Machine Information

Miyano BNA-42MSY2

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

Miyano BNA-42MSY2

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.
