The document discusses various fabrication technologies for diamond beads used in cutting tools, including traditional methods like electroplating, hot pressing, and pressureless sintering. It then introduces a new technology called Diamond Injection Moulding that allows intricate bead geometries and has advantages over traditional methods like lower costs and higher performance. Testing of a bead with a new double bulge geometry in a full-scale plant found it could cut wires at a higher speed, resulting in over a 15% cost savings despite slightly reduced lifetime.

- 16. A cost saving higher than 15% is possible
- 17. A new process based on Diamond Injection Moulding has been developed and patented. The process allows to produce tools with intricate geometries not possible to make so far With the new process a innovative diamond bead has been produced and tested in a full scale plant. The new double bulge geometry allows the wire to cut with a higher speed, that determines a cost saving higher than 15% in spite of the slightly reduced wire lifetime Conclusions
