Advantages
DMG Mori CMX 50 U
- More competitive pricing at $175,000 - $275,000 compared to $350,000 - $500,000
- Backed by DMG Mori's dealer and service network for parts and support
- Job shops adding their first 5-axis capability without committing to premium pricing
GF Mikron HPM 400U
- Higher maximum spindle speed of 20,000 RPM enables faster cutting on aluminum and non-ferrous materials
- More spindle power at 35 kW (47 hp) for aggressive material removal in harder materials
- Superior spindle torque at 120 Nm (88.5 ft-lb) vs 86 Nm (63 ft-lb)
- Faster rapid traverse at 45 m/min (1,772 ipm) reduces non-cutting time between operations
- Superior machine weight at 9,000 kg (19,842 lb) vs 6,600 kg (14,551 lb)
Verdict
The GF Mikron HPM 400U edges ahead on specifications in this comparison, particularly in Max Spindle Speed and Spindle Power. However, the DMG Mori CMX 50 U remains competitive and may be the better choice depending on price, dealer support in your area, or specific workholding and tooling considerations. Both are capable machines — the best decision comes from running your actual parts and evaluating total cost of ownership including tooling, training, and service.
