How to judge cutting quality of cnc laser cutting machine

Cnc laser cutting machine, as an efficient sheet metal processing tool, has widely using in various industries. But when many people choose cnc laser cutting machines, they don’t know clearly how to judge  laser cutting processing quality. So as to select and purchase high quality metal laser cutting machine products.

Harshness of cnc laser cutting machine work

Cnc laser cutting machine is a kind of high quality and high efficiency machining tool. When laser beam focus on the metal sheet, it will form vertical lines. And the deeper the grain is, the rougher the section surface is. When the power of the cnc 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 edge, but also affects the friction characteristics. In most cases, the lower the roughness, the higher the cutting quality.


Verticality of cnc laser cutting machine work

For high-power cnc laser cutting machine, when the thickness of the material exceeds 10mm, the perpendicularity of the cutting edge is very important. When away from focus, the laser beam diverges, cutting wider to the top or bottom depending on where the focus is. The cutting edge deviates from the vertical line by a few millimeters. The more perpendicular the edge, the higher the cutting quality.

Thickness of cnc laser cutting machine work

Generally speaking, cutting width does not affect cutting quality. The cutting width determines the minimum inner diameter of the profile. Especially when a particularly precise profile is formed inside the component. As the thickness of the plate increases, so does the cutting width. So to ensure the same accuracy, no matter what the width of the cut, the metal material should be constant in the processing area of the cnc laser cutting machine.

Burrs of cnc laser cutting machine work

In the process of metal laser cutting, the high energy produced by the laser beam irradiating the surface of the metal material. The laser beam rapidly vaporizes and evaporates the surface of the metal material. Blowing the slag off the surface of the metal material with the help of assist gas. If the assist gas is not used, when the slag is cooled, it will form a burr attached to the cutting surface. Since the removal of burrs requires additional work, the quality of the cutting can be judged intuitively by observing the number of burrs.
