Solution for seal ring groove machining challenges
Requiring close tolerances and highquality surface finish, seal ring grooves is a critical feature on many oil and gas components. Conventional methods for machining seal ring grooves often suffer from slow production and poor process security. Multiple-operation approach incorporating both roughing and finishing sequences is another time thief. The tools that are being used are single point or plunging cutters that are prone to vibration. Adding to the challenges is the common use of difficult-to-machine materials such as solid Inconel 718 and cladded Inconel 625. SpiroGrooving is a machining method used with the CoroBore XL system that utilises a spirograph tool path to create closetolerance seal ring grooves in a very secure and productive way.
How it works
SpiroGrooving uses a circular spirograph tool movement in a taper. This reduces chip thickness, enabling light cutting action and increased feed. Parts of the insert cutting edge have an interrupted cutting behaviour, eliminating long chips tangling to the tool and spindle. With a unique NC-code generator, SpiroGrooving is programmed just in a few easy steps.
