Magdeburg D30 Precision
Built in Heidelberg (West Germany) and of outstandingly high quality, the Magdeburh precision production lathe was intended to impart a fine surface finish at high speed to small batches of components. The centre height was 140 mm and a choice of 500, 700 and 900 mm was available between centres. Weighing 950 kg and with the bed and headstock cast as one - an unusual method of construction for so relatively large a lathe - the machine was immensely rigid and able to take very heavy cuts. No screwcutting was fitted and the spindle, which ran in pressure-lubricated parallel-bore plain bronze bearings, was driven by a set of three twin V-belts arranged as a pulley overhung from its left-hand bearing. To suit the needs of buyers, several different drive systems were available ranging from a choice of 1, 2 and 3-speed motors, that gave spindle speeds from 600 to 3000 r.p.m., to a hydraulic-drive unit that provided virtually full torque across a speed range of either 60 to 425 r.p.m. or 425 r.p.m to 1800 r.p.m Power cross feed was fitted as standard - a button selector on the apron switched between sliding and surfacing - as was a taper-turning attachment. A quick-indexing 4-way toolpost was part of the standard equipment, as was a particularly robust rear toolpost..
