Extrusion tools are now used for a wide range of applications in a variety of designs and sectors. We supply our extrusion tools and individual parts for extrusion systems for pipe, section, hose and cable production around the globe. Our in-house design department is always open to listen to your individual requirements, virtually all of which we are able to realise in the Würz Group.
Cold roll forming plays an increasingly important role in forming technology. At the same time, there are also growing demands on the concentricity, service life, rolling speed and material selection. We are a competent contact for all your questions and a qualified supplier of groundbreaking rolls for precise forming techniques. KÄMPFER WÜRZ manufactures work, intermediate and backup rolls for all cold roll goods and all types of rolling mills. We also supply rolls with a diameter of up to 600 mm and a maximum length of 2500 mm. To meet concentricity or cylindrical form requirements, we produce rolls with a maximum shape deviation or position deviation of less than 2 µm. The rolls are produced using classic cold rolled steels as well as PM steels, hard metals and ceramics. RW9200 and RW9600 hard metals have proved highly successful, guaranteeing a tool life of up to one year. We manufacture rolls in solid hard metal or with a hard metal coating, and in steel for two-high, four-high stand or multi-roll mills as well as wire rolling mills and turks heads. If desired, we supply our rolls complete with all the necessary bearings and accessories. Rollers for roll mills and strip processing lines round off our extensive product range. As part of our roll services, we offer an extensive and efficient range of repair, reworking and regrinding services. You can also benefit from our collection and delivery service.
The rolls predominantly applied for the section rolling of wire are used to manufacture wires in everyday products, e.g. in mobile telephones, power distribution devices and even electric toothbrushes. It is possible to differentiate between two areas here. On the one hand, section rolls with macro sections, where the sections are ground using a dressed shaped grinding wheel. This enables the grinding of very large profile cross sections in equally large rolls with a diameter of up to 600 mm and a length of 2500 mm. And on the other hand, section rolls with micro sections where the section is ground using CNC contour cutting at a special profile grinding machine with up to 11 controlled axes. In this case, contour accuracies of less than 5 µm can be achieved – the smallest corner radius is 0.05 mm in an internal corner. Our 3-dimensional measuring machine or a contourograph are used to check the profiles. Guaranteed concentricity precision of 1 µm and finest surface finishes are standard features. The section rolls are available in solid metal and tool steel and as a hard metal coated version. And it goes without saying that we can also produce our rolls using special materials, such as ceramic. As part of our roll services, we offer an extensive and efficient range of repair, reworking and regrinding services. You can also benefit from our collection and delivery service.
