DMG Mori CMX 50 U vs SNK CMV
DMG Mori vs SNK · 5-Axis Machining Centers
Summary
The DMG Mori CMX 50 U and the SNK CMV are both 5-axis machining centers, but they serve different jobs. The CMX 50 U is a compact machine with 500 x 450 x 400 mm of travel and a 200 kg (440.9 lb) table; the SNK CMV is a large, configurable machine with 2,000 - 4,000 mm (78.7 - 157.5 in) of X travel, 1,500 - 2,500 mm of Y and a 10,000 kg (22,046 lb) table rating.
Both start at 12,000 RPM and both offer Fanuc 31i-B5 or Siemens 840D sl. The SNK has 30 kW (40 HP) against 22 kW (30 hp), an HSK-A63 taper with 20,000 / 30,000 RPM options, and 60 tools against 30 as standard. The CMX 50 U rapids faster, 30 m/min (1,181 ipm) against 24 m/min (945 IPM), and weighs 6,600 kg (14,551 lb) against 25,000 - 40,000 kg for the SNK.

Advantages
DMG Mori CMX 50 U
- 30 m/min (1,181 ipm) rapids against 24 m/min (945 IPM)
- Compact machine at 6,600 kg (14,551 lb) against 25,000 - 40,000 kg
- CAT 40 / BBT 40 taper for small-part work
SNK CMV
- 2,000 - 4,000 mm of X travel against 500 mm (19.7 in)
- 10,000 kg (22,046 lb) table load against 200 kg (440.9 lb)
- 30 kW (40 HP) spindle against 22 kW (30 hp)
- 60 tools standard (120 optional) against 30 (60 optional)
Verdict
The SNK CMV is for aerospace structural parts, medium-to-large mold cavities, heavy forgings and castings and defense components that need 2,000 mm or more of X travel and a 10,000 kg table. The CMX 50 U is for small fittings, medical parts, prototypes and training work within 500 x 450 x 400 mm. The two only meet on spindle speed and control choice.
