LASER PRECISION CUTTING - SMALLEST KERFS AND 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 almost no limits to the contours and geometries.
In addition to conventional 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
Precision cutting is a thermal cutting process in which a focused laser beam in combination 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.

Scope of Service
The following variants of laser cutting are possible with our laser systems or as part of our laser job shop:
We use tests to determine which specific process is most suitable for manufacturing and machining your precision products.
In this variant, the material to be cut is inflamed and burned by adding oxygen.
The gas pressure of the added oxygen ensures that residues such as slag and melt are blown out of the kerf.
Flame cutting is characterized by high cutting speeds, but leaves oxidized cut edges.
Similar to flame cutting, fusion cutting involves the supply of a process gas whose gas pressure 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 shielding gas.
The cutting speed is lower than with flame cutting. Oxidation of the cut edges, on the other hand, is avoided.
Due to extremely short laser pulses, the material passes directly from a solid to a gaseous state during sublimation cutting. There is no molten phase. The material therefore evaporates or vaporizes.
This process also uses an inert gas such as argon or nitrogen.
Sublimation cutting with ultrashort pulse laser technology generates little thermal stress, which means that the material retains its desired properties and keeps its dimensional stability.
