Basic operation principles of a fiber metal cutter

Metal laser cutting: operating principles and advantagesHow to choose a fiber metal cutter How to choose a fiber metal cutter

The main tool of a fiber metal cutter is a laser beam with a high concentration of energy. The basis is thin fused quartz fibers and semiconductor diodes. Power of the equipment depends on the number of these diodes.

Inside the fiber, there is:

  • an ytterbium coated main fiber;
  • secondary conducting guides carrying the function of semiconductors.

When diodes start radiating light, semiconducting material saves energy and transfers it to the core. Thus, the ytterbium coating comes into action and starts generating a concentrated beam.

The fiber component of the machine is always encased in a polymer cable. Also, for additional power production, there are reflecting mirrors at the ends of the cable.

If the operation of a laser fiber metal cutter is considered from the outside, the algorithm looks as follows:

  • an operator activates the equipment;
  • diodes come into action;
  • the fiber is filled with energy and generates a beam;
  • the operator starts the set processing program;
  • the beam falls on the lens of the emitter and then focuses on the material.

After that, the machine runs according to preset program settings. The material is processed in a non-contact manner. The laser beam has enough energy to instantly heat up and melt material. The high temperatures cause the material particles to vaporize, and thus the cutting process is carried out.

Fiber metal cutters advantages

  • High-quality processing. The equipment is capable of creating incredibly complex products with high accuracy and performance. Currently, there is no comparable method with similar quality results.
  • Short pay-off period. Some people believe that laser equipment is an expensive and unprofitable purchase. However, this is wrong. Fiber optic equipment reduces labor costs, allows producing extremely complex and high-quality items, and is characterized by a long service life.
  • Easy usage. The control of fiber metal cutters is software-based. This ensures easy operation, a wide range of functions available, and high productivity.
  • Wide range. The equipment is available in various sizes and configurations. There is a wide choice of small machines and large industrial machines. Therefore, you can easily choose the most optimal machine for your tasks.

What can a fiber metal cutter do?

The main advantage of fiber metal cutters is their versatility. They can be used for:

  • producing doors;
  • engraving industrial products;
  • complex cutting out of metal items;
  • production of décor elements and more.

Laser metal cutters have also found their application in the automotive, aircraft, and shipbuilding industries.

What are the criteria for choosing a metal cutter?

It is worth noting that the model of the fiber metal cutter to be purchased should be suitable for the tasks and specific of production. The fiber metal cutter can be used for the following types of machining:

However, despite the versatility of the equipment, you should pay attention to the production scale (mass or single-item) and to the thickness and type of the material to be processed. These things should be noted when choosing a fiber metal cutter according to the criteria listed below.


Most manufactures turn out laser sources with a quite wide power range from 0.35 kW to 25 kW. This is the most important criterion you should take into account because the power of a metal cutter laser source determines the thickness of the material you will be able to process on this equipment as well as the machining speed. Let us use some examples for the sake of clarity.

A 0.5 kW laser source is able to cut a 1 mm stainless steel sheet at 12 m/min. The maximum thickness for this emitter is 3 mm (at 0.7 m/min), and it cannot cut aluminuim due to the high reflectivity of this metal.

A 1.5 kW laser source cuts a 3 mm stainless sheet at 4.5 m/min and can handle aluminium up to 3-4 mm (at 0.8 mm).

While a 6 kW laser source can easily cope with stainless steel up to 18 mm and aluminium alloy up to 14 mm. Being one of the leaders in “high-speed modes”, it cuts 3 mm of stainless steel at a speed of around 15 m/min.

Thus, if your main task is to cut large sheets of metal at maximum productivity, you should consider fiber metal cutters with higher power in order to save time due to the high machining speed.

On the other hand, if you are not engaged in mass production, a laser machine with less power and price but still quite capable of performing the required task will be a more optimal choice.

Working area

The size of the working area required is determined by the dimensions of the material to be machined. Once you have decided on the metal you are going to work with, you will know the necessary working area of your future equipment.

Different types of metals have various dimensions. For example, stainless steel sheets come in sizes varying in width from 1000 mm to 1250 mm and in length from 1250 mm to 5000 mm while aluminium sheets come in the following sizes: 900x1800 mm, 1200x1800 mm, 1200x2400 mm, 1500x3000 mm, etc.

According to these dimensions, manufactures all over the world have worked out the most common dimensions for metal cutting machines. For the fiber metal cutters, they are 1300x2500 mm and 1500x3000 mm. However, there are also customized machines with a larger working area (1500x4000 mm, 2000x4000 mm, 2000x6000 mm, etc.).
