Our best estimate for a horizontal machining centers (hmc) in this class — not a quote from Makino. Configuration moves it a long way.

Overview

The Makino a71nx puts a 50-taper spindle on a 500 x 500 mm (19.7 in x 19.7 in) pallet horizontal machining center. Its 10,000 rpm CAT50 spindle, with HSK-A100 optional, is rated at 37kW (49.6HP) of duty-rated power and 512 Nm (378 ft-lbs) of duty-rated torque, and the machine travels 800 mm (31.5 in) in X, 750 mm (29.5 in) in Y and 830 mm (32.7 in) in Z.

Makino's own a61nx pairs the same pallet size with a 40-taper spindle. The a71nx keeps the compact pallet but takes the heavier tooling, longer reach and higher torque of a 50-taper spindle. The table allows tools up to 300 mm (11.8 in) in diameter and 20 kg (44.1 lb), or 30 kg (66 lb) with limitations. Makino lists ferrous, non-ferrous and hard metal applications for it. Parts can swing Ø 900 mm x 1,000 mm (Ø 35.4 in x 39.4 in) and weigh up to 1,000 kg, double the 500 kg standard rating of the 40-taper a61nx on the same pallet size.

Non-cut time gets attention too. The direct-drive NC rotary table is standard and indexes 90° in 1 second. It also feeds Inertia Active Control, which reads the B-axis motor load, estimates fixture weight and tunes acceleration of the B and Z axes. Makino quotes a 20% cut in tapping time over the previous model from the spindle's start and stop response. Rapids are 50,000 mm/min (1,968 ipm) on X and Y and 60,000 mm/min (2,362 ipm) on Z.

Tool changes take 1.7 sec tool-to-tool and 3.6 sec chip-to-chip for tools up to 20 kg. The magazine holds 60 tools as standard, with 136, 187 and 299 listed in brackets as larger options. A Vision type Broken Tool Sensor in the ATC magazine is standard.

Strengths & Limitations

Strengths

CAT50 spindle rated 37kW (49.6HP) and 512 Nm (378 ft-lbs) duty-rated on a compact 500 x 500 mm (19.7 in x 19.7 in) pallet
Workpieces up to 1,000 kg and Ø 900 mm x 1,000 mm (Ø 35.4 in x 39.4 in)
Standard direct-drive NC rotary table indexes 90° in 1 second
1.7 sec tool-to-tool and 3.6 sec chip-to-chip with tools up to 20 kg
Tools up to 300 mm (11.8 in) in diameter and 20 kg (44.1 lb), or 30 kg (66 lb) with limitations

Frequently Asked Questions

01 Why choose the a71nx over the a61nx?

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.

02 What power and torque does the a71nx spindle have?

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.

03 How fast does the a71nx index?

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.

04 When does the a71nx's 1.7 sec tool change apply?

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.

05 How does the a71nx compare with the larger a81nx?

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.
