The Makino a51nx is a 400mm horizontal machining center that builds on the highly successful a51 platform with key high performance machining technologies that take productivity, accuracy and machine reliability to the next level.
The 14,000-rpm high-speed, high-power spindle features 240 Nm of torque, making it well suited for ferrous and non-ferrous part production.
1G axis acceleration and a standard direct-drive motor B-axis minimizes non-cut times, whereas a robust casting design and roller-type linear guides ensure the entire a51nx work envelope can be effectively utilized.
Additionally, one-piece way covers (X and Z) and a dual-supported tool-change arm provide the foundation for industry-leading reliability and high performance machining capability.
