Our best estimate for the Citizen Miyano BNJ-51SY6 is $280,000 - $390,000. 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-bnj-51sy6#price; the request is passed to Citizen Machinery or an authorised dealer.
The Y axis of ±40 mm is on the turret slide of HD1, the 12-station upper turret, which also travels 165 mm in X1 and 246 mm in Z1. HD2 is the eight-station lower turret; SP2 moves on its own slide in X2 (85 mm) and Z2 (590 mm).
HD1 takes max. 12 revolving tools at 6,000 rpm and HD2 max. 4 at 3,000 rpm. The table lists revolving tools as an option (OPT), so check how many driven holders come with the machine.
SP1 machines 51 mm dia. and SP2 42 mm dia. SP1 takes H-S22 and DIN177E collet chucks, SP2 JPN, H-S16 and DIN171E. Power chucks are 6"/5" hollow.
The Miyano BNE-51SY6 has the same 51 mm dia. and 42 mm dia. spindle capacities but two 12-station turrets with 12+12 revolving tools, and weighs 7,800 kg. The BNJ-51SY6 is the lighter machine at 5,300 kg, with a smaller lower turret and a sliding SP2.
