What are the differences between centerless grinding and external grinding
The fundamental difference between these two ways of grinding cylindrical shapes is how the workpiece is held. In cylindrical grinding it's held on its axis of rotation, "between centers" while in centerless grinding it's supported along its axial length. Centers are precisely ground cones that fit into mirror image recesses drilled in ...Web
