Makino A-71 HORIZONTAL MACHINING CENTER

The 2008 Makino A-71 is a precision horizontal machining center engineered for high-volume production of ferrous and non-ferrous components. This machine features a robust 3-axis configuration with travels of 28.7" x 28.7" x 31.5" (X, Y, Z), accommodating workpieces up to ø35.4" x 39.4" with a maximum payload of 1,540 lbs. The machine is equipped with a 10,000 RPM spindle delivering 40 HP of duty-rated power and 512 Nm of torque, enabling efficient material removal across diverse applications. The CAT 50 taper (HSK-A100 optional) provides exceptional tool holding rigidity and precision. This machining center incorporates a Fanuc 31iM CNC control system for intuitive operation and advanced programming capabilities. The dual-pallet system, each measuring 19.7" x 19.7", enables continuous production workflow through seamless pallet indexing while one part is being machined. The 60-station automatic tool changer delivers rapid tool changes with 1.7-second tool-to-tool and 3.6-second chip-to-chip exchange times, minimizing non-productive downtime. The machine's rigid casting design and roller-type linear guides support full spindle utilization for consistent surface finishes and dimensional accuracy. Additional features include rapid traverse rates of 1,968 ipm on X/Y axes and 2,362 ipm on the Z-axis, supporting efficient cycle times. A direct-drive NC rotary table with 360° continuous B-axis capability enables multi-face machining without secondary operations. The integrated center trough efficiently manages high chip volumes during continuous machining, enhancing reliability and reducing maintenance intervals.
