Bernardo Master 400 x 1500 parallel lathe – 3-axis digital readout included

The Bernardo Master 400 x 1500 is a universal parallel lathe for professional use, with a centre distance of 1,500 mm, a swing over bed of 400 mm, a 52 mm spindle bore and the ES-12 V 3-axis digital readout included as standard. Bernardo is an Austrian brand based in Linz. Distributed in Italy by Krollit, official Bernardo distributor since 2007. Centre distance: 1,500 mm Centre height: 200 mm Swing over bed: 400 mm Swing in gap (removable bridge): 560 mm Spindle bore: 52 mm Spindle mount: DIN 55029, D1-5 Speed range: 12 speeds, 45–2,000 rpm Threads: 36 metric (0.8–14 mm) and 30 imperial (2–28 TPI) Motor power: 2.0 kW / 2.4 kW ES-12 V 3-axis digital readout with LCD display included Weight: approx. 930 kg Who uses the Master 400 x 1500 and what for The Master 400 x 1500 is used in technical schools and vocational training centres, where the straightforward speed and feed controls and the CE-compliant foot brake pedal make it suitable for teaching. Repair and maintenance workshops use it to machine shafts up to 1,500 mm between centres, taking advantage of the two steady rests included for slender workpieces. Toolmaking shops choose it for the 52 mm spindle bore, which allows large-diameter bar stock to be machined, and for the removable gap bridge that increases the swing to 560 mm on short, large-diameter parts such as flanges and pulleys. Who the Master 400 x 1500 is for Profile Compatibility Reason Technical schools and training Suitable Clear controls, CE foot brake, safety clutch as standard and a 3-axis readout for learning position reading Repair and maintenance workshops Suitable 1,500 mm between centres, fixed and travelling steady rests included, 3-jaw and 4-jaw chucks supplied Toolmaking and tool building Suitable 52 mm spindle bore, 36 metric and 30 imperial threads selectable, cross feeds down to 0.01 mm/rev Continuous series production Not recommended Conventional machine with manual gear change, no cycle automation Not recommended for: high-volume series production, where a CNC lathe reduces cycle times, and hobby workshops with limited space, considering the 930 kg weight and the 2,360 mm overall width. Construction and safety The grey cast iron bed is induction hardened and ground, with a heavy-duty cast iron base. The gears, including those in the feed gearbox, are hardened and ground. The spindle runs on high-quality angular contact ball bearings. The machine comes as standard with a leadscrew and feed rod, a safety clutch, a CE-compliant electromechanical foot brake that reduces idle time between operations, and a motor with a CE-compliant magnetic brake. The tailstock can be offset by ± 5 mm for taper turning, and the chip tray pulls out from the front, reducing the space required for installation.

The swing is 400 mm over the bed, 560 mm in the gap with the bridge removed and 240 mm over the cross slide. The removable bridge in front of the headstock allows short, large-diameter parts such as flanges, pulleys and discs up to 560 mm to be machined, while retaining the rigidity of the induction-hardened cast iron bed for standard work between centres up to 1,500 mm in length. What is the ES-12 V digital readout included as standard for? The ES-12 V 3-axis readout with LCD display shows the axis positions in real time, reducing reading errors and measuring time. Compared with reading the dials alone, the digital readout speeds up repeated positioning and machining to dimension, a concrete advantage in repair workshops and in teaching environments. On the Master 400 x 1500 it is part of the standard equipment, at no extra cost. What is the advantage of the 52 mm spindle bore? The 52 mm bar capacity allows large-diameter bars and shafts to be machined by passing them through the spindle. For a lathe in this class it is a generous value: it makes it possible to face and thread long bars without excessive overhang, reducing vibration and improving surface finish. The DIN 55029 D1-5 spindle nose mount ensures quick mounting of the self-centring chucks supplied. Which threads can be cut? The machine cuts 36 metric threads from 0.8 to 14 mm pitch and 30 imperial threads from 2 to 28 threads per inch. The dedicated leadscrew, separate from the feed rod, preserves pitch accuracy over time. The thread dial indicator included as standard makes it easier to re-engage the half nuts on subsequent passes, while the change gears supplied cover the entire stated range. Is taper turning possible? Yes, the tailstock can be offset transversely by ± 5 mm, a method suited to long tapers with a small taper angle. For short tapers, the top slide is rotated instead. The tailstock offset acts on workpieces mounted between centres and must be reset to zero after the operation to restore alignment, which can be checked with a dial indicator on a test bar. How does the electromechanical foot brake work? The CE-compliant pedal with brake function stops the spindle rotation quickly, reducing idle time between operations. The foot brake is complemented by the motor with a magnetic brake, also CE-compliant, and by the standard safety clutch that protects the drive train in the event of overload. This configuration also makes the machine suitable for training environments, where operator safety is a decisive requirement. How is a 930 kg machine delivered? Delivery is to ground floor with tail lift included, within 5-9 working days (7 days for southern Italian regions). Positioning in the workshop requires a pallet truck or forklift suited to the 930 kg weight and the 2,360 x 800 x 1,600 mm footprint.
