All models were equipped with the same design of sophisticated, dual English-metric screwcutting and feeds gearbox, the change from one range to the other being by a single knob. The box also held the gears necessary to reverse the direction of the leadscrew and to change the drive between leadscrew and power-feed shaft. Pitches and feeds were selected by a dial and engaged by a single lever, this arrangement allowing the box to be sealed and lubricated by a pump with oil delivered through pipes.
Module and diametric threads could also be cut, these being obtained by the simple transposing of the mounted changewheels. Pitches not listed on the gearbox plate could be obtained, in the usual way, with additional changewheels - the arrangement of this method being described as "coupling the leadscrew directly to the changewheels", a reference to setting the gearbox lever so as to have a straight-through feed.
For cutting fine pitches, a set of 2 ; 5 ratio gears within the headstock allowed threads with a minimum lead of 0.4 mm to be generated. To protect the drive against damage, a simple shear pin was incorporated in the drive.
Driving through a standard-fit, 12 mm pitch leadscrew - a 0.5-inch pitch was available as an option, as were high-accuracy versions - the screwcutting gearbox (on all models) was able to generate 81 inch pitches from 1/8" to 70 t.p.i.; 67 metric with a lead in mm from 0.4 to 224; 61 module threads from 0.1 to 56 and 81 diametric threads from 1/2 to 280.
Although the screwcutting range was identical across all models, as their work capacity varied, the 32 rates of sliding and surfacing feed were set appropriately, these being (per revolution of the spindle):
E3 and V3: sliding at 0.056 to 2mm (0.0022 to 0.08") and surfacing from 0.025 to 0.9mm (0.001 to 0.035")
E5 and V5: sliding at 0.071 to 2.5mm (0.0028 to 0.1") and surfacing from 0.04 to 1.4 (0.0016 to 0.055").
V6: sliding at 0.15 to 2.65mm (0.006 to 0.1) and surfacing from 0.03 to 0.95mm (0.001 to 0.037").
Doubled-walled of course with all shafts supported at each end, the apron was lubricated by a pressure pump with oil also directed to the bedways and leadscrew clasp nuts; an oil sight-glass was fitted the apron's front face. Engagement of sliding and surfacing feeds was by a single lever working through a drop worm, this mechanism allowing both an instant engage but, more importantly, instant disengage even under the heaviest of cuts. In addition, the apron held mechanisms by which means the cut could be reversed and also a useful automatic disengagement for the longitudinal feed activated by bed-mounted stops. The latter system, besides providing safety against inadvertent damage, meant that an operator, when turning a long job, could safely immerse himself in a copy of a football, motorcycle or girly magazine - surreptitiously held inside an engineering drawing…
Oddly, the 5-spoke carriage handwheel was not fitted with a micrometer dial - though one could be ordered at extra cost - and the rim was smooth, not an ideal finish on a large lathe were oil-hands might need to reach out and grip the rim to apply a little extra cut.
Cross and top slides were of ample proportions and fitted with taper gib strips and crisply-engraved micrometer dials, that on the cross-slide being usefully large in diameter. While, as part of the standard equipment, a short, plain cross-slide with a swarf guard at the rear and just a single clamp-tpe toolpost were specified, the makers offered a very wide range of options, including 4 and 6-way, quick-change and rear toolposts on a raiser bock held ; a cross-slide of extended length that carried a top-slide with two tool holders; twin cross-slides each with their own top slide; twin cross-slides each with their own power-feed top-slide - though the twin cross-slide arrangement meant that neither taper turning nor hydraulic copying could be fitted and was not available on the E3. It was also possible (sensibly only on longer-bed versions) to order a second complete carriage assembly, complete with any of the previously-mentioned optional extras.
Supplied with each new E and V lathes was a chip tray, driving plate for between-centres work, fixed steady, travelling steady. Morse centres, bed-mounted carriage stop, cross-feed stop, spindle-speed table, spanners and operating instructions.
In addition to special machines built to a customer's specific orders, the factory listed a wide range of optional extras, these including a hardened bed, bed gap piece, spindle-nose bayonet fittings to DIN 55022 and standard American-type Camlock, an increased spindle-speed range, coolant equipment with electric pump, 4-way, 6-way and quick-set toolposts, taper turning, hydraulic copying attachment, power-feed to the top slide for short taper turning, extended cross slides, twin cross slides, twin cross slides with power to the top slides, a complete second carriage assembly, taper-turning attachment with micro setting by a very fine-pitch screw, a combined taper-turning and copying attachment on an extended cross slide, a power-boring tailstock (not on the E5 and V6) this presumably being connected to the carriage, faceplates with and without T-slots in cast-iron or steel, various 3 and 4-jaw chucks in cast-iron or steel and of standard or high accuracy, chucks with electric or pneumatic opening and closing, collet chucks, a micrometer dial with a vernier for length-travel indication on the carriage handwheel, a thread-dial indicators for inch and metric screwcutting, Ammeter, Kienzle speed and feed indicator, light unit and "special accuracy" lathes for toolroom work, but only in straight-bed versions and with up to a capacity of 59 inches between centres..
