NTK leads the way with new aerospace turning grade

For finish turning of HRSA materials, NTK cutting tools has now introduced its new JP0 Bidemics range of inserts.

Suitable for machining HRSA materials at speeds of 480m/minute, the JP0 is the latest addition to the NTK range of Bidemics – claimed by the manufacturer to be a revolutionary material that can greatly improve productivity for aerospace manufacturers 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 exceptional wear resistance and consistency to deliver outstanding performance when machining heat resistant superalloy materials. The new JP0 insert grade is suitable for running at cutting speeds from 180 to 500m/minute with a feed rate of 0.05 to 0.2mm/revolution and a depth of cut from 0.1 to 0.7mm.

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

The Japanese cutting tool manufacturer recommends that when turning heat resistant super alloys and other extremely challenging material types, manufacturers utilise button inserts from the Bidemics, Whisker and SiAlON series’ for heavy-duty rough machining followed by the NTK SiAlON range for semi-finish passes.
