1. A method for grinding a taper surface inclined relative to an axial direction of a workpiece by using a co-axially aligned rotating tapered grindstone, said method comprising the steps of:

  • pressing said grindstone on said taper surface by a controllable pressing force in such a manner that an entire peripheral surface of said taper surface contacts said grindstone and so that the rotational axis of said grindstone and the axis of said taper surface remain in constant alignment;

    rotating said grindstone relative to an entire peripheral surface of said taper surface while pressing an entire peripheral surface of said grindstone on said entire peripheral surface of said taper surface;

    grinding said taper surface by said grindstone; and

    varying said pressing force during said step of grinding to control finished taper surface parameters including circularity of the tapered surface.
