The Indispensable Guide to Fibre Laser Cutting Machines

November 22, 2023


Cutting-edge technology continues to revamp traditional industries, paving the way for ingenious processes and fostering the evolution of better, faster, and more efficient production methods. At the heart of this technological revolution is laser cutting, a procedure that ensures precision, finesse, and aesthetic quality in various production processes. In this all-encompassing guide from Koenig Machinery, we will shed detailed light on fibre laser cutting machines - exploring their multitudinous applications, transformative benefits, and operational use tailored to elevate your business performance significantly.

Fibre laser cutting systems work on a simple yet high-tech principle: the use of an optical fibre infused with rare-earth elements, like ytterbium, as the laser source. These compact machines are lauded for their ability to generate a highly focused beam of light that ensures sharp, precise cuts on a myriad of materials, from metals to thick, engineered plastics.

Thriving in industries that demand high-speed precision and detailing, fibre laser cutting technology has been a game-changer. Its efficacy in reducing production time without compromising accurate, clean, and high-quality cuts makes it an invaluable asset in industries like electronics, automotive, aerospace, and general manufacturing.

As you navigate this comprehensive guide, we will draw your attention to the practical use of fibre laser cutting in everyday business operations, how to make informed choices when investing in a fibre laser cutting machine, and the best practices to ensure your machine's longevity and optimal performance. 


Fibre Laser Cutting Technology Explained

In the realm of laser cutting machines, fibre laser cutting stands out as one of the most efficient and advanced processes on the market. 

The fiber laser cutting power starts as a series of pumped light sources, this light is essentially taken, combined together and the erroneous wavelength light is separated out and the usable orwanted wavelength is concentrated into a “doped” optical fiber cable. With the removal of this lower wavelength and amplification you are left with a laser beam that has a perfect wavelength that has an optimal absorption rate into metal. This wavelength then travels through the optical fiber cable into your laser head where a lens is used to precisely adjust your focal point onto the surface of your material. 

Fibre lasers utilise optical fibre doped with rare-earth elements to channel laser energy, creating a highly focused, precise, and powerful cutting beam. Through their exceptional capabilities, fibre laser cutting machines have attracted substantial interest from businesses seeking to streamline production, improve cutting precision, and increase productivity.

Exploring the Applications of Fibre Laser Cutting

1. General Manufacturing and Fabrication: Given the wide range of materials used in manufacturing, fibre laser cutting machines are vital to efficient production lines. Their ability to cut through most metals grants businesses the flexibility to cut custom parts and create unique products. A fiber laser will produce a very superior edge result vastly lowering and post production finishing. With the use of preset cutting profiles and the use of DXF files increases the ease of use on a fiber laser and speeds up the transition from one job to the next.

2. Aerospace Industry: Precision is critical in the world of aerospace engineering, and fibre laser cutting machines live up to the challenge. Their ability to cut intricate designs into thin metals reduces production time, lightens overall workloads, and ultimately contributes to a reduction in production costs.

3. Automotive Industry: With vehicles relying on countless metal components of varying shapes and sizes, fibre laser cutting machines have turned the intricate cutting process into a breeze. Capable of producing detailed and complex cuts on metals like steel, aluminium, and copper, fibre lasers enhance accuracy and efficiency in automotive component manufacturing.

    Maximising Your Fibre Laser Cutting Machine's Performance

      1. Proper Calibration and Alignment: To ensure your fibre laser cutting machine operates at its fullest potential, you must perform regular calibrations and alignments. Proper calibration maintains the laser's focus on the cutting surface and enables precise cuts. Alignment refers to the machine's internal lens in the laser head. This should be regularly checked and adjusted to maintain the laser beam’s path for optimal performance. Unlike with CO2 lasers there are no mirrors or vacuum pumps that need adjustment or aligned.

      2. Regular Maintenance: Routine maintenance checks are vital for peak performance. This includes cleaning the machine's interior, replacing consumables such as nozzles and lenses, and inspecting core components for wear. A well-maintained fibre laser cutting machine will display a greater level of efficiency, accuracy and dependability in your production line.

      3. Material Selection: Choosing the right materials for your fibre laser cutting machine can impact both productivity and precision. Be sure to select compatible materials to prevent potential damage to your machine or the objects being worked on. Common materials for fibre laser cutting include metals such as mild and stainless steel, aluminum, brass and copper. A fiber laser has a wavelength specifically for cutting of metals. Acrylics and organic materials can not be cut with a fiber laser. Dual layered materials such as alucobond (aluminum sandwich with a rubber type internal) can not be cut.

      4. Appropriate Cutting Conditions: Experimenting with the cutting speed, power, and gas flow settings will allow you to discover the optimal cutting conditions for your specific production needs. Finding the perfect balance between speed and precision is imperative for thorough cuts and an efficient workflow. When you as the customer is after speed over edge result, adjustments can be made to the cutting profiles. This is especially attractive when a secondary processing application will accrue. Allowing for a reduced production cost and machine time.


      Selecting the Ideal Fibre Laser Cutting Machine for Your Business

      When deciding on the right fibre laser cutting machine for your business, thoroughly consider factors such as size, cutting capability, and target material compatibility. Additional aspects like software compatibility, cutting area size, and automation capabilities can impact your production process and should feature in decision-making. Consulting with laser-cutting experts like Koenig Machinery can help you make an informed investment and select the most suitable laser-cutting system for your business needs.
