LASER PRECISION CUTTING - SMALLEST CUTTING GAPS AND MOST FILIGREE CONTOURS
Today, laser cutting with modern CNC machines is one of the most variable, precise and dynamic cutting processes available. Thanks to modern laser technology, almost any material can be cut with high precision. There are virtually no limits to the contours and geometries.
In addition to classic sheet metal processing, the production of metallic and non-metallic precision parts such as thin foils or tubes is the most important field of application.
PROCESS - INTERACTION OF LASER BEAM AND PROCESS GAS FLOW
Precision cutting is a thermal cutting process in which a focused laser beam combined with a coaxial process gas flow produces a very narrow cut. Due to a relative movement between the laser beam and the workpiece, flat parts as well as tubes and three-dimensional contours can be realized with high precision and kerfs of 10 µm and smaller.

Performance overview
The following variants of laser cutting are possible with our laser systems or within the scope of our contract manufacturing:
Flame cutting
Fusion cutting
Sublimation cutting
We are happy to test which specific process is suitable or most suitable for the manufacture and machining of your precision products.
Application examples
Process variants
Flame cutting
In this variant, the material to be cut is ignited and burned by adding oxygen.
The gas pressure of the added oxygen ensures that slag and melt are blown out of the kerf as residues of the combustion.
Flame cutting is characterized by particularly high cutting speeds, but leaves oxidized cutting edges.
Fusion cutting
Similar to flame cutting, fusion cutting also involves the supply of a process gas, the gas pressure of which is also used to blow the melt out of the kerf.
However, it is not oxygen that is used to ignite the material. Rather, nitrogen or argon are used as the protective gas.
The cutting speed is lower than with flame cutting. Oxidation of the cut edges, on the other hand, is avoided.
Sublimation cutting
Due to extremely short laser pulses, the material passes directly from a solid to a gaseous state during sublimation cutting without a molten phase. It thus evaporates or vaporizes.
This process also uses an inert gas in the form of argon or nitrogen.
Sublimation cutting with ultrashort-pulse laser technology produces little thermal stress, allowing the material to retain its desired properties and remain warp-free.
