How to judge the quality of metal laser cutting machine?

Many people in the purchase of laser cutting machine or second-hand laser cutting machine, do not know how to judge the quality of laser cutting machine processing. Especially when purchasers of second-hand laser cutting machine choose laser equipment, they are often blindly, sometimes overlooking more important quality standards. Metal laser cutting machine, as an efficient sheet metal processing tool, has been widely used in various industries. But many people choose or use metal laser cutting machine, but clearly how to judge the quality of laser cutting machine processing, so as to buy high-quality metal laser cutting machine products. Roughness Metal laser cutting machine is a high quality and efficient tool. When laser beam acts on metal plate, it will form vertical lines. The deeper the lines are, the rougher the cross-section surface is. When the power of the cutting machine matches the thickness of the plate, the section of the metal laser cutting machine is smooth, without stripes and brittle fracture. Roughness not only affects the appearance of the edges, but also affects the friction characteristics. In most cases, the lower the roughness, the higher the cutting quality. Verticality For high-power metal laser cutting, when the thickness of the material is more than 10 mm, the verticality of the cutting edge is very important. When away from the focus, the laser beam becomes divergent, cutting wider toward the top or bottom depending on the location of the focus. The cutting edge deviates from the vertical line by a few millimeters. The more vertical the edge, the higher the cutting quality. Cutting width Generally speaking, the cutting width does not affect the cutting quality, but when a particularly precise contour is formed within the component, the cutting width determines the minimum inner diameter of the contour, and when the thickness of the plate increases, the cutting width also increases. Therefore, in order to ensure the same precision, no matter how wide the incision width, the workpiece in the laser cutting machine processing area should be constant. Skin needling In the process of metal laser cutting machine, the high energy produced by the laser beam irradiating the workpiece surface makes the workpiece surface rapidly vaporized and evaporated, and the slag on the workpiece surface is blown away by auxiliary gas. If the auxiliary gas is not used, after the slag is cooled, burrs will form on the cutting surface. Because the removal of burrs requires additional workload, the quality of cutting can be directly judged by observing the number of burrs.铜焊丝,Copper Welding Rods,铝焊丝,aluminium welding wire,镍焊条,Nickel electrode,药皮焊条,Flux Coated Brazing Welding Rods
