Before being launched on the market, each batch of superabrasive is carefully submitted to a battery of tests in the laboratory which is certified ISO 9002.

The following physical properties are carefully tested and analyzed:

  • size distribution average
  • size standard deviation
  • shape factor
  • shape standard deviation
  • eccentricity (computed optical analysis)
  • strength (Toughness Index)
  • microshipping resistance
  • wear resistance
  • strength after heat treatment (Thermal Toughness Index)
  • microchipping resistance after heat treatment
  • thermal stability (based on the weight loss and the TTI/TI ratio)

For each batch, all test results of the above characteristics are computed and, through a mathematical model, a Performance Index is defined.
