Iscar's anti

May 08, 2023

Iscar has recently developed a comprehensive series of high-quality internal boring bars for different insert geometries, covering all machining applications from 4xD to 10xBD.

The line includes three types of boring bars: solid steel, solid carbide and anti-vibration. The maximum overhang for solid steel boring bars is up to 4xBD. This limitation is due to the fact that machining with a longer length of steel shank (more than 4xBD) can induce unwelcome vibrations due to the elasticity and characteristics of the steel.

In order to limit the vibration on a higher overhang of more than 4xBD and up to 6xBD, the use of solid carbide boring bars is recommended. Solid carbide possesses a coefficient of elasticity that is three times higher than that of steel, making it a good option for this application.

However, when the machining of high overhangs of more than 6xBD is required, even the use of a solid carbide shank can cause vibrations. Iscar created the WHISPERLINE anti-vibration boring bars to significantly reduce and even totally eliminate vibrations when working with a high overhang from 7xBD to 10xBD.

Situated inside these ingenious tools is a unique damping mechanism that consists of a heavy mass that is supported by a rubber spring element containing oil to increase the required dampening effect.
