Mollart unveils Multi-Surface roller burnishing tool

A carbide roller burnishing tool able to burnish multiple surfaces of a component, including internal and external diameters, radii, counterbores and end faces, as part of a single CNC turning process, is now available through Mollart Engineering. The Multi-Surface boring bar style roll burnishing tool uses a conical, cup-style carbide roll that rotates freely on a precision bearing.

In use, the design is able to accommodate both axial and radial forces generated from the pressure and direction of feed on the component. The tool can even be used directly on pre-ground components that require a burnished texture level of finishing as well as very tight tolerances, says Mollart.

Tools are available to burnish most materials up to 40 HRc from a minimum bore diameter of 16 mm. A selection of roll configurations and shank sizes can be supplied to suit machine and customer applications.
