Frequently Asked Questions
The Profi 550 WQ — what does WQ mean and what distinguishes it from the LZ and PRO models?
WQ indicates a Quick Change toolpost as standard — the main difference compared to the LZ and PRO models with the same distance between centers. The quick change allows each tool to be replaced in 5–10 seconds while maintaining a repeatable cutting edge height. For workshops with frequent tool changes, it is the most productive model in the 550 series.
400 V three-phase — does it require a special electrical system?
Yes — it requires a 400V three-phase system (not available in standard private homes). Before purchasing, check for three-phase power and the capacity of the electrical panel. For workshops without three-phase, the Profi 550 WQV / 230V (single-phase version with variator) is available.
Are spare parts and accessories available?
Available accessories: 4-jaw chuck, steady rests, additional DRO. Original spare parts available with 3–5 business days shipping. Customer support in Italian available.
How much does it weigh and what space does it require?
Check weight and dimensions in the technical table. For machines over 300 kg, coordinate with Krollit for the necessary unloading equipment. Customer support in Italian available.
