Who uses the Goliath 660 × 1,500 and for what
The Bernardo Goliath 660 × 1,500 is a heavy-duty industrial lathe for mechanical construction and large part production. Structural feature: monobloc cast iron bed that eliminates torsion and vibrations even during heavy-duty operations. The swing over bed of Ø 660 mm (Ø 870 mm with gap bed removed) allows the machining of parts typical of heavy industry: large diameter drive shafts, hubs, flanges, hydraulic cylinders, rolling mill rolls, industrial machinery parts. The Ø 105 mm spindle bore with D1-8 mount (DIN 55029 standard) allows machining of bar stock with direct pass-through up to that diameter: a key feature for bar stock production. The 16-speed transmission from 36 to 1,600 rpm covers all needs: low rotation (36 rpm) for rough threading on large parts, standard rotation (100-400 rpm) for turning hard steels, high rotation (1,600 rpm) for finishing soft materials. The 65 longitudinal and 65 cross feeds allow optimal adaptation to any material and finish. The 3-axis digital display ES-12 V (included as standard) replaces manual vernier readings with a resolution of 0.005 mm. The 9 kW (12 HP) motor with CE magnetic brake allows rapid stopping for operator safety. In Krollit customer workshops, the Goliath 660 × 1,500 is chosen by industrial mechanical construction workshops, maintenance of components for heavy industries (cement factories, paper mills, steelworks), production of large single pieces, and repair of industrial shafts and cylinders.
Its place in the Bernardo range
The Bernardo Goliath industrial lathe range is sized for mechanical construction and heavy production: Goliath 510 × 1,000 (compact model), Goliath 660 × 1,500 (standard model), Goliath 800 × 2,500 (large model), Goliath 1,000 × 3,000 (extra-large model). All models share industrial characteristics: monobloc cast iron bed, large thru-hole spindle (Ø 80-160 mm), multi-speed transmission with mechanical gearbox, fixed + traveling steady rests included, CE magnetic brake, 3-axis DRO ES-12 V. The Goliath 660 × 1,500 is the most requested model in the range: a central size that balances capacity (Ø 660 mm over bed, 1,500 mm distance between centers) and footprint (3,000 × 1,280 × 1,650 mm). For smaller parts (Ø below 510 mm), the Goliath 510 × 1,000 is significantly more economical; for very large parts (over Ø 800 mm), the 800 × 2,500 or 1,000 × 3,000 models are correctly sized. For professional but not heavy industrial workshops, the Bernardo Profi range (200-500 kg) is significantly more economical and suitable for standard daily use.

Frequently Asked Questions
Does the machine require a special floor?
Yes. The Goliath 660 × 1,500, with a weight of 3,630 kg, requires an industrial floor with a minimum load capacity of 2,000 kg/m². For workshops with standard flooring (1,000-1,500 kg/m²), it is recommended to reinforce with a load distribution plate (10-15 mm thick steel plate larger than the machine's base).
For environments with unsuitable flooring (e.g., workshops in older or non-originally industrial buildings), it is essential to verify the structural load capacity of the slab: a 3,630 kg machine in a concentrated area can cause floor damage or structural failure. For doubtful cases, a structural engineer's inspection is recommended. For environments with limited access (ramps, elevators), machine transport requires specific planning with specialized carriers.
Is the 3-axis DRO ES-12 V included or optional?
Included as standard equipment with the Goliath 660 × 1,500. The 3-axis digital display ES-12 V measures the absolute and relative positions of the X (cross slide), Y (top slide), and Z (longitudinal slide) axes with a resolution of 0.005 mm. It replaces manual vernier readings on graduated scales, reducing reading errors and setup times.
Standard DRO functions: absolute vs. relative position (zeroing for workpiece reference), inches vs. mm, integrated calculator, storage of 100-200 useful points, automatic calculation of complex threads and PCD (pitch circle diameter). For productions with complex machining cycles, the DRO significantly reduces manual positioning times.
What typical parts are machined with this lathe?
Large industrial parts: large diameter drive shafts (up to Ø 660 mm and 1,500 mm length), hubs and flanges for industrial motors, hydraulic press or machinery cylinders, rolling mill rolls and calenders, parts for cement factories, paper mills, steelworks, and construction of machine tool components.
For smaller parts (Ø below 200 mm), the Goliath is excessively oversized: long setup times and disproportionate 9 kW motor. For very large parts (over Ø 800 mm or length over 2,000 mm), the Goliath 800 × 2,500 or 1,000 × 3,000 models are recommended. The Ø 660 mm diameter with the gap bed removed allows parts up to Ø 870 mm: typically large diameter flanges and discs.
Do the 16 speeds cover all materials?
Yes. The 36-1,600 rpm range covers all typical industrial turning needs: low rotation (36-100 rpm) for rough threading and turning large parts on hard materials, standard rotation (200-800 rpm) for turning mild and medium-hard steels, high rotation (1,000-1,600 rpm) for finishing soft materials (aluminum, brass) and for turning small parts with carbide tools.
Optimal speed depends on: material (mild steels 80-150 m/min, hard steels 50-80 m/min, stainless steel 30-60 m/min, aluminum 200-400 m/min), workpiece diameter (linear cutting speed must be constant), type of operation (roughing lower speeds, finishing higher speeds). For regular production, it is recommended to record optimal speeds on a work card for reference.
Are the fixed and traveling steady rests included?
Yes. Both are included as standard equipment: fixed steady rest with passage up to Ø 250 mm and traveling steady rest with passage up to Ø 110 mm. The fixed steady rest supports long workpieces during turning (prevents workpiece deflection under load), while the traveling steady rest moves with the carriage for continuous support.
For very thin parts (Ø below 30-40 mm) or very long parts (length/diameter ratio over 10:1), steady rests are essential to prevent deflection and vibrations that compromise finish quality. Additional steady rests of different diameters are available in the Bernardo accessories catalog for specific cases. For long shaft production, simultaneous use of a fixed steady rest (at the middle of the workpiece) and a traveling steady rest (near the tool) is recommended.
