The results of the study proved that grinding IN718 in straight oil gave a 9–10 times improvement in productivity and in wheel life over grinding in water-soluble oil. Testing consisted of grinding slots in IN-718 parts with half-inch wide wheels.
The straight wheel is the most common mode of a wheel that is found on pedestal or bench grinders. This is the one widely used for centreless & cylindrical surface grinding operations. As it is used only on the periphery, it forms a little concave surface on the piece. This is used to gain on several tools like chisels.
