Evaluation of machining performance of STAVAX with PCBN tools [PDF]

open access: yesThe 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 ...
