Machine Comparison
Okuma MB-46V II vs Okuma MB-46VAE
Okuma vs Okuma · Vertical Machining Centers
Summary
The Okuma MB-46V II and the Okuma MB-46VAE are small Okuma vertical machining centers with the same work envelope: 560 mm (22.0 in) of X travel, 460 mm (18.1 in) in Y and Z, and a 760 x 460 mm table. Both start with a 20-tool magazine.
The differences are in rapid traverse and magazine options. The MB-46V II moves at 42 m/min in X-Y and 36 m/min in Z, against 32 m/min in X/Y and 24 m/min in Z on the MB-46VAE. The MB-46VAE lists more optional magazines: 32, 48 or 98 tools, against 32 or 48 on the MB-46V II.
Specifications Comparison
| Specification | Okuma MB-46V II | Okuma MB-46VAE |
|---|---|---|
| X-Axis Travel | 560 mm (22.0 in) | 560 mm (22.0 in) |
| Y-Axis Travel | 460 mm (18.1 in) | 460 mm (18.1 in) |
| Z-Axis Travel | 460 mm (18.1 in) | 460 mm (18.1 in) |
| Table Size | 460 × 760 mm (18.11 × 29.92 in) | 760 x 460 mm (29.9 x 18.1 in) |
| Tool Capacity | 20 [32, 48] | 20 (standard); 32, 48, or 98 optional |
| Rapid Traverse | 42/36 m/min (X-Y: 1,654 Z: 1,417 ipm) ▲ | 32 m/min (X/Y); 24 m/min (Z) |
Advantages
Okuma MB-46V II
- Rapid traverse of 42 m/min in X-Y and 36 m/min in Z against 32 m/min and 24 m/min
- Less non-cutting time on short-cycle work with many positioning moves
Okuma MB-46VAE
- Optional 98-tool magazine; the largest option listed for the Okuma MB-46V II is 48 tools
- Suited to small precision parts and fine finishing that need many tools loaded at once
Verdict
The work envelope is identical, so choose on speed and tool count. The Okuma MB-46V II is the better fit for short-cycle production, where 42 m/min X-Y rapids against 32 m/min shorten every positioning move. The Okuma MB-46VAE is the one to pick when a job family needs many tools loaded at once, because only it lists a 98-tool optional magazine. For small prismatic parts that need neither, both cover the same 560 mm (22.0 in) of X travel.
