kinds of laser processing used, such as laser cutting plate, laser cutting tube, laser welding, etc. today, we take sheet metal processing as an example to tell you some key points that need to be paid attention to when selecting and purchasing flat laser cutting machine.
First of all, we need to know that the main selling points of laser cutting machine are fast cutting speed, excellent quality and exquisite products. For customers who want to buy laser cutting machine, leapion laser suggests that you first understand the following key elements:
1. When the laser cutting machine is cutting the thick plate at high speed, the molten metal will not appear in the incision under the vertical laser beam, but will spray out at the back of the laser beam. The curved lines will be formed at the cutting edge, and the lines will be generated closely following the moving laser beam. The solution is generally to reduce the feed rate at the end of the cutting process.
2. Roughness: the laser cutting section will form vertical lines, the depth of lines determines the roughness of the cutting surface, that is to say, the shallower the lines, the smoother the cutting section.
3. Perpendicularity; whether the angle of incision edge is vertical, and whether the slope is too large.
4. The cutting width, cutting width and incision width generally do not affect the cutting quality. The cutting width will have a certain impact only when a particularly precise contour is formed inside the part. 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. Dents and corrosion; dents and corrosion have a certain influence on the smoothness of cutting edge, but generally do not appear in the cutting error.
In addition to the above, when the user purchases the laser cutting machine, the user also selects the appropriate laser cutting machine according to the materials he needs to process.leapion laser cutting machine
