The choice is yours
Thread rolling is the core expertise of Eichenberger Gewinde AG. Not surpris-ingly, the Company utilizes this process to form the thread profiles of all the screws it makes. Thread rolling (often also referred to as thread milling) is the cold forming of the surface of round workpieces. The thread form is produced by causing a ra-dial dynamic force to be exerted between the two rotating rolling dies that form the workpiece. As the roll die profile penetrates the workpiece surface, the material in cold state is pressed all the way down into the root diameter of the thread roll die and is therefore rolled according to nominal value.Advantages of thread rolling:– significant increase in hardness through cold forming – excellent surface smoothness on thread flanks and in ground radius – reduced notch sensitivity – no interrrupted swalfe as in machine- ground threads – excellent dimensional accuracy – rational manufacturing process – extremely cost-effective especially in large production batchesEven though all Eichenberger lead screws are made using the rational thread rolling process, individual model series feature distinct differences in design and perform- ance. Product characteristics therefore need to be considered when selecting the right product.Basic differences are shown in the summary description (opposite). Eichenberger Threads
