Many people are not sure how to judge the quality of the laser cutting machine when they are looking for laser cutting machines or used laser cutting machines. In particular, second-hand laser cutting machine buyers are often blind when choosing laser equipment, sometimes overlooking more important quality standards.
1. As a highly efficient sheet metal processing tool, metal laser cutting machine has been widely used in various industries. However, many people choose to use or use a metal laser cutting machine, but they also know how to judge the processing quality of the laser cutting machine, so as to purchase a high-quality metal laser cutting machine products.
2. the roughness
The metal laser cutting machine is a high-quality and high-efficiency processing tool. When the laser beam acts on the metal plate, vertical lines are formed. The deeper the grain, the rougher the surface of the section. When the power of the cutting machine is matched with the thickness of the sheet, the metal laser cutting machine cuts the section with smooth, no streaks and no brittle fracture. Roughness not only affects the appearance of the edges but also the friction properties. In most cases, the lower the roughness, the higher the cut quality.
For high-power metal laser cutting, when the thickness of the processed material exceeds 10 mm, the perpendicularity of the cutting edge is very important. When away from the focus, the laser beam becomes divergent and depending on the position of the focus, the cut becomes wider toward the top or bottom. The cutting edge is a few hundredths of a millimeter from the vertical line, and the more vertical the edge, the higher the cutting quality.
4.the cutting width
Generally speaking, the cutting width does not affect the cutting quality, but when a particularly precise contour is formed inside the part, the cutting width determines the minimum inner diameter of the contour, and as the thickness of the sheet increases, the cutting width also increases. Therefore, to ensure the same high precision, regardless of the width of the slit, the workpiece should be constant in the processing area of the laser cutting machine.
During the processing of the metal laser cutting machine, the laser beam illuminates the high energy generated by the surface of the workpiece, causing the surface of the workpiece to vaporize rapidly, and evaporating, and the slag on the surface of the workpiece is blown off by the auxiliary gas. If the auxiliary gas is not used, after the slag is cooled, burrs are formed on the cutting surface. Since the removal of the burr requires an extra workload, the quality of the cut can be visually judged by observing the number of burrs.
