Bernardo Geared Lathe with Gap Bed Profi 550 LZ / 230 V
The Bernardo Profi 550 LZ / 230 V lathe is a compact and reliable model, designed for precision machining in workshops and training laboratories. Equipped with a lead screw and feed rod, it offers stability and versatility even for complex jobs. With a 26 mm spindle bore, induction-hardened bed, and ground guides, it guarantees long life and constant precision. The continuously variable speed from 50 to 2000 rpm allows it to adapt to different materials, while the spindle, mounted on high-quality tapered bearings, ensures concentricity of ≤0.015 mm. Suitable for turning, metric and imperial threading, it comes complete with a self-centering chuck, tool post, and professional accessories.

Frequently Asked Questions
What is the difference between the Profi 550 and the Profi 550/700 models of the same series?
The number in the name indicates the distance between centers in mm — the maximum turning length of the workpiece. Profi 550 mm. The 26 mm spindle bore indicates the maximum diameter of the bar that can pass through the spindle bore without turning. The G geared change provides more torque at low speeds compared to belt versions.
How does the G geared change work?
The Profi 550 uses geared change (G) for speed variation: more torque at low speeds compared to belt variators, suitable for hard steels and large sections. Shifting occurs from standstill with the external lever — no belt disassembly required.
230 V power supply: is a transformer needed for the Profi 550?
230 V single-phase — connects directly to a standard Italian industrial socket (Schuko 16A). No transformer or three-phase panel required. 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 available in Italian.
