The BNA42DHY CNC Fixed Head delivers high performance and accuracy in a space-saving, compact design.
It belongs to the BNA series machines, built on the concept of sophisticated functionality and minimal footprint.
This model includes two spindles, a main turret, and a compact sub-turret for superimposition machining. Superimposed cutting and simultaneous operations help shorten cycle times and boost productivity.
The BNA42DHY CNC Fixed Head excels in Bar Stock Machining with round-the-clock precision and process stability.
Its compact form fits easily into space-constrained shops without sacrificing capability. Fast setups and quick changeovers make it ideal for medium to high batch production environments.
Miyano’s proven control system and mechanical stability ensure consistent part quality with every cycle.
