Abstract (en)

[origin: US4386483A] Two grinding-wheel spindles bearing grinding wheels are mounted on a table which undergoes an angular displacement for simultaneously grinding convergent internal and external conical surfaces of a workpiece, on the one hand, and for truing the grinding wheels by means of truing tools, on the other hand. The truing tools are so positioned that the grinding faces of the wheels are trued in a manner whereby the workpiece surfaces are then automatically ground with extreme precision and the exact desired diameter of the circular edge formed at the junction of the convergent surfaces is obtained.
