The laser cutting machine is to focus the laser emitted from the laser into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the laser beam will blow the molten or vaporized metal away. With the movement of the relative position of the beam and the workpiece, the material forms a cutting seam, thus achieving the purpose of cutting.

1. Perforation of thick carbon steel plate

Piercing time accounts for a large proportion in thick plate processing, and various laser manufacturers have developed rapid piercing technology. The more representative is high-energy piercing (hole blasting). The advantage of this method is that it is fast (1 second, taking t16mm as an example - the same below). The defect is that it not only affects the processing of small shapes, but also the huge energy injected during the piercing increases the temperature of the plate and affects the overall cutting process. However, if a small power pulse is used for piercing, the time will be very long (12 seconds), which will lead to the reduction of cutting efficiency and the increase of unit cost.

2. Cutting surface quality problem

Cutting sections are often encountered when processing medium and thick plates. Such cutting is not only questioned about the quality of the finished products, but also accompanied by excessive burning and serious slag sticking, so that it does not reflect the value of high-priced laser processing machines compared with other cutting methods. 3. The stability of the whole plate processing

In the whole plate processing of domestic steel, the phenomenon of poor processing in local areas often occurs. This phenomenon is sometimes very random, even when the machine is in good condition.
