NaShaft Eco

To support shaft typed parts for the production of specificroughness topographies and optimum geometry values.


Superfinishing processes can be integrated into this highly flexible machine concept;they can be used to increase the resilience of running surfaces for slide and roller bearings as well as to produce high-precision sealing seats on shaft typed parts.

  • Superfinishing with tape: A superfinishing tape is used as a tool that combines ground shoes or pressure rollers with different hardness properties or our patented dFlex 2.0 universal finishing shoe
  • Superfinishing with stone: A high-performance superfinishing stone is used as a tool, with a grain size and bond specifically designed forthe application.
  • The removal of the material is achieved through the rotation of the workpiece VW, the pressing force Fn, and theshort-stroke oscillation Fosz working in parallel with the workpiece axis.
  • Auxiliary functions on the NaShaft Eco machine platform often include the integration of additional brush deburringprocesses for defined edge rounding or the realisation of polishing operations for the production of high-glosssurfaces.
