This is a common method employed for the finishing work of steel. This requires very skilled workers who can repeat continuously a restricted grade of surface finish to fine geometric tolerances. Here machines and tools used should have very good condition with all the ways and guides straight, erect and true and attention should be given for the balancing of the wheels. The most important thing here is wheel surface preparation. Tolerable flow of chip and granule free coolant is essential here. The choice of wheel grit, speeds coolants will vary with the material being cut and the finish demanded.
