Saint-Gobain Abrasives  

• Has over 13 years of manufacturing quality Vitrified CBN Wheels. 

• Is registered under BSI (certificate FM 14090) BS EN ISO 9001:1994

• Service gives product engineers with considerable field experience both in the UK and abroad.

• Research and Development facility ensures the latest technology is incorporated into wheel design. bond formulation and manufacturing techniques

• Vitrified wheels are second only to diamond in hardness, with twice the hardness and 4 times the abrasion resistance of conventional aluminium oxide wheels. 

• Vitrified wheels utilise a high temperature ceramic bond which is thermally stable at up to 1000 °C.

The Advantages

• REDUCES OVERALL GRINDING CYCLE TIMES

  The longer dress intervals and high speed grinding capability of Vitrified CBN wheels enable reductions in floor to floor times.

   

• EXCELLENT FREE CUTTING ABILITY AND GRINDING EFFICIENCY

  The porosity of Vitrified CBN wheels reduces grinding resistance and gives good chip clearance.

   

• GOOD TRUING AND DRESSING ABILITY

  The selection of porosity and bond allows truing and dressing to be carried out efficiently

   

• LONG LIFE

  High Bond strength means that dressing intervals are extended

   

• CONDITIONING

  Modifying the dressing parameters enables variation in surface finish

   

• HIGH PRECISION

  Vitrified bond CBN wheels are able to grind to tight tolerances

   

• SOLVES GRINDING PROBLEMS

  The CBN Grit and Vitrified bond are an excellent combination on normally difficult to grind materials

   

• IDEAL IN HIGH VOLUME PRODUCTION GRINDING

  The long life and grinding performance of Vitrified CBN wheels are well suited to automated / CNC production systems

   

• BETTER QUALITY PARTS

  The cool cutting characteristics of Vitrified CBN can impart compressive stresses into the work piece.
