ABSTRACT:
A grinding machine that can continuously grind a rod-like object rotating around its axis supported by a head and a tailstock. Grinding tools are attached to a rotating circular plate which is provided on a carriage that moves along a bed adjacent the axis of the rod-like object at a constant rate to grind the outer surface of the rod-like object. The circular plate includes a front side on which a plurality of first and second grinding tools are mounted. The grinding tools include those for roughing and those for finishing and are mounted along imaginary circles of different radii according to their use in grinding. The plate can be moved up and down so that the rod-like object can be ground with the pertinent tools. That is, a different degree of grinding ranging from roughing to finishing can be performed with different tools in a continuous manner by only changing the height of the circular plate without exchanging the tools.
