Overview
The Mazak VCU-400A 5X is a compact simultaneous 5-axis vertical machining center designed for precision machining of small-to-medium parts in aerospace, medical, and general precision manufacturing. The machine uses a trunnion-style rotary/tilt table that provides full simultaneous 5-axis capability in a compact footprint.
Axis travels measure 550 x 400 x 400 mm (21.7 x 15.7 x 15.7 in) with a 400 mm (15.7 in) diameter rotary table rated for 200 kg (441 lb) workpiece loads. The A-axis tilts from +30 to -120 degrees with the C-axis providing 360-degree continuous rotation. The standard spindle runs at 12,000 RPM with 11 kW (15 hp) through a CAT 40 taper, with optional 18,000 RPM and 25,000 RPM high-speed spindles available for aluminum and non-ferrous high-speed machining.
The VCU-400A 5X features roller gear cam drives on both rotary axes, eliminating backlash while maintaining smooth motion during simultaneous contouring. Rapid traverse hits 36 m/min (1,417 ipm) on linear axes. The 30-tool ATC covers most job requirements, with 48 and 60-tool options available.
This is an entry-level to mid-range 5-axis platform positioned below the VARIAXIS series in capability and price. New VCU-400A 5X machines start around $200,000 to $325,000 depending on spindle and options. The machine competes with the DMG Mori CMX 50 U, Haas UMC-500, and Hermle C 250 in the compact 5-axis segment.

Strengths & Limitations
Strengths
- Compact footprint delivers full simultaneous 5-axis capability without consuming the floor space of larger VARIAXIS models
- Roller gear cam drives on both rotary axes eliminate backlash and provide smooth motion during simultaneous contouring operations
- Entry-level pricing from $200,000 makes genuine 5-axis machining accessible to smaller shops stepping up from 3-axis or 3+2 machining
- Multiple spindle options from 12,000 to 25,000 RPM allow shops to configure the machine for their primary material mix
- MAZATROL SmoothG control with conversational programming reduces the barrier to entry for operators new to 5-axis work
- Lightweight 7,500 kg machine installs on standard shop floors without specialized foundations
Limitations
- 550 x 400 x 400 mm travel limits this machine to small-to-medium parts; anything beyond 400 mm diameter needs a larger platform
- 200 kg table load is light compared to the VARIAXIS i-700 at 600 kg, constraining fixture mass and part weight
- 11 kW standard spindle is underpowered for aggressive roughing in steel and titanium; high-speed options add significant cost
- 30-tool standard ATC is tight for complex 5-axis parts with many tool changes; expanding to 60 tools adds $15,000-$25,000
- CAT 40 only limits heavy-duty cutting capability compared to machines offering CAT 50 or HSK-A63 options

Frequently Asked Questions
01
New VCU-400A 5X machines start around $200,000 for a base configuration with 12,000 RPM spindle and 30-tool magazine. Adding the 25,000 RPM spindle, expanded ATC, probing, and high-pressure coolant pushes pricing to $275,000-$325,000. Used VCU-400A machines from 2018-2022 trade around $120,000-$180,000.
02
The VARIAXIS i-300 is the next step up with a more rigid platform, longer axis travels, and the full VARIAXIS construction quality. The VCU-400A 5X is the more affordable entry point with similar 5-axis geometry but lighter construction. For production 5-axis work demanding tight tolerances over long runs, the VARIAXIS is worth the premium.
03
Yes. This is a full simultaneous 5-axis machine, not a 3+2 indexing machine. The roller gear cam drives on both rotary axes provide smooth interpolation during continuous 5-axis contouring. The SmoothG control handles 5-axis tool center point (TCP) control and collision avoidance.
04
The standard 11 kW spindle is too light for serious titanium roughing. With the higher-power spindle options, the machine handles titanium finishing and light roughing on small parts. For aggressive titanium work, a VARIAXIS or larger 5-axis with CAT 50 is a better choice.
05
The VCU-400A 5X supports robotic part loading through the front door and can be integrated into multi-machine cells. It does not have a built-in pallet changer like the VARIAXIS series. For unattended production, shops typically pair it with a robot arm and expanded tool magazine.
