Advantages of Grinding Process

Size of abrasive materials works a very important role in grinding process. Larger size grains

will remove material faster from workpiece surface but did not provide the better surface finish.

Whereas smaller grain size will remove material slowly from workpiece surface with better surface

finish. These grains of abrasive material are termed as grits. Grits will have sharp edges or sharp points with enough hardness as compared to workpiece surface. Grits also have higher and wear resistance

compared to workpiece surface. These grits will act as cutting tool in process of grinding to remove

small particles from workpiece surface. According to society of manufacturing engineers, surface

finishing and precision obtained from a grinding process will be approximate ten times better as

compared to machining process performed by milling or turning.

Performance of grinding wheel will be dependent on grain size, pore structure and bond type.

Service life of grinding wheel will also depend on the application of coolant. Application of coolant in grinding process will reduce the power requirement of grinding machine as well as will provide the

better quality of grinding also.

Advantage of grinding process

On its surface, grinding process seems simple but there are many variations, approaches, and

considerations for this type of machining; each of which is particularly effective for certain applications

with certain materials. Although the grinding process as much a cutting action as drilling, milling, and

lathe turning, there are some reasons for grinding process to be chose as the removal process of

material;

i. Can machine too hard material economically ii. grinding can produce flatness tolerances of less than +/-0.0025 mm.

iii. machining removes excessive material.
