Abstract: Two juxtaposed cross slides provided with toolholders are slidably mounted on the saddle of a lathe. To permit an unrestricted use of lathe tools as well as of boring, drilling and milling tools, each cross slide is movable independently of the other. One of the two cross slides carries a turret on the side which is remote from the other cross slide. Said other cross slide carries a tool head, which comprises a tool spindle, which is adapted to be rotationally driven. That tool head is mounted for angular adjustment on an axis which is at right angles to the tool spindle, to the main axis of the lathe, and to the guide for said other cross slide.

Abstract: A deep boring or drilling mill, especially of the horizontal type, comprises a machine bed. A headstock and a tailsotck are operatively arranged on the machine bed. A cooling medium supply device is operatively arranged between the headstock and the tailstock and participates in or performs a clamping movement. The displacement movements of the headstock and of the cooling medium supply device are synchronized with each other during the clamping phase and during the release phase of these displacement movements. Preferably, the length and speed of the displacement movements are balanced or adjusted by an electrical bridge circuit.

Abstract: Apparatus for externally and internally peeling pipes includes a drill head secured to one end of an elongated drill rod and an external cutter head longitudinally-spaced from the drill head in the direction of movement of a pipe through the apparatus. A feed mechanism is positioned adjacent the drill head for feeding a pipe completely past the drill head and at least partially through the external cutter head. An extraction feed mechanism is positioned on the opposite side of the external cutter head from the drill head for pulling pipes completely past the external cutter head. The feed mechanism adjacent the drill head includes opposed pairs of rollers, one pair of which is radially aligned with the cutters on the drill head.

Abstract: The invention comprises a tool turret for a turning machine whose operational axis has a wider spacing from the bed of the carriage than the spindle axis of the turning machine. The tool turret has an inner rim with inner turning tools and an outer rim with outer turning tools, the inner and outer turning tools being angularly offset in relation to each other. In order to bring the inner and outer turning tools into operating position during the stepwise further movement of the turret, successive operational angles must be variable. Because of the wider spacing of the operational axis from the bed of the carriage, the turret disc carrying the tools can be made larger with the result that more tools can be provided thereon or the spacing between the tools can be enlarged. The changeover with unequal angles can be accomplished by means of a regulated direct current motor, the operational angle being fed into the regulation circuit as the desired value.

Abstract: Carriage attachment apparatus is disclosed for carrying a workpiece on an associated saw table whereby planar surfaces may be formed by sawing with common attachment between the carriage and a woodturning lathe being provided so that the sawed product is turned about the same rotational axis affording a high degree of symmetry.

Abstract: 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.

Abstract: A turning machine with a rotary work spindle and a slide having a lower carriage movable in parallelism with the axis of the spindle, an upper carriage movable on the lower carriage at right angles to the spindle axis, and a tool support on the upper carriage. The tool support is comprised of two indexable turrets, each having a plurality of tools therein, and a common indexing means so that the turrets are indexed simultaneously.
