Precision Lathe Profi 650 G / 400 V
The Bernardo Profi 650 G / 400 V geared head lathe is designed for precise and reliable machining of medium-sized workpieces. With a distance between centers of 650 mm and a swing over bed of 280 mm, it offers extensive application possibilities in workshops and laboratories. The 26 mm spindle bore with MT4 taper and the Norton gearbox with 12 adjustable speeds from 70 to 2000 rpm allow for various machining operations. The machine can produce metric and imperial threads with numerous combinations, thanks to the included gear set. The robust structure (202 kg) ensures stability, while the included accessories, such as an LED light and safety guards, guarantee comfort and reliability. A professional lathe that combines power and precision, suitable for workshop turning.

Frequently Asked Questions
What is the difference between Hobby and Profi in the Bernardo lathe range?
The Hobby series is designed for advanced hobbyists and small workshops: lower speeds, single-phase or three-phase motors of medium power, distances between centers up to 750 mm. The Profi series is for continuous professional use: more powerful motors, extended speeds, distances between centers up to 3000 mm, greater structural rigidity for machining hard materials. The suffix G indicates geared headstock; Vario indicates continuous speed adjustment.
What do the suffixes "G" and "Vario" in the name mean?
G (Getriebe) indicates geared speed change — more torque at low speeds, suitable for hard steels and large sections. Vario indicates continuous mechanical variator — speed can be adjusted without stopping the machine, suitable for quickly switching between roughing and finishing. Vario models have less torque at low speeds compared to G models, but more operational flexibility.
Is the 3-jaw self-centering chuck included as standard?
Yes — Bernardo Hobby and Profi lathes include a 3-jaw self-centering chuck, live center, and basic tools as standard. Optional accessories (4-jaw chuck, steady rest, follow rest, collets) are available separately from Krollit.
Are spare parts and assistance available?
Original spare parts available with 3–5 business days shipping. Customer support available in Italian.
How much space is needed in the workshop?
Consider at least the distance between centers clear in front and behind the lathe for workpiece handling, plus 80 cm on each side. For lathes over 300 kg, coordinate with Krollit for the necessary unloading equipment.
