ABSTRACT:
A device for grinding the head of a valve, especially of an internal-combustion engine, has a rigid stand, a structure for supporting the valve stem in terms of rotation that is arranged fixedly and vertically on the stand, a stop for rotational bearing against the valve tail, and a drive mechanism for driving the valve in rotation by the front face. The drive mechanism is arranged vertically below the structure for supporting the valve stem in terms of rotation with a coupling to compensate for any misalignment between the axis of rotation of the drive mechanism and the axis of rotation of the valve stem. A machining station is mounted on the stand having a machining tool mounted thereto in an orientable manner so that the machining axis may be adjusted in relation to the fixed and vertical reference system of the valve stem.
