Machine Comparison
Okuma MILLAC 800VH vs Okuma MILLAC 853PF 5X
Okuma vs Okuma · 5-Axis Machining Centers
Summary
The Okuma MILLAC 800VH and the Okuma MILLAC 853PF 5X are both Okuma 5-axis machining centers, but with very different tables. The Okuma MILLAC 800VH has an 800 × 800 mm (31.49 × 31.49 in) table for box-shaped parts; the Okuma MILLAC 853PF 5X has a 3,200 × 850 mm (125.99 × 33.47 in) table for long work.
The Okuma MILLAC 853PF 5X is also stronger at the spindle: 45/55 kW (60/75 hp) against 22/18.5 kW (30/25 hp), and a 60–12,000 rpm speed range against 100–10,000 rpm. Rapid traverse is listed at 30 m/min (1,181 ipm) for both, with a third-axis figure of 24 m/min on the Okuma MILLAC 853PF 5X.

Advantages
Okuma MILLAC 800VH
- Square 800 × 800 mm (31.49 × 31.49 in) table suited to five-sided machining of housings and castings
- A smaller format for shops whose parts do not need a 3,200 mm long table
Okuma MILLAC 853PF 5X
- 3,200 × 850 mm (125.99 × 33.47 in) table against 800 × 800 mm (31.49 × 31.49 in)
- 45/55 kW (60/75 hp) spindle power against 22/18.5 kW (30/25 hp)
- 12,000 rpm top spindle speed against 10,000 rpm
Verdict
The table shape settles this. Choose the Okuma MILLAC 853PF 5X for long structural parts, or rows of smaller parts fixtured along its 3,200 × 850 mm table, and for high-removal-rate milling with 45/55 kW (60/75 hp) at the spindle. Choose the Okuma MILLAC 800VH for box-shaped housings and castings that sit on an 800 × 800 mm table and need five-sided access rather than length. Rapid traverse is listed at 30 m/min for both and does not decide it.
