DMG Mori CMX 50 U vs GF Mikron HPM 400U
DMG Mori vs GF Machining Solutions · 5-Axis Machining Centers
Summary
The DMG Mori CMX 50 U and the GF Mikron HPM 400U are compact 5-axis machining centers with identical 500 x 450 x 400 mm travels and a 30-tool magazine that can be expanded to 60. The difference is in the spindle and axis drives, where the HPM 400U is specified for heavier and faster cutting.
The GF Mikron spindle reaches 20,000 RPM against 12,000 RPM, with 35 kW (47 hp) against 22 kW (30 hp) and 120 Nm (88.5 ft-lb) against 86 Nm (63 ft-lb), on an HSK-A63 taper rather than CAT 40 / BBT 40. It rapids at 45 m/min (1,772 ipm) against 30 m/min (1,181 ipm) and runs a Heidenhain TNC 7. The CMX 50 U is the lighter machine at 6,600 kg (14,551 lb) against 9,000 kg (19,842 lb) and offers Fanuc or Siemens under CELOS.

Advantages
DMG Mori CMX 50 U
- Choice of Fanuc 31i-B5 or Siemens 840D sl control under CELOS
- CAT 40 / BBT 40 taper rather than HSK-A63
- Lighter machine at 6,600 kg (14,551 lb) against 9,000 kg (19,842 lb)
GF Mikron HPM 400U
- 20,000 RPM spindle against 12,000 RPM
- 35 kW (47 hp) and 120 Nm (88.5 ft-lb) against 22 kW (30 hp) and 86 Nm (63 ft-lb)
- 45 m/min (1,772 ipm) rapids against 30 m/min (1,181 ipm)
Verdict
For titanium, hardened mold steel, impellers and other demanding aerospace and medical work, the GF Mikron HPM 400U is the stronger choice, with 20,000 RPM, 35 kW and 120 Nm in the same envelope. The CMX 50 U fits shops adding a first 5-axis machine for prototypes, training and low-volume fittings, where 12,000 RPM is enough and a Fanuc or Siemens control matches the rest of the floor.
