Multi-roller burnishing: Impressive advantages

Surface roughnesses of under Rz 1µm, short cycle times and low investments with fast amortization make chipless multi-roller burnishing a high-quality, cost effective alternative to any cutting process. In addition, the results achieved with multi-roller burnishing are impressive thanks to

  • hardened boundary layers
  • increased fatigue strength
  • larger contact area ratios due to plateau formation
  • greater surface resistance to wearing and corrosion
  • shifting of the material fatigue Limits
  • reduction of coefficients of sliding friction
  • environmental friendliness due to a lack of waste products.


Multi-roller burnishing tools: „sprinting“ to extreme smoothness

The best surface quality fast – that‘s a main characteristic of Baublies multi-roller burnishing tools. Depending on the roller burnishing task various numbers of hardened rollers are arranged in a cage. The machining times are kept short by using several rollers simultaneously. During roller burnishing with multi-roller tools, a roll-off process with kinematics similar to those of a planetary gear results. 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.


Diversity for any machining task

Baublies multi-roller burnishing tools are available as standard tools for an extremely broad range of interior and exterior applications. An unlimited number of special solutions optimally round off the product line and open up roller burnishing for an increasing number of new applications.


Multi-roller tools are worth the investment, as they...

  • equire very short machining times
  • realize outstanding surface qualities
  • do not subject the workpiece to lateral Forces.
