Our best estimate for the Chiron 831 MT is $650,000 - $950,000. This is an estimate for a mill-turn / multi-tasking machines in this class, not a quote from Chiron; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/chiron-831-mt#price; the request is passed to Chiron or an authorised dealer.
The listed maximum workpiece diameter is 400 mm (15.7 in). Workpiece length, weight and bar diameter are not given, so the diameter is the only limit that can be read from this page. Check length and weight before planning shaft-type or heavy chuck parts.
Yes, going by the listed figures. The spindle configuration is given as separate turning and milling spindles, and the machine is described as five-axis simultaneous mill-turn. Speed, power and tool interface are not given for either spindle.
The listed figures call it capable of both bar stock and chuck work, and give the machining type as complete machining from bar or chuck. The bar diameter is missing, so compare your stock sizes with a data sheet before counting on bar feed.
