Our best estimate for the Citizen Miyano ABX-51THY2 is $350,000 - $460,000. 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-51thy2#price; the request is passed to Citizen Machinery or an authorised dealer.
36, spread over three turrets, and the table gives 36 as the maximum number of revolving tools as well. The two-turret Miyano ABX-51SYY2 holds 24. Each turret indexes in 0.25 sec per position.
The main spindle runs to 5,000 rpm on 15/11 kW with a 52 mm (2.05 in) bore. The sub-spindle also runs to 5,000 rpm, on 7.5/5.5 kW. Both take 51 mm bar work, a 165 mm power chuck and 125 mm of work length.
Same turret layout and 36 tools. The Miyano ABX-64THY2 takes 64 mm (2.52 in) bar through a 65.5 mm (2.58 in) bore with a 4,000 rpm main spindle, where the Miyano ABX-51THY2 takes 51 mm (2.01 in) bar at 5,000 rpm.
A 49 kVA supply with a 150 A fuse, 400 L of coolant, 10 L of hydraulic oil and 4 L of lubricant, and floor space of 3,290 × 2,204 mm (130 × 86.8 in) for a machine of 11,350 kg (25,022 lb).
No, Citizen does not list it in the current lineup. On a used machine, check how many of the 36 positions carry driven holders and confirm the control memory of 128 KB or 250 programs.
