With thread rolling, profile rolling and smoothing, we offer you non-cutting forming processes for the production of precise threads and profiles and for improving surface quality. These processes ensure high dimensional accuracy, strength and an excellent surface finish - ideal for applications in the automotive, e-bike and mechanical engineering industries.
In thread rolling, the workpiece is positioned between two rotating tools using a 2-roller thread rolling machine. The feed of the rolling carriage causes the tools to penetrate the material and transfer their profile directly to the component. This process takes place without material removal, which compacts the surface and increases the strength of the workpiece.
Advantages of thread rolling: - Chipless forming without material loss
- Higher strength due to work hardening
- High surface quality and dimensional accuracy
- Longer component service life
- Short processing times
For short thread dimensions, we use plunge rolling, in which the rolling tools simultaneously penetrate the material and form the thread in a single operation.
The rolling force depends on the following parameters: - Material strength
- Degree of deformation
- Thread pitch
- Contact surface of the tools
Smoothing - perfect surface quality In order to achieve excellent surface quality and dimensional accuracy, we also offer non-cutting smoothing. In this process, functional surfaces are machined using pressure tools, the surface is compacted and unevenness is smoothed.
Advantages of smoothing: - Surface roughness up to Rz < 1 μm
- Increased wear resistance
- Improved dimensional accuracy
- Increase in component strength
- No material removal
By combining rolling and smoothing, we offer you a cost-effective solution for producing high-precision components with the best surface quality.
