Claim:
1. A machine tool, comprising: a machine base; a first support provided on a first rotational machine axis, the first rotational machine axis being rigidly mounted on the base in an immovably fixed position relative to the base and comprising a first drive operable to rotate the first support about a first axis of rotation; a second support provided on a second rotational machine axis, the second rotational machine axis being rigidly mounted on the base in an immovably fixed position relative to the base and comprising a second drive operable to rotate the second support about a second axis of rotation, a control arrangement configured to control the orientation of the first support about the first axis of rotation of the first rotational machine axis, the orientation of the mount about the second axis of rotation of the second rotational axis and a location of the mount along the first linear axis of the first linear machine axis, using the first, second and third drives, respectively, so as to govern the position and orientation of the first support and the mount relative to each other, to rotate the one of the first support and the mount such that the rotational axis of the grinding wheel is non-parallel with respect to the longitudinal axis of the workpiece, and to grind the workpiece with the grinding wheel by moving the grinding wheel longitudinally along the workpiece with the rotational axis of the grinding wheel at an angle to the longitudinal axis of the workpiece to form a tapered profile on the workpiece.
