激光切割机批发供应商

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).

The global fiber laser cutting machine market is now dominated by Chinese manufacturers: Han's Laser Technology Industry Group (Shenzhen-listed, annual revenue ~USD 1.5 billion) is China's largest laser equipment maker — its fiber laser series covers 1kW to 60kW sheet metal machines, tube laser cutters, and laser welding systems at prices significantly below European equivalents. Han's Laser uses IPG (US), Raycus (China), and MAX Photonics (China) fiber laser sources. Bodor Laser (Jinan-based) is a major alternative with a strong international dealer network and competitive pricing. Other significant Chinese brands include HSG Laser, HG Laser, Hymson, and Golden Laser. Trumpf GmbH (Ditzingen, Germany) is the world's largest maker of industrial laser cutting machines and the quality benchmark — its TruLaser series uses Trumpf's own TRUMPF Disk lasers (TruDisk) and BrightLine Fiber technology for superior cut quality, especially on thick mild steel and stainless steel where cut face perpendicularity and surface roughness quality exceed Chinese machines. Trumpf machines are 3–5× the price of Chinese equivalents but deliver superior cut quality consistency, smaller kerf width (better material utilisation), lower maintenance frequency, and comprehensive global service support. For buyers in metal fabrication, HVAC, electrical enclosure, and structural steel fabrication where cut quality consistency and productivity are critical, Trumpf (or Bystronic, Amada, Mazak laser) machines justify the premium. For buyers in lower-precision applications (decorative metalwork, general sheet metal fabrication, signage) where Chinese machine cut quality is adequate, Han's Laser, Bodor, or HG Laser offer compelling price-performance. CE compliance for fiber laser machines requires compliance with the Machinery Directive (2006/42/EC) and Laser Product Safety standard EN 60825-1 — Class 1 enclosure (fully enclosed beam path) is required for unattended operation in workplaces.
