The goal is to keep stainless steel as cool as possible throughout the process. To that endit helps to choose a grinding wheel with the fastest removal rate possible for the application and budget. Wheels with zirconia grains grind faster than aluminum oxidebut in most cases a ceramic grinding
Aug 272019 Traditionallymany manufacturers may be satisfied with savings slightly over 10%but there is still room for improvement to optimize the grinding process. When grinding with lower powerincreasing the feed rates to push the wheel back up to the same power as the original wheel may reduce cycle time further.
The term grinding burn while grinding is understood as the thermal damage of a ground part caused by an incorrect grinding process. Grinding burn is caused by excessive heat dissipation into the part material. As materials cool as rapidly as they heatthe material undergoes a treatment similar to a tempering process.
