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.
