Overview

The DMG Mori CMX 70 U is the larger sibling of the CMX 50 U, offering expanded travels and table capacity while maintaining the accessible pricing that defines the CMX U series. With 700 x 560 x 510 mm (27.6 x 22.0 x 20.1 in) of X/Y/Z travel and a 630 mm diameter rotary table rated for 300 kg (661 lb), the CMX 70 U handles larger workpieces than the CMX 50 U while remaining in the value segment of the 5-axis market.

The spindle runs at 12,000 RPM through a CAT 40 (BBT 40) taper, producing 22 kW (30 hp) and 86 Nm (63 ft-lb) of torque. A 15,000 RPM option is available. A-axis swivel range is -35 to +110 degrees with 360-degree continuous C-axis rotation. Rapid traverse hits 30 m/min (1,181 ipm).

The standard tool magazine holds 30 tools expandable to 60 or 120. Running on CELOS with Fanuc or Siemens control. The CMX 70 U sits between the entry-level CMX 50 U and the premium DMU monoBlock series in DMG Mori' 5-axis lineup.

Competitors include the Haas UMC-750, Hurco VMX60SRTi, and the lower end of Hermle C 32 U. New CMX 70 U machines price between $225,000 and $325,000. The larger travel and table capacity compared to the CMX 50 U makes it better suited for shops producing medium-sized aerospace fittings, medical implant housings, and mold components.

Strengths & Limitations

Strengths

Larger 700 x 560 x 510 mm travel and 630mm table expand part size capability over the CMX 50 U
300 kg table load handles medium-sized workpieces and multi-part fixtures that exceed smaller 5-axis platforms
Value pricing from $225,000 makes it one of the most accessible mid-range 5-axis machines from a Tier 1 OEM
CELOS with Fanuc or Siemens control choice matches shop standardization
Expandable to 120 tools for complex multi-operation 5-axis parts
DMG Mori global service network and parts availability provide support not available from smaller manufacturers

Limitations

30 m/min rapid traverse is significantly slower than premium 5-axis platforms
86 Nm spindle torque limits heavy roughing capability in steel and titanium
Linear guides rather than roller guideways limit rigidity under heavy cutting loads
30-tool standard magazine requires expansion for most production 5-axis work
No integrated automation options like pallet changers in the base configuration

Best For

Job shops producing medium-sized 5-axis components in aerospace, medical, and general manufacturing Mold and die shops machining electrodes and mold components requiring 5-axis access Prototype shops producing one-off and low-volume complex parts across diverse materials Medical device manufacturers running orthopedic and surgical instrument components Small aerospace subcontractors needing more travel than the CMX 50 U for larger fittings Shops stepping up from 3-axis to 5-axis that need larger work envelope than the CMX 50 U

Frequently Asked Questions

01 What does a CMX 70 U cost?

New CMX 70 U machines price between $225,000 and $325,000. With expanded ATC and options, expect toward the higher end. Used units from 2019-2023 trade between $120,000 and $200,000.

02 CMX 70 U vs CMX 50 U?

The CMX 70 U offers 40% more X-travel (700 vs 500 mm), larger 630mm table (vs 500mm), and 300 kg table load (vs 200 kg). The CMX 50 U is more compact and approximately $50,000-$75,000 less expensive.

03 CMX 70 U vs DMU 50?

The DMU 50 monoBlock offers higher rigidity from the one-piece casting, faster rapids, and better dynamic performance. The CMX 70 U offers more travel and a lower price point. Choose the DMU for premium accuracy; choose the CMX for value and work envelope.

04 Can it handle production volumes?

Yes, for medium-volume work. For high-volume production, consider adding automation or stepping up to the DMU series with faster rapids and more rigid platforms.

05 What spindle upgrades are available?

The 15,000 RPM option adds more surface speed for aluminum work. For heavy-duty steel or titanium, the CMX U series spindle torque may be limiting -- consider the DMU or CMX V series instead.
