Our best estimate for the Citizen Miyano BNA-42MSY is $170,000 - $250,000. 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-bna42msy#price; the request is passed to Citizen Machinery or an authorised dealer.
It lets the 8-station turret stop between its stations, giving 16 effective positions. All 8 stations are live, running to 6,000 RPM, with the live tool drive rated 1.0 kW (12 Nm).
As standard the sub spindle takes 34 mm (1.34 in), and 42 mm is listed as an option. The main spindle takes 42 mm (1.65 in). On a used machine, check which sub spindle was fitted before planning full-diameter transfers.
The Miyano BNA-42DHY has two turrets, an 8-station upper and a 6-station lower, runs revolving tools to 5,000 RPM and weighs 3,100kg. The BNA-42MSY has an 8-station half-indexing turret with 16 effective positions, live tools to 6,000 RPM and a weight of 3,000kg.
X1 140 mm (5.51 in), Z1 235 mm (9.25 in), Y1 70 mm (+/-35 mm), X2 129 mm (5.08 in) and Z2 360 mm (14.17 in). Rapids are 20 m/min (787 ipm) on X1, Z1 and Z2 and 12 m/min (472 ipm) on Y1 and X2.
