Diffusion and oxidation wear of PCBN tool based on thermodynamics

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2010
The rules of diffusion wear and oxidation wear for PCBN cutting tools were analyzed based on thermodynamics theory. Dissolution concentrations in typical normal workpice materials of PCBN tool material at different temperature were then calculated. Diffusion reaction rules in high temperature were developed and analyzed using the Gibbs free energy ...

Optimizing PCBN cutting tool performance in hard turning

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2008
Surface finish, in addition to tool wear, is an important aspect of PCBN tool performance in hard turning. A set of experiments that focused on the effects of corner radius, chamfer angle/width, and edge radius in addition to severity of interruption and speed/feed at constant depth of cut were performed.

Machining Abrasion-Resistant Hard-Facings with Pcbn Tools

2002
Iron-based hard-facings are a popular choice for abrasion resistant materials in industries as diverse as mining and food processing. Alloys forming chromium carbides dispersed in a relatively soft matrix are particularly effective because these carbides are usually present as relatively large micro-constituents, which present large surface areas to ...
