Laser cutting is a thermal cutting process for processing sheet metal. The laser beam is created by the laser source (resonator), conducted by a transport fiber or mirrors in the machine cutting head where a lens focuses it at very high power on a very small diameter. This focused laser beam meets the sheet metal and melts it.
Bystronic uses two types of laser sources: Fiber laser and CO₂ laser.
Fiber lasers are the most efficient way in laser cutting. The laser beam is created by an active fiber and transmitted over a transport fiber to the machine cutting head. Fiber lasers are significantly smaller than CO₂ lasers and generate several times the power from the same amount of current. A fiber cutting system is primarily suited for processing thin to thick sheet metal from steel, stainless steel, aluminum and also other non-ferrous metals (copper and brass).
A CO₂ laser uses a gas mixture to create the laser beam. The necessary high voltage in the resonator is created with the help of wear-free semiconductor excitation modules. Bystronic relies on such modules since they are smaller, more efficient and reliable than traditional solutions.
A wide selection of various, powerful laser sources is one of Bystronic’s trademarks. All lasers are high-quality and highly energy efficient, not least because of their high efficiency. The portfolio contains both fiber and CO₂ lasers.
