Comparative grinding performance assessments employing a precision 4-axis micro-machine for the machining of Ti-Al-4V have shown that the laser generated diamond micro-grinding tools produce significantly superior surface finishes to the dimensionally equivalently conventional diamond electroplated micro-grinding tools. In addition to demonstrating the robustness of grinding tools produced from solid diamond, the tests have highlighted the advantages of the layout of cutting elements which significantly extended the operating life of the tool through the even distribution of load across the cutting elements and efficient workpiece chip disposal.
