Mazak UD-400/5X vs Mazak VARIAXIS C
Yamazaki Mazak vs Yamazaki Mazak · 5-Axis Machining Centers
Summary
The Mazak UD-400/5X and the Mazak VARIAXIS C are both 5-axis machining centers with an 11 kW (15 HP) continuous spindle, but they are built for different work. The Mazak UD-400/5X is a high-speed finishing machine for small, precise parts; the VARIAXIS C is a larger general-purpose machine for five-sided work.
The Mazak UD-400/5X spins to 45,000 rpm against 12,000 rpm, holds 40 tools against 30 tools, and rapids at 1,890 ipm (48 m/min) against 1,654 ipm (42 m/min). The VARIAXIS C has more room and muscle: 26 in (660 mm) to 34 in (864 mm) of X against 22 in (559 mm), 21 in (533 mm) of Z against 14 in (356 mm), a table load of 1,102 lb (500 kg) to 1,543 lb (700 kg) against 265 lb (120 kg), and 42 ft-lb (57 Nm) of continuous torque against 4.1 ft-lb (6 Nm).

Advantages
Mazak UD-400/5X
- 45,000 rpm HSK-E40 spindle against 12,000 rpm, for small ball end mills
- 40 tools against 30 tools
- 1,890 ipm (48 m/min) rapid traverse against 1,654 ipm (42 m/min)
Mazak VARIAXIS C
- Table load of 1,102 lb (500 kg) to 1,543 lb (700 kg) against 265 lb (120 kg)
- 42 ft-lb (57 Nm) continuous torque against 4.1 ft-lb (6 Nm)
- Larger envelope: 26 in (660 mm) to 34 in (864 mm) of X, 22 in (559 mm) to 24 in (610 mm) of Y and 21 in (533 mm) of Z, against 22 in (559 mm), 16 in (406 mm) and 14 in (356 mm)
Verdict
These two serve different jobs. Choose the Mazak UD-400/5X for finishing free-form surfaces on small, precise parts with small ball end mills, where 45,000 rpm and 40 tools matter more than torque. Choose the Mazak VARIAXIS C for five-sided machining of aluminum housings, brackets and heavier parts, where the larger envelope, a table rated to 1,543 lb (700 kg) and 42 ft-lb (57 Nm) of torque handle real stock removal.
