As an efficient sheet metal processing tool, metal cutting laser machine has been widely used in various industries. When buying a metal laser cutting machine, many people do not know how to judge the processing quality of the metal laser cutting machine and often blind.
Usually we judge the cutting quality and the reliability of the whole product through the following points:
1. Roughness
Metal cutting laser machine is a high-quality and efficient processing tool. When the laser beam acts on the metal sheet, it will form vertical lines. The deeper the lines, the rougher the surface of the section. When the power of the cutting machine matches the thickness of the sheet, the section cut by the metal laser cutting machine is smooth, free of streaks, and no brittle fracture.
2. Vertical degree
For high-power metal cutting laser machine, when the thickness of the processed material exceeds 10mm, the verticality of the cutting edge is very important. Away from the focus, the laser beam diverges and the cut widens towards the top or bottom, depending on where the focus is.
3. Cutting Width
Generally, the cutting width doesn’t affect the cutting quality, but when a particularly precise contour is formed inside the component, the cutting width determines the minimum inner diameter of the contour. When the thickness of the sheet increases, the cutting width also increases.
4. Burr
In the process of metal laser cutting machine, the high energy generated by a laser beam shining on the workpiece surface makes the workpiece surface vaporize and evaporate rapidly, and the slag on the workpiece surface is blown off by auxiliary gas. If auxiliary gas is not used, the slag will form burrs attached to the cutting surface after cooling.
