Diamond Wire Saw Structures and Manufacturing Forms

diamond wire saw is made up of a rope which fixes diamond beads in a certain gap. It consists of six parts as follows.

(1)Steel rope; 

(2)Diamond beads; 

(3)Steel ring, mainly used for fixed distance and isolation beads; 

(4)Separator sleeve, used for separating beads and stringing beads along the rope in a small range. The separator sleeve commonly contains spring sleeve, plastic sleeve, rubber sleeve; 

(5)Fixing ring; 

(6)Joint.

Before working, one end of the diamond wire saw should pass through two holes intersecting at one point in two holes drilled into marble in vertical or horizontal direction, and then the two ends of bead wire should be connected with a joint to a closed form.

Common manufacturing forms of diamond wire saw:

①烧结法。用粉末冶金方法将金刚石颗粒烧结成型。通常在外径处排列一层厚1一1.5~的金刚石颗粒层。此法使金刚石环具有均匀切削性能，使用寿命长，因具有自锐性能，可使环块始终保持锋利的切削性能，金刚石环块的选择可根据被加工材料选择不同的粗度、结合剂与硬度，以达到高效经济的目的。

(1) Sintering method. Diamond particles were sintered by powder metallurgy. Usually a layer of diamond grains with a thickness of 1-1.5~is arranged at the outer diameter. This method makes the diamond ring have uniform cutting performance and long service life. Because of its self-sharpening performance, the ring block can always keep sharp cutting performance. The choice of diamond ring block can be based on the material to be processed to select different roughness, binder and hardness, in order to achieve the purpose of high efficiency and economy.

②电镀法。本法在钢的基体上电沉积一层金刚石单晶而制成的，因此其工艺过程与一般的金刚石电镀产品相同。它用45#或40cr钢制造，以便于电镀及镀层的牢固结合，同时使其内孔能耐钢绳的摩擦。

(2) Electroplating method. This method is made by electrodepositing a layer of diamond single crystal on the steel matrix, so the process is the same as that of common diamond electroplating products. It is made of 45 or 40Cr steel, so that the plating and coating can be firmly combined, and the inner hole can withstand the friction of the steel rope.

③钎焊法。高温钎焊串珠中金刚石排列规则，分布合理，化学键结合与冶金结合并存，金刚石的把持力强，锯切速度高，锯切成本相对较低。

(3) Brazing method. The diamond in brazed beads at high temperature is arranged regularly and distributed reasonably. Chemical bonding coexists with metallurgical bonding, so the diamond has strong holding power, high sawing speed and relatively low sawing cost.
