Frequently asked questions
What is the difference between the Profi 750 and the Profi 550/700 models of the same series?
The number in the name indicates the distance between centers in mm — the maximum turnable workpiece length. Profi 550 mm. The 26 mm spindle bore indicates the maximum diameter of the bar passing through the spindle bore without turning. The G gear change delivers more torque at low speeds compared to belt versions.
How does the G gear change work?
The Profi 750 uses gear change (G) for speed variation: more torque at low speeds compared to belt variators, suitable for hard steels and large sections. Switching is done from a standstill with the external lever — no belt removal required.
230 V power supply: is a transformer needed for the Profi 750?
230 V single-phase — connects directly to the 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 assistance available in Italian.
