hDD-Technology

Hybrid technology (hybrid Diamond Dresser) makes it possible to synthesise a unique structure within the active dressing tool rim. The porous base matrix achieves a free-cutting structure which enhances the abrasive wheel's stock-removal capability in dressing operations.

A dressing tool based on hybrid technology also exhibits exceptional wear resistance. This is achieved by a selected combination of metal and ceramic properties in the matrix of the dressing coating.

Today, hDD tools are used in large-scale production processes both as dressing cups on small turbines and as dressing discs with internal or external diamond rims up to 420 mm in diameter, or as stationary dressers.

System characteristics

  • No ancillary times / only small ancillary times for resharpening the dressing tool
  • Significantly improved geometry of the ground components
  • Better surface quality of the workpiece due to optimum cutting ability of the grinding tool
  • No running-in period after dressing
