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, I do not know how to judge the quality of laser cutting machine processing. In particular, second-hand laser cutting machine buyers in the choice of laser equipment, often more blind, sometimes ignore the more important quality standards

First, metal laser cutting machine as an efficient sheet metal processing tool, has been widely used in various industries. But many people in the purchase or use of metal laser cutting machine, but clearly how to judge the processing quality of laser cutting machine, so as to choose high quality metal laser cutting machine products.

Two, roughness metal laser cutting machine is a kind of high quality and efficient processing tools, laser beam action on the metal plate, will form vertical lines, the deeper the lines, the more rough the surface of the section. Under the condition that the power of the cutting machine matches the thickness of the plate, the section cut by the metal laser cutting machine is smooth, no stripes, no brittle fracture. Roughness affects not only the appearance of the edge, but also the friction characteristics. In most cases, the lower the roughness, the higher the quality of the cut.

Three, perpendicularity for high-power metal laser cutting machine, when the thickness of the processing material is more than 10mm, the perpendicularity of the cutting edge is very important. Away from the focus, the laser beam diverges and the cut widens toward the top or bottom, depending on where the focus is. The cutting edge deviates from the vertical line by a few millimeters. The more vertical the edge, the higher the cutting quality.

Four, cutting width generally speaking, cutting width does not affect the quality of cutting, but in the component of the formation of a particularly precise profile, cutting width determines the minimum diameter of the profile, when the plate thickness increases, cutting width also increases. So to ensure the same accuracy, no matter how big the incision width, the workpiece in the laser cutting machine processing area should be constant.

Five, burr in the process of metal laser cutting machine, laser beam irradiates the high energy of the workpiece surface, so that the workpiece surface quickly vaporizes, and evaporates, and the auxiliary gas blows off the slag on the workpiece surface. If no auxiliary gas is used, the slag will form burrs on the cutting surface as it cools. Because the removal of burrs requires extra work, the quality of cutting can be directly judged by observing the number of burrs.
