Features of the Profi 400 G: 400 mm distance between centers, 60 kg weight, dimensions 930 × 400 × 380 mm. Intermediate model in the compact Profi range: greater capacity than the Profi 300 V (Ø 210 vs 180 mm swing over bed) for medium-sized workpieces. DK11 Ø 100 mm 3-jaw chuck with Ø 21 mm bore, MK3 taper (1 mm larger bore than Profi 300 V and Profi 400 V). Same variable speed (50-1250\/100-2500 rpm) and same threading configuration as the 300 V and 400 V, but with a slightly more powerful motor (0.60 kW S1 vs 0.50 for the 300 V). 3-step automatic feeds (0.083-0.159 mm\/rev in 300 V, 0.089-0.198 in 400 G\/400 V) for finish control. Metric threads 14-15 steps (0.3-3 mm) and inch threads 10-12 steps (10-44 TPI): standard coverage for common threaded parts 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.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\n\u003cp\u003eThe Bernardo Profi metal lathe range is organized by progressive size 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 artisanal workshops with daily use; Profi 550 WQ and 550 WQV (heavy 120 kg, 0.75 kW motor but with separate longitudinal+cross feeds and comprehensive threading) for professional production of complex threaded parts. Below the Profi range is the Hobby range (entry-level 14-130 kg); above it is the Goliath range (heavy industrial 1,500-3,500 kg).\u003c\/p\u003e\n\u003cp\u003eThe Profi 400 G is the professional entry-level model of the Profi range: professional features (comprehensive threading, automatic feeds, digital speed display) in a compact bench machine. For continuous professional use with larger workpieces, the Profi 450 S\/450 S Vario (112 kg) or 550 WQ\/WQV (120 kg) is appropriately sized. For heavy industrial production, the Goliath range is appropriately sized. The 3 compact models (300 V, 400 G, 400 V) differ in: 300 V being more compact and slightly less powerful, 400 G with Ø 21 mm spindle bore and 105 mm center height, 400 V with Ø 20 mm bore and 100 mm center height.\u003c\/p\u003e\n\u003ch3\u003eKrollit logistics and support\u003c\/h3\u003e\n\u003cp\u003eBernardo shipping in 5-9 business days (7 days to the South).

The Hobby models are entry-level with simpler features (optional threading on basic models, smaller diameter chucks, 0.15-0.55 kW motors).\u003c\/p\u003e\n\u003cp\u003ePractical difference: for occasional hobby use, a Hobby 250\/350 is sufficient; for more intensive use with professional threading requirements, the compact Profi is appropriately sized. The medium Profi range (450 S\/Vario) and heavy (550 WQ\/WQV) are sized for daily professional or continuous advanced hobby use.\u003c\/p\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs the 230V single-phase power supply truly sufficient for professional use?\u003c\/summary\u003e\n\u003cp\u003eFor the Profi 400 G, yes. The 0.6 kW (S1) - 0.8 kW (S6) motor is sized for continuous use at 230V single-phase. The machine is sized for professional artisanal workshop use, not for heavy industrial production.\u003c\/p\u003e\n\u003cp\u003eRecommended 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, CEE 16A 230V industrial 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 appropriately sized.\u003c\/p\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eWhat workpieces can I process with the Profi 400 G?\u003c\/summary\u003e\n\u003cp\u003eTypical workpieces: cylindrical turning of shafts and cylinders up to Ø 210 mm and 400 mm length between centers, facing, grooving, chamfering and radiusing, metric threads (15) 0.3-3 mm and inch threads (12) 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.\u003c\/p\u003e\n\u003cp\u003eLimits: maximum Ø over bed 210 mm, spindle bore Ø 21 mm (maximum limit for through bars). For larger workpieces, the upper models of the Profi range or the Goliath range are appropriately sized. For standard occasional hobby use, all Profi models are adequate; for regular production with specific workpieces, check the capacity of the chosen model.\u003c\/p\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eCan I install the Profi 400 G on any workbench?\u003c\/summary\u003e\n\u003cp\u003eYes, on sturdy workbenches with a load capacity greater than the weight of the machine (60 kg) plus the workpieces being processed. The workbench must be stable and level: instability causes vibrations that compromise the precision of the work.\u003c\/p\u003e\n\u003cp\u003eFor artisanal workshops, a professional workbench is recommended (e.g., WB 2100 Profi from the Bernardo range) with a solid beech wood top, or a dedicated steel sheet stand. The machine must be bolted to the workbench using through bolts in the provided base holes to prevent sliding during machining.\u003c\/p\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs the machine already complete or do I need additional accessories?\u003c\/summary\u003e\n\u003cp\u003eThe machine comes with standard equipment sufficient for immediate use: DK 11 Ø 100 mm 3-jaw self-centering chuck, four-way tool post, fixed center, steel spare gears, spindle guard, chip tray, spare wheels.\u003c\/p\u003e\n\u003cp\u003eOptional accessories typically purchased separately: self-centering chucks of different diameters, steady rests for long workpieces, 4-jaw chuck for non-cylindrical workpieces, additional turning tool sets (HSS, carbide), collets for MK3\/MT4 spindle. For most standard machining operations, the basic equipment is sufficient; for specific productions, evaluate dedicated accessories.
