Today, with the continuous development of science and technology, the use of laser is becoming more and more extensive. As a kind of cutting machine commonly used in industry, laser cutting machines are so numerous that how can we judge the cutting quality of laser cutting machines when we choose and purchase them?

The quality of the laser cutting machine mainly depends on its cutting quality. The cutting quality should be checked from the aspects of perpendicularity, cutting width, and cutting roughness.

Perpendicularity deviation

If the thickness of the metal workpiece to be cut exceeds 10mm, the perpendicularity of the cutting edge is very important. When away from the focus, the laser beam will become divergent. According to the location of the focus, the cutting will become wider towards the top or bottom. The cutting edge will deviate from the vertical line by several millimeters. The more vertical the edge is, the higher the cutting quality will be.

Cutting width size

Generally speaking, the cutting width does not affect the cutting quality. Only when a particularly precise contour is formed inside the workpiece can the cutting width have an important impact. This is because the cutting width determines the minimum inner diameter of the contour. When the plate thickness increases, the cutting width also increases. Therefore, in order to ensure the same high accuracy, no matter how wide the incision is, the processing area of the object in the laser cutting machine should be constant.

Roughness

When the laser cutting machine finishes processing the workpiece, its section will form some relatively vertical lines, and the depth of the lines determines the roughness of the cutting surface. The shallower the section lines, the smoother the cutting surface. On the contrary, the deeper the section lines, the rougher the cutting surface. The cutting surface not only affects the appearance of the edges, but also affects the friction characteristics. In most cases, the roughness needs to be minimized, so the shallower the grain, the higher the cutting quality.
