Advantages of laser cutting

Laser cutting is commonly regarded as a economical and precise cutting process for metals and many other materials. Among the advantages repeatedly listed are precision, economy, and versatility. But what exactly are the advantages? Today, we want to take a closer look at the often-described advantages of laser cutting.

Precision, accuracy and quality

Among the most important arguments of laser cutting is the precision and quality of the laser parts. Using the appropriate cutting gases, the precise laser beam guidance, the high power density and a high cutting speed enable highly precise contour accuracies of ± 0.01 mm, exact, almost right-angled cut edges and clean cut surfaces. Depending on the material thickness, narrow cut gaps (kerf) of 0.03 mm are also possible. Unlike competing cutting processes, laser cutting does not involve contact between the cutting tool and the workpiece. The laser beam processes the material without contact and with a low thermal load.

In addition, laser cutting is characterized by excellent quality of the workpieces produced. The laser beam of the laser cutting systems is focused so strongly that the kerf is only slightly larger than the laser beam itself. This allows the finest geometries to be produced and duplicated with tolerances of ± 0.1 millimeter. The cutting edges are so clean during laser cutting that post-processing is often not necessary.

Laser cutting is a particularly fast and clean cutting process that is also often more economical than other cutting processes. However, the advantages of material separation with light also include high repeatability, dimensional accuracy and contour accuracy.


  • Contour accuracies of ± 0.01 mm
  • Cutting gaps (kerf) of 0.03 mm
  • Tolerances of ± 0.1 mm
  • Exact, almost right-angled cut edges
  • Clean, burr-free cut surfaces
  • Low thermal stress


Another advantage of the technology is its versatility. Laser cutting represents a high-tech tool for precisely cutting through sheet steel and metal (light and heavy), ceramics, plastics, textiles and even for many fiber composites. No other cutting process can be used so effectively and easily on so many materials.

Moreover, many laser cutting systems are capable not only of pure cutting, but also laser drilling and engraving. So with one setup process, different processes can be performed to machine a laser part by combining the processes. This increases precision and cost-effectiveness and reduces the probability of errors due to multiple setups and alignments.


  • Material variety
  • Combination cutting, drilling and engraving
  • Suitable for prototypes and series
  • Fine geometries


Laser cutting can also excel in economics. Due to the high cutting speeds and small kerf, sheets can be processed quickly and efficiently with laser cutting. A comparable material utilization is not achieved with any other process.

In addition, laser cutting requires no tools, which not only results in low setup and wear costs. Another decisive advantage is also that geometries can be changed and adapted at short notice at any time. Thanks to the simple transfer of job data to the laser machine, a job can be started within a very short time after commissioning and with very low setup costs.

Since laser parts usually have very clean and almost burr-free cut edges, costly and time-consuming post-processing is not necessary in many cases.


  • High cutting speeds
  • No tooling
  • Low setup costs
  • No post-processing
  • High material utilization (small cutting kerfs)
  • Simple data processing
