Our best estimate for the Citizen Miyano BNA-42DHY3 is $210,000 - $320,000. 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-bna-42dhy3#price; the request is passed to Citizen Machinery or an authorised dealer.
The BNA-42DHY3 has two turrets, an eight-station for SP1 and a six-station for SP2, so both spindles can be cut at once. The Miyano BNA-42MSY2 has a single 8-station turret with a half-indexing mechanism but a stronger 11/7.5 kW SP1 motor. Both take 42 mm dia. bar on SP1 and 34 mm dia. on SP2, with 100 mm maximum machining length.
SP1 machines bar up to 42 mm dia. and SP2 up to 34 mm dia. Power chucks are 5" on SP1 and 4" on SP2. A part whose back end is larger than 34 mm dia. cannot be gripped on SP2 for back working.
X1 is 140 mm and Z1 235 mm on the SP1 turret slide, which also has a Y axis of 70 mm(±35). The second slide has 140 mm in X2 and 360 mm in Z2.
Up to 8 revolving tools, at 50 - 5,000 rpm, driven by a 2.8/1.0 kW motor. Turning tools are 20 mm Sq. and drill shanks 25 mm dia. That suits cross holes, small flats and tapping on bar parts.
Floor space is 2,350×1,450 mm, machine height 1,700 mm and weight 3,100 kg. Allow extra room for the bar feeder and chip handling, which the table does not include.
