Frequently Asked Questions

The Profi 750 Vario — what does it add compared to the Profi 550 and Profi 700?

The distance between centers (750 mm) is greater than the Profi 550 (550 mm) and Profi 700 (700 mm) — allowing longer shafts and bars to be machined without external support. The electronic Vario speed control ensures continuous stepless speed adjustment. The 750 series typically has a larger spindle bore than the 550. Choose the 750 when workpiece length frequently exceeds 500 mm.

Does the 230 V single-phase version cover all typical applications?

For advanced hobbyists, schools, and workshops with standard single-phase electrical systems, the 230 V version is sufficient. The Vario variator partially compensates for the lower torque at low speeds compared to three-phase. For intensive continuous production on hard steels, consider the 400 V three-phase version.

Are spare parts and accessories available?

Accessories available: 4-jaw chuck, steady rests, quick-change tool post, additional DRO. Original spare parts available with 3–5 working days shipping. Customer support available in Italian.

How much space does the Profi 750 require in the workshop?

Allow at least 750 mm clear space in front of and behind the lathe for workpiece handling, plus 80 cm on each side for safe operation. The weight of over 300 kg requires a solid industrial floor — coordinate with Krollit for necessary unloading equipment.
