Our best estimate for the Citizen Miyano BNA-42CY is $120,000 - $180,000. 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-bna42cy#price; the request is passed to Citizen Machinery or an authorised dealer.
Yes. Citizen describes the CY type as usable as a chucker machine, and the table lists 5" and 6" hollow chucks alongside collet chucks for bar work at the 42 mm dia. standard machining diameter.
No. The table lists one spindle and one tool post, a 12-station turret. Parts that need the cut-off face machined go to a second operation or to a two-spindle machine; for one-sided parts up to 200 mm long the single spindle is enough.
The spindle motor is rated 11/7.5/5.5 kW (15%/15min/cont.): 11 kW at 15% duty, 7.5 kW for 15 minutes and 5.5 kW continuous. The rotary tool motor is rated 2.8/1.0 kW and drives the tools at 50 - 5,000 rpm.
20 m/min on X and Z and 23 m/min on Y. The Y axis lets the rotary tools drill and mill away from the part centreline, so flats, cross holes and slots can be finished on the machine.
A 16 kVA supply, a floor area of W2,260×D1,433 mm and 1,745 mm of height; the machine weighs 3,220 kg. Add space for bar loading if it will run from bar rather than as a chucker.
