KAISER BORING SYSTEM
FINE BORING HEADS (INSERT HOLDER TYPE) Quick Micron-Level Adjustment
EWN BORING HEAD Prebalanced Design/Multifunction Head Range: ø.787"-8.000" • Prebalanced design supports high-speed boring •Abundance of insert holders
EWN BORING HEAD SMART DAMPER (PAT. 9027720) Built-In Damper Range: ø.787"-8.000"
Back Boring Available as Standard Supports back boring by simply reversing the insert holder.
•Integrated EWN BORING HEAD and SMART DAMPER •Closely adjacent vibrating point and damper achieve a high damping effect
Emphasis on Chip Evacuation Properties Replacing the insert holder makes it possible to secure sufficient clearance for chips.
Chatter Suppressing Mechanism Patented counterweight maximizes effect of the friction damper. Chatter is absorbed effectively and higher machining accuracy is achieved.
