Roller Burnishing

Mollart Roller Burnishing

Mollart roller burnishing equipment provides chipless machining and cold working of surfaces to create high specification surface finishes, eliminating the grinding process.

Internal & external multi-roll tools along with carbide roll tools for ID and OD profiling of parts on CNC machines.

Mollart multi-burnishing tools are designed for burnishing shafts, faces tapers, contours, and IDs greater than 70mm.


Ecoroll deep rolling and combined skive-burnishing tooling

Ecoroll roller burnishing, deep rolling and combined skive-burnishing tooling can be applied to blind or through bores, stepped bores as well as inner and outer surfaces.  A heavy duty range of skiving heads is available for opening larger tube bores providing combined boring with burnished surfaces.
