Who uses the Apollo 1250 x 3000 and for what

The Bernardo Apollo 1250 x 3000 is one of the compact heavy-duty conventional lathes in the Apollo range, featuring 3,000 mm between centers and a 1,250 mm swing over bed, a medium configuration. The reinforced bed with a width of 755 mm and the ISO A2-15 spindle nose define its operating range: machining shafts, profiles, and cylindrical parts typical of medium-large industrial machine shops. The included 3-axis ES-12 V digital readout, the power transmission via a cardan shaft with hydraulic clutch, and the 36 speeds from 3.15 to 400 rpm with gear changes cover any material and geometry. The soft start of the spindle with mechanical coupling reduces stress on components when starting heavy workpieces. In Krollit customer workshops, the Apollo 1250 x 3000 is chosen by industrial machine shops, shipyards for repair and reconstruction of axles and shafts, manufacturers of turbine and generator components, and workshops specialized in precision turning of heavy parts.

Its place in the Bernardo range

The Bernardo Apollo family is the line of heavy-duty conventional lathes for industrial applications. It comprises 12 models organized by swing over bed (1000, 1250, 1600, 2000 mm) and distance between centers (1,500, 2,000, 3,000, 5,000, 8,000 mm). Family 1000-1250 (this model): ISO A2-15 attachment, 22 kW motor, 36 speeds from 3.15 to 400 rpm, 755 mm bed. Suitable for precision machining of medium-large parts. Above it: 1600 family with ISO A2-15 (970 mm bed) for more voluminous parts while maintaining a compatible structure; 1600 family with MT 7 (1,100 mm bed) for heavy industrial applications; 2000 family (top, MT 7, 22-30 kW motor, 2,300 mm gap) for heavy industrial production. Alongside the 1250 x 3000 in the same family: Apollo 1000 x 8000, Apollo 1250 x 1500, Apollo 1250 x 5000, Apollo 1250 x 8000. The choice between models in the family depends on the length of the parts: for long shafts, 8,000 mm distance between centers; for standard shafts, 3,000 mm; for short compact parts, 1,500 mm.

Frequently Asked Questions

What are the typical application sectors for the Apollo 1250 x 3000?

Marine (marine shafts, propellers, gearboxes), energy (turbine shafts, generators), heavy mechanical engineering (cylinders, pulleys, gears). The 3000 mm distance between centers and 1250 mm swing over bed define the operating range.

Examples of typical parts: long transmission shafts (components for marine engines), large cylindrical profiles (components for industrial machinery), industrial piping flanges. For specific parts, verify the maximum diameter, length, and weight of the part in relation to the machine's capabilities in advance.

What operational space does it require in the workshop?

Machine dimensions 6.1 × 1.88 × 1.92 m. For operational use (loading/unloading parts, handling, maintenance access), an overall area at least 1.5 times the machine's dimensions is needed, with adequate ceiling height.

Installation requires industrial flooring or a reinforced concrete foundation dimensioned for the machine's weight plus typical workpieces. For initial installation, it is recommended to consult a qualified installer for structural and site compliance assessment.

Is the ES-12 V 3-axis digital readout really necessary?

Yes, for precision production. The DRO displays the exact position of the axes in real-time, down to a hundredth of a millimeter, eliminating reading errors from graduated handwheels. On a heavy lathe of this size, positioning accuracy is crucial for the quality of machining operations.

Without a DRO, positioning accuracy depends on visual reading of the handwheels and compensating for screw backlash: errors of 0.1-0.2 mm are typical. With a DRO, positioning accuracy easily reaches 0.01 mm. On the Apollo, it is included as standard, unlike many entry-level industrial lathes from other brands where the DRO is an expensive optional accessory.

Is it better to get an Apollo 1250 or upgrade to the 1600 diameter?

It depends on the maximum diameter of typical workpieces. Up to Ø 1000 mm over the bed, the Apollo 1250 is correctly sized. For parts regularly above Ø 1062 mm, the 1600 family is necessary.

The 1600 family has a reinforced 970 mm bed (vs 755 mm), extended 820 mm X-travel (vs 630 mm), and higher weight. The cost is higher. For growing workshops or those with variable needs, it is strategically preferable to size correctly in advance. For established workshops with standardized production on the current maximum diameter, the additional investment is not justified.

What is the expected service life of an Apollo lathe?

For standard industrial use, the Apollo range is designed for an operational life of over 25-30 years with regular maintenance. Wear components (bearings, guides, lubrication system, clutches) are replaceable with original Bernardo spare parts.

The stabilized, hardened, and ground cast iron structure (a characteristic of Apollo lathes) does not wear significantly: the bed and headstock maintain precision for decades with proper maintenance. Mechanical components in contact are dimensioned for continuous industrial use and are replaced periodically. Original Bernardo spare parts are available from stock with shipping in 3-5 business days. For intensive use, a semi-annual preventive maintenance plan is recommended.
