    The principle of diamond wire saw cutting

    In the 1990’s, in order to solve the processing problem of large size silicon wafer, jigsaw machining technology are widely used to cut large size silicon wafer into blocks and pieces in the international marketing. Early jigsaw machining technology applied bare wire and free abrasive. In the process of machining, the free abrasive are added into wire and mechanical parts as the third party to cut. This technique is successfully used in processing of silicon and silicon carbide. In order to further shorten processing time, as well as on other hard material and ceramic, diamond abrasive will be fixed to a metal wire in a certain way, which compose a fixed diamond wires saw. As shown in figure, cutting lines with high-speed reciprocating motion drive the slurry to the cutting area, which makes the abrasive particles (SiC particles) in the mortar and the surface of silicon rod make high speed grinding. Because the abrasive particles have very sharp edges and its hardness is greater than the hardness of silicon rods, the contact area of silicon rod and diamond wires saw are grinded out gradually by mortar. Thus the effect of cutting will be achieved, and meanwhile the mortar also can take away a lot of hot produced in the grinding. In the process of cognition of diamond wire saw cutting mechanism, many researchers believe that the micro cutting movement of diamond grits is a scroll and embedded process. They put forward the "scroll - embedded" model. ChinShine reachers put forward diamond wire sawing force drives on the abrasive grits rolling along the cutting surface, squeezing and embedded abrasive cutting surface at the same time. Consequently there is a flake piece of chip and surface crack, forming the big cutting function. ChinShine researchers pointed out that in "scroll - embedded" model, the particle movement also includes scratches, in addition to the rolling and embedded. All three work together for cutting. Bhagavat and some researchers considered the effect of pulping in this model and believe that the diamond saw wire leads free abrasive cutting silicon ingot of small area, and the movement of diamond wires saw and grinding pulping form a elastic fluid dynamic environment. They can use the finite element method (fem) to analysis the elastic fluid dynamics model of diamond wires saw and silicon ingot to get the function of diamond wire walking speed, viscosity of grinder and cutting conditions. Then they draw the conclusion: pulping film thickness is greater than the average particle size, is the flow of the abrasive cutting.

  • The reason why diamond saw blades often fail to cut

    The reason why diamond saw blades often fail to cut

    In the process of using the diamond saw blade, it is often found that the cutting cannot be carried out. In our production, this situation is attributed to the insufficient exposure of the diamond in the diamond segment。 As mentioned above, the cutting process is the process of constant exposure and constant shedding of diamond. The key is the ability of metal powder to hold diamonds, the cobalt is the most import in metal powder. In many cases, the diamond saw blade cannot cut because the diamond in the surface has fallen off, and the diamond inside has not been exposed or only exposed little bit. Whether the cutting object is easy or not, in the cutting process mainly depends on the density of the cutting object. The more sparse the density is and the less hardness is, the easier it is to cut, such as red bricks, concrete, refractory bricks, etc. The more compact the density and the higher the hardness, the more difficult it is to cut, such as marble, granite, basalt, etc. That is why different cutting objects need to select different diamond saw blades. When metal powder has good holding ability on diamond segment, we need to sharpen the diamond saw blade first. The most commonly used and easiest way to sharpen the edge is to cut red bricks, concrete or refractory bricks for a short time, so that the diamond could exposed in time. On the other side, the sparse density can be used to sharpen the diamond saw blade, of course, cutting is not a problem. For cutting this kind of low density, it's good as long as it is durable.

  • What is the affection on distance of diamond segments?
    Oct 15 , 2020

    What is the affection on distance of diamond segments?

    The distance or space affect the diamond disc cutting performance. Different blade slot and segment quantity will decide the distance among the diamond segments. Narrow slot cores:distance between diamond segments is 1/16" or less. Narrow slot is specified a smooth cutting which is essential as in cutting marble tile, glass and ceramic materials, porcelain. The cutting action will be smoother than the continuous rim diamond disc with the bonus of increase disc life. Standard Slot Blade:key slot: typically have 1/16" to 3/16" spacing between diamond segments. This recommended for general purpose cutting on materials where chipping and  smooth surface finish is not very important. Key slot/medium distance will tend toward free, fast, cutting efficiency and provide better circulation of coolant. The key slot or standard slot is adopted by the stone diamond cutting disc, such as granite diamond cutting disc. Wide Slot Blade:typically have slot width 5/16" to 3/8" and segment spacing to 1/2" or more. This type provides maximum chip removal and coolant circulation and reduces further the contact area. The wide slot diamond cutting disc is excellently suited to soft, loosely bonded, abrasive materials. Such as asphalt diamond cutting disc, wall cutting disc.

    Why use vacuum brazed diamond grinding wheel disc for marble?

    Related Name: Vacuum brazed diamond grinding wheel, Vacuum brazed diamond profile grinding wheel Vacuum brazed diamond grinding wheel is one of the most popular for marlbe edge grinding, it is applied with fused diamond technology. Its surface is high temperature welded diamond, not corundum abrasive of grinding wheel. Diamond is the hardest substance, with high hardness and sharpness, and a higher removal rate of the material. In addition, the new generation of diamond tool manufacturing technology – fusion technology can ensure that the diamond exposure is very high (up to 50%) and still firmly welded. Vacuum brazed diamond profile grinding wheel for marble is popular in Saudi Arabia, Palestine, and other middle east countries. The surface of a vacuum brazed diamond grinding  profile wheel is covered with a layer of diamond. Why the working life is so long? The key factor of the long life of marble vacuum brazed diamond grinding disc is technology and equipment. The new generation of welding technology ensures the high strength welding of the diamond. The high-performance vacuum brazed equipment ensures the excellent performance of the diamond. This ensures that diamond particles wear little during the use and do not fall off. The service life is greatly extended. What does pollution-free mean for the vacuum brazed diamond grinding wheel for marble? It means that during grinding process to marble slabs, vacuum brazed diamond profile grinding wheel will not lose sand and wear. No much chipping is produced, which is good for workers’ health. In addition, the traditional diamond segmented grinding wheels are not so fast.
