Multi-tool lathe Type D200 x 900 fitted with a special tailstock (Type Bo) for drilling and boring and an automatic cross-feed assembly (Type Pa). The arrangement was intended to allow the lathe to take the place of chucking automatics on heavy work. The picture shows a forged steel cluster-gear 213 mm in diameter and 120 mm long being turned, bored and faced simultaneously in 9.8 minutes.

A "pot chuck" and roller steady being used to hold a four-throw crankshaft. Time taken to machine the centre bearing and both ends was 32 minutes

Turning the crankpins of a two-throw crankshaft using a "pot Chuck". The time for roughing and finishing this 50 mm diameter by 65 mm long job was 12 minutes

Turning a 4-cylinder crankshaft from a solid billet 180 mm in diameter and 750 mm long. This lathe is fitted with an attachment (Type Kpz) that gave a quick return of the cuttings tools mounted on the longitudinal slide

Turning a heavy Diesel engine piston 280 mm in diameter and 530 mm long. Two cross slides and two longitudinal slides are in use - the latter pair arranged so that the right-hand unit taper turns while that to the left turns cylindrically. Time for both roughing and finishing 18 minutes

Turning the inner and out rings of a 150 mm diameter 35 mm wide ball bearing. The ring is held on an expanding mandrel actuated by a lever with the longitudinal and cross slides doing the roughing and finishing in one setting: time 1.5 minutes.

Turning push rods from an automobile gearbox. Made from 19 x 19 mm square bar the rods were 320 mm long and supported by a travelling roller steady. Machining time 4.5 minutes.

Production lathe Type F200. First exported to America, this lathe was designed for turning small quantities of repetition work that could not be done economically on a multi-tool lathe - or for work which, owing to its shape, did not allow the longitudinal and cross slides of such a lathe to work simultaneously. The makers reported that customers had employed the F200 for the manufacture of belt pulleys, multi-step cone pulley, changewheel blanks, bearings, bolts, plain and armature shafts, pistons and crankshafts, etc. It was also suggested that work started on a capstan or semi-automatic lathe could be finished to a high degree of accuracy by being mounted been centres on an expanding mandrel.
