摘要:
A C-axis driving system for machine tools is disclosed that comprises a worm wheel mounted on a spindle that is rotatably supported by a headstock. The C-axis driving system also includes a worm shaft with a worm formed therein directed perpendicular to an axis of the spindle and placed so as to be pivotable about a pivotal shaft between an engagement position, and a disengagement position. The C-axis driving system also includes a C-axis driving motor connected to the worm shaft and serving to rotationally index the spindle to a specified rotational angle. The pivotal shaft is provided on the worm shaft base so as to be directed perpendicular to an axis of the worm shaft. Thus, the C-axis driving system for machine tools is capable of reducing the size of the C-axis unit as well as the cost while allowing a smooth engagement with the worm wheel.
