Overview
The Citizen Miyano ABX-51THY2 is a 51 mm (2.01 in) twin-spindle turning centre with three turrets and room for 36 tools, all of which may be revolving tools. Main spindle and sub-spindle each run to 5,000 rpm, each takes a 165 mm (6.50 in) power chuck, and each handles a maximum work length of 125 mm (4.92 in). It is not part of Citizen's current lineup.
Thirty-six tools is a lot of capacity for parts of this size. It means a family of similar parts can stay tooled up together, and a part that needs turning, cross drilling, milled flats and threading on both ends can be finished without sharing positions. Each turret indexes in 0.25 sec per position, the revolving tools run to 6,000 rpm with 40 Nm maximum from an AC 4.5 kW motor, and turning tools use 20 mm square shanks.
The Miyano ABX-51SYY2 is the two-turret version, with 24 tools, a 30 m/min Z rapid and a weight of 10,900 kg (24,030 lb). On this three-turret machine Z moves at 20 m/min, X at 16 m/min and Y at 12 m/min. The control is a FANUC 31i-B with 128 KB of storage, or 250 programs, double the 64 KB the two-turret version lists.
Power comes from a 15/11 kW main spindle motor and a 7.5/5.5 kW sub-spindle motor, through a 52 mm (2.05 in) main spindle bore. Installation needs a 49 kVA, 150 A supply, a 400 L coolant tank and space for a 3,290 × 2,204 mm (130 × 86.8 in) footprint at 11,350 kg (25,022 lb).

Frequently Asked Questions
01
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.
02
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.
03
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.
04
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).
05
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.
