Machine Comparison
EMAG VSC 250 vs Okuma GI-10NII
EMAG vs Okuma · CNC Grinding Machines
Summary
The EMAG VSC 250 and the Okuma GI-10NII share a category but not a job. The EMAG VSC 250 handles short chucked parts and, on DS/DDS machines, combines turning and bore grinding in one clamping. The Okuma GI-10NII is an internal grinder for bores in bushings, rings and gears.
The makers publish few comparable figures for this pair: the table has one row, rapid traverse. The EMAG VSC 250 is listed at 60 m/min (2,362 IPM) and the Okuma GI-10NII at 20 m/min (787 ipm). That figure bears on non-cutting time between parts, and it says nothing about accuracy, wheel spindles or part size.
Specifications Comparison
| Specification | EMAG VSC 250 | Okuma GI-10NII |
|---|---|---|
| Rapid Traverse | 60 m/min (2,362 IPM) ▲ | 20 m/min (787 ipm) |
Advantages
EMAG VSC 250
- Rapid traverse of 60 m/min (2,362 IPM) against 20 m/min (787 ipm)
- Turning and bore grinding in one clamping on DS/DDS machines
Okuma GI-10NII
- Dedicated internal grinder for bores in bushings, rings and gears
- Suited to short-cycle production grinding
Verdict
Choose by process. The Okuma GI-10NII is the choice for dedicated internal grinding of bores in production. The EMAG VSC 250 fits shops that want to turn and grind a short chucked part in one clamping, or that are assessing a used machine; its 60 m/min (2,362 IPM) rapids are the only figure here that can be set against the Okuma's 20 m/min (787 ipm). With one comparable row, the decision should rest on each machine's own page.
