Expanded Smart Damper Lineup



BIG Kaiser has introduced the EWN and EWD Smart Damper precision boring heads with a patented damping system designed to eliminate vibration in deep-hole finish boring.

The integral design of these new 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.

"For precision machining of deep bores, it had previously been necessary to program low cutting parameters in order to prevent vibrations, which unnecessarily increases machining time," said Jack Burley, V.P. Sales and Engineering of BIG Kaiser. "The EWN/EWD Smart Damper overcomes this problem and enables the use of high cutting parameters. This means that extremely short turnaround times can be achieved, which improves productivity by up to a factor of 10."

With a projection length of 14.3" working with high-carbon steel at a cutting speed of 1,300 SFM, a feedrate of 11.4 IPM was achieved with the EWN41 Smart Damper, according to tests conducted by BIG Kaiser.

The newest Smart Damper product is equipped with either the EWN analog boring head series or the latest digital technology in the EWD series. The EWN heads feature a dial with O.0005"/div setting accuracy (.0001" w/Vernier). The EWD heads have a large digital screen, which clearly shows adjustments to an accuracy of O.00005", thus helping to minimize operator errors and remove the need for complicated Vernier markings. The digital display can be reset to zero at the push of a button and has an auto power off function, while the current position of the cutting edge will be shown automatically again due to direct path measurement when the tool is switched on.

The new Smart Damper is compatible with BIG Kaiser's modular CK/CKB system, which means that the length of tool combinations can be freely selected up to a maximum of 10 times the diameter, and are capable of being run on nearly every major spindle interface. All tools are coolant-through, and due to three different insert holders per head size, a large boring range is possible. For example, the EWN and EWD68 heads can bore a range of O2.677"-5.906". All BIG Kaiser EWD heads have a seal rating of IP 69K.
