ABSTRACT:
A quill feed and spindle drive assembly has a bore formed along a longitudinal axis of a housing. A nut, rotatably mounted to the housing, carries a threaded quill which reciprocates along the axis through the housing. An elongate rotatable spindle passes through the bore and carries a tool at an outer end. The threaded quill is preferably a hollow screw, within which the spindle is mounted, and the quill and spindle are coextensive and linearly moved in unison along the axis. The quill provides both radial and axial thrust support, and forms a longitudinal guideway for the tool.
