Citizen Miyano ABX-65THY

The Citizen Miyano ABX-65THY is a large-bore fixed-headstock CNC lathe with a unique triple-turret configuration and Y-axis capability, designed for maximum multi-tasking productivity on complex parts up to 65mm bar diameter. The 'THY' designation indicates three turrets with Y-axis—the most turret stations available on any machine in the Miyano lineup. This configuration enables three simultaneous cutting operations, pushing cycle time reduction beyond what even twin-turret machines can achieve.

The triple-turret design assigns turrets to both the main spindle and sub-spindle, with the third turret providing additional machining capability that can work on either spindle depending on the cycle structure. This arrangement enables complex overlapping operations—for example, rough turning on the main spindle while simultaneously finish turning and cross-drilling on the sub-spindle. The Y-axis capability allows off-centerline features on multiple turrets simultaneously.

The ABX-65THY's main spindle reaches 4,500 RPM with a 15 kW motor, matched by a capable sub-spindle for balanced front and back operations. Live tooling across all three turrets provides extensive milling, drilling, and tapping capability—with up to 36 tool positions total, the machine accommodates the most complex parts without tooling compromise. The Mitsubishi M80W control manages the multi-path synchronization required for three-turret coordination.

Citizen's Miyano construction philosophy is pushed to its limits on the ABX-65THY. Managing thermal stability with three turrets cutting simultaneously generates substantial heat, and the thermally symmetric design must maintain accuracy under these extreme conditions. The rigid box-way construction on all axes provides vibration damping across all three cutting zones.

The ABX-65THY is a specialized production machine for shops that produce complex parts in high volumes where every second of cycle time matters. The triple-turret configuration is not about flexibility—it's about maximum simultaneous processing speed. Shops producing automotive powertrain components, complex hydraulic manifolds, and multi-feature aerospace parts see the most dramatic cycle time reductions.
