Makino a61nx Production Machining Center

The a61nx is a 500mm, 40-taper production horizontal machining center. The a61nx machine technologies 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.

Higher Machine Strength and Rigidity

Casting design and axis guide improvements of the nx machines deliver higher stiffness, load capacities and precision. A new crossed roller guide design yields improved rigidity for higher metal-removal rates, reduced vibration and improved tool life. Several major casting enhancements coupled with the use of cross roller guides enable customers to effectively use the additional 14 percent Y-stroke.

Improved Productivity

The nx machines are designed with a 1G-axis acceleration supplemented by high-power servo motors and enhanced casting rigidity for faster acceleration. Additionally, nx models have a standard Direct Drive (DD) motor B-axis table for dramatically faster indexing time over the previous worm-gear-driven NC rotary table (NCRT). The motor includes an inertia control system that adjusts table speed and acceleration based on pallet payload. Due to the speed of the DD motor, may lead to fewer machines required in high-volume, high-tool-count automotive applications. The DD motor table also reduces B-axis complexity and eliminates backlash and key component wear.

Expanding Reliability

Makino’s a-series machines have a reputation for reliability as well as low maintenance. The nx machines leverage this proven design to advance reliability with new features. The ATC shutter door typically sees millions of cycles over the life span of a machine. On nx machines, a high-speed servo-driven ball screw actuates the ATC shutter door, improving responsiveness, ease of setup and maintenance. The servo axis also reduces exposure of the ATC to the work envelope. The net result is improved reliability and cleaner ATC environments.
