Many changes have taken place in the grinding wheels to fulfill these needs. Grains: Aluminium Oxide and Silicon Carbide were used in the conventional grains. Now in their place, ceramic grains have been developed. New ceramic grades like Seeded Gel (SG), Targa Gel (TG), Norton Quantum (NQ), Cubitron (CU) are now in use.

Creep-feed grinding (CFG) was a grinding process which was invented in Germany in the late 1950s by Edmund and Gerhard Lang. Normal grinding is used primarily to finish surfaces. But CFG is used for high rates of material removal, competing with milling and turning as a manufacturing process choice.

Ceratizit When faced with a unique part geometry or feature for which no standard cutting tool is available, machinists sometimes braze chunks of carbide together then manually grind the piece to the desired shape. When finished, these ad hoc milling, drilling, and boring tools often look like Frankenstein's monster.
