How much does the Mazak UD-400/5X cost?
Estimated price range
Our best estimate for a 5-axis machining center in this class — not a quote from Yamazaki Mazak. Configuration moves it a long way.
Overview
The Mazak UD-400/5X is a small, very high-speed 5-axis machining center: a 45,000 rpm HSK-E40 spindle over a 12.60 in (320 mm) × 12.60 in (320 mm) tilting table, with 22 in (559 mm) of X travel, 16 in (406 mm) of Y and 14 in (356 mm) of Z. The largest workpiece is Ø15.75 in (400 mm) × 11.81 in (300 mm) and the table carries 265 lb (120 kg). Every figure describes a finishing machine for small parts with free-form surfaces.
The spindle is rated 11 kW (15 HP) continuous and 13.8 kW (19 HP) at 40% ED, yet torque is only 4.1 ft-lb (6 Nm) continuous and 5.1 ft-lb (7 Nm) at 40% ED. Its power comes from speed, so the work is small cutters running fast and light. The tool limits say the same thing: Ø1 in (25 mm) in diameter, 8 in (203 mm) long and 4 lb (2 kg). A 40-tool magazine leaves room for duplicate finishing tools.
Much of the design is about holding size while that spindle runs for hours. The base and column are mineral castings, chosen for damping. Temperature-controlled cooling oil circulates through the spindle core and the housing. Direct drive motors turn the B and C axes without belts or gears, and scale feedback is fitted on X, Y, Z, B and C. THERMAL SHIELD compensates automatically for changes in room temperature, and MAZACHECK measures and offsets misalignment and tilt of the rotary axes.
The table tilts from -120° to +30°. Mazak's argument for the tilt is tool length: near-vertical walls that would need a long, slender tool on a 3-axis machine can be reached with a short one, and a ball end mill can be kept off its tip, where the cutting speed is zero. Linear rapids are 1,890 ipm (48 m/min). The machine is heavy for its envelope at 33,069 lb (15,000 kg), on a footprint of 117 in (2,972 mm) × 139 in (3,531 mm).

Strengths & Limitations
Strengths
- 45,000 rpm HSK-E40 built-in motor spindle, with cooling oil circulated through the spindle core and housing
- Mineral cast base and column to suppress vibration during high-speed operation
- Direct drive motors on the B and C axes, with scale feedback on the X, Y, Z, B and C axes
- 40-tool magazine on a machine with a 12.60 in (320 mm) × 12.60 in (320 mm) table
- THERMAL SHIELD compensation for room temperature changes and MAZACHECK measurement of the rotary axes
- Rapids of 1,890 ipm (48 m/min) on X, Y and Z
Limitations
- Spindle torque is 4.1 ft-lb (6 Nm) continuous and 5.1 ft-lb (7 Nm) at 40% ED, which rules out roughing with large cutters
- Tools are limited to Ø1 in (25 mm) in diameter, 8 in (203 mm) in length and 4 lb (2 kg)
- Table load is 265 lb (120 kg) and the largest workpiece is Ø15.75 in (400 mm) × 11.81 in (300 mm)
- Weighs 33,069 lb (15,000 kg), more than the VARIAXIS i-600 NEO at 28,660 lb (13,000 kg), so the floor has to be planned for a much larger machine than the work envelope suggests

Frequently Asked Questions
01
A built-in motor spindle with an HSK-E40 taper and a maximum speed of 45,000 rpm. It is rated 11 kW (15 HP) continuous and 13.8 kW (19 HP) at 40% ED, with torque of 4.1 ft-lb (6 Nm) continuous and 5.1 ft-lb (7 Nm) at 40% ED. Temperature-controlled oil cools the spindle core and the housing.
02
The maximum workpiece is Ø15.75 in (400 mm) × 11.81 in (300 mm) on a 12.60 in (320 mm) × 12.60 in (320 mm) table, with a table load of 265 lb (120 kg). Travels are 22 in (559 mm) in X, 16 in (406 mm) in Y and 14 in (356 mm) in Z, and the tilt range is -120° to +30°.
03
The magazine holds 40 tools. Each can be up to Ø1 in (25 mm) in diameter, 8 in (203 mm) long and 4 lb (2 kg). Those limits, together with 5.1 ft-lb (7 Nm) of torque at 40% ED, mean that roughing with larger cutters has to happen on another machine before the part arrives here.
04
Through several measures Mazak lists: mineral cast base and column for damping, cooling oil through the spindle core and housing, direct drive motors on the B and C axes, and scale feedback on the X, Y, Z, B and C axes. THERMAL SHIELD compensates automatically for room temperature changes, and MAZACHECK measures and offsets misalignment and tilt of the rotary axes.
05
The footprint is 117 in (2,972 mm) × 139 in (3,531 mm) with the MAZATROL SmoothX control, the height is 110 in (2,794 mm) and the weight is 33,069 lb (15,000 kg). That is a lot of mass for a machine with 22 in (559 mm) of X travel, so check the floor loading before choosing where it stands.
