We propose an original route to process diamond wires, denominated In Situ Technology, whose fabrication involves mechanical conformation processes, such as rotary forging, copper tubes restacking, and thermal treatments, such as sintering and recrystallisation of a bronze 4 wt.% diamond composite. Tensile tests were performed, reaching an ultimate tensile strength (UTS) of 230 MPa for the diameter of Æ = 1.84 mm. Scanning electron microscopy showed the diamond crystals distribution along the composite rope during its manufacture, as well as the diamond adhesion to the bronze matrix. Cutting tests were carried out with the processed wire, showing a probable performance 4 times higher than the diamond sawing discs, however its probable performance was about 5 to 8 times less than the conventional diamond wires (pearl system) due to the low abrasion resistance of the bronze matrix, and low adhesion between the pair bronze-diamond due to the use of not metallised diamond single crystals.

Mermer işletmeleri için vazgeçilmez bir üretim yöntemi olan Elmas Tel Kesme Yönteminde, Elmas tellerin kesim performansları işletmelerin rantabl olarak çalışması ve devamlılıkları ile ilgili olarak son derece önemlidir. Bu çalışmada Burdur İli sınırları içinde faaliyet gösteren Çelikkol Petrol Mermer San. Ve Tic. Ltd. Şti.'ne ait Karamanlı Bej Mermer Ocağında kullanılan farklı firmalara ait elmas teller ile kullanılan Tel Kesme Makinaları incelenerek bir araştırma yapılmıştır. Yapılan bu araştırma da; elmas tellerdeki aşınma-kesim performans değerlendirmesi yapılmıştır., In Diamond Wire Cutting Method, is an indispensable production method for marble enterprises, Diamond Wire Cutting performance is extremely important for companies?s continous profitable working. In this study, different Wire Cutting Machines, produced by different firms were examined and different Diamond wires were used in Karamanlı Beige Marble Quarry which is owned by Çelikkol Petrol Marble Industry Trade Ltd. Comp. which operates within the provience of Burdur in Turkey. In this study, diamond wires wear-cutting performance has been evaluated.

Stone cutting with diamond wires results in the progressive and concurrent wear of the natural stone and the cutting tool (diamond wires - diamond beads). This phenomenon has been investigated since the beginning of stone machining, but there are still several open questions concerning the parameters controlling it. The aim of this study is to establish correlations between the natural stone mineralogical composition and the diamond wires cut performance in terms of efficiency, productivity and diamond beads consumption. This investigation requires a multidisciplinary approach. Microscopic analysis have been done in order to investigate the wear processes of the diamond beads in terms of super-abrasive grains (diamond grits) damage and pull out. Petrographic analysis and mineralogical investigation have been considered in order to correlate the removal rate during the cutting action with the characteristics of the stones. Muds derived from cutting have been characterized for the complete comprehension of the cutting process. The erosion analysis concerned both stone debris and diamond beads, characterizing both the metal powder and super-abrasive grains (diamond) in the cut waste (mud). Moreover, the metal matrix is the core of the diamond wire technology and it drives cutting performance and efficiency., International Conference on Stone and Concrete Machining (ICSCM), Vol 3 (2015)
