High Speed Finish Turning of Inconel 718 Using PCBN Tools under Dry Conditions
Metals, 2018 Inconel 718 is a superalloy, considered one of the least machinable materials. Tools must withstand a high level of temperatures and pressures in a very localized area, the abrasiveness of the hard carbides contained in the Inconel 718 microstructure and

The effect of High Speed Machining on the Crater Wear Behaviour of PCBN Tools in Hard Turning.
Procedia Manufacturing, 2019 This study investigates the effect of high speed cutting on the crater wear behaviour of PCBN tools in continuous cutting. Turning tests were performed using two PCBN grades, one high CBN content (PCBNH) and one low CBN content (PCBN-L) at two cutting ...

Research on PCBN Tool Dry Cutting GCr15 [PDF]
Machines, 2018 This paper is based on the theoretical analysis designs of a dry cutting orthogonal test in order to study a phenomenon that the radial force is larger than the main cutting force when a PCBN (polycrystalline cubic boron nitride) tool hard turns GCr15.

Evaluation of machining performance of STAVAX with PCBN tools [PDF]
The International Journal of Advanced Manufacturing Technology, 2004 A study was undertaken to investigate the wear characteristics of polycrystalline cubic boron nitride (PCBN) cutting tools and surface integrity during machining of STAVAX (specialised stainless steel) with and without coolant. Plastic deformation and formation of overtempered martensite and white layer (untempered martensite) were the dominant ...
