The core features of laser tube cutting machines revolve around four dimensions: "core laser heat source, precise CNC system control, automated processing, and full process adaptability." Each feature precisely addresses the actual needs of tube processing and is the core reason for its rapid rise in the metal processing field:
The non-contact processing advantage of high-power laser heat sources. Tube laser cutting machines use 3000W or higher high-power fiber lasers as their core heat source. The laser beam, focused by a focusing system, forms a tiny spot with a diameter of only 0.01-0.05mm, achieving an energy density of up to 108W/cm². This instantly vaporizes and melts the metal tube material locally, achieving the cutting process.
This non-contact processing mode avoids the physical friction between the tool and the tube in traditional processing methods. There is no tool wear or consumable consumption. Simultaneously, the cut is smooth, burr-free, and deformation-free, eliminating the need for secondary grinding. This significantly improves processing efficiency and product quality, making it particularly suitable for processing precision tubes and tubes with complex contours.
In addition, fiber lasers have shorter wavelengths and higher absorption rates for metal pipes such as carbon steel, stainless steel, aluminum alloy, and copper alloy. They offer faster cutting speeds, lower energy consumption, and an electro-optical conversion efficiency of over 30%, far exceeding that of traditional CO₂ laser processing equipment, aligning with the development trend of green and low-carbon production.
