Abstract: Provided is a cylindrical grinder that is capable of automatically moving and fixing a tailstock in accordance with variations in length of a workpiece and enables improvement in its productivity. An NC cylindrical grinder includes: a table as a base; a headstock and an NC tailstock both arranged on the table; a moving mechanism configured to move at least either one of the headstock and the tailstock in a Z-axis direction; and a protective cover provided to the table and configured to protect the moving mechanism. In an area between the headstock and the tailstock and at a height position above the protective cover, a tooling base for mounting a tooling instrument thereon is arranged in a freely movable manner in the Z-axis direction. Provided is a guide mechanism for guiding the tooling base in the Z-axis direction and fixing the tooling base to the table at a required position.
