Metal Cutting Laser Cutter: How Fiber Laser Machines Cut Steel with Precision

How Does a Metal Cutting Laser Cutter Work?

A metal cutting laser cutter — specifically a fiber laser machine — works by generating a high-intensity laser beam through a fiber optic cable. This beam is focused to a tiny spot by a cutting head lens, melting and vaporising the metal at the cut line. An assist gas (nitrogen or oxygen) blows away the molten material, producing a clean kerf edge.

The CNC (Computer Numerical Control) system moves the cutting head according to your DXF or DWG design file — replicating any shape with ±0.1mm positional accuracy. This is why CNC metal cutting is the preferred method for architectural, industrial and decorative metal parts.

Fiber Laser vs CO2 Laser: Which is Better for Metal?

For metal, fiber laser wins decisively:

• Fiber laser (1070nm wavelength): Absorbed efficiently by all metals — MS, SS, aluminium, copper, brass. Fast cutting speed, low running cost, minimal maintenance.
• CO2 laser (10,600nm wavelength): Better for non-metals (acrylic, wood, MDF). Reflects off polished metals and struggles with high-reflectivity materials like copper and brass.

MetalWave uses CNC fiber laser machines — the industry-standard laser cutting machine for metal fabrication.
