ABSTRACT:
A steady is coupled to a longitudinal slide and comprises a driven chuck. A milling tool is carried by a tool slide, which is slidably mounted on the longitudinal slide for a transverse movement derived from the rotation of the workpiece. To prevent a sagging or twisting of the workpiece or inaccuracies resulting from thermal expansion and also to eliminate the need for complicated driven chucks in workpiece carriers and to enable a milling of cross-sections to very close tolerances, two workpiece carriers are provided with non-driven workpiece supports whereas drive means for rotating the workpiece are associated only with the chuck of the steady. The control of the transverse movement of the tool slide is derived from the rotation of the chuck or of the means for rotating the same.
