The Ideal Abrasive?
� Does not exist! Selection depends on:
• Lot size
• Material to be ground

• Process economics
• Surface finish
• Risk of grinding abuse (burning)
• Dressing tool

In this case, the 3 times higher wheel consumption (2 pieces/cycle)of the wheel in the right column is compensated in the overallcosts by the higher feed-rate of 1’600 mm/min.

Cost Calculation Conclusions
The main cost criteria is not the wheel price
Dressing frequency and cycle time are
