Machine Comparison
Chiron 08 Series Mill-Turn vs Okuma MULTUS B200II
Chiron vs Okuma · Mill-Turn Machines
Summary
The Chiron 08 Series Mill-Turn and the Okuma MULTUS B200II are both compact mill-turn machines for small, complex parts finished in one setup. They are built around different spindles: the Chiron uses a high-speed HSK-E32 / HSK-A40 spindle, while the Okuma has a lathe-style Ø140 flat [JIS A2-6] spindle nose for chucked work.
The published spindle speeds are not like-for-like, 30,000 - 54,000 rpm for the Chiron against 50~6,000 min⁻¹ for the Okuma, so they say more about each machine's focus than about which is faster. On the rows that compare directly, the Chiron carries 40 - 96 tools against 20 tools and rapids at 75 m/min on all three axes against 40/26 m/min (1,575/1,024 ipm) on the Okuma.

Advantages
Chiron 08 Series Mill-Turn
- 40 - 96 tools against 20 tools
- 75 m/min rapids on X, Y and Z against 40/26 m/min
- 30,000 - 54,000 rpm spindle for micro tools and fine milled features
Okuma MULTUS B200II
- Lathe-style Ø140 flat [JIS A2-6] spindle nose for chuck-sized turned parts
- B-axis head for off-center holes, flats and pockets on turned parts
- Aimed at shops with limited floor area taking on multitasking work for the first time
Verdict
Choose the Chiron 08 Series Mill-Turn for tiny, feature-dense medical, dental and watch parts where milling dominates, using its 30,000 - 54,000 rpm spindle, 40 - 96 tools and 75 m/min rapids. Choose the Okuma MULTUS B200II for chuck-sized turned parts that need secondary holes, flats and pockets, where turning is the main operation and a 20-tool store is enough.
