Multi-roller tools are offered in a broad range of standard and special designs. They are used to work cylindrical holes, shafts, tapers and plane surfaces. The advantages of multiple rollers working simultaneously is a fast and economical machining without cross force to the rotation axis. These type of tools are used on all established types of machines.

Depending on the roller burnishing task, several hardened rollers are arranged in the cage. A taper supports the rollers and provides the contact force for forming the material. The rolling diameter is adjusted by axial shifting of the taper relative to the roller. The simultaneous engagement of several rollers results in a short processing time.
