Laser cutting is the laser beam emitted from a laser that is focused into a high power density laser beam via an optical path system. The laser beam is irradiated onto the surface of the workpiece to bring the workpiece to a melting point or boiling point, while the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the beam moves relative to the workpiece, the material is finally slit, thereby achieving the purpose of cutting.

 

From the principle of the laser cutting machine, we know that the laser cutting machine generates a large current at the moment of laser beam irradiation with the surface of the workpiece, and the temperature is high, and the current of the laser beam is reduced when the laser beam is not working, so that it will be repeated. The voltage has a huge impact. If the grid voltage is unstable, the voltage is high and low. This will affect the life of the main components of the laser cutting, cutting quality and cutting speed. Therefore, the laser cutting machine needs a matching voltage regulator to protect it. Equipment stability and reliability.

 

Laser cutting equipment has high requirements on the power supply stability of the power supply system. For example, the laser cutting equipment of Japan SNK Company is equipped with FANUC's CNC system. The requirements for the power supply are: three-phase AC 380 V±10%, 50 Hz± 1%, and most of the laser cutting equipment is designed with over/under voltage protection. Once the grid voltage is out of tolerance, the machine will automatically alarm and be protected. The allowable deviation of power supply voltage in China's power grid is ±10%, but in practice it often exceeds this standard, especially during peak hours of power consumption, such as one hour before and after work or during work, and often at night, even exceeding ±20. %. The machine is alarmed and cannot work properly, and damages the machine's power system. It even leads to the loss of relevant parameter data. This phenomenon has occurred in both laser cutting equipment and machine tools such as CNC machining centers or turning centers, and the frequency of occurrence is high, which should be taken seriously.

 

The special voltage regulator for laser cutting equipment is designed by our factory independently, combined with China's national conditions, to stabilize AC power. When the external power supply or load change causes voltage fluctuations, the stable voltage is automatically output.

 

Compared with other types of voltage regulators, the laser regulator special-purpose voltage regulator has the characteristics of large capacity, high efficiency, no waveform distortion, stable voltage regulation, and is applicable to a wide range of loads. It can withstand instantaneous overload and can work continuously for a long time. The self-control can be switched at will, with automatic protection devices such as over-voltage and over-current, as well as small size, light weight, convenient installation and reliable operation.
