Grinding of sub-micron-grade WC-Co with good lubrication exhibits peculiar 'size effect' behavior more similar to brittle materials. Higher wheel speeds can be detrimental if the coolant velocity is not also increased. Grinding WC-Co at low aggressiveness values leads to temperature-induced resin deterioration.
