CoroTurn® SL

Customized tools for turning applications

CoroTurn SL is a modular system of adaptors 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 combination possibilities makes it ultimate for building a tool for machining complex components.

Stability in vibration-prone operations

The modularity of CoroTurn SL opens the door to Silent Tools™ damped 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 SL70 interface – an oval coupling which provides both excellent rigidity and accessibility, making it optimum 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.
