CoroTurn® SL

Customized tools for turning applications

CoroTurn® SL is a modular system of adapters and cutting heads with which you can build customized tools for a variety of turning applications with a minimum amount of items. The robust coupling and many possibilities for combinations make it ideal for building a tool for machining complex components.

Stability in vibration-prone operations

The modularity of CoroTurn® SL gives you the option to use Silent Tools™ dampened boring bars. This solution ensures maintained productivity and close tolerances in operations with long overhangs and other vibration-prone situations. As the same boring bar can be used for various types of cutting heads, you can use it for several operations.

Extra clearance when machining large components

CoroTurn® SL includes the SL70 interface—an oval coupling that provides excellent rigidity and accessibility, making it optimal for profiling and grooving operations on large components. Clearance is applied for external and internal machining, so each cutting head can be used in both configurations.
