Machine Information

Miyano BNE-51MSY

The BNE series is renowned for its high rigidity, heavy cutting capability and outstanding precision. The BNE-51MSY model extends the ability of the BNE series with the adoption of X3 axis on the back spindle (SP2) and synchronized/ superimposed control for 3-tool simultaneous machining.


Faster cycle times
Outstanding ease-of-use
Ability to machine complex work pieces




In addition, superimposition control allows simultaneous cutting with two tools by synchronizing the cutting at SP2 with the cutting at SP1, and also simultaneous cutting with three tools including SP2, helping to shorten cycle times. Equipping SP2 with an X3-axis has enabled simultaneous hole machining on both end face.
