The Makino a61 is a 500mm, 40-taper horizontal machining center with a reputation for rigidity and thermal stability that has made it a staple in high-mix, fixtured-production and job-shop environments. This 2006 machine pairs a 12,000-rpm high-power CAT40 spindle (29.5 HP) with X/Y/Z travels of 28.7 x 25.6 x 31.5 inch, a full 4th-axis NC rotary table, and a 60-tool automatic tool changer for complex multi-side machining. It runs the Makino Professional 5 (Fanuc-based) control and is equipped with 300 psi through-spindle coolant, eight-nozzle and overhead shower coolant, a Renishaw MP700 spindle probe, automatic tool length measurement, a lift-up chip conveyor, and Daikin automatic lubrication. The twin-pallet automatic pallet changer (500mm / 19.7 inch pallets) supports pallet-to-pallet production, with a maximum workpiece envelope of 24.8 inch diameter by 35.4 inch.
Compared with the previous-generation Makino A-series horizontals it replaced, the a61 is a meaningful step up rather than just a newer build: it brought a larger 500mm pallet, a 12,000-rpm high-power spindle for stronger ferrous cutting, a full contouring 4th-axis NC rotary table, and the Professional 5 control with tool monitoring and high-speed machining features. Where older 40-taper HMCs were limited on rigidity, thermal growth, and part size, this a61 holds accuracy through long cycles and tackles bigger, more complex fixtured work. For a buyer, that means stepping into a production-grade Makino horizontal - high-power spindle, 4th axis, 60-tool ATC, probing, and through-spindle coolant already in place - instead of an older, less capable horizontal machining center.
