A grinding machine includes a main spindle on which a grinding wheel is mounted, a spindle head movable relative to a workpiece, a dressing device body provided to be movable relative to the spindle head and a dresser supporting member provided to be movable relative to the dressing device body for rotatably supporting a dresser. The dressing device body is moved to a dressing position while the grinding machine grinds with continuous dressing. The dressing device body is moved to a retracted position while the grinding machine normally grinds except for the grinding with continuous dressing.
