Abstract: A bar feed assembly for receiving and guiding a bar stock to be machined in a lathe, comprises a tubular member for rotatably receiving and guiding the bar stock to be machined and a member for advancing the bar stock through the tubular members. A plurality of stabilizing bodies are provided along said tubular member in spaced apart relation and each has a compliant surface disposed in surrounding relation to the tubular member in a manner which permits axial thermal growth of the tubular members through the stabilizing bodies.

Abstract: A two slide multiple axis machine comprising a machine tool bed having at least two parallel, spaced apart, longitudinal ways; a spindle mount fixedly attached to the bed; a rotateable spindle mounted in the spindle mount at a distance from the bed and having an axis of rotation parallel to the axis of the ways and adapted for receiving and detachably holding a work piece; first tool means engageable with said work piece and displaceably mounted for forward and rearward motion in the first of said ways parallel to the longitudinal axis of said ways; second tool means engageable with said work piece and displaceably mounted for forward and rearward motion in the second of said ways; first way cover means covering the first of said ways and fixedly attached to said first tool means and adapted for movement with said first tool means; and, second way cover means fixedly attached to said second tool means and adapted for movement with said second tool means is disclosed.
