Definitions

  • the present invention relates to the cutting and grinding tools, such as the cutting segments of diamond tools, which are typically used in cutting and drilling various hard and fragile materials, such as granite, marble, concrete, asphalt, etc. More particularly, the present invention relates to the uniform distribution of abrasive particles such as diamond grits on the segments of cutting tools to increasing the cutting efficiency.
  • Synthetic diamonds are the hardest abrasive material currently known, and they have been widely used as super-abrasives on cutting and grinding tools. Diamond tools are particularly used to cut and grind rocks in machining stone and other structural components. Diamond tools mainly have cutting segments on which diamonds or other abrasive particles are distributed. The cutting segments are fixed on the tool bodies.
  • a satisfactory structure of diamond saw blades is where the diamond particles have a relatively large exposed portion and proper spacing of particles to improve the excluding of debris and the transporting of cooling fluid, thus improving the cutting efficiency and lengthening the useful life of the tools. Uniform distribution of abrasive grits can also improve safety in their manufacture.
  • a typical abrasive tool such as a diamond saw blade, is manufactured by mixing diamond particles (e.g. 40/50 U.S. mesh) with a suitable support matrix (bond) powder (e.g. cobalt powder of 1.5 micrometer in size). The mixture is then compressed in a mold to form the desired shape. This “green” form of the tool is then consolidated by sintering at a temperature between 700-1200° C. to form a single body with a plurality of abrasive particles therein. Finally, the consolidated body is brazed to a tool body, such as the round blade of a saw, to form a cutting tool.
  • a suitable support matrix (bond) powder e.g.
  • drilling and sawing applications may require a larger-sized (20 to 60 U.S. mesh) diamond grit to be mixed with a metal powder.
  • the metal powder is typically selected from cobalt, nickel, iron, copper, bronze, or alloys thereof, and/or mixtures thereof.
  • a smaller-sized (60/400 U.S. mesh) diamond grit is mixed with either metal (typically bronze), ceramic/glass (typically a mixture of oxides of sodium, potassium, silicon, and aluminum) or resin.
  • diamonds are much larger than the matrix powder, and is much lighter, it is very difficult to mix the two to achieve uniformity. Moreover, diamond particles can still segregate from metal powder in the subsequent treatment, such as when pouring the mixture into a mold, or when the mixture is subjected to vibration.
  • One method used in an attempt to make the diamond distribution uniform is to wrap diamond particles with a coating of matrix powder.
  • the concentration of diamond particles in each diamond tool is tailored for a particular application. The concentration determines the average distance between diamond particles. If one thickly coated diamond mixes the coated particles together, the distribution of diamond would be controlled by the thickness of coating and may become uniform. Additional metal powder may be added as an interstitial filler between these coated particles to increase the packing efficiency so that the consolidation of the matrix powder in subsequent sintering would be easier.
  • Dr. Song Jian Min of Taiwan has invented a two-dimensional method, firstly providing a layer of support matrix, and disposing abrasive grits in the support matrix layer in a desired pattern. After the diamond particles are plated into the metal matrix layer according to a predetermined pattern, the process may be repeated until a desired number of layers have been formed. The layers are then assembled to form the desired three-dimensional body. Subsequently the diamond tool is consolidated to form the final product.
  • the detailed above-mentioned method is as follows: forming a thin layer of bonding matrix (i.e. a two-dimensional body); placing a template on the bonding matrix, with the template having a plurality of apertures formed therein which are sized to receive a abrasive grit of a particular size, with one particle being disposed in each aperture; and, as the particles are filled into the apertures, they are subjected to pressure or moved into the bonding matrix.
  • the abrasive particles are small to 40/50 U.S. mesh, it is imposable to fill the apertures with abrasive particles one by one, and so this method cannot achieve industrialization.
  • the distance between diamond or other abrasive particles determines the work load each particle will perform. Improper spacing of the abrasive particles will lead to premature failure of the abrasive surface or structure. If the abrasive particles are too close to one another, some of the particles are redundant and add to the cost. Moreover, these non-performing particles can block the passage of debris, thereby reducing cutting efficiency.
  • the distance between the grits will be optimized according to the cutting materials and cutting conditions. It has be found that in practice, 85% of the distances between diamond grits on uniform distributed saw blade are 2 mm-5 mm, while on traditional saw blades, this percentage is only 60%. The increasing of diamond content weakly affects the work load, but the applicable cutting times are lengthened markedly, thus the cutting efficiency is increased and useful time of the saw blade is lengthened.
  • Diamond concentration when the concentration of diamond increased, the useful time of uniform distributed diamond will be lengthened in geometric series, and maintaining favorable cutting and sawing capability at the same time, but when the concentration increased more, the cutting and sawing capability will be reduced.
  • the exposed height of diamond particularly affects the sawing efficiency and the useful time of the saw blade, it is rest with the size and the distribution of diamond and the hold of the sheet. So, the uniform distribution of diamond or other abrasive particles on matrix will markedly affect the cutting and grinding tools.
