XT Laser-laser cutting machine

In recent years, the rapid development of China’s high-speed railway, nuclear power, shipbuilding, petrochemical, aerospace and other fields has put forward higher requirements for laser cutting equipment and technology.

Therefore, from 6000W to 8000W, and then to the 10000 watt laser cutting machine, the power of the laser cutting machine has exceeded our imagination step by step. In the past, the thickness of optical fiber laser cutting plate was limited to carbon steel within 20mm and stainless steel within 12mm, while the Wanwa laser cutting machine could cut aluminum alloy plate below 40mm and stainless steel plate below 50mm. When cutting stainless steel plates with a thickness of 3~10mm, the cutting speed of the 10kW laser cutting machine is more than twice that of the 6kW laser cutting machine. At the same time, in the cutting application of carbon steel, the 10000 watt laser cutting machine can achieve fast bright surface cutting of 18~20 mm/s, twice the normal standard cutting speed. You can also use compressed air or nitrogen to cut carbon steel within 12mm, and the cutting efficiency is six to seven times that of oxygen cutting carbon steel.

According to data, for 8mm stainless steel, the speed of 6kW laser cutting machine is nearly 400% higher than that of 3kW laser cutting machine. For 20mm thick stainless steel, the speed of 12kW is 114% higher than that of 10kW.

From the perspective of economic benefits, the price of the 10000-watt laser cutting machine is less than 40% higher than that of the 6kW machine tool, but the output efficiency per unit time is more than twice that of the 6kW machine tool, and it saves labor and labor. It is favored by the owners of laser processing companies.

The objects of laser cutting machine include stainless steel, carbon steel, alloy steel, aluminum plate, silver, copper, titanium and other metal materials.

For different metal materials, the cutting thickness of different power laser cutting machine has a great relationship with the cutting material. How thick can the laser cutting machine of 1000 watts and 2 kilowatts cut?

Generally speaking, the thickness limits of various materials cut by different power laser cutting machines are as follows:

(For reference only, the actual cutting capacity is also related to the quality of the cutting machine, cutting environment, auxiliary gas, cutting speed and other factors).

1. The maximum thickness of different materials cut by 500W fiber laser cutting machine: the maximum thickness of carbon steel is 6mm. The maximum thickness of stainless steel is 3mm. The maximum thickness of aluminum plate is 2mm. The maximum thickness of copper plate is 2mm.

2. The maximum thickness of different materials cut by 1000W fiber laser cutting machine: the maximum thickness of carbon steel is 10mm. The maximum thickness of stainless steel is 5 mm. The maximum thickness of aluminum plate is 3mm. The maximum thickness of copper plate is 3 mm.

3. The maximum thickness of different materials cut by 2000W fiber laser cutting machine: the maximum thickness of carbon steel is 16mm. The maximum thickness of stainless steel is 8 mm. The maximum thickness of aluminum plate is 5 mm. The maximum thickness of copper plate is 5 mm.

4. The maximum thickness of 3000W optical fiber laser cutting machine for cutting different materials: the maximum thickness of carbon steel is 20mm. The maximum thickness of stainless steel is 10mm. The maximum thickness of aluminum plate is 8mm. The maximum thickness of copper plate is 8mm.

5. 4500W laser can cut stainless steel up to 20mm, but the quality of the cutting surface above 12mm cannot be guaranteed, and the cutting surface below 12mm is absolutely bright. The cutting capacity of 6000W will be better, but the price is also higher.

In the practical application process, the cutting ability of the fiber laser cutting machine is also related to the quality of the cutting machine, the type of laser, the cutting environment, the cutting speed and other factors. The use of auxiliary gas can also improve the cutting ability to a certain extent, so there is no absolute standard to judge its cutting thickness. For example, the cutting of carbon steel mainly depends on oxygen combustion, and the cutting of stainless steel mainly depends on power. Generally speaking, the 1000W fiber laser cutting machine can cut about 10mm carbon steel plate, while the stainless steel plate is slightly more difficult to cut. If you want to increase the cutting thickness, you must sacrifice the edge effect and speed.
