5) The manufacture of diamond wire beads by free sintering
1.1) Bead for cutting marble or calcareous materials
Sizing of the bead - The outer diameter, the lenght of the diamond-
1.2) Choice of bond for free sintering - General considerations, bond for
cutting marble, the cold mould, final note.
1.3) Choice of diamond type, granulometry and concentration - Diamond
types, diamond granulometry, the a ratio, number of tips on the cutting
surface, osculation probability, notes.
1.4) Bead preforming (cold pressing) - Powder mixing, cold forming
1.5) Sintering and brazing - Free sintering practical procedure, sintering
