Machining Method Developed for Seal Ring Groove Machining

SpiroGrooving, a method for seal ring grooves developed by Sandvik Coromant, is designed to ensure high output of quality components and meet tough security demands. "Seal ring grooves are a critical feature on many oil and gas components, requiring close tolerances and high-quality surface finish," said a company spokesperson. "Conventional methods for machining seal ring grooves often result in slow production and poor process security. Multiple-operation approach, incorporating both roughing and finishing sequences, is another challenge. The tools used are single point or plunging cutters that are prone to vibration. Difficult-to-machine materials, such as solid Inconel 718 and cladded Inconel 625, are often used, adding to the long list of challenges to overcome. SpiroGrooving is a machining method used with the CoroBore XL system that utilizes a spirograph tool path designed to create close-tolerance seal ring grooves in a secure and productive way.

"This solution is suitable for making seal ring grooves in pre-clad machining of steel and stainless steel. The internal coolant feature of CoroBore XL enables machining in advanced materials. Roughing and finishing are carried out in the same operation, thereby reducing machining time and improving productivity. This solution ensures high output of quality components and process security when machining seal ring grooves.

"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 behavior, eliminating long chips that can tangle the tool and spindle. With a unique NC-code generator, SpiroGrooving is programmed in a few easy steps."
