Overview

The Mazak UD-400/5X is a compact 5-axis vertical machining center with a trunnion-type rotary table, designed for high-precision simultaneous 5-axis machining of small-to-medium parts. The UD series targets medical device, aerospace component, and precision instrument manufacturing where tight tolerances, excellent surface finish, and efficient chip-to-chip times matter.

Axis travels measure 550 x 400 x 400 mm (21.7 x 15.7 x 15.7 in) in X/Y/Z, with the trunnion table providing A-axis tilting (-120 to +30 degrees) and C-axis rotation (360 degrees continuous). The 400 mm (15.7 in) table diameter accommodates workpieces up to approximately 400 mm diameter and 315 mm height, with a maximum workpiece weight of 150 kg (331 lb).

The direct-drive spindle reaches 20,000 RPM with 18.5 kW (25 hp) through a CAT 40 taper, optimized for high-speed cutting in aluminum, titanium, stainless steel, and other aerospace and medical-grade materials. Roller gear cam drives on both rotary axes provide backlash-free positioning for smooth simultaneous contouring.

Rapid traverse reaches 42 m/min across all linear axes. The 30-station ATC provides adequate tool storage for complex multi-feature parts. The MAZATROL SmoothAi CNC offers AI-based machining optimization. At approximately 7,500 kg (16,535 lb), the UD-400/5X has a compact footprint suitable for tight shop floor layouts.

Competitors include the DMG Mori DMU 40 eVo, Hermle C 250, Okuma MU-4000V, and Matsuura MX-330. New UD-400/5X machines price between $250,000 and $375,000.

Strengths & Limitations

Strengths

20,000 RPM direct-drive spindle enables high-speed finishing in aluminum, titanium, and medical-grade stainless steel
Compact footprint makes the UD-400/5X accessible for shops with limited floor space adding their first 5-axis capability
Roller gear cam drives on both rotary axes eliminate backlash for smooth simultaneous 5-axis contouring and consistent surface quality
SmoothAi control with AI-based optimization automatically adjusts cutting parameters for improved surface finish and tool life
42 m/min rapid traverse minimizes non-cutting time between features on complex multi-feature parts
Competitive pricing starting at $250,000 makes full 5-axis capability accessible to smaller shops

Limitations

150 kg maximum workpiece weight limits fixture complexity and restricts the machine to smaller parts
400 mm table diameter constrains workpiece size compared to larger 5-axis platforms like the VARIAXIS i-500
CAT 40 taper provides less rigidity than CAT 50 or HSK-A100 for heavy cuts in hardened steel and titanium roughing
30-tool standard ATC may be limiting for complex parts requiring many different tools

Best For

Medical device manufacturers machining orthopedic implants, surgical instruments, and precision components in titanium and stainless steel Aerospace component shops producing small structural brackets, fittings, and turbine components requiring full 5-axis contouring Precision instrument manufacturers machining complex housings, optical mounts, and sensor enclosures Job shops adding compact 5-axis capability for prototyping and short-run production of complex geometries Shops looking for an entry-level full 5-axis simultaneous machine with proven Mazak reliability and service support

Frequently Asked Questions

01 What does a Mazak UD-400/5X cost?

New UD-400/5X machines price between $250,000 and $375,000 depending on spindle configuration, ATC capacity, and options. This positions the UD-400/5X as one of the more accessible full 5-axis machines from a major builder.

02 How does the UD-400/5X compare to the VARIAXIS i-300?

Both are compact 5-axis machines targeting small parts. The UD-400/5X offers a slightly larger 400 mm table versus the VARIAXIS i-300's smaller platform, and uses roller gear cam drives. The VARIAXIS i-300 is part of the well-established VARIAXIS family. Both use CAT 40 spindles and SmoothAi controls. The choice often comes down to specific part requirements and pricing.

03 Can the UD-400/5X machine titanium?

Yes. The 20,000 RPM spindle provides good surface speeds for titanium cutting, and the rigid trunnion design handles the cutting forces. For heavy titanium roughing, the 18.5 kW spindle and 150 kg table load are the limiting factors. The UD-400/5X is well-suited to titanium finishing and light-to-moderate roughing on smaller parts.

04 What automation options are available?

The UD-400/5X can be paired with robot loading systems and pallet changers for unattended operation. Its compact footprint makes it suitable for cell configurations with collaborative robots. Expanding the ATC to 48 tools extends unattended run time.
