Advantages
Okuma MA-500HII
- Tool magazine options up to 400 against 194
- 500 × 500 mm pallet sized for medium production parts in steel and cast iron
Okuma MA-600HII
- 630 x 630 mm (24.8 x 24.8 in) pallet against 500 × 500 mm
- 60 tools standard against 40
- Higher-power spindle options above the shared 30 kW (40 hp) rating
Verdict
The Okuma MA-500HII suits steel and cast iron production on medium parts, such as engine blocks, valve bodies and pump housings, that fit a 500 × 500 mm pallet, with tool options up to 400. The Okuma MA-600HII suits larger die, mold, aerospace and heavy equipment parts that need a 630 x 630 mm pallet, more standard tools and the option of more spindle power. Size the machine to the fixture.
