How does the 12kw high-power laser cutting machine cut bright carbon steel?

In metal processing, laser cutting of carbon steel occupies a very important position, especially through the use of high-power laser cutting, burr-free cutting, bright surface cutting and other leading technology, high-quality precision workpieces can be obtained to meet welding, surface treatment, etc. Secondary processing requirements. As the thickness of the sheet increases, it is necessary to achieve bright surface cutting not only with the support of high-power lasers, but also with advanced cutting technology for parameter adjustment, including nozzle selection and focus position will affect the cutting effect.

Features of 10,000-watt laser cutting carbon steel:

The carbon steel plate is cut by oxygen and positive focus method. The thicker the carbon steel, the larger the positive focus and the larger the spot on the surface of the material. The larger the nozzle size (φ1.0-2.0mm) is required.

The effect of focus on carbon steel cutting

Within a certain focus range, the larger the positive focus, the smoother and brighter the carbon steel cutting surface.

The effect of nozzles on carbon steel cutting

The same focal point, the smaller the nozzle size. The smoother and brighter the carbon steel cutting surface, the smaller the taper.

How to choose the right nozzle and focus

If you want to achieve stable processing, you must choose to ensure that the nozzle temperature is not hot and does not continue to rise. Therefore, according to different carbon steel thicknesses, you need to choose a suitable nozzle and focus position. The following is the heating situation of the nozzle when the Chuangxin 12kw 10,000-watt laser is used to emit light for 30 seconds at full power:

Tips for cutting carbon steel thick plates with 10,000 watt laser

  1. Using full power and small nozzle cutting, it can cut products with smooth and small taper;
  2. The biggest problem with the 10,000-watt laser cutting carbon steel thick plates is that the nozzle is hot, so it is necessary to strictly adjust the light spot to the center of the nozzle;
  3. Ensure that the nozzle is not hot. The smaller the nozzle size, the larger the positive focus and the smoother the cut surface.
