Frequently Asked Questions
What is the difference between the Profi 900 and the Profi 550/700 models in 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 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 Vario electronic variator?
The electronic variator (Vario) allows continuous speed adjustment without stopping the machine — you can switch from roughing to finishing by turning the knob in 2 seconds. The torque remains high even at low speeds, unlike mechanical belt variators. On the Profi 900, it covers the full range indicated in the table without steps.
900 V power supply: is a transformer needed for the Profi 900?
400 V three-phase — requires a three-phase electrical system (not available in standard private homes). Before purchasing, check for a three-phase system and the power of the electrical panel.
Are spare parts and assistance available?
Original spare parts available with 3–5 working day shipping. Customer support available in Italian.
