Cylindrical grinding is the process of grinding the outside surfaces of a cylinder. These surfaces may be straight, tapered or contoured. Cylindrical grinding operations resemble latheturning operations. They replace the lathe when the workpiece is hardened or when extreme accuracy and superior finish are required.
