The comparision between plasma cutting machine and fiber laser cutting machine

Plasma laser cutting can be used if the requirements for cutting parts are not high, because the advantage of plasma is cheap. The cutting thickness can be a little thicker than the fiber. The disadvantage is that the cutting burns the corners, the cutting surface is scraped, and it is not smooth. Generally, the high requirements cannot be reached. Also, it consumes a lot of power. Frequent maintenance and repairs are required.

Fiber laser cutting machine is a popular model in recent years. The advantage is that the cutting speed is fast. High cutting precision. The cut surface is smooth. Low maintenance cost. Low power consumption. The disadvantage is the high price. The initial investment cost is high.

Laser cutting is to use a high-power density laser beam to scan the surface of the material, heat the material to several thousand to tens of thousands of degrees Celsius in a very short time, melt or vaporize the material, and then use high-pressure gas to remove the melted or vaporized material from the slit. Blow away in the middle to achieve the purpose of cutting the material. Laser cutting, as it replaces the traditional mechanical knife with an invisible beam, the mechanical part of the laser head has no contact with the work, and will not damage surface during work; the laser cutting speed is fast, and the incision is smooth and flat, generally no need Subsequent processing; small heat-affected zone of cutting, small plate deformation, narrow slit (0.1mm~0.3mm); no mechanical stress in the incision, no shearing burr; high machining accuracy, good repeatability, and no damage to the surface of the material; CNC programming, It can process any plan, and can cut the whole sheet with a large format without opening the mold, which is economical and time-saving.

Detailed distinction between laser cutting and plasma cutting:

1. Compared with plasma cutting, laser cutting is much more precise, the heat affected zone is much smaller, and the kerf is much smaller;

2. If you want precise cutting, small cutting seam, small heat-affected zone, and small deformation of the plate, it is recommended to choose a laser cutting machine;

3. Plasma cutting uses compressed air as the working gas and high-temperature and high-speed plasma arc as the heat source to partially melt the metal to be cut, and at the same time, use high-speed airflow to blow away the melted metal to form cutting;

4. The heat-affected zone of plasma cutting is relatively large, and the cutting seam is relatively wide, which is not suitable for cutting thin plates, because the plates will be deformed due to heat;

5. The price of laser cutting machine is a little more expensive than plasma cutting machine;
