Ideal for the high speed finish machining of inconel, NTK's new JP2 turning grade (part of the new Bidemic line of inserts) is capable of machining at 15 times the speed of high-end carbide insert grades.
The new series of coated multi-tipped brazed inserts are capable of running at a surface speed in excess of 500m/minute. When compared to market leading CBN grades, the JP2 provides superior wear and notching resistance whilst delivering superior surface finishes, according to the cutting tool manufacturer. Whereas many ceramic grades have historically witnessed edge chipping when finish cutting Inconel, the new JP2 delivers tool life and improved consistency.
Suitable for machining at cutting depths of 0.1 to 3mm on heat resistant alloys such as Inconel, Rene, Waspalloy, Hastalloy and 718 Stainless, the JP2 has been developed for ultra-high speed cutting. From a productivity perspective, the JP2 increases productivity and tool life by four times. This is thanks to a TiN coated insert that has an exceptionally strong brazing to withstand the high temperatures during machining.
For the end user, the result is noticed with an insert grade that can meet expectations of the demanding aerospace sector. The JP2 is available in a range of insert sizes and geometries to correspond with existing tool holders from the NTK catalogue.
