Our best estimate for the Citizen Miyano BND-51SY2 is $200,000 - $290,000. 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-bnd-51sy2#price; the request is passed to Citizen Machinery or an authorised dealer.
Citizen gives a maximum machining diameter of 51 mm for bar work and a maximum machining length of 320 mm. The turret slide strokes are 175 mm in X and 435 mm in Z, so long parts can be turned from the bar without re-chucking.
The turret has 12 stations and Citizen lists a maximum of 12 revolving tools, so every station can be a driven one. Turning tools use 20 mm square shanks and the tool holes are 25 mm in diameter.
The turret's Y stroke is +40 mm/-35 mm. That lets driven tools drill and mill off the spindle centreline, for cross holes, flats and keyways, without a second machine. It is not long enough for wide milled faces.
Citizen's table lists a 530 mm stroke for an axis labelled B but gives no back-spindle speed, motor or chuck size. Ask Citizen what the B axis carries and what back-end work it supports before quoting jobs that need the cut-off end finished.
The Miyano BNA-42CY runs from 60 to 6,000 rpm and weighs 3,220 kg. The BND-51SY2 runs from 50 to 5,000 rpm and weighs approximately 4,500 kg, with 51 mm bar capacity and 320 mm machining length.
