Our best estimate for the Chiron 831 MT Twin is $850,000 - $1,250,000. 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-twin#price; the request is passed to Chiron or an authorised dealer.
It is listed as a twin-spindle machine with separate turning and milling spindles per station, and its machining type is given as dual part simultaneous. Two workpieces are cut in the same cycle, where a single-station machine finishes one.
That cannot be answered from the table. It gives a maximum workpiece diameter of 400 mm (15.7 in) but not the spacing between the stations. Until the spacing is confirmed, do not assume the full diameter is available on both sides together.
