Wire saws with diamond beads for cutting stone blocks were first made in Japan in 1985. Since then, sales of diamond wire saw machines and wire have begun to grow as more of the country's stone factories have become aware of the advantages of this new tool. Although less than one third of Japanese stone factories are believed to be using diamond wire saws at present, the days of large diameter diamond circular saw blades are likely to be numbered now that toolmakers have perfected diamond wire not only for marble but also for cutting granite. In English Effects of granite microstructure on the sawing performance of diamond wires Korre, A. (Imperial Coll of Science, Technology and Medicine) Durucan, S. Source: International Journal of Surface Mining, Reclamation and Environment 14 2 2000 A.A. Balkema p 87-102 1389-5265 Abstract: The main objective of the diamond wire sawing tests presented in this paper was to investigate the diamond wire performance when sawing different granites in different orientations with respect to the rock microstructure. The work reported was carried out at the stoneyard, using stationary machines, and by sawing granite blocks free from major discontinuities. The test blocks were cut in two different directions, such as the freeway and/or the toughway, defined either by the crystal or by the microfracture orientations. Over 120 square metres of sawing were performed in each orientation at two different quarries. The data was analysed applying advanced statistical techniques. The diamond bead wear rate observed for the cuts along the toughway was found to be significantly higher than that observed for the freeway cuts. However, the comparison of wire performance along two parting planes, either mineralogical or physical, has shown that the difference in the wire performance was insignificant. In English 1 Refs.

Economic production Contardi, Gianni Luigi Source: Industrial Diamond Review v 53 n 558 May 1993 p 256 0019-8145 Abstract: An Italian company has developed a new machine and mold system that is highly flexible in operation and provides an economical method for the manufacture of diamond-impregnated beads for wire saws. The low cost of the system derives essentially from the assembly of the electrographite mold in which the bead is sintered. What makes this new machine a highly advanced product is its versatility; it is possible not only to vary the bead production rate, but also to change the type of production. In English EI94041268192 Development of a resinoid diamond wire containing metal powder for slicing a slicing ingot Enomoto, Toshiyuki (Ricoh Co Ltd) Shimazaki, Yutaka | Tani, Yasuhiro | Suzuki, Mari | Kanda, Yuichi Source: CIRP Annals - Manufacturing Technology v 48 n 1 1999 Hallwag Publ Ltd p 273-276 0007-8506 Abstract: Loose-abrasive wire sawing widely employed for slicing silicon ingots has problems of dirty working environment and inefficiency. Fixed-abrasive wires, namely electroplated diamond wires and resinoid diamond wires, have been developed to overcome these problems. Resinoid diamond wires, which can be produced at a lower cost, can be put to practical use, but they have a low breaking twist strength. In this study, metal powder is added to the resinoid bond to strengthen it. A series of experiments revealed that the breaking twist strength, heat resistance, tool wear resistance, and slicing efficiency of this wire are significantly improved. Brazed diamond grid: a revolutionary design for diamond saws Sung, C.-M. (China Grinding Wheel Corp) Source: Diamond and Related Materials 8 8 Aug 31-Sep 4 1998 1999 Sponsored by: De Beers Industrial Diamond Division (Pty) Ltd; Foundation for Research Development; Japan New Diamond Forum; Kobe Steel USA Inc.; Norton Diamond Film Elsevier Sequoia SA p 1540-1543 0925-9635 Abstract: About 250 tons of industrial diamonds are consumed world wide each year as superabrasives for cutting, drilling, sawing, grinding or polishing materials. Sawing constructional materials (e.g. rock and concrete) accounts for about one-third of the diamond used but with over half of the total value. However, <10% of the diamond is actually worn out in sawing the work material, the bulk is wasted primarily because the distribution of grits is poor and the bonding of diamond is weak. Diamond grits in conventional tools are held in matrix either by electroplated nickel or sintered metal. As a result, these grits are distributed randomly and they are buried mechanically. The segregation of diamond grits often results in densely and sparsely spaced regions. Thus, some grits are wasted due to redundancy; and others, shattered because of overload. Moreover, as the mechanical retention force is weak, all grits are easily knocked off by the strong impact force generated during cutting. Diamond grits can now be set in a grid pattern and they are brazed firmly in the tool. The controlled spacing of diamond allows optimal performance of each grit with minimal waste. The chemical bonding further prevents premature loss of the grit. Moreover, brazed diamond can protrude higher for aggressive cutting. The new technology has been applied to make diamond wire saws with half the amount of diamond used as compared with conventional diamond wires. The brazed diamond grid allows a two-fold increase of cutting speed over conventional diamond saws without compromising the life. If this technology is applied to other types of diamond saws, the result would be a dramatically improvement of productivity accompanied by a sizable reduction of cost.
