Fiber Laser Cutters: Revolutionizing the Manufacturing Industry

Fiber laser cutters have ushered in a new era in manufacturing, providing faster, more efficient, and precise cutting capabilities. With their versatility to cut metals to exact proportions, these machines have proven invaluable for metalworking shops and manufacturing firms.

What is a fiber laser cutter?

A fiber laser cutter is an automated laser-cutting machine equipped with a CNC (computer numerical control) controller. It uses a high-power fiber laser beam focused into a tiny spot to melt and vaporize metal materials for cutting custom shapes and patterns.

Fiber lasers utilize glass fibers doped with rare-earth elements as the lasing medium, which is pumped by high-power semiconductor diodes to emit a laser beam with a wavelength of 1.064 microns. This produces a high-quality, high-power-density beam that is easily absorbed by metals.

Key Benefits

Compared to traditional CO2 or solid-state lasers, fiber laser cutters offer superior performance.

  • Higher precision: Positioning accuracy up to 0.05mm allows intricate cuts with fine details.
  • Faster speeds: cutting speeds up to 10x faster than CO2 lasers, over 60 m/min.
  • Smoother cuts: The laser vaporizes material, leaving smooth, burr-free edges. Surface roughness is controlled to Ra6.3.
  • Lower costs: more energy efficient with 30% electrical to optical efficiency. Lower gas, maintenance, and consumable costs.
  • Compact size: The all-fiber design eliminates complicated optics, decreasing footprint.
  • High stability: fiber laser generators last up to 100,000 hours between maintenance.

Cutting Capabilities

Today’s high-power fiber lasers can cut metal over 1 inch thick. The maximum thickness varies by material:

  • Carbon steel: 50mm
  • Stainless steel: 40mm
  • Aluminum: 40mm
  • Brass/Copper: 25mm

Fiber laser cutters can process all types of metals.

  • Carbon steel
  • Stainless steel
  • Alloy steel
  • Tool steel
  • Aluminum
  • Copper
  • Brass
  • Titanium
  • And more

They are widely used to cut sheets, plates, pipes, tubes, and metal profiles.

Industrial Applications

Major industries that utilize fiber laser cutting include:

  • Automotive – Cutting body panels, chassis, and engine parts
  • Aerospace – Aircraft structural components and engine parts

  • Just-in-time processing
  • Flexible manufacturing

How to Choose a Fiber Laser Cutter

Key considerations when selecting a fiber laser cutting machine:

  • Materials/thickness – Match laser power to your application
  • Cutting speed – Faster is more productive
  • Power levels – Consider operating costs
  • Precision requirements – Tighter tolerance cuts need higher accuracy
  • Cutting mode – 2D flatbed or 3D cutting
  • Brand reputation – Reliability and service matter
  • Budget – Prices range from $15,000 to $500,000

Work with your laser cutting equipment supplier to properly specify the right machine for your needs.

The Future of Fiber Laser Cutting

Fiber laser technology will continue advancing, with higher power levels enabling faster speeds and thicker capacity cuts.

Trends shaping the future include:

  • Higher power lasers – Up to 100kw fiber lasers will emerge
  • Increased automation – More robotic laser cutting systems
  • Improved beam control – Better focus and precision
  • Specialty fiber designs – Optimized for specific metals
