Since the fiber laser cutting machine officially emerged in 2011, it has gradually occupied the entire cutting market with a high-speed development trend in the following years, and replaced the traditional CO2 laser cutting technology. As of 2015, the power of fiber laser cutting machines has been continuously upgraded, and 6000W fiber laser cutting equipment has also come out, which can meet the processing of most metal materials. On the basis of 3000W, it has been continuously upgraded, and 6000W and higher power fiber laser cutting machines have also come into being. However, many people may not understand the difference between 6000w and 3000w fiber laser cutting machines. Today we will conduct a comprehensive comparative analysis of 6000W and 3000W fiber laser cutting machines.

1. Carbon steel bright surface cutting

Analyzing from the cutting thickness of the fiber laser cutting machine, the bright surface cutting thickness of the 3000W fiber laser cutting machine is about 10MM; compared with the 3000W fiber laser cutting machine, the bright surface cutting thickness of the 6000W fiber laser cutting machine is much greater than that of the 3000W fiber laser cutting machine. The bright surface thickness below 16MM can be cut, and the cutting speed is fast and the verticality is good.

2. Carbon steel full power cutting

Full power cutting means 100% power cutting. The 6000W fiber laser cutting machine has the advantages of high electro-optical conversion efficiency, good beam quality, and high power density. In actual operations, because the 6000W fiber laser cutting machine has the advantages of full power cutting ability, fast cutting speed, and small taper, carbon steel materials with a thickness of 16-25mm can be cut using the 6000W fiber laser cutting machine.

3. Stainless steel cutting

Compared with the 3000W fiber laser cutting machine, the 6000W fiber laser cutting machine meets the safety standards of laser equipment in developed countries in Europe and America. It uses laser beam cutting. Compared with the 3000W fiber laser cutting machine, the cutting speed of the 6000W fiber laser cutting machine can be increased by 140%~330%, which can effectively improve work efficiency.

4. Burr-free cutting

Common laser cutting machines use oxygen or nitrogen for operation. When the cross-section requirements are not high, the fiber laser cutting machine can also use air for cutting on this basis. The air is compressed into the storage tank by the air compressor, and it can be used after cooling and drying through the filter cooler. In this way, the user's use cost can be effectively reduced.

Among the fiber laser cutting machines of the same brand, the 3000W laser cutting machine can cut 2.5mm thick carbon steel and 10mm stainless steel materials without burrs; on the other hand, the 6000W can cut 5mm thick carbon steel and 16mm stainless steel materials without burrs. Among the fiber laser cutting machines of the same brand and type, the 6000W laser cutting machine can process materials with a thickness far exceeding that of the 3000W laser cutting machine.

The cutting power of the fiber laser cutting machine has far exceeded 6000W. The cutting power of the large-format gantry-type plane laser cutting machine equipped with a fiber laser can reach 30,000W, and the processing range can be infinitely extended. The machine tool guide rails can be infinitely extended, and multiple plates can be cut synchronously, which is suitable for large-format, medium and thick plate batch processing.
