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
