ABSTRACT:
A guide bush is described, having a bush-holder and a quill integral with the bush support. The device has a clamp capable of rotating a workpiece, means for opening and closing the clamp and regulating means adapted to monitor the opening and closing means in order to compensate for changes in the dimensional tolerances of the workpiece, wherein the bush regulating means are adapted to operate the opening and closing means of the clamping means very quickly as a direct result of variations in the dimensional tolerances of the workpiece in order to provide a substantially constant pressure of the clamp on the workpiece. The bush is for use with a machine tool such as a travelling headstock automatic lathe.
