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
