Diamond Vitrified Wheels

APPLICATION AREA FOR VITRIFIED DIAMOND WHEELS

  1. Grinding of carbide parts: puncheons, gauges, rollers and so on
  2. Grinding of carbide drill bits with diamond inserts
  3. Grinding of PCD/PCBN cutting inserts
  4. Co-grinding of carbide and steel
  5. Profiling of CBN wheels

ADVANTAGES OF APPLYING VITRIFIED DIAMOND WHEELS

  • Increased productivity
  • Increased precision and better surface
  • Increased wheel life
