Who uses the Profi 400 V and for what
The Bernardo Profi 400 V is a compact bench lathe from the Profi range (professional entry-level), sized for advanced hobbyists, model makers, and small workshops. Profi 400 V features: 400 mm distance between centers, 65 kg weight, 930 × 400 × 380 mm dimensions. A variant of the Profi 400 G with lower center height (100 mm vs 105 for the 400 G) and spindle bore 20 mm (vs 21 for the 400 G): subtle differences between the two models that meet specific needs for compatibility with existing accessories. DK11 Ø 100 mm MT3 taper chuck, 65 kg weight (5 kg more than the 400 G due to more complete standard equipment). Same continuous electronic variable speed and same 0.60 kW motor as the Profi 400 G. 3-step automatic longitudinal feeds (0.083-0.159 mm/rev in the 300 V, 0.089-0.198 in the 400 G/400 V) for finish control. 14-15 step metric threads (0.3-3 mm) and 10-12 step inch threads (10-44 TPI): standard coverage for common threaded part production. Digital speed indicator for precise control of the set rpm. In Krollit customer workshops, compact Profi lathes are chosen by advanced hobbyists who want professional features (threading, feeds, display) in compact bench machines without the need for a dedicated stand.
Its place in the Bernardo range
The Bernardo Profi metal lathe range is organized by progressive sizes and features: Profi 300 V, 400 G, 400 V (compact 60-65 kg, 0.50-0.60 kW motor, electronic variable speed) for advanced hobbyists and small workshops; Profi 450 S and 450 S Vario (medium 112 kg, 0.90 kW motor) for craft workshops with daily use; Profi 550 WQ and 550 WQV (heavy 120 kg, 0.75 kW motor but with separate longitudinal+transversal feeds and complete threading) for professional production of complex threaded parts. Below the Profi range is the Hobby range (entry-level 14-130 kg); above is the Goliath range (heavy industrial 1,500-3,500 kg).
The Profi 400 V is the professional entry-level of the Profi range: professional features (complete threading, automatic feeds, digital speed display) in a compact bench machine. For continuous professional use with larger parts, the Profi 450 S/450 S Vario (112 kg) or 550 WQ/WQV (120 kg) is correctly sized. For heavy industrial production, the Goliath range is correctly sized. The 3 compact models (300 V, 400 G, 400 V) differ in: 300 V is more compact and slightly less powerful, 400 G has a Ø 21 mm spindle bore and 105 mm center height, 400 V has a Ø 20 mm bore and 100 mm center height.

Who is the Profi 400 V for
| Profile | Compatibility | Reason |
|---|---|---|
| Advanced hobbyist / professional model maker | Recommended | Compact 65 kg lathe with professional features: complete metric+inch threading, automatic feeds, digital speed display. 400 mm distance between centers and Ø 200 mm over bed for small-medium parts. |
| Small craft workshop | Recommended | DK11 Ø 100 mm chuck with through-hole for using standard accessories (collets, reductions, 4-jaw chucks for special accessories). Continuous electronic variable speed for tuning to different materials. |
| Workshop with regular production and large parts | Adequate | For intensive use with parts over Ø 200-210 mm on the bed, the Profi 450 S/Vario (Ø 230 mm) or 550 WQ/WQV (Ø 250 mm) with a more powerful motor is correctly sized. |
Not suitable for: daily professional use with large parts (over Ø 210 mm on the bed; the Profi 450 S/Vario or 550 WQ/WQV is correctly sized); workshops without a 230V industrial line with good capacity (0.50-0.60 kW motor requires a suitably sized domestic meter); 400V three-phase power supply (for workshops with a three-phase line, the 400V version of the Hobby 500 or Goliath range is correctly sized); programmed CNC (Profi are manual lathes, not CNC).

Frequently asked questions
What is the difference between the Profi 400 V and the Hobby models in the range?
The compact Profi models are a step above the Hobby models: professional features (complete metric+inch threading, DK11 Ø 100 mm chuck, digital speed display, 0.50-0.60 kW motor) in a compact bench machine. Hobby models are entry-level with more simplified features (optional threading on basic models, smaller diameter chucks, 0.15-0.55 kW motors).
Practical difference: for occasional hobby use, a Hobby 250/350 is sufficient; for more intensive use with professional threading requirements, the compact Profi is correctly sized. The medium Profi range (450 S/Vario) and heavy (550 WQ/WQV) are sized for daily professional or continuous advanced hobby use.
Is the 230V single-phase power supply truly sufficient for professional use?
For the Profi 400 V, yes. The 0.6 kW (S1) - 0.8 kW (S6) motor is sized for continuous use with 230V single-phase. The machine is sized for professional craft workshop use, not for heavy industrial production.
Recommended check before installation: electrical line with adequate cross-section (4 mm² cable for 0.90+ kW motor, 2.5 mm² for 0.50-0.80 kW motors), dedicated 16-20A circuit breaker, industrial CEE 16A 230V socket. For workshops with other simultaneous loads (compressors, extractors), check the available power on the meter (minimum 6 kW for simultaneous use). For heavy industrial use, the Goliath range with a 9 kW three-phase 400V motor is sized.
What parts can I work with the Profi 400 V?
Typical parts: cylindrical turning of shafts and cylinders up to Ø 200 mm and 400 mm length between centers, facing, grooving, chamfering and filleting, metric threads (14) 0.3-3 mm and inch threads (10) 10-44 TPI. Typical materials: mild steels (Fe360, S235), alloy steels (C45, 39NiCrMo3), stainless steels (AISI 304, 316), aluminum and light alloys, brass, bronze, technical plastics.
Limitations: maximum Ø on the bed 200 mm, spindle bore Ø 20 mm (maximum limit for through bars). For larger parts, the higher models in the Profi range or the Goliath range are correctly sized. For standard occasional hobby use, all Profi models are suitable; for regular production with specific parts, check the capacity of the chosen model.
Can I install the Profi 400 V on any workbench?
Yes, on robust workbenches with a load capacity greater than the machine's weight (65 kg) plus the workpieces. The bench must be stable and level: instability causes vibrations that compromise work precision.
For craft workshops, a professional workbench (e.g., WB 2100 Profi from the Bernardo range) with a solid beech wood top, or a dedicated steel sheet stand, is recommended. The machine must be fastened to the bench with through bolts in the provided base holes to prevent sliding during operation.
Is the machine already complete or do I need additional accessories?
The machine comes with standard equipment sufficient for immediate use: DK11 Ø 100 mm self-centering chuck, four-way tool post, fixed tailstock, steel spare gears, spindle guard, chip tray, spare wheels.
Optional accessories typically purchased separately: self-centering chucks of different diameters, steady rests for long parts, 4-jaw chuck for non-cylindrical parts, additional turning tool sets (HSS, carbide), MT3/MT4 collets. For most standard machining operations, the basic equipment is sufficient; for specific productions, consider dedicated accessories. All original Bernardo accessories are available from Krollit with 3-5 business day shipping.
