Machine Comparison
GROB G150 vs Grob G350
GROB vs Grob · 5-Axis Machining Centers
Summary
The GROB G150 and the Grob G350 are both 5-axis machining centers from the same maker, and the GROB G150 is the smaller of the two. The maker publishes few comparable figures for this pair, so the table holds three rows: X travel, spindle interface and rapid traverse.
The Grob G350 has the longer X axis, 600 mm against 450 mm (17.7 in), and faster rapids in X and Z at 70/45/90 m/min (X/Y/Z). The GROB G150 lists a single 60 m/min (2,362 ipm) figure, which is above the Grob G350's Y-axis rate. Both take HSK-A63 tooling, and the GROB G150 can also be ordered with HSK-E40, an extra-cost option for small tools.
Specifications Comparison
| Specification | GROB G150 | Grob G350 |
|---|---|---|
| X-Axis Travel | 450 mm (17.7 in) | 600 mm ▲ |
| Spindle Taper / Nose | HSK-A63 (HSK-E40 optional) | HSK-A63 |
| Rapid Traverse | 60 m/min (2,362 ipm) | 70/45/90 m/min (X/Y/Z) ▲ |
Advantages
GROB G150
- HSK-E40 spindle interface available as an option alongside the standard HSK-A63
- 60 m/min (2,362 ipm) rapid figure, above the Grob G350's 45 m/min Y-axis rate
- Sized for small 5-axis parts such as stainless steel medical components
Grob G350
- 600 mm of X travel against 450 mm (17.7 in)
- 70 m/min in X and 90 m/min in Z against 60 m/min
- Suits larger parts and pallet-changer production
Verdict
Choose by part size. The GROB G150 suits small 5-axis parts, such as stainless steel medical components, that fit within 450 mm (17.7 in) of X travel and may call for the optional HSK-E40 interface. The Grob G350 suits shops whose parts need 600 mm of X, or that want pallet-changer production and the quicker 70 m/min and 90 m/min rapids in X and Z. With only three rows to compare, confirm the remaining figures on each machine's own page.
