Electroplated Diamond Wire

The electroplated diamond wire is the oldest wire. The beads are made of an annular steel support on which the diamond grains are deposited by electrolysis; they have a remarkable robustness and biting capacity. The electroplated diamond wire is perfectly suited for sawing soft stones; it is most efficient for small cuts and for squaring-off blocks (small curvature radius). Compared with the impregnated diamond wire, the electroplated wire has the double advantage not requiring more power than 25 hp and needing a very limited cooling (from 10 I minimum to 20 I/min.).
The impregnated diamond wire has been designed for working all types of stone (included the hardest and most abrasive ones) and for improving the m2 sawn (some people call it the "long life" wire). The abrasive part of the bead consists of a ring with diamond impregnation the composition of which is similar to that of the segments of the gangsaw or circular saw blades. Economical advantage: the tool life of the impregnated diamond wire is often twice as long as that of the electroplated diamond wire; it costs however far less than twice the price of the latter. Technological advantage: the sawing speed of the impregnated diamond wire is practically constant during the whole tool life. The impregnated diamond wire requires a minimum power of 40 hp and a normal cooling, i.e. 20 to 50 I/min. according to the dimensions of the cut.
