⚙️ Citizen Miyano ABX 51 SYY2 Twin-Spindle CNC Turning Centre.

Precision Engineering Without Compromise. The Citizen Miyano ABX 51 SYY2 represents one of the most capable twin-spindle fixed-head CNC turning centres available for high-volume precision manufacturing. Combining Japanese-built reliability, an exceptionally rigid machine platform and advanced multi-axis machining capability, the ABX is engineered to reduce cycle times while maintaining exceptional accuracy, repeatability and reliability.

Manufactured around a 12-ton one-piece Meehanite casting with precision hand-scraped box guideways, the ABX delivers outstanding damping characteristics, thermal stability and cutting performance. This robust construction allows heavy-duty roughing and precision finishing operations to be completed on a single platform while maintaining micron-level accuracy over extended production runs.
Designed for complete one-hit machining, the machine combines twin opposed spindles, twin Y-axis turrets, advanced live tooling and simultaneous machining technology, making it ideal for complex components where productivity is critical.
