Mehta Abstract: All over the India, most of the processing industries are involved with rolling operations for steel and alloyed materials. To perform these operations, rolling mills are used. But maintenance of such rolling mills is a tedious job, because these rolling mills work

Ball End Mills | McMaster-Carr

Fast-Cutting Carbide Ball End Mills. Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life. Made of solid carbide, they are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material.Machinery Vibration Limits#8,pumps, compressors, pulp refiners, ball mills, furnaces and piping systems.
