Our best estimate for the Makino a71nx is $550,000 - $800,000. 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-a71nx#price; the request is passed to Makino or an authorised dealer.
For tool size and torque. The a61nx is CAT40 at 14,000 rpm with 303 Nm, tools up to 205 mm (8.1 in) and 12kg (26.4 lb) and a 500 kg (1,100 lb) standard load. The a71nx is CAT50 at 10,000 rpm with 512 Nm (378 ft-lbs), 300 mm (11.8 in) and 20 kg (44.1 lb) tools and 1,000 kg parts, on the same 500 x 500 mm (19.7 in x 19.7 in) pallet.
Makino rates the 10,000 rpm spindle at 37kW (49.6HP) of duty-rated power and 512 Nm (378 ft-lbs) of duty-rated torque. The taper is CAT50 as standard, with HSK-A100 optional.
The standard direct-drive NC rotary table indexes 90° in 1 second. It also supports Inertia Active Control, which estimates the fixture weight from B-axis motor load and adjusts acceleration and deceleration of the B and Z axes to match.
The 1.7 sec tool-to-tool and 3.6 sec chip-to-chip figures are for tools up to 20 kg. Tools up to 30 kg (66 lb) are possible with limitations, and the table does not give change times for them.
The a81nx moves to 630 mm x 630 mm (24.8 in x 24.8 in) pallets and 900 x 900 x 1,020 mm (35.4 x 35.4 x 40.2 in) travels, with the same 10,000 rpm CAT50 spindle as standard. The a71nx has 800 x 750 x 830 mm (31.5 x 29.5 x 32.7 in) on a 500 x 500 mm (19.7 in x 19.7 in) pallet.
