Sandvik Coromant Damping Mechanism Enhances Turning Adapters

Sandvik Coromant has upgraded the damping mechanism for its Silent Tools turning adapters for consistent performance and improved surface finish during internal turning operations at long overhangs. The adapters integrate seamlessly with the company’s latest generation of CoroTurn SL cutting heads, which feature side-oriented internal through coolant.

The Silent Tools toolholding system is said to aid machining at long overhangs by effectively damping vibrations. Now, 33 cylindrical and Coromant Capto items from the turning adapter range (diameters 16-25 mm and ⅝"-1") have been improved and equipped with an overhauled and refined damping mechanism. According to the company, Silent Tools turning adapters enable improved consistency and machining repeatability over all available length-to-diameter ratios for a more reliable and high-performing product.

To further provide optimal performance and boost productivity, a new generation of CoroTurn SL cutting heads for small diameters (sizes 16 and 20), featuring side-oriented internal through coolant, has been developed to integrate with the upgraded turning adapters.

“These CoroTurn SL cutting heads benefit from Silent Tools technology, which provides improved stability performance,” says Daniel Conessa, global product manager of turning at Sandvik Coromant. “These two products work together to enhance component quality, increase machining process stability, reduce scrap and unnecessary rework, as well as minimize unplanned machine stops. Furthermore, downtime will be reduced due to better chip control, which is one of the main issues when boring long overhangs in small diameters.”

The upgraded Silent Tools turning adapters in sizes 16 and 20 mm (⅝" and ¾") seamlessly integrate with these CoroTurn SL cutting heads in sizes 16 and 20, which feature side-oriented internal through coolant. Additionally, Silent Tools turning adapters in size 25 mm (1") are suited for existing CoroTurn SL cutting heads in size 25 with high-precision coolant. When combined with the corresponding adapters, these cutting heads can provide all of the benefits previously mentioned.
