Laser cutting machine types and technology selection

Laser cutting machines are available in several technology variants: Fiber laser cutting machines — the dominant current technology for metal cutting; fibre lasers use rare-earth-doped glass fibers to amplify the laser beam; available from 1kW to 30kW+ for sheet metal, with power determined by material thickness capacity; advantages include excellent electrical efficiency (wall-plug efficiency 30–50%), low maintenance (no laser gas, no mirrors), good beam quality for thin materials, excellent performance on reflective metals (copper, brass, aluminium), and lower operating costs than CO2; CO2 laser cutting machines — CO2 gas lasers producing 10.6 μm wavelength light; still preferred for cutting non-metals (plastics, wood, leather, textiles, ceramics) where fiber lasers do not absorb well; for metal cutting, largely displaced by fiber lasers except in very thin sheet applications where CO2 provides smoother edges; tube/pipe laser cutting machines — dedicated 6-axis or 4-axis laser systems for cutting, notching, and profiling round, square, rectangular, and structural steel profiles (I-beam, channel, angle); combining rotational and linear axes to cut complex patterns on tube and pipe; laser welding machines — fiber lasers used for high-speed, low-distortion welding of thin sheet metal (automotive battery housings, medical devices, electronics enclosures); and laser marking and engraving machines — low-power (20–100W) fiber, CO2, or UV laser systems for surface marking, engraving, and coding. Key specifications: laser source power (kW), cutting speed (m/min at given material and thickness), working area (m × m), positioning accuracy (±0.05mm typical for production machines), shuttle table or single table, laser source brand (IPG Photonics, nLIGHT, Raycus, Max Photonics), and CNC control (Beckhoff, PA, Fanuc).
