Our best estimate for the Citizen Miyano BNE-51S6 is $210,000 - $290,000. This is an estimate for a cnc lathes / turning centers 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-bne-51s6#price; the request is passed to Citizen Machinery or an authorised dealer.
The table lists 51 mm dia. for SP1 and 42 mm dia. for SP2, with 6" and 5" chucks. SP2 grips the part after cut-off for back working, so the end it holds must be 42 mm dia. or less. Design the part with a reduced back end, or choose a model with equal spindles.
The Miyano BNE-42S6 takes 42 mm dia. on both spindles, uses 5" chucks on both and runs SP1 to 6,000 rpm at 7,600 kg. The BNE-51S6 raises SP1 to 51 mm dia. with a 6" chuck, lowers SP1 speed to 5,000 rpm and weighs 7,800 kg.
No Y-axis stroke is listed for it. The Miyano BNE-51SY6 is the version with ±40 mm of Y on HD1; spindles, turrets, motors and the 7,800 kg weight are otherwise the same.
HD1 travels 175 mm in X1 and 380 mm in Z1. HD2 travels 145 mm in X2 and 175 mm in Z2. The back spindle has 450 mm of travel. Both turrets take 20 mm Sq. turning tools and 25 mm dia. tool holes.
