A horizontal bed turret lathe including a slant carriage adapted to achieve the advantages of a slant bed configuration while avoiding the disadvantages thereof. The slant carriage is mounted on a pair of horizontal bed ways offset to the rear of the spindle axis, and includes a pair of inclined slide ways for supporting a tool slide. A turret mounted on the tool slide has a pair of toolholders arranged in stacked configuration on the turret axis. For reducing interference from non-working tools and the turret assembly itself, the turret axis is skewed with respect to the spindle axis. To compensate for the skew of the turret axis, the toolholders are frusto-conical in shape, the degree of conical taper allowing each tool to be indexed to a normal operative position. An orderly tool arrangement is achieved by mounting end working tools in the upper toolholder and turning tools in the lower toolholder, the overall configuration allowing both end working and turning tools to operate up to the face of the chuck. Additionally, a tailstock may be conveniently provided on a pair of auxiliary ways, the overall configuration minimizing interference from the tailstock. The slant carriage is further stabilized by folding the slide drive and slide counterbalance assembly back into the carriage thereby lowering its center of gravity. |
