MIYANO BNA - S2/DHY2

Fixed Headstock Type Automatic CNC Lathe

  • 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.” It offers high performance in compact space, round-the-clock stability and accuracy; and ease of use for fast set-ups and quick changeovers.

  • The 42S2 enables back machining with its 2 spindles and 1 turret, and combines a high level of basic performance with convenience of use. The S2 model delivers:

    • Increased versatility with the provision of a sub-spindle for pick-off and back machining.

    • Extensive tool range of an 8 station turret with half indexing in combination with multi tool holders.

    • Latest control technology for reduced non-cutting time and improved productivity.

  • The 42DHY2, with the combination of the Y-axis function incorporated in the main turret (HD1) and the compact 6-station sub-turret (HD2), can achieve further reductions in machining time through overlap processing and other forms of machining performed simultaneously on the main and sub spindles.

  • All BNA models incorporate the latest control technology for reduced non-cutting time and improved productivity.

  • Tooling is much easier for cutting workpieces of complicated shape since several tools can be mounted on the revolving tools and tool holders at one position of turret.
