Abstract:
A method is described for producing a sawing bead for use in a sawing cord. Sawing cords are used for cutting hard and brittle materials. In the method, laser cladding is used to form an abrasive layer on a small metallic tube (204) or sleeve. The abrasive layer (220) comprises a metal matrix material in which abrasive particles such as diamond, cubic boron nitride or other hard cutting materials are embedded. The metal matrix material preferably comprises an active metal that improves wetting and adhesion of the abrasive particles. Although the abrasive particles are relative large—with a particle size in excess of 100 μm—they are evenly distributed throughout the abrasive layer. This is achieved by letting the tube (204) rotate relative to the laser cladding system possibly in combination with a relative axial movement so that the cladding track loops on itself thereby forming an abrasive layer (220). Additionally the method allows to shape the sawing bead for improved geometrical tolerances and centricity. Production times are less than ten seconds per bead and the method is easily automated.
