Abstract
A lathe bed includes a steel reinforced concrete body with a torsionally flexible frame and means for rigidly connecting the ends of the frame to the body. The frame includes track members for a tool carrier. In one embodiment, the frame is made of two elongated box-like side members and two transverse column guide members, the side members being fixedly attached as by screws to the concrete body and the column guide members being fixedly attached to the side members. In another embodiment, one side member is used and the two column members extend between the side member and a wall portion of the body at the other end. The body is shaped to permit clearance for turnings removed from a workpiece and for a multiple tool magazine. The headstock, feed drive, longitudinal slides and tailstock are mounted on the frame. The body contributes rigidity to the otherwise torsionally flexible frame to produce a rigid and sturdy unitary lathe bed.
