Machine Comparison
Citizen Miyano BNE-51MSY vs Citizen Miyano BNE-51MYY
Citizen Machinery vs Citizen Machinery · Mill-Turn Machines
Summary
The Citizen Miyano BNE-51MSY and the Citizen Miyano BNE-51MYY are sister mill-turn machines from Citizen Miyano's BNE-51 family, both built to finish bar parts complete on both ends. Citizen publishes few comparable figures for this pair: the table has one row, and on it the two are close, at 8,000 kg for the MSY against 8,080 kg for the MYY.
The difference is in how Citizen positions them. The Citizen Miyano BNE-51MSY splits tools across two turrets, with a Y-axis turret for off-center holes and flats on short bar parts. The Citizen Miyano BNE-51MYY targets parts with milled or cross-drilled features on both ends, overlapped front and back machining, and longer parts that need many driven tools.
Specifications Comparison
| Specification | Citizen Miyano BNE-51MSY | Citizen Miyano BNE-51MYY |
|---|---|---|
| Machine Weight | 8,000 kg | 8,080 kg |
Advantages
Citizen Miyano BNE-51MSY
- Slightly lighter at 8,000 kg against 8,080 kg
- Aimed at short bar parts with tools split across two turrets
Citizen Miyano BNE-51MYY
- Aimed at parts with milled or cross-drilled features on both ends
- Overlapped front and back machining to shorten cycle times
- Positioned for longer parts that need many driven tools
Verdict
Weight will not decide this pair. Pick the Citizen Miyano BNE-51MSY for short bar parts where two turrets share the tooling and Y-axis work is limited to off-center holes and flats. Pick the Citizen Miyano BNE-51MYY for complex parts with milled or cross-drilled features on both ends, where many driven tools and overlapped front and back machining shorten the cycle. Ask Citizen for travel and spindle figures, which the table does not list.
