Bernardo Profi 700 BQV Vario Lathe / 230 V
The Bernardo Profi 700 BQV Vario / 230 V lathe is a compact and robust machine, suitable for workshops, laboratories, and demanding hobbyists. With a 38 mm spindle bore and an induction-hardened bed, it ensures stability and precision when machining steel, non-ferrous metals, and plastics. The continuous electronic speed adjustment (50–1800 rpm) allows for adaptability to different materials, while thermal protection with a warning light safeguards the motor from overloads. Equipped with a leadscrew and feed rod, it enables automatic feeds and metric and imperial threading. The spindle, supported by tapered roller bearings, guarantees a concentricity of ≤0.015 mm. Supplied with a 4-way tool post and professional accessories, it represents a versatile and safe lathe.

Frequently Asked Questions
What is the difference between the Profi 700 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 38 mm spindle bore indicates the maximum diameter of the bar that can pass through the spindle bore without turning. The Vario variator adds continuous speed adjustment compared to the standard models in the same range.
What changes with the electronic Vario variator?
The electronic variator (Vario) allows for continuous speed adjustment without stopping the machine — you can switch from roughing to finishing by turning a knob in 2 seconds. Torque remains high even at low speeds, unlike mechanical belt variators. On the Profi 700, it covers the full range indicated in the table without steps.
230 V power supply: is a transformer needed for the Profi 700?
230 V single-phase — it connects directly to a standard Italian industrial socket (Schuko 16A). No transformer or three-phase panel needed. Suitable for private workshops, workshops without a three-phase system, and vocational schools.
Spare parts and assistance available?
Original spare parts available with 3–5 business day shipping. Customer support available in Italian.
