At present, laser cutting machines are divided into several categories due to their different purposes and structures. Then enterprises should have a deep understanding of the classification of laser cutting machines when purchasing laser cutting machines. Now let’s analyze it together.
The principle of the laser cutting machine: after the laser is generated, four lenses of front mirror, rear mirror, reflector and condenser are transmitted to the nozzle, and auxiliary gas and 99% pure oxygen are sprayed from the nozzle as cutting gas to generate high temperature and certain pressure to cut through the workpiece. At present, laser cutting machines are mainly divided into three categories according to their structures, and their applicable cutting ranges are different. Therefore, enterprises need to understand before purchasing:
1. Carrying type: This laser cutting machine has the advantage of cutting thick plates, and has a large processing range. It can cut 2 * 6m or 3 * 9m plates directly on the machine.
2. Desktop computer: This machine has a fast processing speed when cutting thin plates, but the maximum effective cutting range is generally 1.5 * 3m.
3. The most commonly used large-scale laser machine in industry: it is mainly composed of nitrogen, helium, oxygen, carbon dioxide and kV high pressure to generate laser, of which four gases are 99% high purity gases.
