Big Kaiser Precision Tooling has released two smaller sizes of the EWN Smart Damper precision boring heads, which eliminate vibration in deep-hole finish boring with a patented damping system. The additions make it the first time the EWN Smart Damper has been available in diameters below 1.260", down to 0.787". The CK1 head has a length of 3.937" and the CK2 4.921".

Big Kaiser’s modular CK/CKB system allows for versatility in the length of tooling combinations, up to a maximum of 10 times diameter and can run on nearly every major spindle interface. All tools are coolant-through and have three different insert holder options per head size. The tried-and-true EWN analog head features a dial with Ø.0005"/div setting accuracy (.0001" w/ Vernier).  

The integral design of these Smart Damper heads shortens the distance from the damping mechanism to the cutting edge, which is the source of vibration. This produces higher damping effects to the tool assembly to minimize the chatter or vibration, thus achieving better surface finishes and improved metal removal rates.
