Laser cutting machine is often considered as a cutting machine with higher cutting efficiency and better cutting quality. People are increasingly applying it to metal processing. However, the quality evaluation of laser cutting has not yet reached a uniform standard in the world. Therefore, when buying steel laser cutter, customers don’t know how to judge the quality of laser cutting machines.
In this case, we have summarized four points for your reference.
1. Smooth cutting surface, less texture, no brittle fracture.
When cutting the plate at high temperature, the traces of the molten material will spray out at the rear of the laser beam. As a result, curved lines are formed. To correct this problem, if the feed rate is reduced at the end of the cutting process, the formation of lines can be greatly eliminated.
2. Width of slit
The cut width generally does not affect the cut quality, unless a particularly precise contour is formed inside the part. This is because the cutting width determines the minimum inner diameter of the contour. As the thickness of the sheet increases, the cutting width also increases. Therefore, we want to ensure the same high accuracy, regardless of the width of the cut, the workpiece should be constant in the processing area of the laser cutting machine.
3.The verticality of the slit is good, and the heat affected area is small.
When the material’s thickness exceeds 18mm, the verticality of the cutting edge is very important. As you move away from the focus, the laser beam becomes divergent. The more vertical the edges, the better the cut quality.
As a thermal cutting processing application equipment, it is bound to cause thermal impact on the material during its use. Mainly of them include three aspects: a. Heat affected area; b. Depression and corrosion; c. Material deformation.
So you should have known how to judge the quality of steel laser cutter. SENFENG LASER has manufactured laser machine since 2004 with rich experience. We can provide you the best service to meet your demands. More details, welcome to contact us!
