Grinding vs Machining: What's the difference?
Grinding process needs a grinding wheel to remove material. The grinding wheels are made of sharp abrasive grains (ceramic, alumina, zirconia, silica, etc.) Machining process requires a cutting tool (sharp edge cutter) to remove material. This cutting tool is made of hard metal, ceramic, and diamond. Product Specification.

Grinding Machining Process : Complete Notes
This process is known as Dressing of grinding wheel and the whole process takes 15 to 20 minutes to operate. The life of the grinding wheel is described as the time period between two successive dressings. Grinding operation is one of the machining processes which consume the highest specific cutting energy with very less material removal rate.
