Overview

The Haas UMC-400 is the entry point into the Haas 5-axis universal machining center lineup, offering simultaneous 5-axis capability in a compact package with 432 x 279 x 330 mm (17 x 11 x 13 in) of linear travel. The trunnion-table design uses B-axis tilt and C-axis rotation to present the workpiece to a vertical spindle, which is the most common and intuitive 5-axis architecture for shops stepping into multi-axis work.

The spindle is an 11.2 kW (15 hp) inline direct-drive unit running to 8,100 RPM with 62 Nm (46 ft-lbf) of torque at 1,700 RPM. The CT/BT 40 taper accepts standard tooling, which means shops already running 40-taper VMCs can share tooling with the UMC-400. Air/oil injection bearing lubrication keeps the spindle running clean.

The trunnion carries a 230 mm (9.1 in) platter with a 45.4 kg (100 lb) capacity. The B-axis tilts from +120 degrees to -45 degrees with 407 Nm continuous torque and 576 Nm brake torque. The C-axis provides full 360-degree rotation with 285 Nm continuous torque and 271 Nm brake torque. Maximum part swing is 368 mm (14.5 in). These specs define the UMC-400 as a small-parts machine for medical devices, dental components, watch parts, and precision instrumentation.

The 30+1 SMTC posts 2.8-second tool-to-tool and 3.6-second chip-to-chip times, which is fast enough to keep cycle times competitive on multi-tool jobs. Rapids run at 22.9 m/min (900 ipm) on all three linear axes. At 3,411 kg (7,520 lb), the UMC-400 fits in shops with limited floor space. The machine requires only 220 VAC at 40 amps. For shops that need to start producing 5-axis parts without a six-figure investment, the UMC-400 delivers Haas reliability and support at the lowest entry price in the UMC series.

Strengths & Limitations

Strengths

Lowest entry price in the Haas UMC series makes 5-axis machining accessible for smaller shops
30+1 SMTC with 2.8-second tool-to-tool keeps cycle times competitive on multi-tool medical and dental parts
Compact 3,411 kg footprint fits shops with limited floor space that cannot accommodate larger 5-axis machines
40-taper tooling compatibility means existing Haas VMC shops can share tooling inventory
Full simultaneous 5-axis capability, not just 3+2 positioning, handles complex geometries on small parts
40-amp electrical requirement runs on standard shop power without upgrades

Limitations

100 lb platter load limit and 9.1-inch platter diameter restrict work to small parts under roughly 14.5-inch swing
8,100 RPM spindle limits high-speed finishing with small tools; medical shops may want the 15K or 20K RPM upgrade
15 HP spindle power is adequate for aluminum and mild steel but limits aggressive roughing in stainless and titanium
432 mm X-travel constrains multi-part fixturing; the UMC-500 adds 178 mm for roughly $36K more

Best For

Medical device manufacturers producing small implants, instruments, and components in titanium and stainless Dental labs and implant manufacturers running small-batch 5-axis parts Watch and jewelry manufacturers machining complex geometries in precious metals Prototype shops needing affordable 5-axis for small-part development and short runs Educational institutions and training programs introducing students to 5-axis machining Job shops adding 5-axis capability for the first time without a major capital commitment

Frequently Asked Questions

01 What does a new Haas UMC-400 cost?

Base price starts at around $156,995. With common options like through-spindle coolant, probing, and high-speed machining software, expect $175,000 to $200,000 for a production-ready configuration.

02 What is the difference between the UMC-400 and UMC-500?

The UMC-500 has 610 x 406 x 406 mm of travel versus 432 x 279 x 330 mm on the UMC-400. The UMC-500 also has a 30 HP spindle with 122 Nm of torque versus 15 HP and 62 Nm. The UMC-500 platter is 400 mm diameter with a 500 lb capacity versus 230 mm and 100 lb. Choose the UMC-400 for small parts; the UMC-500 for medium-sized work.

03 Can the UMC-400 do full simultaneous 5-axis?

Yes. The B and C axes support full simultaneous 5-axis contouring, not just 3+2 positioning. This handles complex geometries like impellers, turbine blades, and organic-shaped medical implants.

04 What is the maximum part size on the UMC-400?

Maximum part swing is 368 mm (14.5 in) diameter. The platter holds 45.4 kg (100 lb) maximum. The B-axis tilt range is +120 to -45 degrees. Parts must fit within these constraints when fixtured.

05 What spindle speed options are available?

The standard spindle is 8,100 RPM. Haas typically offers optional higher-speed spindles on UMC machines. Check with your local HFO for current 12,000 and 15,000 RPM options, which are worth the investment for aluminum and small-tool finishing.
