Processes

The basic principles of roller burnishing
Roller burnishing is a process for microfinishing metallic surfaces which belongs to the forming processes When roller burnishing, a rolling body, usually a roller or ball is pressed onto the surface and rolled over it. By this means a high compressive stress is created in the surface finish peaks which induces the material to flow.

 

The basic principles of deep rolling
When deep rolling, a rolling element, which can be a ball as well as a roller, is pressed against the surface of the work piece. The compression in the contact area exceeds the yield point and a plastic forming takes place in the boundary layer.

 

Skiving/roller burnishing
Combined manufacturing process to produce hydraulic cylinders and cylinder tubes.

 

The basic principles of mechanical hammer peening
MHP is a powerful, incremental mechanical process and belongs to the group of direct-acting processes.
