Overview

The DMG Mori ecoMill 70 is the larger sibling in the ecoMill economy VMC series, offering 700 x 500 x 450 mm (27.6 x 19.7 x 17.7 in) of travel in a machine designed to compete on value without abandoning the build standards that the DMG Mori name represents. It targets shops that need a capable, reliable vertical machining center for everyday production work at a price closer to Korean and Taiwanese VMCs than to the premium NVX or CMX lines.

Powering the machine is a 15,000 RPM spindle producing 11 kW (14.8 hp) and 70 Nm of torque through an SK40 taper. That's the same spindle package as the ecoMill 50, but the larger table (800 x 500 mm / 31.5 x 19.7 in) with 500 kg (1,102 lb) load capacity allows the ecoMill 70 to tackle bigger castings, weldments, and fixture plates. Rapid traverse is 36 m/min across all axes, keeping idle time low on medium-run batches.

Control options mirror the rest of the ecoMill lineup: Siemens Sinumerik 828D or Fanuc 0i-MF. Both are battle-tested in job shop environments, have broad post-processor support from CAM vendors, and offer a large pool of trained operators. The standard ATC holds 24 tools, with a 30-tool drum available for shops running more complex programs. Optional through-spindle coolant and chip conveyor adapt the machine for higher-volume production environments.

The ecoMill 70 fills the gap for shops whose parts are slightly too large for the 500mm class but who cannot justify the step up to the CMX 800 V or NVX 7000. It is particularly common in automotive supplier environments machining transmission cases, pump housings, and structural brackets, where the combination of table size, reliability, and acquisition cost drives the purchasing decision.

Strengths & Limitations

Strengths

700mm X-axis and 800 x 500 mm table cover most mid-size production components that a 500mm VMC cannot accommodate
500 kg table load handles castings, weldments, and heavy fixture plates without strain
DMG Mori build quality and global service network at an economy price point competitive with Asian VMCs
Siemens 828D and Fanuc 0i-MF control options suit virtually any operator background

Limitations

11 kW / 70 Nm spindle is on the light side for sustained heavy steel or cast iron work at full depths
8-micron positioning accuracy is adequate for general production but not for tight-tolerance precision work
Through-spindle coolant and chip conveyor are options, not standard — add to the base price for production applications

Best For

Automotive suppliers machining transmission housings, pump bodies, and structural brackets in aluminum and cast iron Job shops running medium-volume batches of parts in the 500-700 mm range that exceed a 500mm VMC's capacity Shops prioritizing DMG Mori service availability and long-term resale value over cutting-edge performance specs Production cells with a mix of part sizes where a single 700mm machine can handle more of the part family than a 500mm unit

Frequently Asked Questions

01 What is the difference between the ecoMill 50 and ecoMill 70?

The ecoMill 70 has 200mm more X-axis travel (700mm vs 500mm), a larger table (800 x 500mm vs 600 x 400mm), and a higher table load capacity (500 kg vs 400 kg). The spindle package — 11 kW, 70 Nm, 15,000 RPM SK40 — is identical. Choose the ecoMill 70 when your typical parts exceed 500mm in the longest dimension or when fixture plate weight pushes past 400 kg.

02 Can the ecoMill 70 handle production runs of aluminum automotive parts?

Yes, this is a natural fit. The 15,000 RPM spindle, 36 m/min rapids, and large table combine well for high-speed aluminum machining of housings, brackets, and panels. Adding through-spindle coolant and a chip conveyor makes it suitable for sustained production with minimal operator intervention between cycles.

03 Is the ecoMill 70 suitable for stainless steel and hardened steel?

The ecoMill 70 will cut stainless and 4140 at moderate parameters, but the 11 kW spindle limits aggressive material removal rates in harder materials. For regular heavy steel or hard milling work, the NVX 7000 with its higher-power spindle and DCG structure is the more appropriate choice.

04 What chip management options are available?

A chip conveyor and coolant management system are available as options. For production environments generating significant chip loads, specifying the chip conveyor at order is strongly recommended. The ecoMill 70's enclosure and coolant tank are sized for standard machining center use.

05 How does the ecoMill 70 compare to mid-range Asian VMCs at the same price?

The ecoMill 70 typically costs 10-20% more than comparable Taiwanese or Korean VMCs (Leadwell, Doosan, Hyundai WIA). The premium buys DMG Mori's global service network, better resale value, and the assurance of DMG Mori-quality assembly. Shops that have been burned by service response times on off-brand machines often justify the price difference on total cost of ownership.
