Smart Damper products Designed for Deep-Hole Boring

​The EWD Smart Damper damps vibrations and reduces chatter in deep-hole finish boring and extended-reach face milling applications – thus achieving better surface finishes and improved metal removal rates.

​For precision machining of deep bores, it has previously been necessary to choose low cutting data in order to prevent vibrations, which massively increases processing time. The EWD Smart Damper overcomes this problem, and enables high cutting parameters to be used. This means that extremely short turnaround times can be achieved, which improves productivity by up to a factor of ten.

Features

• Patented Smart Damper technology for vibration free boring
• Coated tool body for complete protection against corrosion
• Body protection grade: IP 69K
• LCD Display with a resolution of 0,001 mm Ø
• Direct measuring diameter allows corrections in both directions

Smart Damper products are designed for deep-hole boring with BIG KAISER’s CKB modular boring system, and also for extended reach milling with both inch- and metric-pilot shell mills and face mills.

The original rollout of the Smart Damper for finish boring included an integral BCV50, BBT50 and HSK-A100 tool holder with a CKB modular connection at the business end. A BCV50 integral 1” shell mill holder was also available.

The next phase of the Smart Damper accounted for more flexibility towards assembling a more custom tool assembly.

A modular CKB Smart Damper Extension allowed customers to mount it to any combination of standard CKB shanks, extensions and reductions to create the exact tool configuration for their job.

At the same time, a modular thread-on face mill damper head extension was also developed to be used with matching basic holder with different interfaces and gauge lengths.

This new design for boring 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.

Big Kaiser tests have shown that deep holes free of vibration can be bored with an excellent surface finish with dramatic time savings. For example, with a projection length of 14.3” working with high-carbon steel at a cutting speed of 1,300 SFM, an impressive feed rate of 11.4 IPM was achieved with the EWN41 Smart Damper.
