Our best estimate for the Citizen Miyano BND-51SY is $180,000 - $260,000. 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-bnd51sy#price; the request is passed to Citizen Machinery or an authorised dealer.
It is not in Citizen's current lineup. The current model in the series is the Miyano BND-51SY2, and the figures listed for the BND-51SY are the same as that machine's, so verify them on any BND-51SY you consider.
The listed maximum machining length is 320 mm (12.60 in). The turret has 435 mm (17.13 in) of Z travel and the second spindle a 530 mm (20.87 in) Z2 stroke, so long parts can be turned and transferred in one cycle.
A 12-station turret in which all 12 stations can hold live tools, listed at 5,000 rpm. The Y axis travels 75 mm (+40/-35 mm). Turning tools take 20mm Sq. shanks and the tool holes are 25mm Dia.
Confirm the control model, since the table lists only Mitsubishi CNC, and get the back-spindle motor rating, which the table does not give. Plan for approximately 4,500kg and a 20 m/min (787 ipm) rapid traverse.
