Cnc 12kw fiber laser cutting is the laser emitted from the laser, through the optical path system, focused into a high power density laser beam. The laser beam irradiates to the surface of the workpiece, making the workpiece reach the melting point or boiling point, while the high-pressure gas coaxial with the beam will blow the melted or vaporized metal away. With the relative position of the beam and the workpiece moving, finally make the material to form a slit, so as to achieve the purpose of cutting.
12kw fiber laser cutting processing is to use invisible light beam instead of the traditional mechanical knife, with high precision, cutting fast, not limited to the cutting pattern restrictions, automatic typesetting to save material, smooth incision, low processing cost characteristics, will gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser tool head has no contact with the workpiece, so it will not cause scratches on the surface of the workpiece during work. Laser cutting speed is fast, the incision is smooth and smooth, generally without follow-up processing; The cutting heat affected zone is small, the plate deformation is small, and the cutting seam is narrow (0.1mm~0.3mm); No mechanical stress, no shear burr; High machining precision, good repeatability, no damage to the material surface; CNC programming, can process any planar graph, can be a large width of the whole plate cutting, no need to open a mold, economy and time saving.
Laser cutting machine has so many advantages, once encountered voltage instability (suddenly high and low, instantaneous mutation), the quality of the cut out will be affected, at this time you need to install a laser cutting machine to help power stability of the AC voltage regulator to ensure its own stability.
Ac voltage regulator is a kind of power supply circuit or power supply equipment can automatically adjust the output voltage, can fluctuate and meet the requirements of power equipment voltage stability in a certain set range, so that a variety of circuits or power equipment can work normally under the rated working voltage, but for laser cutting machine, how to choose? Next, we will analyze one by one for you:
1, the normal input voltage range is relatively wide relative to the conventional voltage regulator (general AC voltage regulator can be customized input range, conventional ±20%);
2, voltage regulator output voltage is three-phase 380V or single-phase 220V(can also be set according to the actual demand);
3, the voltage regulation accuracy needs to be within ±3% (laser cutting machine relative accuracy is relatively high);
4, the efficiency of the regulator to be up to 98%, its internal transformer insulation grade to reach H class;
5, the response time should be short;
6, avoid producing phase shift, and additional waveform distortion;
7, the regulator should have over voltage, over current, lack of equal automatic protection function
8, add automatic starting function (after overvoltage trip, when the mains restores to the voltage regulated range and the mains power cut and call again, the machine will start automatically)
9, add double delay mechanism (boot delay output, overvoltage delay shutdown, to avoid instant impact);
10, can work continuously for a long time, and can withstand short overload;
11, according to the needs of users in the output voltage regulator can be installed in different types of autotransformer or isolation transformer, to provide users with a variety of regulators, to meet the needs of different laser cutting machine.
