Our best estimate for the Citizen Miyano ABX-51SYY2 is $250,000 - $340,000. 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-abx-51syy2#price; the request is passed to Citizen Machinery or an authorised dealer.
In capacity, yes. Both take 51 mm bar work, a 165 mm power chuck and a 125 mm maximum work length, and both run to 5,000 rpm. They differ in power: the main spindle is rated 15/11 kW and the sub-spindle 7.5/5.5 kW.
The Miyano ABX-51THY2 has three turrets, 36 tools, a 20 m/min Z rapid and weighs 11,350 kg (25,022 lb). The Miyano ABX-51SYY2 has two turrets and 24 tools, moves Z at 30 m/min and weighs 10,900 kg (24,030 lb).
The main spindle is listed for H-S22/177E collets and the sub-spindle for H-S22 / DIN177E, both actuated by hydraulic cylinder. A 165 mm power chuck can be fitted on either spindle for chucked work.
Revolving tools run to 6,000 rpm with 40 Nm maximum torque from an AC 4.5 kW motor, and up to 24 can be mounted on the two turrets. Turret indexing takes 0.25 sec per position.
Citizen does not list it in the current lineup. On a used machine, confirm the turret tooling and the control memory, listed here as 64 KB or 125 programs on a FANUC 31i-B.
