Provided is a grinding machine that does not require work for replacing an upper roller () and a lower roller () and that ensures interchangeability thereof, even when the outer diameter of a workpiece (W) and the inclination state of the generating line of the workpiece (W) are different. A headstock () of the grinding machine comprises an upper-roller device () on which the upper roller () is rotatably supported, and a lower-roller device () on which the lower roller () is rotatably supported. The upper-roller device () and the lower-roller device () are provided with vertical position adjustment mechanisms (), (), respectively, for modifying the height position related to the vertical direction thereof, and a turn angle adjustment mechanism () for modifying the inclination angles of the upper-roller device () and the lower-roller device () with respect to the horizontal direction of the center axes thereof.
