ABSTRACT:
A portable lathe (10) for machining precise conical surfaces on a fixed workpiece (42) using rotating inclined cutter bits (38) driven by air motors (16, 18) through drive shafts (64, 66), worm gears (68, 70), a ring gear (60) and a carrier shaft (52) that is axially movable towards and away from the workpiece under control of a feed control handwheel (78). Exhaust air with entrained lubricant from the drive motors cools and lubricates the interior of the lathe and blows chips out of the housing (12) through observation openings (86). Axial projections (48) are keyed to a workpiece (43) during a machining operation to prevent relative rotation between the workpiece, which is accurately located relative to the cutter bits by a conical guide (47) in the open end of the housing.
