21 July 202622 July 2026Power Consumption of Fiber Laser Cutters and the Energy Efficiency of Raycus Laser Sources

The power of the laser source is not the same as the amount of electricity consumed by the machine. A 12-, 20-, or 30-kW fiber laser delivers a specific optical power for the beam, but it requires more electrical power...

14 July 202614 July 2026Materials and Optics for Fiber Laser Cutters — Nozzles, Lenses, and Protective Glasses

Materials and optical components have a direct impact on the stability of laser cutting, edge quality, and machine availability. Even a properly selected fiber laser cutter will not operate consistently if the nozzle is damaged, the protective glass is dirty,...

13 July 202614 July 2026Choosing an auxiliary gas for laser cutting: oxygen, nitrogen, or compressed air?

The assist gas is one of the most important—and at the same time most underappreciated—elements of the laser cutting process. It is responsible not only for removing molten material from the kerf, but also affects the course of the thermal...

08 July 202608 July 2026Operating Costs of a Laser Cutter — What Really Affects the Cost of Cutting

The operating costs of a laser cutter are a topic that cannot be reduced solely to the laser source’s power consumption. In practice, the entire process affects the cost of laser cutting: cutting time, gas type, energy consumption by the...

08 July 202608 July 2026Burrs and Edge Quality After Cutting — How to Diagnose Problems in Metal Cutting

A burr, a rough edge, an uneven edge, melt-through, jagged edges, or excessive bevel after cutting are indicators that help assess whether the metal-cutting process is proceeding correctly. They do not always indicate a serious problem, but it is always...

08 July 202608 July 2026Cutting Heavy Plate: Laser, Plasma, and Gas — Capabilities, Limitations, and Applications

For years, cutting heavy plate was mainly associated with plasma and gas, while fiber lasers were considered a technology for thin and medium-thickness sheets. Today, this distinction is no longer so clear-cut—modern high-power fiber laser cutters, with configurations of up...

26 June 202603 July 2026Cutting tubes, profiles, and structural sections on a single CNC machine

The production of components made from tubes, profiles, and structural sections is rarely uniform. A single facility may produce thin-walled hollow sections, round tubes, rectangular profiles, larger structural sections, and short assembly parts. This means that a machine for cutting...
