Bernardo Geared Lathe with Gap Bed Profi 650 G / 400 V with Digital Readout ES-12 V
The Bernardo Profi 650 G / 400 V lathe with 2-axis ES-12 V digital readout is designed for professional machining of steel, non-ferrous metals, and plastic. With a 26 mm spindle bore, a 160 mm wide induction-hardened bed, and a solid geared design, it guarantees precision and durability. The transmission with 12 mechanical speeds (70–2000 rpm) allows it to adapt to different materials and processes. The spindle, supported by precision tapered roller bearings, ensures high concentricity, while the ES-12 V digital readout facilitates accurate and repetitive machining. With automatic feeds, metric and inch thread cutting capabilities, and a complete set of accessories, it is the ideal choice for machine shops and laboratories.

Frequently Asked Questions
What is the difference between the Profi 650 and the Profi 550/700 models in the same series?
The number in the name indicates the distance between centers in mm — the maximum length of the workpiece that can be turned. Profi 550 mm. The 26 mm spindle bore indicates the maximum diameter of the bar that can pass through the spindle hole without turning. The geared (G) gearbox provides more torque at low speeds compared to belt-driven versions.
How does the geared (G) gearbox work?
The Profi 650 uses a geared (G) gearbox for speed variation: more torque at low speeds compared to belt-driven variable speed drives, suitable for hard steels and large sections. Shifting occurs from a standstill with the external lever — no belt disassembly is required.
The included DRO ES-12 V — how does it improve machining?
The included 2-axis ES-12 V DRO shows the actual position of the longitudinal and cross slide with a resolution of 0.01 mm — eliminating reading graduated verniers and reducing dimensional errors. Zero preset and calculation of the turned diameter are immediately operational without programming.
400 V power supply: is a transformer needed for the Profi 650?
400 V three-phase — requires a three-phase electrical system (not available in standard private homes). Before purchasing, verify the presence of a three-phase system and the power of the electrical panel.
Are spare parts and assistance available?
Original spare parts available with 3–5 working days shipping. Customer support in Italian available.
