Instructions for the use of Diamond and CBN Grinding Wheels
1. To make diamond and CBN grinding wheels fully utilize their excellent characteristics, it is important to pay attention to the following when using them:
a. Mechanical aspects: (1) Precise spindle (2) Good machine rigidity (3) Sufficient working horsepower (4) Stable rotation speed and propulsion speed
b. Grinding wheel installation: (1) The grinding wheel hole and the mechanical mandrel fit H6 (2) The beam swing within 0.01mm, and the face out is within 0.02mm (3) Perfect roundness
2. Dressing and truing:
Truing:
Shape the grinding surface of the grinding wheel to the required form and make it concentric with the center shaft of the grinding wheel.
Dressing:
Smooth the surface of the grinding wheel, remove the binder surrounding the abrasive particles, so that the sharp edges of the abrasive can be appropriately exposed on the surface of the grinding wheel, thereby generating grinding ability.
3. Recommended use of correction and sharpening:
| Wheel Type | Truing | Dressing | |
| Diamond | Resin bonding method(B) | Brake or power slewing dresser | Special sharpening rod for diamond grinding wheels |
| Mild or molybdenum steel | |||
| Porcelain sintering method(V) | Diamond dressing knife (single stone or metal combined dressing knife) | Diamond dressing knife (single stone or metal combined dressing knife) | |
| Metal bonding method(M) | Brake or power slewing dresser | Diamond grinding wheel special sharpening rod | |
| CBN | Resin bonding method(B) | Metal bonded diamond knife dresser | CBN grinding wheel special sharpening rod |
| Mild or molybdenum steel | |||
| Brake or power slewing dresser | |||
| Porcelain sintering method(V) | Diamond dressing knife (single stone or metal combined dressing knife) | Diamond dressing knife (single stone or metal combined dressing knife) | |
| Metal bonding method(M) | Silicon carbide grinding wheel | Silicon carbide grinding wheel | |
| Brake or power slewing dresser | |||
4. Grinding fluid:
wet grinding is preferrable (if not possible, add spraying or air blowing). The grinding fluid has a significant impact on the roughness of the grinding surface, surface accuracy, sharpness of the grinding wheel, and the lifespan of the grinding wheel.
5. Ideal in-feed rate:
| Grinding Wheel Grit Size | Ideal in-feed rate |
| #80~120 | within 0.03mm |
| #140~200 | within 0.02mm |
| #230~270 | within 0.01mm |
| #325~ | within 0.005mm |
