New Mirror Grinding Super-finishing Wheel “Mr. Neo Lapper”

The Mr. Neo Lapper wheel has an extremely uniform construction that is ideal for mirror finishing and enables consistent polishing without any deposition.
In addition to applying the unique manufacturing method used for the standard Mr. Lapper wheel, the range of grit size produced has been greatly increased.


  • From rough and finish double-layer grinding to single-layer grinding, this newly developed wheel delivers mirror finishing that was previously impossible with standard wheels.
  • A stable finishing surface roughness can be obtained.
