Machine Comparison
DMG Mori CMX 50 U vs GROB G150
DMG Mori vs GROB · 5-Axis Machining Centers
Summary
The DMG Mori CMX 50 U and the GROB G150 are both compact 5-axis machining centers for small parts. The makers publish few comparable figures for this pair, so the table covers only X travel, spindle taper and rapid traverse.
The DMG Mori CMX 50 U has the longer X axis, 500 mm (19.7 in) against 450 mm (17.7 in), and takes CAT 40 / BBT 40 tooling. The GROB G150 moves twice as fast between cuts, with a rapid traverse of 60 m/min (2,362 ipm) against 30 m/min (1,181 ipm), and uses an HSK-A63 spindle, with HSK-E40 as an extra-cost option.
Specifications Comparison
| Specification | DMG Mori CMX 50 U | GROB G150 |
|---|---|---|
| X-Axis Travel | 500 mm (19.7 in) ▲ | 450 mm (17.7 in) |
| Spindle Taper / Nose | CAT 40 / BBT 40 | HSK-A63 (HSK-E40 optional) |
| Rapid Traverse | 30 m/min (1,181 ipm) | 60 m/min (2,362 ipm) ▲ |
Advantages
DMG Mori CMX 50 U
- 500 mm (19.7 in) of X travel against 450 mm (17.7 in)
- CAT 40 / BBT 40 spindle taper, for shops already holding 40-taper tooling
GROB G150
- Rapid traverse of 60 m/min (2,362 ipm) against 30 m/min (1,181 ipm)
- HSK-A63 spindle, with HSK-E40 available as an option for small tools
- Suits stainless steel components for medical technology, the application GROB lists
Verdict
On the figures both makers publish, the choice is between reach and speed. The DMG Mori CMX 50 U offers 500 mm (19.7 in) of X travel and CAT 40 / BBT 40 tooling, which suits five-sided work on prismatic parts in aluminum and light steel. The GROB G150 offers 60 m/min (2,362 ipm) rapids and HSK tooling, which suits small-tool work and stainless steel medical components where non-cutting time counts.
