Claims
- 1. A lathe comprising:
a base; a driven main spindle mounted to the base; a first tool turret rail assembly mounted to the base generally parallel to a z axis of the base; a first tool turret assembly movably mounted on the turret tool rail assembly for movement along the z-axis; a secondary spindle rail assembly separate from the tool turret rail assembly mounted to the base generally parallel to the z axis of the base; and a secondary spindle movably mounted on the secondary spindle rail assembly for movement along the z-axis.
- 2. A lathe as in claim 1 and further comprising:
a second tool turret assembly mounted to the base.
- 3. A lathe as in claim 2, wherein the second tool turret assembly is movably mounted to a second tool turret rail assembly mounted to the base.
- 4. A lathe as in claim 1, wherein the base includes a vibration-damping substance attached to the base for decreasing vibrations in the lathe.
- 5. A lathe as in claim 4, wherein the vibration-damping substance is cast into a cavity in the base.
- 6. A lathe as in claim 4, wherein the vibration-damping substance is mounted in a cavity in the base.
- 7. A lathe as in claim 1, wherein the base is constructed of a polymer composite.
- 8. A lathe as in claim 4, wherein the base is constructed of a polymer composite.
- 9. A lathe as in claim 4, wherein the base is constructed of metal.
- 10. A lathe as in claim 1, wherein the first tool turret rail assembly and the secondary spindle rail assembly are offset from each other along an x axis of the lathe.
- 11. A lathe as in claim 10, wherein a portion of the first tool turret rail assembly interstitially overlaps with a portion of the secondary spindle rail assembly.
- 12. A lathe as in claim 11, wherein the first tool turret rail assembly includes two parallel rails and the secondary spindle rail assembly includes two parallel rails.
- 13. A lathe as in claim 1, wherein the secondary spindle is driven.
- 14. A lathe as in claim 1, wherein the first tool turret assembly is constructed and arranged to machine a workpiece mounted to the main spindle and a workpiece mounted to the secondary spindle.
- 15. A lathe as in claim 1, wherein the second tool turret assembly is constructed and arranged to machine a workpiece mounted to the main spindle and a workpiece mounted to the secondary spindle.
