For new customers, when purchasing equipment, they will be asked to checklaser cutting machineProofing. In addition to the cutting speed of the equipment, proofing is more important for viewing the cutting quality of the sample and displaying the cutting quality of the laser cutting machine. What do customers need to pay attention to? This is a detailed introduction for everyone.

Roughness

The laser cut section will form a vertical line. The depth of the line determines the roughness of the cut surface. The shallower the line, the smoother the cutting surface. Roughness affects not only the appearance of the edge, but also the friction characteristics. In most cases, the roughness must be reduced as much as possible, so the shallower the texture, the higher the cut quality.

Verticality

If the thickness of the metal plate exceeds 10mm, the perpendicularity of the cutting edge becomes particularly important. When the distance is far away from the focal point, the laser beam will diverge, and depending on the position of the focal point, the cut will widen towards the top or bottom. The cutting edge is a few millimeters from the vertical. The more vertical the edge, the higher the cut quality.

Cutting width

The cutting width usually does not affect the cutting quality. The cutting width plays an important role only when a particularly precise contour is formed inside the part. This is because the cutting width determines a small internal warp of the profile. As the thickness of the sheet increases, the cut width also increases. Therefore, we want to ensure the same high precision, regardless of the width of the cut, the workpiece should be relatively stable in the processing area of the laser cutting machine.

Lines and glitches

When cutting thick plates at high speed, the molten metal does not appear in the cut below the vertical laser beam, but will be ejected at the back of the laser beam. As a result, curved lines are formed at the cutting edge, and these lines closely follow the moving laser beam. To solve this problem, reducing the feed speed at the end of the cutting process can greatly reduce the generation of lines.

Burr is an important factor to judge the quality of laser cutting. Since removing burrs requires additional work, the severity and number of burrs can directly reflect the cutting quality of the laser cutting machine.
