What is laser cutting

For laser steel cutting machine beginners, it is very important to understand what laser cutting is. Laser cutting is a kind of high energy generated by fiber laser to melt, burn or vaporize the material on the metal surface, so as to achieve the effect of cutting. Sheet metal laser cutting machine is widely used in fitness equipment, agricultural machinery production, advertising signs, precision electronics, steel structure fields, shipbuilding, aerospace fields, etc.

What factors affect laser cutting steel thickness

The factors of steel laser cutter include: fiber laser type, laser power size, laser cutting head brand, auxiliary gas type and focus size.

Fiber Laser Type:

  • CO2 lasers: mainly suitable for cutting, engraving and drilling
  • Fiber Lasers: Higher Cutting Accuracy, Faster Speeds

Fiber laser power:

The power of the laser determines the thickness of the laser cutting machine for steel. The higher the power, the thicker the steel plate cut and the faster the speed.

Generally, for cutting thin plates (0.2~4mm thick), it is enough to use 500W or 1000W cnc laser cutter steel.

Auxiliary gas

The type of assist gas used also affects the laser cutting capaticy. Typically oxygen, nitrogen and compressed air are used. Helps to increase cutting speed and can cut thicker steel plates.

Cut focus size

The size of the focus of laser cutting is also very important. The smaller the focus, the more concentrated the laser is, which can achieve the cutting effect of thick plates.
