DMG Mori CMX 50 U vs Mitsui Seiki Vertex 100
DMG Mori vs Mitsui Seiki · 5-Axis Machining Centers
Summary
The DMG Mori CMX 50 U and the Mitsui Seiki Vertex 100 are both 5-axis machining centers, but they serve different jobs. The Vertex 100 is a larger precision machine with 1,000 x 700 x 500 mm of travel against 500 x 450 x 400 mm and a 500 kg (1,102 lb) table against 200 kg (440.9 lb), aimed at turbine, impeller and aerospace parts.
It also leads on the spindle and axes: 20,000 rpm against 12,000 RPM, 30 kW (40 HP) continuous against 22 kW (30 hp), 60 tools against 30, and 50 m/min (1,969 ipm) rapids against 30 m/min (1,181 ipm). The CMX 50 U is the smaller machine at 6,600 kg (14,551 lb) against 16,000 kg (35,274 lb), with a CAT 40 / BBT 40 taper and a choice of Fanuc or Siemens.

Advantages
DMG Mori CMX 50 U
- Smaller machine at 6,600 kg (14,551 lb) against 16,000 kg (35,274 lb)
- CAT 40 / BBT 40 taper rather than HSK-A63
- Siemens 840D sl available as well as Fanuc 31i-B5
Mitsui Seiki Vertex 100
- 1,000 x 700 x 500 mm of travel against 500 x 450 x 400 mm
- 500 kg (1,102 lb) table load against 200 kg (440.9 lb)
- 20,000 rpm and 30 kW (40 HP) against 12,000 RPM and 22 kW (30 hp)
- 60 tools (90 optional) and 50 m/min (1,969 ipm) rapids against 30 tools and 30 m/min
Verdict
The Mitsui Seiki Vertex 100 is for turbine blades, impellers, blisks, implants and defense parts where first-article accuracy and 1,000 mm of X travel matter. The CMX 50 U is for job shops, prototype work, training and small fittings within 500 x 450 x 400 mm, where a smaller machine with CAT 40 tooling is enough.
