Grinding and Polishing Guide Buehler

Wet grinding minimizes specimen heating, and prevents the abrasive surface from becoming loaded with metal removed from the specimen being prepared. Each grinding step, while producing damage itself, must remove the damage from the previous step. The depth of damage decreases with the abrasive size but so does the metal removal rate.

Factors affecting proper coolant application when

2017-8-11  Grinding is a thermally dominated process, meaning a high percentage of process heat initially enters the part before coolant quenches it. Unless the coolant is applied at the correct flow rate and pressure, and the proper input conditions are selected, this process can lead to undesirable rehardening burn, thermal softening and tensile residual stresses.
