Comparison of Oscillatory Waveforms
The Smart Damper incorporates a damping
mechanism and reduces chatter instantly. The
Smart Damper solves various problems caused
by chatter due to long projection, such as poor
surface roughness, unacceptable cutting time,
and shortened tool life.

SYSTEM
An incorporated unique damper that
functions as both a counter damper
and friction damper.
Patented counter weight maximizes
effect of the friction damper. Chatter
is absorbed effectively and higher
machining accuracy is achieved.
