BYSTRONIC ByStar 4020 laser cutting machine

BYSTRONIC ByStar 4020 laser cutting machine was built in 2006 in Switzerland. The machine, designed to cut workpieces made of among others stainless steel and aluminium, uses a laser beam with a power of 4.4 kW and a thickness of just a few μm, which guarantees the highest precision and energy efficiency at low operating costs.

Laser cutting of workpieces with a maximum thickness of 25 mm takes place on a stable work table designed to provide unobstructed operator access to the workspace. After machining, the edges of the workpieces are distinguished by their unparalleled smoothness and absence of irregularities. The BYSTRONIC laser cutting machine is offered complete with equipment consisting of among others a BYSTRONIC CNC controller, a dust extraction unit and an EF COOLING cooling unit. The total weight of the machine is 18300 kg.
