Bernardo Profi 650 G / 230 V Lathe with ES-12 V DRO
The Bernardo Profi 650 G / 230 V lathe is a compact and precise solution for workshops, schools, and laboratories that seek reliability in a small footprint. With a distance between centers of 650 mm and a swing over bed of 280 mm, it easily handles small to medium-sized workpieces. The 12-step gear transmission (70–2000 rpm) offers quick and repeatable settings, while the 0.75 kW (S1) – 1.0 kW (S6) single-phase motor ensures continuous operation. The ES-12 V 2-axis digital readout (DRO) improves control and precision, reducing setup times. Complete with a Ø 125 mm self-centering chuck, 4-way tool post, LED light, guards, and gears for metric and imperial threading. A robust (202 kg), practical, and affordable lathe for quality machining.

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 machinable workpiece length. Profi 550 mm. The 26 mm spindle bore indicates the maximum diameter of bar stock that can pass through the spindle bore without machining. The G gear change provides more torque at low speeds compared to belt drive versions.
How does the G gear change work?
The Profi 650 uses a gear change (G) for speed variation: more torque at low speeds compared to belt variators, suitable for hard steels and large sections. Shifting occurs while stationary with the external lever — no need to disassemble belts.
The included ES-12 V DRO — how does it improve machining?
The included ES-12 V 2-axis DRO displays the real position of the longitudinal and cross slides with 0.01 mm resolution — eliminating the reading of graduated noniuses and reducing dimensional errors. Zero preset and turned diameter calculation are immediate operations without programming.
230 V power supply: is a transformer needed for the Profi 650?
230 V single-phase — connects directly to the standard Italian industrial socket (Schuko 16A). No transformer or three-phase panel is needed. Suitable for private workshops, workshops without a three-phase system, and vocational schools.
Are spare parts and assistance available?
Original spare parts available with 3–5 working days shipping. Customer support in Italian available.
