The cylindrical grinder is a type of grinding machine used to shape the outside of an object. The cylindrical grinder can work on a variety of shapes, however the object must have a central axis of rotation. This includes but is not limited to such shapes as a cylinder, an ellipse, a cam, or a crankshaft. A cylindrical grinder.
where D r and N r are respectively the diameter in mm and rotational speed in rev/min of the regulating roll. The setup of a typical internal centerless grinding machine is shown in Fig. 49. Instead of a rest blade, a holding roll and a support roll are used to maintain the position of the workpiece. The position of the holding roll.
