Several problems that should be paid attention to when cutting perforation by sheet laser cutting machine

Laser cutting machine refers to the energy released when the laser beam is irradiated on the surface of the workpiece to melt and evaporate the workpiece, which has achieved the intention of cutting and carving. It uses the laser beam emitted from the laser generator to pass through the optical path system, and then is concentrated into a high-power laser beam. The laser heat is absorbed by the workpiece material, and the temperature of the workpiece rises sharply. After reaching the boiling point, the material begins to vaporize and form holes. With the high-pressure air flow, as the relative position of the beam and the workpiece moves, the material finally forms a slit.

When cutting the sheet, the advantage of the laser cutting machine is to cut the medium and thin sheets of 25cm and below. When cutting the sheet, what needs to be done is to perforate. As the thickness of the sheet increases, the difficulty of perforation and the time of perforation will increase accordingly. Improving the cutting effect during the cutting process is what we need to discuss.

1. Add the lead wire and reserve the perforation position
When cutting the workpiece, in order to achieve a better cutting effect, we generally choose to add cutting leads around the workpiece, so as to avoid the traces left by the perforation and achieve a better cutting effect. Except for the flying cutting mode, basically all Apply this method.

2. First perforate the whole, clean the surface after perforation, and then cut
When encountering thicker plates, the impact of perforation is large. When perforating, the surface of the plate is easy to form metal slag. If it is not cleaned in time, it will directly cause damage to the laser head. Therefore, when cutting thicker plates, you can First, collective perforation is adopted, and all the holes required for cutting the part are pierced at one time. After the perforation is completed, the machine is stopped to deal with the molten slag caused by the perforation, and then the normal cutting process can be carried out, and satisfactory results can be obtained.

3. Specific analysis of specific materials
When cutting different materials, the cutting power will be different, especially when cutting high-reflection materials such as aluminum and copper. Improper operation may cause direct damage to the laser. If you are uncertain, you can consult an after-sales engineer. Baiwei Laser will escort you 24 hours a day.
