Used with CoroBore® XL System, SpiroGrooving™ utilizes spirograph tool path to create close-tolerance seal ring grooves. Parts of insert cutting edge have interrupted cutting behavior, eliminating long chips that can tangle tool and spindle. With internal coolant feature, CoreBore XL solution is suited for making seal ring grooves in pre-clad machining of steel and stainless steel components. Roughing and finishing are carried out in same operation, maximizing productivity.
