SpiroGrooving - an innovative method for seal ring grooves developed by Sandvik Coromant ensures high output of quality components and meets tough security demands. Used with the CoroBore XL system, it utilizes a spirograph tool path to create close-tolerance seal ring grooves in a very secure and productive way
Machining challenges Requiring close tolerances and high-quality 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 utilizes a spirograph tool path to create close-tolerance seal ring grooves in a very secure and productive way.
High quality and process security This solution is ideal for making seal ring grooves in pre-clad machining of steel and stainless steel. The unique internal coolant feature of CoroBore XL facilitates machining in advanced materials. Roughing and finishing are carried out in the same operation, which significantly reduces machining time and improves productivity. Altogether, this ensures high output of quality components and process security when machining seal ring grooves.
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.
