Frequently Asked Questions

What is the difference between the Profi 550 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 26 mm bar passage indicates the maximum diameter of the bar that can pass through the spindle bore without turning.

How do you change the speed?

The Profi 550 uses standard belt speed change with stepped pulleys. Changing the speed requires stopping the machine and manually moving the belt.

230 V power supply: is a transformer needed for the Profi 550?

230 V single-phase — it connects directly to a standard Italian industrial socket (Schuko 16A). No transformer or three-phase panel is needed. Suitable for private workshops, workshops without a three-phase system, and vocational schools.
