Overcome vibrations in internal turning


Silent Tools™ is an anti-vibration technology that enables internal turning with long overhangs. Solutions are available to reach lengths of up to 14 times the bar diameter.

By using Silent Tools ™, productivity gains of up to 50% for shorter boring bars and up to 400% for longer overhang lengths are possible.

CoroTurn SL is a modular system with exchangeable cutting heads, allowing you to create a wide range of tool combinations from a small inventory of adaptors and cutting heads.

Need dimensions beyond our standard assortment? Tailor Made® lets you customize our advanced damping technology for optimal cutting performance, with quick quotes and reliable delivery.
With Silent Tools™ damped turning adaptors, vibrations are kept to a minimum, increasing safety and productivity. By minimizing disruptions during internal turning operations, Silent Tools™ turning adaptors will lower your cost per component for a more profitable and competitive business.
Thanks to a substantial upgrade of the damping mechanism, Silent Tools™ turning adaptors are more efficient than ever at countering vibration forces at long overhangs.
- The damper body used to require manual fine-tuning, but is now calibrated and assembled automatically by a machine
- This automation results in a highly precise and predictable frequency area, perfectly matched to the adaptor’s intended overhang and application
- The upgraded Silent Tools™ damping mechanism brings about a significantly more consistent performance across different length-to-diameter ratios when compared to the previous generation of turning adaptors
- This improvement translates into increased machining repeatability, providing an even more reliable and precise product
49 of our Silent Tools™ cylindrical turning adaptors (Ø16–25 mm and Ø32–100 mm), 96 adaptors with Coromant Capto® coupling (C3, C4, C5, C6, C8 and C10), 6 HSK-T adaptors (Ø32–60 mm) have been updated with the new damping mechanism.

Let us show you how the upgraded Silent Tools™ turning adapters redefine precision and consistency in internal turning operations.
With a legacy spanning over nearly five decades, Silent Tools™ turning adapters are now more efficient than ever at damping vibrations at long overhangs. Paired with the Tool Status Checker digital device, monitoring tool health has never been easier.
Highlights

Elliptical adapters are tailored for the machining of valve seat pockets. With these adapters and light-weight cutting heads, you can overcome challenges such as narrow entries and long overhangs.

Problems that originate from vibrations are frequently encountered in boring when machining with long overhangs. Damped tools can solve vibration issues and improve boring performance.

Many components and machine tools require long milling tool assemblies to reach into large components. Vibration risk is high, and the remedy is slow machining or damped tools.
