Application Tips
Special application considerations exist
for Steadyline tooling. When directly replacing
a conventional bar with a passive/dynamic
Steadyline unit, it may be necessary to increase
cutting conditions to generate vibrations sufficient
to fully trigger the system’s damping response.
In addition, at long overhangs the bar may bend
but not vibrate and create a smaller diameter
than programmed. Breaking the operation up into
three lighter cuts should eliminate the bending
and produce the programmed diameter. It is
essential to note that the minimum machining
diameter must be large enough relative to the
bar diameter to allow for correct evacuation of
chips. Taking chip evacuation into account is
vital, especially in small and deep holes. The
use of coolant is recommended to aid with chip
evacuation and minimize heat transference to
the bar, which is temperature sensitive.
