Abstract:
An apparatus for machining a workpiece comprising:a bed, a headstock disposed on the bed and arranged and constructed to rotatably support a first end of the workpiece, wherein at least one of the headstock or the tailstock is slidably disposed on the bed so as to permit adjustment of the distance between the headstock and the tailstock, a carriage disposed on the bed between the headstock and the tailstock and arranged and constructed to move in a direction of Z-axis along a longitudinal axis of the supported workpiece, a lathe tool operably and slidably disposed on the carriage, a hob operably and slidably disposed on the carriage, wherein the lathe tool and the hob are arranged and constructed to move on the carriage in a direction of X-axis that is generally perpendicular to the Z-axis so that one of the hob and the lathe tool can selectively engage the workpiece without interference of the other of the hob and the lathe tool that is not performing a machining operation, and wherein the hob is rotatable about the X-axis and is movable in a direction of Y-axis that is perpendicular to the Z-axis and the X-axis.
