Advantages
Okuma MILLAC 1000VH
- Twice the table load: 2,000 kg (4,400 lbs) against 1,000 kg (2,205 lbs)
- 1,000 × 1,000 mm (39.37 × 39.37 in) table against 800 × 800 mm (31.49 × 31.49 in)
Okuma MILLAC 800VH
- 30 m/min (1,181 ipm) rapid traverse against 24 / 24 / 12 m/min
- A smaller 800 × 800 mm table format for housings and castings that do not need the 2,000 kg rating
Verdict
Choose by workpiece weight and size. The Okuma MILLAC 1000VH is for castings and weldments that, with their fixture, exceed 1,000 kg (2,205 lbs) or need a 1,000 × 1,000 mm table; it accepts 2,000 kg (4,400 lbs). The Okuma MILLAC 800VH is for box-shaped housings that fit an 800 × 800 mm table, where its 30 m/min (1,181 ipm) rapids shorten positioning. Spindle power is the same 22/18.5 kW (30/25 hp), so the part decides.
