Machine Comparison
Makino a71nx vs Makino a81nx
Makino vs Makino · Horizontal Machining Centers
Summary
The Makino a71nx and Makino a81nx are both from Makino's horizontal machining centers lineup, making this a common upgrade or lineup decision for shops already invested in the Makino ecosystem. The Makino a71nx leads in max spindle speed (12,000 RPM (HSK-A100 optional) vs 10,000 RPM (14,000 RPM optional HSK-A63)). The Makino a81nx leads in x travel (900 mm (35.4 in) vs 750 mm (29.5 in)). The Makino a71nx leads in rapid traverse (60 m/min (2,362 ipm) vs 50 m/min (1,969 ipm)). These machines are closely matched across most specifications, making the decision more about specific feature priorities, dealer support, and your existing shop ecosystem than raw spec advantages. Both machines are proven performers in production environments and represent solid investments for shops in the market for a horizontal machining center.

Advantages
Makino a71nx
- Higher maximum spindle speed of 12,000 RPM (HSK-A100 optional) enables faster cutting on aluminum and non-ferrous materials
- Faster rapid traverse at 60 m/min (2,362 ipm) reduces non-cutting time between operations
- Lighter at ~16,000 kg (35,274 lb), potentially easier installation and lower foundation requirements
- More competitive pricing at $550,000 - $800,000 compared to $700,000 - $1,000,000
Makino a81nx
- Greater x travel of 900 mm (35.4 in) accommodates larger workpieces
- Greater y travel of 800 mm (31.5 in) accommodates larger workpieces
- Greater z travel of 900 mm (35.4 in) accommodates larger workpieces
- More spindle power at 37 kW (49.6 hp) continuous for aggressive material removal in harder materials
- Superior spindle torque at 700 Nm (516 ft-lb) vs 303 Nm (224 ft-lb)
Verdict
This is a close matchup. The Makino a71nx and Makino a81nx trade advantages across different specifications, making neither a clear winner on paper alone. Your decision should come down to practical factors: which dealer is closer, which control system your operators already know, what tooling ecosystem you're invested in, and which machine's specific strengths match your highest-volume work. Get quotes on both, run test cuts with your actual parts if possible, and factor in long-term service and support costs.
