Our best estimate for the Makino a91nx is $900,000 - $1,400,000. 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-a91nx#price; the request is passed to Makino or an authorised dealer.
The a91nx has an 800 x 800 mm (31.5 in x 31.5 in) pallet, 1,400 mm (55.1 in) of X and 1,200 mm (47.2 in) of Y, with 60,000 mm/min (2,362 ipm) rapids and 60 tools standard. The a92 has an 800 x 1,000 mm (31.5 in x 39.4 in) pallet, 1,520 mm (59.8 in) of X and 1,250 mm (49.2 in) of Y, rapids at 50,000 mm/min (1,969 ipm) and starts at 40 tools. Both have 1,350 mm (53.1 in) of Z.
The standard spindle runs to 10,000 rpm. Makino lists 8,000 rpm and 15,000 rpm spindles as the alternatives. The taper is CAT50, with HSK-A100 as the other shank. Makino's specification table does not give power or torque for these spindles, so ask for the curves before choosing one.
The workpiece envelope is Ø 1,450 x 1,450 mm (Ø 57.1 in x 57.1 in) on an 800 x 800 mm (31.5 in x 31.5 in) pallet. Maximum workpiece weight is 2,000 kg (4,400 lb.), with 3,000 kg (6,600 lb.) listed as the higher rating. The weight figure should include the fixture.
Tools can be up to 900 mm (35.4 in) long with a CAT or an HSK shank and up to ∅ 356 mm (Ø 14.0 in) in diameter. Tool weight is 30 kg (66 lb.) with the standard 60 tool magazine and 35 kg (77 lb.) with the 185 or 297 tool ATC.
Makino lists a tool-to-tool time of 1.8 sec, with 2.2 sec given in brackets. The table does not say which magazine or tool weight the slower figure belongs to, so confirm it for the magazine you plan to order.
