Our best estimate for the Makino a51nx is $250,000 - $350,000. This is an estimate for a horizontal machining centers (hmc) in this class, not a quote from Makino; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/makino-a51nx#price; the request is passed to Makino or an authorised dealer.
The a61nx steps up to 500 x 500 mm (19.7 in x 19.7 in) pallets and 730 mm (28.7 in) of X and Y with 800 mm (31.5 in) of Z, against 400 x 400 mm (15.7 in x 15.7 in) and 560 x 640 x 640 mm (22.0 x 25.2 x 25.2 in) on the a51nx. Both are 40-taper machines with a 14,000 rpm spindle as standard and 60,000 mm/min rapids.
Parts up to Ø 630 mm x 900 mm (Ø 24.8 in x 35.4 in) and 400 kg (880 lb), on a 400 x 400 mm (15.7 in x 15.7 in) pallet. The swing is larger than the pallet, so tombstones and angle plates with parts on several faces fit inside it.
60 as standard. Makino lists 40, 134, 219 and 311 tool magazines as options. Tools can be up to 430 mm (16.9 in) long with a CAT shank or 420 mm (16.5 in) with HSK, 170 mm (6.7 in) in diameter and 12 kg (26.4 lb).
Makino says the latest version of the Pro6 control includes Process Tracer and Feed Optimizer, new components of its iKnowledge software. The machine also has a health monitoring system that Makino says supports proactive maintenance.
The standard spindle runs to 14,000 rpm and a 20,000 rpm spindle is optional. The taper is CAT40, with HSK-63 also listed. Makino's short table gives no power or torque figures for either spindle, so ask for the curves before committing to steel roughing.
