XT Laser Medium Power Laser Cutting Machine
Compared with traditional sheet metal cutting, laser cutting produces higher quality cuts, greatly improves cutting speed, and can be cut into any shape. Moreover, the materials cut by laser cutting machines are also widely popular in the market, bringing many conveniences to the processing and manufacturing industry. The application of laser cutting carbon steel in industry is generally below 20MM. The cutting ability is generally below 40MM. The industrial application of stainless steel is generally below 16MM, and the cutting capacity is generally below 25MM. And as the thickness of the workpiece increases, the cutting speed significantly decreases.
Fiber laser cutting machines with different powers have different cutting capabilities and cutting thickness ranges. So, when choosing a suitable fiber laser cutting machine, how to choose the power of the laser cutting machine? Choose a high-power fiber laser cutting machine or a medium to low power laser cutting machine? Now we will take everyone to understand and understand. Let’s take the common medium and low power fiber laser cutting machine 500W-1000W as an example and analyze it for everyone:
Comparison of cutting process parameters between 500W and 1000W fiber laser cutting machines. Taking carbon steel materials as an example, the cutting speed of carbon steel below 2mm using a 500W machine is about 6.6 meters per minute, and the cutting speed using a 1000W machine is about 8 meters per minute; The cutting speed of 6mm carbon steel using a 500W machine is about 0.8 meters per minute, while the cutting speed using a 1000W machine is about 1.6 meters per minute. Using a laser with a power of 1200W to cut 2mm thick low-carbon steel plates can achieve a cutting speed of up to 600cm/min. And so on.
Taking stainless steel as an example, the cutting speed of stainless steel below 2mm using a 500W machine is about 8 meters per minute, while using a 1000W machine can achieve a cutting speed of about 17 meters per minute; The cutting speed of stainless steel with a thickness of about 3mm using a 500W machine is about 0.4 meters per minute, while the cutting speed using a 1000W machine is about 1.4 meters per minute, indicating a significant difference. From this, it can be seen that when facing the 500W and 1000W fiber laser cutting machines, the 1000W fiber laser cutting machine is clearly the wiser choice.
In the era of CO2 laser cutting, the maximum power of the laser was limited to 6000W. In the early days, the thickness of fiber laser cutting plates was also limited to 20mm for carbon steel and 12mm for stainless steel. For thicker materials, traditional processing techniques such as fine plasma, wire cutting, or water jet cutting were still used. The revolutionary change that the 10000 watt level fiber laser cutting has borne the brunt in the field of sheet metal processing is the continuous improvement of the machinability thickness of different materials: aluminum alloy plates can reach 40mm, stainless steel plates can reach 50mm. With the successive introduction of 12kW and 15kW fiber laser cutting machines, the thickness limit of material cutting will continue to be broken.
Data shows that the overall energy consumption of the fiber optic cutting system is about 3 to 5 times less than that of the CO2 cutting system, resulting in an energy efficiency improvement of over 86%. When cutting materials up to 6mm thick, the cutting speed of the 1.5kW fiber laser cutting system is equivalent to the cutting speed of the 3kW carbon dioxide laser cutting system.
In addition to the increase in cutting thickness, the cutting efficiency of 10000 watt level laser cutting in the field of medium and thin plates is also improved by multiple levels. When cutting stainless steel plates with a thickness of 3-10mm, the cutting speed of a 10kW laser cutting machine is more than twice that of a 6kW machine; At the same time, the 10kW laser cutting machine can achieve a fast bright surface cutting speed of 18-20mm/s in the cutting application of carbon steel, which is twice the speed of ordinary standard cutting; Compressed air or nitrogen can also be used to cut carbon steel within 12mm, with a cutting efficiency six to seven times that of oxygen cutting carbon steel. The speed of improving the efficiency of high-power laser cutting thin plates has greatly exceeded people’s past imagination, which is also the main reason why high-power laser cutting machines are popular in the sheet metal market.
