Our best estimate for the Citizen Miyano BNC-42 is $80,000 - $120,000. 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-bnc42#price; the request is passed to Citizen Machinery or an authorised dealer.
Citizen does not list the BNC-42 under that name in its current lineup. The table on this page is the BNC-42C7 column of Citizen's BNC series page. A used BNC-42 may be an earlier generation, so check the nameplate and the machine's own documentation.
Maximum bar work is 42 mm in diameter. The spindle runs from 60 to 6,000 rpm on a 7.5/5.5 kW motor rated for fifteen minutes and continuous duty, with a special flat type spindle nose for a 5-inch or 6-inch hollow chuck or collets.
It can. Up to 8 revolving tools are listed, running at 50 - 5,000 rpm on a 2.8/1.0 kW motor, but they are marked optional. Confirm that a particular machine has them before planning milled flats or cross holes.
The 8-station turret takes square turning tools with 20 mm shanks and drill shanks of 25 mm or 32 mm diameter. It indexes at 0.2 sec per station, driven by an AC servo motor and clamped by a curvic coupling.
It needs 2,272×1,270 mm of floor space, stands 1,686 mm high and weighs 2,400 kg. Allow extra length behind the spindle for a bar feeder if the machine will run from bar stock.
