Makino a61NX-5E HORIZONTAL MACHINING CENTER

Technical Description

The 2017 Makino a61NX-5E is a compact five-axis horizontal machining center engineered for precision manufacturing of complex aerospace and small to mid-size components. This machine features a 15.7" x 15.7" pallet with generous axis travels: 28.7" on both X and Y axes, and 26.8" on the Z axis, enabling comprehensive workpiece accessibility. The rotary axes provide B-axis travel of 290° (−110° to +180°) and unlimited C-axis rotation, facilitating sophisticated multi-sided machining operations from a single setup. The spindle nose-to-B-axis center distance ranges from 3.9" to 30.7", offering flexibility in tool reach and part positioning. Equipped with a direct-drive rotary trunnion table and HSK-63A spindle taper, the machine delivers high-performance capabilities with spindle speeds up to 14,000 rpm standard and optional 24,000 rpm configurations. The standard high-torque spindle produces 240 Nm of duty-rated torque with 30 kW continuous output, while the structural spindle option generates 62.6 Nm torque with 80 kW output for aggressive metal removal. The machine features a 60-tool automatic tool changer with optional capacities up to 313 tools, chip-to-chip time of 2.5 seconds, and innovative thermal management for enhanced positioning accuracy. With linear acceleration of 1G on X and Y axes and 0.8G on Z, rapid traverse rates reach 2,362 ipm. The machine occupies a floor footprint of 114.5" x 204.2" and weighs 24,250 lbs, making it suitable for job shops and production environments requiring compact, high-precision five-axis machining.
