ABSTRACT:
The part (1) to be machined, which exhibits an axis of revolution (aa') is secured in a rotatable spindle (11) forming part of a headstock (10) movable in translation on the framework of the grinding machine according to a longitudinal axis (X) parallel to the axis of revolution (aa'). A support (16) fixed to the framework and in the immediate proximity of which is arranged a grindstone (18), serves as lateral support to a portion of the part (1) to be machined. Grinding of the part (1) by the grindstone (18) over an arbitrary length capable of exceeding 1000 times its diameter, is effected by displacing the headstock (10) by such length in the sense of the longitudinal axis (X).
