MAKINO A-51NX HORIZONTAL MACHINING CENTER

Technical Description

The Makino A51NX is a 4-axis horizontal machining center engineered for high-performance production work. This compact machine features a robust casting design with large roller-type linear guides, delivering 22" X-axis, 25.2" Y-axis, and 25.2" Z-axis travel capabilities. The machine is powered by a high-speed, high-power 50 HP spindle operating at a maximum of 14,000 RPM with 303 Nm of torque, equipped with a CAT 40 tool taper (HSK-A63 optional). The full B-axis rotary indexing provides 0.001° precision, enabling complex multi-sided part machining without repositioning the workpiece. The 60-station automatic tool changer supports rapid tool-to-tool changes in just 0.9 seconds, with maximum tool diameter of 170mm and weight capacity of 12kg. The 15.7" x 15.7" pallet accommodates a maximum load of 880 pounds, making it suitable for mid-range component production. Rapid traverse rates reach 1,968 IPM on X and Y axes and 2,362 IPM on Z-axis, minimizing non-cut time. The Professional 5 Fanuc 31i CNC control integrates advanced features including Inertia Active Control for optimized axis acceleration and an integrated Broken Tool Sensor for automatic tool condition monitoring. High-pressure coolant delivery through the spindle ensures efficient chip evacuation and extended tool life. Weighing 20,000 pounds and measuring 167" x 107" x 107", this machine combines productivity and reliability for automotive and high-volume manufacturing applications.
