High MRR is desirable in the surface grinding process. It indicates unit amount of material removed for a certain set of parameters. Chips in the form of burrs generated in surface grinding are too small for direct removal from the material surface. It tends to get entrapped in the deep surface valleys and get rewelded due to high temperature.
