Machine Comparison
DMG Mori DMC 55 H twin vs Makino a120nx
DMG Mori vs Makino · Horizontal Machining Centers
Summary
The DMG Mori DMC 55 H twin and the Makino a120nx are both horizontal machining centers, but they serve different jobs. The DMG Mori DMC 55 H twin is a two-spindle production machine with 580 x 750 x 500 mm of X/Y/Z travel and a 400 kg (881.8 lb) load. The Makino a120nx is a large-part HMC with 1,900 x 1,600 x 1,700 mm of travel and a 3,000 kg load, 5,000 kg optional.
The Makino leads on every size row. The DMG Mori leads on tool capacity, listing a wheel magazine of up to 214 tools per spindle against 204 on the Makino. The tool change figures are not comparable: DMG Mori quotes up to 2.9 s chip-to-chip, while Makino quotes 2.2 sec tool-to-tool for 12kg tools.

Advantages
DMG Mori DMC 55 H twin
- Machines identical parts two at a time, one per spindle
- Up to 214 tools per spindle against 204
Makino a120nx
- 1,900 x 1,600 x 1,700 mm of X/Y/Z travel against 580 x 750 x 500 mm
- 3,000 kg standard load (5,000 kg optional) against 400 kg (881.8 lb)
- Aimed at heavy roughing of large steel and iron castings
Verdict
Choose by part size. The DMG Mori DMC 55 H twin fits series production of small to mid-size parts within 400 kg (881.8 lb), where machining two identical parts at once and a deep tool supply shorten the cycle. The Makino a120nx fits large castings and fabrications up to 3,000 kg, or 5,000 kg with the option, that need 1,900 mm of X travel. A shop weighing one is rarely weighing the other.
