Abstract
A thread grinding machine comprising a headstock movable to-and-fro upon a machine frame. This to-and-fro movement is generated by a threaded rod driven by a spindle and transmission means and a rod member pivotably mounted at one end in a fixed adjustment arm of the headstock and at the other end guided to be axially and pivotably movable at the threaded rod. The rod member is also guided to be axially displaceable in a guide element pivotably mounted in a bearing block adjustably connected with the machine frame. A control device reverses the direction of rotation of the driven spindle.
