Divisional Research across the Group:


The affiliated laboratories of SAINT-GOBAIN are working continuously to improve the properties of each vitrified bond system.

The vitrified bond system N7 is one of the latest developments from WINTER. It offers tremendous advantages in the grinding of crank and cam lobes, journals, flanges and pins.

N7 is characterized by the following features:

  • best wetting of the abrasives
  • excellent shaping of the bond bridges
  • very high bond hardness
  • very high wear resistance

The N7 bond can be adapted to suit the specific grinding process and component material by variation in:

  • Grit type
  • Grit size
  • Structure
  • Porosity 
  • Hardness
  • Concentration
