Machine Information
Miyano BNA-42MSY2
The BNA-42SY has a dual-spindle/ single turret tool post-mechanical configuration, and the base and turret rigidity has been increased to improve basic functions. 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
Featuring
Dual-spindle/single turret tool post
Tool post equipped with Y-axis enables the use of 12 stations
Increased base and turret rigidity
Left/Right simultaneous machining
Power is increased up to 11 kW during Spindle acceleration and deceleration
LFV Capable (Low-Frequency Vibration)
Miyano BNA-42SY5
Tooling Area
The opening has been enlarged for easier access and provided with a large window to improve visibility. The port through which chips fall has been enlarged and the removal port has been moved closer to the outer edge of the cover to make it easier to clean away chips. These new NC units are standard-equipped with a dual-check safety function to improve safety and productivity.
Tool post has been equipped with a Y axis to expand the number of installed tools to 12 stations
Simultaneous machining using both left and right-side spindles enables the turret tool post and front spindle to perform machining while the back spindle follows after to perform superimposed and similar types of machining, thereby further reducing the processing time.
