ABSTRACT:
The grinding machine essentially comprises a frame on which a grinding-wheel slide is capable of moving towards a workpiece carried by a sliding table designed in two separate parts or table components, one of which is adapted to carry a headstock while the other carries a tailstock. The two table components are provided with means for controlling their movements in opposite directions and the tailstock table component is subjected to the action of a restoring spring for urging it towards the headstock table component.
