Citizen Miyano ABX-80SYY vs Citizen Miyano ABX-80THY
Citizen Machinery vs Citizen Machinery · CNC Lathes
Summary
The Citizen Miyano ABX-80SYY and ABX-80THY are two versions of the same large turning center. They share 190 mm (7.48 in) of X travel, 80 mm of Y travel, a 350 mm (13.78 in) chuck-work diameter, 250 mm (9.84 in) of turning length, 80 mm (3.15 in) bar capacity and an 18.5 / 15 kW (25 / 20 HP) main spindle. The headline difference is the third turret: the THY carries 36 tools against 24 and lists 13+ axes against 10.
The ABX-80THY also turns faster, with a 4,000 RPM main spindle against 3,500 RPM and a 5,000 RPM sub-spindle against 3,500 RPM. The ABX-80SYY runs a Mitsubishi M80W dual-path control where the THY uses FANUC, and it is the lighter machine at 10,900 kg against 11,300 kg.

Advantages
Citizen Miyano ABX-80SYY
- Two-turret, 10-axis layout for parts that do not need a third tool group
- Mitsubishi M80W dual-path control for shops already programming Mitsubishi
- Lighter at 10,900 kg against 11,300 kg
Citizen Miyano ABX-80THY
- 36 tools across three turrets against 24
- 4,000 RPM main spindle against 3,500 RPM
- 5,000 RPM sub-spindle against 3,500 RPM
- FANUC control for shops serving Tier 1 suppliers on FANUC
Verdict
Both machines handle the same 80 mm bar work in the same envelope, so the choice comes down to tooling and control. Choose the ABX-80THY for complex, high-volume parts that need 36 tools for unattended runs, faster main and sub-spindles, or a FANUC control. Choose the ABX-80SYY when 24 tools on two turrets cover the part family and the shop already runs Mitsubishi controls.
