Title: Roy Derrick Achilles: Innovator in Polycrystalline Diamond Technology
Introduction
Roy Derrick Achilles is a notable inventor based in Bedfordview, South Africa. He has made significant contributions to the field of abrasive technology, particularly through his innovative work with polycrystalline diamond abrasive elements. With a total of 13 patents to his name, Achilles has established himself as a key figure in the industry.
Latest Patents
One of his latest patents focuses on polycrystalline diamond abrasive elements, specifically designed for cutting applications. This invention features a table of polycrystalline diamond that is bonded to a substrate, typically a cemented carbide substrate, along a non-planar interface. The unique design includes a cruciform configuration for the non-planar interface, which enhances the performance of the cutting element. The polycrystalline diamond exhibits high wear resistance, with a region adjacent to the working surface that is lean in catalyzing material and another region that is rich in catalyzing material. Notably, the region lean in catalyzing material extends to a depth of 40 to 90 microns, which is significantly shallower than in prior art. Despite this shallow region, the polycrystalline diamond cutters maintain wear resistance, impact strength, and cutter life comparable to traditional cutters, while requiring only 20% of the treatment times.
Career Highlights
Throughout his career, Roy Derrick Achilles has worked with prominent companies, including Baker Hughes Corporation. His expertise in abrasive technology has allowed him to develop innovative solutions that have advanced the industry.
Collaborations
Achilles has collaborated with notable professionals in his field, including Klaus Tank and Bronwyn Annette Roberts. These collaborations have contributed to the development of cutting-edge technologies in abrasive elements.
Conclusion
Roy Derrick Achilles is a distinguished inventor whose work in polycrystalline diamond technology has made a lasting impact on the industry. His innovative patents and collaborations highlight his commitment to advancing abrasive technology.
