The BNA series packs sophisticated functions and high accuracy into a space-saving compact body.

The BNA series aims to set the new standard for machines for cutting bar stock, based on the concept of “space savings and sophisticated functions”.
The BNA-42DHY achieves further shortening of cycle times by adding a compact sub-turret to provide superimposition machining and other forms of simultaneous machining.
The BNA series offers high performance in compact space, round-the-clock stability and accuracy; and ease of use for fast set-ups and quick changeovers.
