BNA-42GTY

Miyano BNA-42GTY

The BNA-42GTY is configured with two spindles, one turret, two Y axes, gang tools and X3 axis to back spindle, the BNA-42GTY can mount up to 45 tools.

Featuring:

  • 3 tool simultaneous cutting
  • Renowned Miyano accuracy
  • High productivity with fast cycle times
  • Versatile tool layout

Superimposition control allows simultaneous cutting with two tools at the main spindle (SP1), or with three tools when the sub spindle (SP2) is included, shortening cycle times.
