Our best estimate for the Makino a81nx is $700,000 - $1,000,000. 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-a81nx#price; the request is passed to Makino or an authorised dealer.
The standard 10,000 rpm spindle keeps rapids at 50,000 mm/min (1,968 in/min) and suits mixed work. The optional 8,000 rpm High Torque spindle gives 50 HP continuous, aimed at heavy roughing of iron castings and hard metal aerospace parts, with rapids of 36,000 mm/min (1,417 in/min).
Parts up to Ø 1,000 mm x 1,300 mm (Ø 39.4 in x 51.2 in), on 630 mm x 630 mm (24.8 in x 24.8 in) pallets. Load is 1,200 kg (2,645 lb) as standard or 1,500 kg (3,307 lb) with the option. Makino credits an extra 100mm of Y stroke with 12.5% more work envelope than the previous model.
The a71nx is the 500 mm machine, with 500 x 500 mm (19.7 in x 19.7 in) pallets and 800 x 750 x 830 mm (31.5 x 29.5 x 32.7 in) travels. The a81nx steps up to 630 mm x 630 mm (24.8 in x 24.8 in) and 900 x 900 x 1,020 mm (35.4 x 35.4 x 40.2 in). Both have a 10,000 rpm CAT50 spindle as standard.
Tools up to 690 mm (27.2 in) long with CAT or HSK shanks, 356 mm (14.0 in) in diameter and 30 kg (66 lb), or 35 kg (77 lb) with the option. A tool loading station on every magazine ejects the tool into a rail-guided drawer for loading.
60 as standard, with 80, 136, 187 and 299-tool magazines as options. Tool-to-tool time is 1.7 sec with a 12 kg tool, and chip-to-chip is 3.7 sec.
