Technical info - grinding wheels
Grinding wheel grain size
Standardised mesh size per inch when sieving the abrasive grain. A large mesh size gives coarse grain, a tight mesh results in fine grain.
Grinding wheel grain size, classification | |||
---|---|---|---|
coarse | medium | fine | very fine |
12 | 30 | 80 | 180 |
14 | 36 | 90 | 220 |
16 | 46 | 100 | 240 |
20 | 54 | 120 | 280 |
24 | 60 | 150 | 320 |
Grinding wheel hardness
Resistance to the abrasive grain breaking away. Depends on the amount of binder. The strength of the grinding wheel is also determined by the grain size.

Technical info - Grinding INOX/NIRO/stainless steel
Abrasives for INOX/NIRO/stainless steel must be free of iron to prevent subsequent corrosion due to extraneous rust.
- Use non-ferrous corundum abrasive discs and belts and use only for INOX/NIRO/stainless steel
- If possible, use the grinder only for INOX/NIRO/stainless steel
Surface treatment of INOX/NIRO/stainless steel on belt grinders:
- post-processing of welds with abrasive belt grit 40
- Fine grinding of surfaces with successive grinding belts grain size 80-100-120, or even finer, depending on the desired finish
- Keep grinding belt speed below 40 m/s to prevent overheating and tarnishing; rework tarnished areas to avoid corrosion.
- Wet grinding: Best finish with coolants and grinding oil; the same grinding belt grain results in a finer surface with wet grinding
