Our best estimate for the Citizen Miyano BNA-42S is $120,000 - $180,000. This is an estimate for a cnc lathes / turning centers 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-bna-42s#price; the request is passed to Citizen Machinery or an authorised dealer.
Yes. The sub-spindle takes parts up to 34 mm (1.34 in), runs 50 - 5,000 RPM on 5.5/3.7 kW (7.5/5 hp) and travels 310 mm (12.20 in) on its own axis. The main spindle takes 42 mm (1.65 in) bar.
The Miyano BNA-42SY5 has a 12-station Y-axis turret, 140 mm (5.51 in) of X travel and weighs 3,650 kg (8,047 lb). The Miyano BNA-42S has one turret without Y, 135 mm (5.31 in) of X travel and weighs 2,800 kg.
Eight live tool stations, rated at 5,000 rpm and 2.8 / 1.0 kW with 16 Nm of torque. Without a Y axis they drill and mill on the spindle centreline or across it, not off-centre.
A 28 kVA, 100 A electrical supply, 43.5 gal. of coolant and a footprint of 2,150 × 1,290 mm (84.6 × 50.8 in), with 1,660 mm of height. The machine weighs 6,173 lb (2,800 kg).
It is not in Citizen's current lineup. When looking at a used one, check the spindle bores, listed as 43 mm main and 30 mm sub, and the live tool fit-out against what your parts need.
