Overview

The DMG Mori CMX 90 U is a compact 5-axis machining center occupying the gap between the smaller CMX 70 U and the larger CMX 110 U in DMG Mori's entry-to-mid-range 5-axis lineup. With 900 x 700 x 580 mm (35.4 x 27.6 x 22.8 in) of X/Y/Z travel and a 750 mm diameter swivel rotary table rated for 400 kg (882 lb), the CMX 90 U offers a meaningfully larger work envelope than the CMX 70 U while maintaining the accessible pricing and compact footprint that defines the CMX U family.

The swivel rotary table provides A-axis movement from -35 to +110 degrees with 360-degree continuous C-axis rotation, enabling full simultaneous 5-axis machining in a machine that fits a standard production floor allocation. Maximum workpiece dimensions are 800 mm (31.5 in) in diameter and 500 mm (19.7 in) in height, covering most aerospace fittings, medical housings, mold components, and energy parts that are too large for 500-630mm table machines.

The inline spindle delivers 22 kW (30 hp) and 120 Nm (88 ft-lb) of torque at 12,000 RPM standard through a CAT 40 (BBT 40) taper. A 15,000 RPM option is available for aluminum-intensive production. Rapid traverse is 30 m/min (1,181 ipm) on linear guides, consistent with the CMX U family's value positioning relative to the premium DMU monoBlock series.

The standard tool magazine holds 30 tools expandable to 60 or 120. CELOS X runs on top of Fanuc 31i-B5 or Siemens 840D sl control. The machine can be optionally configured with PH 150 or PH 300 pallet handling automation from DMG Mori.

New CMX 90 U machines price between $240,000 and $360,000, making this one of the most competitively priced 5-axis machines with 900mm X-travel from a Tier 1 manufacturer. Primary competitors include the Haas UMC-750, Hurco VMX60SRTi, and the lower end of the Brother Speedio W1000Xd1 5-axis range. For shops needing a step up from 700mm travel 5-axis machines without committing to premium DMU pricing, the CMX 90 U provides the right balance of work envelope, performance, and investment.

Strengths & Limitations

Strengths

900mm X-travel provides a larger work envelope than the CMX 70 U (700mm) while remaining in accessible CMX U price territory
750mm swivel table with 400 kg capacity handles larger aerospace fittings, medical housings, and mold components than smaller 5-axis platforms
Full simultaneous 5-axis capability with A/C swivel rotary table — not limited to 3+2 positioning
CELOS X with Fanuc or Siemens control choice matches existing shop standardization without committing to a proprietary control
Compact footprint for a 900mm travel machine fits standard production floor allocations and minimizes facility investment
DMG Mori global service network and parts availability provide support not available from smaller 5-axis manufacturers
Expandable to 120 tools and optional PH 150/300 pallet handling for automation capability

Limitations

30 m/min rapid traverse is significantly slower than premium 5-axis machines (42-60 m/min) — productivity gap on high-volume work
120 Nm spindle torque limits aggressive roughing in steel and titanium; the CMX U series is optimized for lighter cutting passes
30-tool standard magazine requires immediate expansion for complex multi-operation 5-axis programs
Linear guides rather than roller guideways limit structural rigidity at aggressive cutting depths
No integrated pallet changer in base configuration — automation requires add-on PH units at additional cost

Best For

Job shops machining medium-sized 5-axis components in aerospace, medical, and precision engineering Mold and die shops producing mold components, inserts, and electrodes requiring 5-axis access Prototype and low-to-medium volume production shops needing more work envelope than the CMX 70 U Aerospace subcontractors producing fittings, brackets, and structural components from aluminum and titanium Medical device manufacturers machining implant housings, surgical instrument handles, and device casings Shops stepping up from 3-axis to 5-axis that need 900mm+ X-travel at entry-5-axis pricing

Frequently Asked Questions

01 What does a new DMG Mori CMX 90 U cost?

New CMX 90 U machines price between $240,000 and $360,000. Base configuration with 30-tool magazine and 12,000 RPM spindle starts near $240,000. Adding the 15,000 RPM spindle, 60 or 120-tool ATC, high-pressure coolant, probing, and PH automation pushes toward $360,000. Used CMX 90 U units trade from $110,000 to $200,000 depending on year and configuration.

02 CMX 90 U vs CMX 70 U — what do I gain?

The CMX 90 U adds 200mm of X-travel (900 vs 700mm), a larger 750mm table (vs 630mm), and higher 400 kg table load (vs 300 kg). This enables larger workpieces and heavier fixtures. The CMX 70 U is approximately $30,000-$50,000 less expensive. Step up to the CMX 90 U when your parts or tombstones exceed the CMX 70 U capacity.

03 CMX 90 U vs Haas UMC-750?

Both target the mid-range 5-axis market at similar price points. The Haas UMC-750 offers a larger standard tool capacity and is typically less expensive. The CMX 90 U provides Fanuc or Siemens control options and the CELOS X interface, which is preferred by shops standardized on those controls. Surface finish capability is generally comparable; the DMG Mori has a slight edge on fit and finish.

04 Is the CMX 90 U a true simultaneous 5-axis machine?

Yes. The CMX 90 U supports full simultaneous 5-axis machining with A/C swivel rotary table. It is not limited to 3+2 positioning. Programs with simultaneous 5-axis toolpaths for complex curved surfaces, undercuts, and compound angles run natively.

05 What automation options are available?

The CMX 90 U is compatible with DMG Mori's PH 150 (150 kg capacity) and PH 300 (300 kg capacity) pallet handling systems for automated part loading. Robot integration via standardized interface ports is also supported. For high-volume automation, the larger DMU series with full pallet pool systems offers more comprehensive options.
