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.

- boring
boring
Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.
- chatter
chatter
Condition of vibration involving the machine, workpiece and cutting tool. Once this condition arises, it is often self-sustaining until the problem is corrected. Chatter can be identified when lines or grooves appear at regular intervals in the workpiece. These lines or grooves are caused by the teeth of the cutter as they vibrate in and out of the workpiece and their spacing depends on the frequency of vibration.
