SMART DAMPER OVERVIEW
UNIQUE DYNAMIC DAMPER ELIMINATES CHATTER Achieves high speed and high efficiency machining for work requiring a long projection length. SMART DAMPER
PATENT # 9027720
R
SPINDLE SYSTEM DUAL CONTACT
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.
