Machine Comparison
Citizen Miyano BNE-51MYY vs Citizen Miyano BNE-65ATC
Citizen Machinery vs Citizen Machinery · Mill-Turn Machines
Summary
The Citizen Miyano BNE-51MYY is a mill-turn machine for complex bar parts finished on both ends; the Citizen Miyano BNE-65ATC is listed as a turning center aimed at milled faces, angled holes and simultaneous 5-axis work. They serve different jobs, and Citizen publishes few comparable figures for this pair: the table has one row.
On that row the Citizen Miyano BNE-51MYY is the lighter machine at 8,080 kg against 9,200 kg. The BNE-65ATC is pitched at larger bar and chucked work and at jobs needing more milling tools than turret stations allow, while the BNE-51MYY is pitched at overlapped front and back machining of parts with many features.
Specifications Comparison
| Specification | Citizen Miyano BNE-51MYY | Citizen Miyano BNE-65ATC |
|---|---|---|
| Machine Weight | 8,080 kg | 9,200 kg |
Advantages
Citizen Miyano BNE-51MYY
- Lighter machine at 8,080 kg against 9,200 kg
- Overlapped front and back machining to shorten cycle times
- Aimed at parts with milled or cross-drilled features on both ends
Citizen Miyano BNE-65ATC
- Aimed at complex parts that need simultaneous 5-axis work
- Takes larger bar and chucked work, according to Citizen's positioning
- Tool changer for jobs that need more milling tools than turret stations allow
Verdict
These machines fit different jobs. The Citizen Miyano BNE-51MYY suits production of bar parts with features on both ends, where overlapping front and back work cuts cycle time. The Citizen Miyano BNE-65ATC suits larger, complex parts with angled holes and contoured faces that need simultaneous 5-axis milling and a deep tool supply in one setup. Weight is the only published figure to compare, so ask Citizen for travels and spindle data.
