Suitable for machining HRSA materials at speeds of 480 m/min, the new JP0 is the latest addition to the NTK range of Bidemics, a material that can improve productivity for aerospace manufacturers that are regularly cutting challenging materials. Now, the newest evolution of this material technology from NTK demonstrates improved wear resistance and performance.

Capable of machining at cutting speeds up to 15 times faster than carbide and CBN alternatives, the NTK JP0 demonstrates wear resistance and consistency to deliver performance when machining all heat resistant superalloy materials. The new JP0 insert grade is suitable for running at cutting speeds from 180 to 500 m/min with a feed rate of 0.05 to 0.2 mm/rev and a depth of cut from 0.1 to 0.7 mm.

Currently, NTK has introduced the new high-performance finish turning grade in three different designations, the CNGA, DNGA and VNGA geometries. The 4.76 mm thick CNGA and DNGA inserts are available with a 0.4, 0.8 and a 1.2 mm corner radius and an IC of 12.7 mm. The VNGA insert designation is available with a 0.4 and a 0.8 mm corner radius with a 9.525 mm IC; all three designations demonstrate outstanding quality with the 0.04 mm honed edge preparation.
