Title: Innovations by Torbjorn Selinder: Advancements in cBN Materials and Cutting Tools

Introduction

Torbjorn Selinder, an accomplished inventor based in Bandhagen, Sweden, has made significant contributions to the field of materials science through his innovative solutions in the realm of cutting tools and cBN materials. With a total of two patents to his name, Selinder's work exemplifies the intersection of engineering and inventive thinking.

Latest Patents

Selinder's latest patents highlight his expertise in the development of a method for creating cBN materials. This method involves several critical steps: starting with a powder mixture that includes cBN grains, aluminum, and a Ti(CxNyOz)a powder, the process then subjects this mix to milling, forming a green body, and undergoing a pre-sintering operation at temperatures ranging from 650 to 950°C. This creates a pre-sintered body, which is subsequently subjected to a HPHT operation to yield the final cBN material. The cBN material consists of cBN grains, Al2O3 phases, and a binder phase containing TiC, TiN, and/or TiCN, alongside W and Co, designed to maintain a quotient Q of less than 0.25.

Furthermore, Selinder has also developed a diamond composite cutting tool which integrates superabrasive compacts, such as silicon carbide diamond bonded composites, directly bonded to a tungsten carbide body during the sintering process. The innovative design includes a recess that allows for an interference fit with the superabrasive compact after processing, ensuring both performance and durability in cutting applications.
