Abstract
Disclosed is a numerically controlled grinding machine for grinding a tapered surface of a workpiece. In the grinding machine, a workpiece having a tapered portion and a reference end surface is supported on a traverse table in such a way that the workpiece is rotatable about an axis intersecting the Z-axis at a predetermined angle, which is equal to an angle formed between the tapered surface and the rotational axis of the workpiece. In addition, a measuring device for measuring the position of the reference surface is mounted on the wheel head.
