Products & services
Fiber Laser cutting
High-Speed Laser Cutting in XXL Our modern fiber laser cutting systems enable the greatest possible precision up to a format of 3000 mm width and 25,700 mm length at unusually high cutting speeds. We cut sheet thicknesses up to 30 mm in steel, stainless steel (oxide-free) and aluminum. Bevel cuts Up to a width of 2500 mm, we are able to apply bevel cuts up to +/- 45° on the outer contours, e.g. as weld seam preparation. Up to 3000 mm width we can also offer bevel cuts up to +/- 45° on inner contours. Tolerances We guarantee a positioning accuracy of +/- 0.1 mm and a repeat accuracy of +/- 0.05 mm as well as a cutting tolerance of +/- 0.1 mm/m cutting length. The remaining tolerances are based on DIN EN ISO 9013 or individual agreements.
Wasserstrahlschneiden
Our 2D/3D waterjet cutting system with two cutting heads and a cutting area of 3000 mm width and 10,000 mm length processes metals and plastics, stone, glass and other materials up to a thickness of 250 mm. It cuts with high precision and without structural changes. The 3D technology allows complex designs and often replaces machining.
Folding / Bending
With our hydraulic CNC-controlled press brakes with working lengths of 3,000 mm, 6,000 mm, 10,000 mm and 12,000 mm as well as pressing forces press forces from 800 kN to 20,000 kN, we have the right answer for almost any the right answer for almost any requirement. A wide range of special tools allow the production of complex profiles. Special upper and and bottom die sets are particularly suitable for the processing of high- and wear-resistant steels with high springback. Variable lower tools help to reduce set-up times.
Assembly groups
The welding production of complete assemblies is certified according to EN1090/EXC-2. We manufacture with certified welders and skilled workers. If desired, we also deliver the components ready painted (powder/wet paint) or hot-dip galvanized. We use the most common welding methods, such as MIG, MAG and TIG. Our overhead crane systems are designed for unit weights up to 10 tons. Further processing such as drilling, countersinking, thread cutting, chamfering and weld seam preparation complete our range of services.
CAD programming
We will be glad to assist you with the proper configuration of your construction, right from the design phase. In this way we will help you to find the option which is most cost-effective and at the same time meets all constructive requirements. It goes without saying that your data is in safe hands with us. Our information technology is always kept up to date and allows unproblematic data exchange in any common CAD data format. Filing, data administration and backups are well-established elements of our quality management.
Logistics
We are also happy to organize the transport for you. We either assign our house forwarders or coordinate the coordination with your contract carrier. The issuing of any necessary customs documents or loading into overseas containers is of course part of our service.
