A cylindrical grinder (10) includes a workpiece support section (20) adapted to support a generally cylindrical workpiece (W) and rotate the workpiece (W) about a rotational axis, and a wheel head (31) adapted to support and rotate a grinding wheel (T). The wheel head (31) is moved relative to the workpiece support section (20), along a first direction parallel to a rotational axis of the workpiece (W) and along a second direction perpendicular to the first direction in order to grind an outer surface of the workpiece (W). The wheel head (31) is turnable relative to the workpiece so that a rotational axis of the grinding wheel can be tilted within a plane substantially passing through the rotational axis (Ts) of the grinding wheel (T) and the rotational axis (Ws) of the workpiece (W), within a range extending across a reference plane perpendicular to the rotational (Ws) axis of the workpiece (W). Further, link-type parallel link mechanisms (200) for moving the grinding wheel (T) are disclosed. IMAGE
