MAKINO A51NX HORIZONTAL MACHINING CENTER

Technical Description

The Makino A51NX is a high-performance 4-axis horizontal machining center designed for precision and production efficiency. It features a 15.7" x 15.7" pallet table supporting up to 1,100 lbs, with an optional rotary table for enhanced versatility. The machine’s travel axes include 22" in X, 25.2" in Y, and 25.2" in Z, with rapid traverse rates up to 2,362 inches per minute, enabling fast and accurate positioning. Its spindle is horizontal with a CAT40 taper (optional HSK63A) and operates at speeds up to 14,000 RPM, powered by a 25 HP motor (optional 29 HP) capable of high torque for demanding machining tasks. The tool changer is a 60-station automatic tool changer (ATC) with rapid tool change times of 0.9 seconds and chip-to-chip times of 2.2 seconds; expanded ATC capacities up to 313 tools are available. A dual-pallet changer system is standard, facilitating continuous machining and reduced downtime. The B-axis offers full 360° rotation, supporting complex machining operations and flexibility. The machine incorporates advanced features such as high-pressure coolant through spindle, Professional 5 CNC control (Fanuc 31i), and robust construction with large roller-type linear guides ensuring rigidity and precision. It is optimized for automotive and high-volume production, with technologies like Inertia Active Control to enhance motion control and reduce non-cut time by up to 20%. The A51NX also includes a vision-type broken tool sensor for reliability and automated tool condition monitoring. Overall, the Makino A51NX combines high-speed cutting, accurate multi-axis motion, and durable build quality to deliver efficient, precision machining in a broad range of manufacturing environments.
