"Wheel lathes" are designed to machine the wheel and axle assemblies from railway locomotives and rolling stock. Deutschland Dortmund offered several types, some with fixed headstock and tailstocks for workshops handling just one gauge to others adaptable to machine a number of widths and diameters. Four distinct types were offered, all with an electrically-driven centering mechanism: the multi-purpose DRK able to handle both rolling stock and locomotive wheels, wheel tyres and centres; the DRG for locomotive wheels only when mounted with their internal bearings, coupling pins and cranks (and a sub group, the DGRE for wheel sets from electric engines fitted with external axle journals); the DRP with "pendulum friction" drivers used only for outside axle journals fitted with plain bearings and the DRL, a "high production" type with pneumatically-operated clamping devices and designed to hold wheel sets from rolling stock including those fitted with anti-friction bearings complete with their bearing casings..

Type DRL-110 wheel lathe with a 1100 mm swing and taking 1000 mm between centres (43" x 3' 3") to take 1 metre gauge car wheels (rolling stock only) with pneumatically-operated camping and fixed headstock and tailstock. Fitted with a 4-pole speed-change motor  running at 500, 750, 1000 and 1500 r.p.m.

Type DRK-1V-110 wheel lathe with a 1100 mm swing and taking either 900 or 1680 mm between centres (43" x 3' or 5' 6"). A multi-purpose railway wheel lathe with four ways that could take various gauges with the toolposts and tailstock being moveable. Note the ratchet-type power-feed arrangements, a common arrangement on this class of Deutschland Dortmund machine

Four examples of the Type DRK-1V-110 wheel lathe with four ways viewed from the roughing toolpost (tailstock-end) side. Note the metal sheets covering the beds where tailstock moves and the automatic clamping motor sticking out horizontally from the tailstock

Type DRL-110 a "high-production" wheel lathe with a swing of 1100 mm and admitting 1000 mm between centres. This lathe had what the makers called "pendulum friction" drivers and was intended only for railway wheel sets with "free axel" journals. The headstock and tailstock were fixed to "broad gauge" standard. The motor fitted was a 4-pole speed-change type running at 500, 750, 1000 and 1500 r.p.m.

The huge DRG-230 wheel lathe with a 2300 mm swing and 1435 mm between centres (91" x 4' 8.5"). Intended for the machining of large locomotive driving wheels with or without the cranks in place
