MIYANO BNA - 42GTY

Designed for accuracy and long tool life

  • 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.

  • The turret has 8 stations, but the half-indexing mechanism makes it possible to mount tools at up to 16 positions. The use of optional multiple tool holders can further increase the number of tool positions.
