Our best estimate for the Citizen Miyano BNA-42GTY is $250,000 - $380,000. This is an estimate for a mill-turn / multi-tasking machines in this class, not a quote from Citizen Machinery; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/citizen-miyano-bna42gty#price; the request is passed to Citizen Machinery or an authorised dealer.
Bar work is listed to 42 mm dia. on the first spindle and 34 mm dia. on the second. Maximum machining length is 100 mm, so the machine is aimed at short parts.
It is an 8-station turret with a half-indexing mechanism and up to 8 revolving tools. Turning tools are 20 mm Sq. and drill shanks 25 mm dia. Check how the other axis groups are tooled on the machine you are considering.
Z1 30 m/min, X1 24 m/min and Y1 30 m/min; Z2 20 m/min, X2 20 m/min and Y2 12 m/min; Z3 20 m/min and X3 12 m/min. The first group is the fastest, so the operations with the most moves belong there.
The Miyano BNA-42MSY also uses an 8-station half-indexing turret, listed as 16 effective positions, runs revolving tools to 6,000 RPM and weighs 3,000kg. The BNA-42GTY weighs 3,750 kg and lists rapid rates for a third axis group, X3 and Z3.
