BNA42SY
Fixed Headstock Type CNC Automatic Lathe

Miyano BNA42SY

SY type with improved performance as a bar-material processing machine

The SY type has a dual-spindle/single turret tool post mechanical configuration, and the base and turret rigidity has been increased to improve basic functions.

  • A surface plate structure, a tradition of the Miyano brand, has been carried over for the bed, an essential element for machining, while both size and weight have been increased in order to improve damping performance.
  • The turret tool post has been equipped with a Y axis to expand the number of installed tools to 12 stations in order to provide the use of a rich assortment of tools, as well as simultaneous left/right machining for superimposed machining and similar processes.
  • The tool holder and rotary tools are the same used for the current BNA Series and the program compatibility is also ensured.
