The a61nx is a 500mm, 40-taper production horizontal machining center. The a51nx and a61nx share key machine technologies that take part productivity, accuracy and machine reliability to the next level. The 14,000-rpm high-speed, high-power spindle features 240 Nm of torque, well suited for automotive part production. Non-cut times are minimized through 1G axis acceleration and a standard direct-drive motor B axis. Robust casting design and roller-type linear guides ensure that the entire a61nx work envelope can be effectively utilized. The a61nx production machining center is available in a tall column (730mm) version for part applications that require larger strokes but do not need 50-taper spindles. Unique way-cover design, dual-supported tool-change arm and Makino spindle technology provide the foundation for industry-leading reliability.
