Configured with two spindles and one turret and equipped with a Y axis and X2 axis, the BNA-42MSY2 is able to handle complex machining with short cycle times and fast set ups.

The X2 axis to sub-spindle enables simultaneous independent machining of the front and back of the workpiece. This, in effect, provides the benefits of a twin turret machine with the significant cost savings of a single turret model.


  • 2 tool simultaneous cutting
  • Renowned Miyano accuracy
  • Quick to set up and changeover
  • Highly efficient for small and medium batch sizes (lots)
  • Compact design for improved floor space efficiency

Tooling Area

High-rigidity spindle


To achieve powerful cutting, the spindle, which is the key component in machining, is equipped with angular contact ball bearings at the front and double-row cylindrical roller bearings at the rear.

Cycle time shortened by superimposition control


A turret incorporating X, Y and Z axes (HD1) and a sub spindle incorporating X and Z axes (SP2) open up the possibility of machining by superimposition control, where the sub spindle synchronizes with the turret to machine a workpiece in the main spindle (SP1), a very effective way to shorten cycle time.
