Tooling Area
BNA-42GTY IN DETAIL
Superimposition Control: Allows simultaneous cutting with two tools at SP1, or three tools when SP2 is included, drastically shortening cycle times.
Half-Indexing Mechanism: The 8-station turret can mount tools at up to 16 positions. Optional multiple tool holders can further increase this capacity.
