To increase dramatically the speed with which sheet metal parts can be produced on a ByStar Fibre laser cutting machine from Bystronic, the Swiss manufacturer has introduced a new 10 kW fibre laser, the previous maximum power being 6 kW. In a separate announcement, the ByStar Fiber is now available with a sheet capacity of 4 m x 2 m in addition to the 3 m x 1.5 m version.
Compared with the industry-standard 4 kW fibre laser, the 10 kW source increases cutting speed by up to a factor of four. The greatest speed benefits are achieved in material thicknesses between 3 and 12 mm, although the high power also enables productive cutting of sheet thicknesses up to 30 mm. This will be of benefit to manufacturers that rely on fibre laser technology for all their cutting requirements, to the exclusion of CO2.
To integrate the 10 kW fibre laser source optimally into the ByStar platform, Bystronic has designed and produced a new cutting head. The in-house development incorporates a so-called Spot Control function, which automatically shapes the laser beam and flexibly adapts the focal point with high precision. Without operator intervention, cutting quality is optimised across a broad mix of materials, from thin to thick, including stainless steel, aluminium, brass, copper and ferrous metals.
