Our best estimate for the Citizen Miyano BNJ-42 is $200,000 - $280,000. 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-bnj42#price; the request is passed to Citizen Machinery or an authorised dealer.
The Miyano BNJ-42 has a spindle slide with 85mm of X2 and 590mm of Z2 and a Mitsubishi M80W dual-path control. The Miyano BNE-42 is listed with a Mitsubishi M80 control and weighs 7,800kg, against 5,300 kg for the BNJ-42.
The table gives the HD2 position revolving tools to 3,000min-1, drilling to 10mm Dia. and tapping to M10×1.0. That covers cross holes, back-face drilling and small threads; larger holes and M12×1.75 taps belong on the HD1 turret.
The main spindle takes H-S22 or DIN177E collets, the second spindle JPN, H-S16 or DIN171E collets. Power chucks are hollow, 6" on the main spindle and 5" on the second spindle.
2,840×1,560mm without the chip conveyor, with a machine height of 1,700mm and a weight of 5,300 kg. Leave room beyond that for the conveyor and for bar loading at the main spindle.
