Overview

The DMG Mori DMC 55 H twin is a twin-pallet horizontal machining center with integrated 5-axis capability, combining the productivity of a pallet-change HMC with the flexibility of simultaneous 5-axis machining. This dual-concept design lets shops run complex multi-sided parts with full 5-axis access while maintaining the load-while-cutting workflow that drives spindle utilization in horizontal machining.

Travel sits at 550 x 550 x 520 mm (21.7 x 21.7 x 20.5 in) with B-axis swivel of -10 to +110 degrees and 360-degree continuous C-axis rotation. The speedMASTER spindle runs at 14,000 RPM through an HSK-A63 taper, producing 25 kW (34 hp) and 87 Nm (64 ft-lb) of torque. Rapid traverse hits 60 m/min (2,362 ipm) on all linear axes.

The twin-pallet changer with 500 x 400 mm (19.7 x 15.7 in) pallets enables loading one part while the other cuts. Tool storage holds 40 tools standard expandable to 120. Maximum pallet load is 300 kg (661 lb). Running on CELOS with Fanuc or Siemens control.

Competitors include the Makino DA300 and Mazak HCR-5000S in the horizontal 5-axis segment. New DMC 55 H twin machines price between $350,000 and $475,000. The machine targets shops producing complex aerospace and medical components that need both 5-axis capability and the productivity of pallet-change horizontal machining.

Strengths & Limitations

Strengths

Twin-pallet changer combines 5-axis flexibility with load-while-cutting HMC productivity
Horizontal spindle provides gravity-assisted chip evacuation for deep-cavity 5-axis work
14,000 RPM HSK-A63 spindle delivers precision cutting capability for aerospace and medical parts
60 m/min rapids keep non-cutting time low during complex 5-axis repositioning moves
Available with Fanuc or Siemens control to match shop standardization
Compact footprint for a pallet-change 5-axis horizontal machine

Limitations

300 kg pallet load limits workpiece size and fixture weight compared to dedicated HMCs
87 Nm spindle torque is modest for heavy roughing in steel and cast iron
550 x 550 x 520 mm travel envelope limits part size compared to standard 500mm HMCs
Niche machine category with fewer direct competitors makes benchmarking and resale more challenging

Best For

Aerospace component manufacturers needing 5-axis access with pallet-change productivity on complex housings Medical device production requiring multi-sided machining with horizontal chip evacuation Job shops producing complex prismatic parts that benefit from both 5-axis capability and pallet automation Mold and die component production where horizontal chip flow and 5-axis access are both needed Production cells requiring automated part cycling with full 5-axis machining capability

Frequently Asked Questions

01 What does a DMC 55 H twin cost?

New machines price $350,000-$475,000 depending on configuration. The twin-pallet system is included in the base price.

02 DMC 55 H twin vs Makino DA300?

Both target the horizontal 5-axis niche. The Makino DA300 is known for tighter accuracy and higher rigidity. The DMC 55 H twin offers more flexibility with Fanuc or Siemens control options and wider B-axis range.

03 Is this a true 5-axis simultaneous machine?

Yes, the DMC 55 H twin supports full 5-axis simultaneous machining with B and C rotary axes combined with X, Y, Z linear axes.

04 What makes it different from a standard NHX?

The DMC 55 H twin adds full 5-axis capability (B/C rotary axes) to a horizontal platform with twin pallets. Standard NHX machines are 4-axis horizontal (B-axis only) with typically larger work envelopes.
