Makino a51nx
High Productivity Horizontal Machining Center

The a51nx is a 400mm horizontal machining center from Makino that builds on the highly successful a51 platform. Key technologies on the machine advance part productivity, accuracy and machine reliability to the next level. The 14,000 RPM high speed, high power spindle features 240 Nm of torque. This spindle is well suited for ferrous and non ferrous 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 a51nx work envelope can be effectively utilized. One piece way covers (X & Z), dual supported tool change arm and Makino spindle technology provide the foundation for industry leading reliability.
