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 variator ensures continuous, stepless speed adjustment. The 750 series typically has a larger spindle bore than the 550. Choose the 750 when workpiece lengths frequently exceed 500 mm.

Why choose the 400 V three-phase version instead of the 230 V?

The 400 V three-phase version has higher torque at low speeds and less overheating during intensive continuous use — the correct choice for workshops with a three-phase system and continuous professional production. The 230 V version is suitable for advanced hobbyists and small workshops without a three-phase system.

Are spare parts and accessories available?

Available accessories: 4-jaw chuck, steady rests, quick-change tool post, additional DRO. Original spare parts available with 3–5 working day 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.
