Halesowen-based Sandvik Coromant, a cutting tool and tooling system specialist, has upgraded the damping mechanism for Silent Tools turning adaptors for an even more consistent performance and improved surface finish during internal turning operations at long overhangs.

With close to 50 years of experience in preventing vibration, tool-holding system Silent Tools from Sandvik Coromant has aided machining at long overhangs by effectively damping vibrations. Now 37 cylindrical items from the turning adaptor range, diameters 32–100mm, have been improved and equipped with an overhauled and refined damping mechanism.

Åke Axner, global product manager – machine integration at Sandvik Coromant, said: “The damping mechanism has been substantially upgraded compared to the former generation of Silent Tools turning adaptors. The damper body, previously requiring manual fine-tuning, is now calibrated and assembled by a machine. This automation results in a highly precise and predictable frequency area, perfectly matched to each adaptor’s intended overhang and application. This means that they are more efficient at countering vibration forces at long overhangs than ever before.”

Thanks to the upgrade, Silent Tools turning adaptors will ensure improved consistency and machining repeatability over all available length-to-diameter ratios, for a more reliable and high-performing product. To further ensure accuracy in set-ups and optimal tool health, the upgraded turning adaptors are accompanied by the introduction of digital device Tool Status Checker.

Mr Axner continued: “Tool Status Checker is designed for seamless monitoring of Silent Tools turning adaptors on a Windows tablet or computer. It is compatible with all versions of our turning adaptors. Just snap it on to the adaptor’s serration lock interface using the built-in magnet, download the software, and you’re ready to go.”

With Tool Status Checker’s centre height setting feature, a precise set-up is guaranteed every time, while the temperature monitoring feature ensures that the adaptor is always working within its specified temperature range.

Axner highlights another valuable feature. He said: “It is now possible to make sure that the adaptor is operational before machining starts. Thanks to Tool Status Checker’s tap-test feature and the included hammer, it is easy to compare the current set-up to a previous one and get a go or no-go result directly in the software. This is a feature that our customers have long requested, and we are delighted to deliver it to them.”
