Advantages
DMG Mori DMU 65 H monoBlock
- Greater x travel of 735 mm (28.9 in) accommodates larger workpieces
- Superior tool change time at 3.0 sec tool-to-tool vs 1.4 sec chip-to-chip
- Backed by DMG Mori's dealer and service network for parts and support
- Mold and die shops machining deep-cavity components where horizontal chip flow prevents chip packing
DMG Mori i 50
- Greater z travel of 800 mm (31.5 in) accommodates larger workpieces
- Higher maximum spindle speed of 15,000 RPM enables faster cutting on aluminum and non-ferrous materials
- More spindle power at 26 kW (35 hp) for aggressive material removal in harder materials
- Superior spindle torque at 169 Nm (125 ft-lb) vs 157 Nm (116 ft-lb)
- Larger tool magazine with 60 tools standard (90, 120 optional) capacity reduces manual tool changes on complex parts
Verdict
The DMG Mori i 50 edges ahead on specifications in this comparison, particularly in Z Travel and Max Spindle Speed. However, the DMG Mori DMU 65 H monoBlock 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.
