Our best estimate for the Citizen Miyano BNX-51MSY is $220,000 - $320,000. 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-bnx51msy#price; the request is passed to Citizen Machinery or an authorised dealer.
The main spindle takes 51 mm (2.0 in) bar through a 52 mm bore and a 6" thru-hole chuck. The back spindle takes 42 mm (1.65 in) through a 43 mm bore and a 5" thru-hole chuck. Both run to 5,000 rpm.
The maximum machining length is 100 mm (3.94 in), so this is a short-part machine. The distance between the spindle end faces is 892 mm, which is the room the back spindle has to approach and pick off the part.
12 live tool stations running at up to 6,000 rpm on a 4.0 kW (25 Nm) motor, with 80 mm (+/-40 mm) of Y travel. Turning tools are □20 mm and boring sleeves φ25 mm.
Plan for 11,687 lb (5,300 kg), a footprint of 2,630 × 1,540 mm (104 × 60.6 in), 1,775mm of height and a 33 KVA / 100 A supply. The coolant tank holds 300 L.
