What is a fiber laser cutting machine used for?

Fiber laser cutting is one of the latest developments in laser cutting technology, offering unprecedented speed and accuracy to the metal fabrication industry. But like most terms in the fabrication industry, fiber laser cutting sounds very complex. So what exactly is it? 

Cylion supply professional and honest service.

A fiber laser cutting machine uses active optical fibers to create a laser beam and a transport fiber to transmit this to the machine&#;s cutting head. This super hot laser is condensed down to a narrow beam and is used to cut through metals of various thicknesses. 

Fiber technology is used across a range of infrastructure and manufacturing applications for its enhanced strength and efficiency. There are several types of laser cutting machines in use today, and the fundamental difference between them is the way the laser is generated. Below, we&#;ll take you through a detailed guide of everything you need to know about fiber laser cutting.

What Is Fiber Laser Cutting?

Fiber laser cutting uses a type of solid-state laser to melt and pierce metals, achieving a precise and efficient cut. The laser medium for this technology is optical fibre, as opposed to gas or crystal, giving fiber laser cutting its name. 

Knowing that a laser is concentrated light, it makes sense that optical fibre can intensify this beam &#; hence why fibre is the &#;active gain medium&#; used to elevate the laser to a higher power state.

Fiber laser cutters can cut a range of materials and thicknesses depending on the capacity of the equipment. Most fiber laser machines can cut up cut stainless steel up to 10mm thick. 

This sort of laser cutter is commonly used in manufacturing and infrastructure, as fiber laser cutting machines are significantly more expensive than CO2 laser cutters, which are within the budget of schools and hobbyists. 

How Does A Fiber Laser Cutting Machine Work?

Fiber laser technology generates a focused, high-powered laser beam using stimulated radiation. A laser diode emits light, which is sent to the fiber optic cable to be amplified. When this powerful laser hits the material surface, the high-intensity light is absorbed and converted into heat, which melts the surface. 

A high-speed airflow that is parallel with the laser beam is used to blow away any molten material, allowing the workpiece to be cut.

The fibre laser&#;s first point of contact with the material must be more intense than subsequent interactions because, rather than simply cutting through the material, this first contact must pierce it. This requires using a high-powered pulse beam that works to put a hole in the material that lasts for about roughly ten seconds for a twelve millimeter sheet of stainless steel. Simultaneously, a high-speed airflow will clear out the debris to show a clear picture of the output. 

Typically, a fiber laser cutting machine uses computerised digital control technology, which allows the cutting data to be received from the computer-aided design workstation. These technologies aid in controlling either the surface of the material or the laser itself towards producing a specific pattern or design.

Fiber laser cutters also have dual interchangeable platforms that ease the loading and unloading of materials. This feature enables a speedy laser cutting process while maintaining accuracy and precision. 

A fiber laser cutting machine is also easy to maintain. The parts require few replacements and tune-ups, which reduces the burden and expenses of maintenance. In addition, fiber lasers use nitrogen in their cutting process, allowing for faster, more precise, and less messy cutting.

What Is The Difference Between A CO2 Laser Cutter And A Fiber Laser Cutter?

CO2 laser cutters and fiber laser cutters primarily differ in the mechanisms they use to generate and concentrate the laser. They also operate at different wavelengths and are suitable for different materials. This creates practical differences in efficiency and suitability for specific tasks. 

Mechanisms & Mediums

CO2 and fiber laser cutters use different mechanisms to cut materials. CO2 lasers use gases such as carbon dioxide, nitrogen and helium, and sometimes xenon or hydrogen. The machine mixes and excites these gases to produce a laser. 

Fiber lasers use elements such as erbium, ytterbium, neodymium or dysprosium. Mixing these elements together results in a crystalline solid as a fiber, and this is guided into the machine&#;s cutting head through a transport fiber. 

Wavelength 

Fiber laser cutters and CO2 laser cutters also work using different wavelengths. The laser produced by a fiber laser machine has a shorter wavelength than CO2 machines. This gives the fiber laser greater absorption power, which increases overall cutting speed and cutting quality.

Material & Thickness Suitability 

Another major difference between the two laser cutters is the material they work with. Fiber laser cutting is perfectly suited to sheet metal cutting which is vital to a lot of businesses. CO2 laser machines work more effectively for thick plate cutting. 

Efficiency & Output

Since the fiber laser machine can produce a cutting laser faster and more efficiently and cut through thicker materials, it has financial benefits for high-volume producers. CO2 lasers also need around ten minutes of warm-up time before they can operate well, which reduces efficiency and output.

What Materials Can A Fiber Laser Cut?

A fiber laser cutting machine is extremely useful in cutting sheet metal including carbon steel, stainless steel, copper, brass, aluminum and titanium. Fiber lasers excel in cutting reflective materials which CO2 lasers struggle with. 

It&#;s natural to think that because fiber lasers use some visible light that reflective materials such as brass, aluminium, and copper would pose a problem; but this is not the case. Fiber lasers are now much more advanced and can seamlessly cut through materials which once posed a challenge for metal fabricators. 

Sheet metal is one the biggest applications across the manufacturing, construction, and infrastructure industries. However, laser cutting is also becoming increasingly popular in the creative world, including metal art and sculpture. With the aid of a fiber laser cutter, metalworking is made much easier. 

How Thick Can A Fiber Laser Cut?

Fiber laser cutting machines have different cutting capabilities depending on their power, but almost all fiber laser machines can cut a sheet of metal that is up to 13mm thick. Higher powered fiber laser machines with 10kW of power can cut mild steel up to 2mm and stainless steel and aluminium up to 30mm. 

Advantages And Disadvantages Of Fiber Laser Cutting

With a better understanding of what fiber laser cutting is and how it works, we can identify some key benefits and drawbacks of fiber laser cutting machines. Being aware of the pros and cons of this technology will give you a much better point of reference when deciding whether one will benefit your workshop or metal fabrication project.

When compared to other types of laser cutting available, fiber lasers achieved high quality results at a faster rate and at a lower rate of materials consumption.

Disadvantages Of Fiber Laser Cutting

As advanced as fiber laser cutters have become, they still aren&#;t perfect and come with their own set of disadvantages. Using this list of disadvantages as a reference point can help you determine whether a fiber laser cutter is right for your workshop. 

• Fiber laser cutting machines and their components are more expensive to purchase 
• Lower-powered fiber laser machines show reduced cutting quality when processing thicker metals compared to CO2 lasers
• Fiber cutting machines do not leave as smooth a finish as CO2 lasers

As you&#;d imagine, because of its complicated operation and its variety of uses, fiber laser cutting machines are very expensive. But despite this and the few additional disadvantages, it is still apparent that there are greater advantages given by fiber laser cutting. With the development of technology, it&#;s likely all the disadvantages of fiber laser cutting will slowly get addressed and improved.

• • Fiber laser cutting machines work by using a computer-controlled laser to cut through materials. 

  • The laser beam is generated by a diode and then amplified in a Fiber optic cable. 

  • It is then focused through a lens and directed onto the material to be cut. 

  • The laser beam melts or vaporises the material, and a stream of gas blows away the molten or vaporised material.
