Machine Comparison
Okuma MU-4000V vs Okuma MU-5000V
Okuma vs Okuma · 5-Axis Machining Centers
Summary
The Okuma MU-4000V and the Okuma MU-5000V are Okuma 5-axis machining centers one table size apart. The MU-4000V has a 400 mm (15.75 in) table and the MU-5000V a 500 mm (19.69 in) table. Both rapid at 50 m/min (1,969 ipm), and both start with 32 tools, with 48, 64 or matrix magazines as options.
The remaining figures split two ways. The MU-5000V takes the larger part. The MU-4000V has the stronger listed spindle, 22/18.5 kW (30/25 hp) against 11/7.5 kW (15/10 hp), which is twice the power.
Specifications Comparison
| Specification | Okuma MU-4000V | Okuma MU-5000V |
|---|---|---|
| Table Size | 400 mm (15.75 in) | 500 mm (19.69 in) |
| Spindle Power | 22 /18.5 kW (30/25 hp) ▲ | 11/7.5 kW (15/10 hp) |
| Tool Capacity | 32-tool [48-tool, 64-tool: chain, over 64-tool: matrix] | 32 [48, 64, matrix] |
| Rapid Traverse | 50 m/min (1,969 ipm) | 50 m/min (1,969 ipm) |
Advantages
Okuma MU-4000V
- Twice the listed spindle power: 22/18.5 kW (30/25 hp) against 11/7.5 kW (15/10 hp)
- Suited to small 5-axis parts, high-speed aluminum work and small-tool finishing
Okuma MU-5000V
- 500 mm (19.69 in) table against 400 mm (15.75 in)
- Room for medium housings and brackets that do not fit the smaller table
Verdict
Choose by part size first. If the work is medium housings and brackets that need a 500 mm (19.69 in) table, the Okuma MU-5000V is the machine, at 11/7.5 kW (15/10 hp) listed spindle power. If parts fit a 400 mm (15.75 in) table, the Okuma MU-4000V gives 22/18.5 kW (30/25 hp) and suits high-speed aluminum work and small-tool finishing. Tool capacity and 50 m/min (1,969 ipm) rapids are the same on both, so they do not affect the choice.
