Definitions

  • the present invention relates to the improvement of cutting, grinding tools, such as the cutting segments of diamond tools and the other diamond tools, which are typically used in cutting and drilling various hard and fragile materials, such as granites, marbles, concretes, asphalts, etc. More particularly, the present invention relates to the uniform distribution of abrasive particles such as diamond grits on the segment of cutting tools to increasing the cutting efficiency.
  • Synthetic diamonds are the hardest abrasive material currently known: they have been widely used as super-abrasives on cutting and grinding tools.
  • the diamond tools are particularly used to cut and grind rocks in machining stone and the other structural components.
  • the diamond tools have cutting segments on which the diamond or other abrasive particles are distributed; the cutting segments are fixed on the tool bodies.
  • a satisfactory structure of diamond saw blade is that the diamond particles have a big exposed portion and a 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.
  • a uniform distribution of abrasive grits can also improve the safety in 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 right 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.
  • drilling and sawing applications may require a large-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, alloys thereof, and/or mixtures thereof; for grinding applications, a small-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.
  • diamond is much larger than the matrix powder, and it is much lighter than the latter, 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 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.
  • 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 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 that: firstly a thin layer of bonding matrix, i.e. a two-dimensional body, is formed. A template is then disposed on the boding matrix.
  • the template has a plurality of apertures formed therein which are sized to receive an abrasive grit of a particular size, with one particle being disposed in each aperture: as the particles are filled into the apertures, they may be subjected to pressure or moved into the boding matrix.
  • the abrasive particles are small to 40/50 U.S. mesh, and it is impossible to fill the apertures with abrasive particles one by one, so this method cannot achieve industrialization.
  • the distance between diamond or other abrasive particles determines the workload each particle will perform. Improper spacing of the abrasive particles will lead to premature failure of the abrasive surface or structure. Thus, if the abrasive particles are too close to one another, some of the particles are redundant and add the cost. Moreover, these non-performing particles can block the passage of debris, thereby reducing the cutting efficiency.
  • the distance between the grits will be optimized according to the cutting materials and cutting conditions. It has been found that in practice, 85% of the distance between diamond grits on uniform distributed saw blade is 2mm-5mm, while on traditional saw blade, this distance percent is only 60%. The increase of diamond content weakly affects the workload, but the applicable cutting times are lengthened markedly, thus the cutting efficiency increased and the useful time of the saw blade are lengthened.
  • Diamond concentration when the concentration of diamond increases, the useful time of uniformly distributed diamond will be lengthened in geometric series, and maintaining favorable cutting and sawing capability at the same time, but when the concentration increases 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 rests 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.
  • Object of the present invention is providing a method of arranging the abrasive particles uniformly on cutting and grinding tools, and the method can be industrialized.
  • One art of the present invention is to provide a sheet; a template, designed on the single-layer arranging requirement of diamond or the other abrasive particles, said template having a layer of adsorbent which can adsorb a single layer of diamond grits.
  • Said template comprises an adsorbent, wherein the adsorbent has a lower viscosity, a higher percent of condensate and a lower percent of solvent.
  • Said sheet is a paste: after the diamond is pressed into it, the paste would be solidified by means of heating or cooling to be a sheet with a single layer of uniformly-distributed diamond grits.
  • Said sheet is made of the mixing of metal powder and bond: when the mixing is about to solidify, press the abrasive particles into one surface or double surface of the sheet.
  • Said cutting tool includes multiple sheets, and the distribution pattern of abrasive particles on each layer is the same or different; for example, the outer layer has a higher density of diamond while the inner layer has a lower density and bigger-size diamond.
  • Another art of the present invention is as follows:
  • Said template is a plane template formed by the following steps: after electromagnetic radiating, covering the positions where does not need to adsorb abrasive particles, thus an electromagnetic template is formed.
  • Said template can be a plasma-template.
  • Said template can be an electric template with positive or negative charge.
  • Said sheet is made by the mixing of metal powder and bond compressed in a mold.
  • Said cutting tool is formed by multiple sheets, and the distribution pattern of abrasive particles on each layer is the same as or different; for example, the outer layer has a higher density of diamond while the inner layer has a lower density and bigger-size diamond.
  • the present invention provides a template, the shape and the pattern of the template can be designed conveniently on the arranging requirement of abrasive particles, and the template can adsorb only a single layer of abrasive particles; place the template with uniformly distributed abrasive particles into or adhere to sheet, then a sheet will be formed with uniformly distributed abrasive particles, thus the position of abrasive particles can be located exactly on the sheet on predetermination.
  • the abrasive particles can be uniformly distributed, or arranged on the requirement of accounted cutting force of provided cutting and grinding tools. For example, higher concentration diamond grits are preferred in the edge and front of saw, while in the middle, the lower concentration diamond grits are preferred.
  • the saw blade with uniformly distributed diamond grits has a lower concentration diamond grits, the practical cutting distance is 1150 m (the distance of irregularly distributed diamond saw blade is 450 m), the blade cuts smoothly and there are no collapsed pieces of blade, the sum powder consumption of abrasive tools decreases by 30 percents, the noise of perigee decreases by 10 db (A), cutting efficiency increases by 30 percent, and the useful life is three times longer than those irregularly distributed diamond saw blades.
  • Fig. 1 it shows a perspective view of a segment of diamond tool, indicated with 10.
  • the segment 10 is formed by a plurality of layers, 11, 12, 13 and 14, which are impregnated with abrasive grits, indicated as hexagonal frame 1.
  • the electromagnetic template 20 of the present invention is capable of adsorbing a single layer of abrasive particles (for example, diamond grits) after corona discharging; when the adsorptive points are occupied by the adsorbed diamond grits, the other grits cannot be adsorbed on the same place, so the adsorbed grits form a single layer, and template can be designed on the requirement of the arrangement of diamond or other abrasive particles, thus the diamond, cubic boron nitride grits are uniformly distributed on the template, and the distribution form can be designed freely on the desire of designers.
  • abrasive particles for example, diamond grits
  • Fig. 2 is a view of the distribution of abrasive particles on the template, wherein Fig. 2A shows the oblique distribution of abrasive particles; Fig. 2B shows the forward distribution of abrasive particles; Fig. 2C shows the cross distribution of abrasive particles.
  • the template may be a plane as referred to Fig. 3 ; in addition, a cover 21 is adhered on the template, which covers the positions where it is not necessary to adsorb abrasive particles, when the abrasive particles such as diamond grits are adsorbed on the template: then a uniform distribution of diamond grits on the template is achieved; the advantage of this method is that the template is easily treated with, and the shape of cover is freely and easily treated.
  • the powder can first be mixed with a suitable binder (typically organic) and a solvent that can dissolve the binder.
  • a suitable wetting agent e.g. , phosphate ester
  • the slurry can then be poured onto a tape and pulled underneath a blade or leveling device, then the sheet would be made.
  • the tape casting method is a well known method in rubber and plastic manufacturing. By adjusting the gap between the blade and the tape, then the slurry can be cast into a sheet with the right thickness.
  • a suitable organic plasticiser can also be added to provide the desired characteristics.
  • Typical binders include polyvinyl alcohol (PVA), polyvinyl butyral (PVB), polyethylene glycol (PEG), paraffin, phenolic resin, and acrylic resin.
  • Typical binder solvents include methanol, ethanol, acetone, trichloroethylene, toluene, etc.
  • Typical plasticisers are polyethylene glycol, diethyl oxalate, triethylene glycol dihydroabietate, glycerin, rosin, etc.
  • the organic agents so introduced are used to facilitate the fabrication of metal layers. They must be removed before the consolidation of metal powders. The binder removal process is also well known to those skilled in the art.
  • a template impregnated with diamond or other abrasive particles is laid on the top of the sheet. After the template is properly positioned, press the abrasive particles into the sheet, remove the template, then the abrasive particles are uniformly distributed on the sheet.
  • the depth of the abrasive particles embedded in the sheet can be designed according to requirements, and those skilled in the art will know that the desirable height of the abrasive particles extends outwardly from the sheet.
  • the manufacture of template may be the following: after electromagnetic radiating on a metal template, the template will be provided with adsorbing power, then place a cover (e.g. a cardboard) on the template, covering the positions where it is not necessary to adsorb abrasive particles, thus the template can achieve uniform distribution of abrasive particles.
  • a cover e.g. a cardboard
  • Said template is preferred to be a plasma template, which has a good single layer adsorbing power.
  • Said template is an electric template, which has adsorbing power with negative charge.
  • Fig. 4 shows the sheets of the present invention with uniform distributed abrasive particles assembled transversely; the segment in Fig. 4 is formed of a plurality of transverse sheets 41. Its difference is that the segment is formed transversely, and it requires that the abrasive particles are distributed transversely on the tool, and the template is made according to requirements.
  • the location methods of abrasive particles are several, and the uniform distribution of abrasive particles according to the present invention can be conveniently achieved.
  • a 40/50 U.S. mesh diamond grit (SDA-85, made by DE BEERS company) is provided.
  • the sheet is a mixture of metal powder and acrylic resin. Five different proportions of cobalt and bronze were used for the metal powder.
  • An acrylic binder was added to the mixture and the charge was blended to form a cake.
  • the cake was then rolled between two rollers to form sheets with a thickness of 1 mm; place the template distributed with adsorbed diamond grits on the sheet, press the diamond grit into the sheet, then remove the template.
  • These sheets were cut in the shape of diamond saw segments with a length of 40 mm and width of 15 mm. Three of each of such segments were assembled and placed into a typical graphite mold for making conventional diamond saw segments.
  • the segments were pressed and heated by passing electric current through the graphite mold. After sintering for three minutes, the segments were consolidated to a height of 9 mm with less then 1% porosity. Twenty-four segments for each composition were fabricated, they were laser welded onto a circular saw whose diameter was 14 inches. The performance of these blades is better than those made by conventional methods in sawing the granite.
  • the present invention provided an adsorptive template, the shape and the pattern of the template can be designed conveniently on the arranging requirement of abrasive particles, and the template can adsorb only a single layer of abrasive particles; place the template with uniformly distributed abrasive particles into or adhere it to the sheet, then a sheet with uniformly distributed abrasive particles will be formed, thus the position of abrasive particles can be located exactly on the sheet with determination.
  • the abrasive particles can be uniformly distributed, or arranged on the requirement of accounted cutting force of provided cutting and grinding tools. For example, higher concentration diamond grits are preferred in the edge and front of saw, while in the middle, the lower concentration diamond grits are preferred.
