What is laser cutting?
Here you will find answers to the most frequently asked questions about laser cutting. Find out more about the process, its advantages and possible applications as well as important technical details.
Precision laser cutting is a thermal cutting process in which a highly concentrated laser beam melts material at specific points. The laser beam is guided precisely along the desired cutting path. A process gas (typically oxygen or nitrogen) expels the molten material from the kerf, resulting in a clean, narrow cut. This enables clean and dimensionally accurate components, even with complex geometries and fine structural details.
In laser cutting, focusing optics concentrate the laser beam on a very small spot onto the surface of the material. The high energy density leads to localized heating well above the melting point. During the cut, the laser beam moves across the workpiece, with modern CNC control systems ensuring maximum precision and repeatability. The process is extremely flexible and enables quick adaptations to new designs or changes in production runs.
Laser cutting is a non-contact process that provides maximum design freedom. Due to the small heat-affected zone, residual stresses and distortion are kept to a minimum. The cutting quality is excellent and in many cases no post-processing is required. Very fine and complex internal contours can be realized, which would be very difficult to produce using mechanical processes. The high processing speed makes precision laser cutting an economical manufacturing method .

What our customers say about us
Questions and answers about laser cutting
Precision laser cutting is a high-precision process for cutting materials such as metal sheets, plastics and other sheet materials. A laser beam is used to cut the material precisely and without physical contact. The exact functionality and advantages of this process are explained here
Precision laser cutting can process a wide range of materials, including titanium, steel, stainless and alloy steels, non-ferrous metals and various plastics. It is important to know which materials are suitable for your specific project in order to achieve the best possible results.
The accuracy of precision laser cutting depends on various factors, including the thickness of the material. For sheet thicknesses up to 1.5 mm, the accuracy is usually +/- 0.01 mm to +/- 0.02 mm, while for sheet thicknesses up to 3.0 mm, an accuracy of +/- 0.03 mm is achieved. This precision makes the process ideal for demanding applications.
Precision laser cutting offers several advantages, including high accuracy, the ability to cut complex geometries and the ability to implement contour changes quickly and cost-effectively. It is also a cost-effective alternative to the classic punching process, especially for small and medium-sized series production.
Precision laser cutting is used in various industries, including the optical industry, micromechanics, medical technology, semiconductor technology and piezo technology. Typical applications include micro-drilling, micro-injection molds, micro-nozzles, solid-state joints and much more. This process enables the production of high-precision parts for a wide range of industries.
