Overview
The Miyano ABX-80THY takes bar work to 80 mm (3.15 in) on its main spindle and 65mm Dia. on its second spindle, and machines it with three 12-station turrets that each have a Y axis. Both spindles are rated 18.5 / 15 kW (25 / 20 HP). Citizen's current lineup does not include the ABX-80THY, so a buyer will usually be assessing a used machine.
The main spindle runs to 4,000 RPM and the second spindle to 5,000 RPM. At 80 mm (3.15 in) the spindle limit rarely matters for turning the full bar diameter; it matters more for small features at the end of the part, where the second spindle's higher speed helps. With matched motors, roughing does not have to stay on the main side.
Tooling capacity is the strong point: 36 stations, any of which can hold a revolving tool, driven to 6,000 RPM. Every turret moves 190mm in X and 80 (±40) mm in Y. Turret 2 reaches 550mm in Z, and turrets 1 and 3 270mm each. Rapids are 20 m/min on X, 30 m/min on Z and 12 m/min on Y, and the Zs axis has a 756mm stroke with 1031mm between spindle faces.
Chuck work is listed to 350 mm (13.78 in) in diameter and 250 mm (9.84 in) in length, with 6-inch power chucks. The ABX-80THY weighs 11,300kg, needs 3,260×2,200mm of floor and stands 2,210mm tall; the control is listed as FANUC.
