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.

Tooling Area
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.
