Abrasive Waterjet Cutting 
In abrasive waterjet cutting, as with pure waterjet cutting, standard purified tap water is pressurized to approximately 4000 bar using a high-pressure pump. Unlike pure waterjet cutting, an abrasive material (such as garnet sand or corundum with a grain size of approx. 0.2–0.5 mm) is added to the water jet. Due to the high velocity of the jet, a vacuum is created that draws the abrasive material into the mixing chamber. The jet is then focused through an abrasive focusing nozzle, producing a cutting jet with a diameter of approximately 0.8–1 mm. Abrasive waterjet cutting is used for cutting harder and thicker materials, such as metals, plastics, stone, tiles, and glass.
Pure Waterjet Cutting
This cutting process is primarily used for soft and thin materials, such as leather, paper, rubber, foam, and textiles. In this process, standard purified tap water is pressurized to approximately 4000 bar using a high-pressure pump.
The pressurized water is then focused through a sapphire nozzle, forming a cutting jet with a diameter of approximately 0.10–0.35 mm. The waterjet reaches a speed of around 2.5 times the speed of sound, making it possible to achieve high cutting speeds, depending on the material being processed.
Advantages of Waterjet Technology
- Cold cutting process, ensuring distortion-free cutting of all materials. There is no thermal influence, and therefore no structural changes within the material.
- Any contour can be cut, with the ability to start and end the cut at any point on the workpiece surface.
- No direct mechanical contact with the workpiece, preventing deformation and enabling high cutting precision without fraying or heavy burr formation. The material surface remains undamaged.
- The fine cutting jet ensures high cutting accuracy, allowing even delicate and complex contours to be produced.
- Environmentally friendly, as there is no dust or chip generation, no chemical air pollution, and no use of emulsions or oils.
- Cost-effective and fast programming through direct import of your files (e.g., DXF, DWG, IGES).
- Due to the principle of “stationary workpiece – moving cutting head”, there are no large mass accelerations and therefore no vibrations that could affect cutting quality.
- Even challenging materials (coated or reflective materials, laminates, etc.) can be processed without difficulty.
- Cost reduction through economical production of individual parts.
- High material utilization through optimized nesting of components.
Our Services
Programming
Our programming department is equipped with state-of-the-art CAD/CAM workstations. Based on your specifications, drawings, templates, or digital data, we create the required programs including all lead-ins and drilling operations. Using specialized software, the parts are optimally nested to ensure the most efficient and cost-effective use of materials.
Finally, the most efficient machining sequence is defined, the programs are converted into NC data, and transmitted via our company network directly to the machines for processing. These programs are stored in our database, allowing you to reorder previously manufactured parts even years later without the need for reprogramming.
Materials
There are hardly any materials that we cannot cut…
- Aluminum, copper, brass, steel, stainless steel, titanium, wire mesh
- Plastics (PP, PE, PA, PVC, …), acrylic glass, Makrolon, Plexiglas, aramid (Kevlar, Nomex, Twaron, …), GFRP, CFRP, laminates (Pertinax, …), rubber, brake linings
- Glass, laminated glass, bulletproof glass, granite, marble, stone, terracotta, tiles

Formats
On our machines, we can process plates with maximum
dimensions of 4000 × 2200 mm.
In principle, we are able to process material thicknesses of up to 200 mm, although the maximum value varies depending on the material.
Based on our experience, metals can be efficiently cut up to approximately 80 mm, while plastics can be cut up to around 100 mm.
