Advantages
DMG Mori CMX 50 U
- Greater x travel of 500 mm (19.7 in) accommodates larger workpieces
- Greater y travel of 450 mm (17.7 in) accommodates larger workpieces
- Greater z travel of 400 mm (15.7 in) accommodates larger workpieces
- More spindle power at 22 kW (30 hp) for aggressive material removal in harder materials
- Superior max workpiece diameter at 500 mm (19.7 in) vs 200 mm (7.9 in)
Kern Evo
- Larger tool magazine with Up to 90 tools capacity reduces manual tool changes on complex parts
- Backed by Kern Microtechnik's dealer and service network for parts and support
- Medical and dental device manufacturers producing small implants, prosthetics, and surgical tools to tight tolerances
Verdict
The DMG Mori CMX 50 U holds a spec advantage in this comparison, but the right choice depends on your shop's priorities. If the DMG Mori CMX 50 U's strengths in areas like X Travel and Y Travel align with your work, it's the clear pick. The Kern Evo may still win on dealer proximity, existing tooling compatibility, or specific features that matter most to your applications. Request quotes from both dealers and, if possible, run your actual parts on each machine before deciding.
