Introduction of CO2, YAG and fiber laser cutting machine
In recent years, we have found that whether it is a carbon steel plate processing company or a stainless steel plate processing manufacturer, they prefer laser cutting machines. This is because laser cutting can better meet their requirements and the cutting speed is fast. , The cutting precision is high, the cutting cost is low, and it is relatively environmentally friendly, which can bring a comfortable working environment to the workers in the workshop and improve their work efficiency. However, for steel plates of different thicknesses, the selected laser equipment is different. Hua Yucheng Laser will introduce you to several commonly used laser cutting equipment here. You can determine whether to buy this equipment according to their characteristics and performance.
1. CO2 laser cutting machine
Main advantages: high power, general power is between 2000-4000W, can cut full-size stainless steel, carbon steel and other conventional materials within 25 mm, as well as aluminum panels within 4 mm and acrylic panels within 60 mm, wood material panels, and PVC panels , And the speed is very fast when cutting thin plates. In addition, because the CO2 laser outputs a continuous laser, it has the smoothest and best cutting section effect among the three laser cutting machines when cutting.
Main disadvantages and disadvantages: Since most of the core and key technologies of CO2 lasers are in the hands of European and American manufacturers, most of the machines are expensive, most of which cost more than 2 million yuan, and the related maintenance costs such as accessories and consumables are extremely high. The operating cost is very high, and the cutting time consumes a lot of gas. It is difficult or even impossible to cut aluminum, copper and other high-reflective materials. Main market positioning: 6-25mm thick plate cutting, mainly for large and medium-sized enterprises and some pure Laser cutting and processing enterprises that process externally, but due to insurmountable factors such as large maintenance loss of their lasers and large power consumption of the host, their market has received huge impacts from solid-state laser cutting machines and high-power laser cutting machines this year, and the market is shrinking significantly It is estimated that the CO2 laser cutting machine will be replaced by the latter two after the further development of the laser in the future.
2. YAG solid laser cutting machine
Main advantages: It can cut aluminum plates, copper plates and most non-ferrous metal materials that other laser cutting machines cannot cut. The machine purchase price is cheap, the use cost is low, and the maintenance is simple. Most of the key technologies have been mastered by domestic companies, and the price of accessories and maintenance The cost is low, and the machine is simple to operate and maintain, and the quality of workers is not high. Main disadvantages and disadvantages: It can only cut materials below 8mm, and the cutting efficiency is quite low.
Main market positioning: cutting below 8mm, mainly for self-use small and medium-sized enterprises and most users of sheet metal manufacturing, home appliance manufacturing, kitchenware manufacturing, decoration and decoration, advertising and other industries that have not particularly high processing requirements, and gradually replace wire cutting, CNC punching, Traditional processing equipment such as water cutting and low-power plasma.
Main advantages: high photoelectric conversion rate, low power consumption, can cut stainless steel plates and carbon steel plates within 12MM, is the fastest laser cutting machine for cutting thin plates among these three machines, small slits, good spot quality, and can be used for fine Cutting.
Main disadvantages and disadvantages: At present, most of the core and key technologies of fiber lasers are in the hands of one or two manufacturers in Europe, America and other countries, so most of the machines are expensive, most of them cost more than 2 million, and the low-power ones are basically in the hands of About 1 million yuan, and related maintenance costs such as accessories and consumables are extremely high. Due to the very thin fiber slits during cutting, the air consumption is huge (especially when nitrogen cutting), and the fiber laser cutting machine is difficult or even unable to cut aluminum, copper, etc. Reflective material and very slow when cutting thick plates.
Main market positioning: cutting below 12mm, especially high-precision processing of thin plates, mainly for manufacturers that require extremely high accuracy and efficiency. It is estimated that with the emergence of lasers of 4000W and above, fiber laser cutting machines will eventually replace CO2 high-power lasers Most markets for cutting machines.
