Description of Invention (9) on body 60. According to the present invention, the side of the cover away from the carrier is provided with a fixed dress such as an adhesive coating 100, and particles will adhere to it. In addition, the cover may be made of a substance with adhesion properties, or under the influence of light or temperature, for example. It becomes sticky so that the particles can stick directly to it. However, any means that can hold the particles on the outer surface of the leather, so that the particles adhere to the cover is acceptable. The carrier can be any type of substrate that can support and / or temporarily hold multiple hard particles. As detailed later, the carrier may be a plate (such as metal), a metal foil, a screen type material (such as a wire mesh or a non-wire honeycomb-like material) or a preform of a sinterable material, which forms part of the abrasive material, or the carrier It may be a substrate that is removed by an abrasive material after formation. Fig. 4 shows that a plurality of hard particles 70 are applied to the top surface of the cover 50 and the carrier 60, and thus cover the cover and the carrier surface. Part of the hard particles 75 will pass through the opening 55 of the cover 50 and stop at Zai Zhao, and part of the hard The particles will advance to the carrying surface 57 of the cover, where they will be held in place by an adhesive knot 100.

B7____ Figure 7 shows another view after removing all hard particles not lost by the carrier or cover, only single layer The hard particles 80 and the single-layer particles 75 remain fixed on the cover 50 and the carrier 60, and are directly fixed or fixed through the adhesive substances 90 and 100. It must be understood that 'depending on the average size of the hard particles and the dimensions of the opening 55 and the thickness 110 of the cover 50, the hard particles 75 may be arranged in a pile or column inside the opening 55, as shown in FIG. 6; The single layer shown in the figure; or there may be only a single particle in each opening 55, as shown in FIG. Figure 8 shows the adhesive layer 90. It must be understood that this layer 90 may be a separate component or part of the cover 50 or the carrier 60 or attached / adhered to the cover 50 or the carrier 60. The inner surface of the cover is also provided with a fixing device, and the adjacent surface of the carrier will be adhered to the fixing device. In this case, the fixing device must prevent the cover and / or the substrate from tearing or breaking during the process of separating the cover from the substrate. Such fixtures are, for example, low tack (such as pressure sensitive adhesives) and extraction / release actions, such as extraction through holes or openings or channels in a substrate or carrier. According to the present invention, after the particles are applied to the carrier and the cover and if there is any need to remove any excess or unfixed particles, the cover containing the particles 80 adhered to it is separated from the carrier, leaving the particles 75 on the carrier 60. FIG. 9 schematically illustrates the process of separating the cover 50 and the carrier 60 from each other. During the separation process and after the separation, the cover 50 preferably holds all but at least most of the hard particles 80, and the carrier 60 holds the hard particles 75. In particular, as shown in FIG. 9, the cover 50 can be separated by the carrier 60, removed by the carrier 60, and wound into a roll. It is important to understand that the separation process can be continuous or discontinuous or discrete or batch. In order to assist the separation of the cover 50 and the carrier 60, if the adhesive substance 90 is used, the description of the invention (1 ()) This paper size applies the Chinese National Standard (CNS) A4 specification (2〗 〇χ297 mm) • II-- --- —----- ^ 14 · — 1 (Please read the notes on the back before filling in this page) Order ·---- line. 13 46,809 Printed by the Consumers ’Cooperative of the Ministry of Economic Affairs Β7 ^ The invention description (U) must not be difficult to separate the two from each other. In most of such cases, the substance 90 must be sufficiently adhered, so the particles 75 will adhere to it, but the adhesion is not strong enough to make it difficult to separate the cover 50 from the carrier. According to the present invention, after separating the cover from the carrier, the particles 75 remaining on the plant are in contact with or at least partially surrounded by the holding matrix material. As shown in Fig. 9A ', for example, the powdery sinterable base material 76 is then heated to a molten or sintered material to maintain the particles 75 in a desired pattern, thereby forming an abrasive material. The carrier can form part of the abrasive material, or the carrier can be removed after sintering. In addition, the preform of the sinterable base material can be used in addition to or instead of the base material 76 or other retention type materials on one or both sides of the structure . Section 9B 囷 illustrates that the preforms 77 and 78 of the sinterable material are applied to both sides of the assembly of FIG. 9A, and then the plates 79 are pressed to the assembly, and the abrasive material is sintered by heating. The base material 76 may be deleted 'or may be a powdery sinterable base material or a soluble material. If the material 76 is a fusible material, it will be melted at the final temperature of the preform to be sintered or below, to assist the adhesion of the particles, and to provide the holding matrix by the preform. In addition, the carrier 60 may be a preform of a sinterable material, and the material itself forms a holding matrix 'to hold the particles 75 during the aforementioned manufacturing process of the abrasive material. After the cover is removed and before heating, the further processing of the carrier 60 and the hard particles 75 includes using a pair of opposing compression devices such as the rollers 130 and 140 shown in FIG. 10 to press the particles into the carrier, especially for the carrier 60. This is especially true when the preform of the sinterable base material is pressed tightly to press the hard particles 75 into the carrier 60 and deform the carrier. The original thickness of the carrier 60 is suitable for certain tight paper sizes. The Chinese National Standard (CNS) A4 specification (210x297 mm) is applicable.

Description of the invention (12) Change the thickness of the result under pressure or deformation conditions 120 series is less than the original thickness of 110 ° the width of the carrier 60 (not shown in the figure) can also be changed under such compaction conditions. During compaction, the hard particles 75 can be at least partially or completely embedded in the carrier 60. The final product Different applications require convex portions of different heights β. In one embodiment of the present invention, the 'single-layer surface grinding tool can be manufactured, and hard micro-grains must be raised on the surface 150 of the carrier 60, as shown in FIG. 60. Depending on the depth of penetration of the hard particles 75 and the hard particles 75 into the carrier 60, the hard particles 75 can rest comfortably in the socket 155 and thus anchored to the carrier. Other applications preferably require the hard particles 75 to be completely convex Enter the carrier / preform 60 internally. Refer to sections 6 and 8. And related descriptions and considerations. If the sticky substance 90 exists in the socket 55 due to the result of the magical force / compacting, the sticky substance can be combined with any process such as heating, burning, extraction, vacuum, or dissolution. Substances present on the carrier are removed. The β-removal substance 90 (if present) is an important manufacturing step. It reduces organic matter, water, and gas formation during heating. In particular, it provides a clean manufacturing environment, and hard particles are compatible with Good maintenance between any persistent holding materials. It is particularly important that the sintering 'brazing, fusion, electrodeposition, and thermosetting' all utilize or not utilize negative pressure (vacuum) and / or a protective and / or reducing atmosphere. Figure 12, after the compression / compacting particles 75 enter the interior of the carrier 60, the supplementary retention material 125 can be applied to the hard particles 75 and the carrier which is optionally at least partially applied. The reason why this material 125 is called "supplementary" The carrier 60 itself can also provide a holding matrix for the hard particles, especially if ---- 1 -------- installation ---- order ------- I-line (please read the note on the back first) Matters refill this )

The invention description (13) is especially true when it is a sinterable matrix material. After proper processing, replenishment of the retention material will assist in the permanent bonding of the hard particles 75 to the carrier 60. If the carrier 60 is not a sinterable material, but instead is, for example, a metal foil or a plate or a screen-type material ', then the "supplementary" material 25 is merely a material that provides the integrity of the hard particles and the carrier 60. In this case, the "supplementary" material 125 can be defined as a true brazing material according to the definition of brazing processing function; the components are integrated together through the liquid and then the brazing material is solidified. So in this example, the steel welding material is melted under heat (with load and / or pressure applied or not), and then solidified during the manufacturing process of the grinding material (with load and / or pressure or not). If the brazing material is a combination (mixed or applied to it) of non-brazing type sinterable material ', the brazing material that melts at an appropriate temperature can join the inside (capillary channel) of the non-brazing type sinterable material. The supplementary retention material may be in the form of powder, cut, fiber, paste, slurry, tape, flake, chopped, or crushed solid material block, cold compressed powder, molten metal material ', preferably in the form of an atomized material and an electrolytic solution. It can be metallic materials (such as metal powders and alloy powders and mixtures) or non-metallic materials (such as thermoplastic materials, resins, epoxy resins). The retention material may be selected from pre-sintered or fully sintered powdery materials, wash-bonded powdery tapes, compressive powdered thin tapes or sheets ' including honeycomb-shaped materials and metal-based screen materials. It should be noted that if the 'cover 50 is not removed by the carrier 60 when the supplementary retention material is applied, the supplementary retention material 80 may also assist in holding the particles 80 in the mask and assist the particles 80, and then be removed together with the mask. It should also be noted that if the hard particle ribs include any retained material, the retained material must also be separated by the hard particles in order to allow it to be recovered with the cover removed for future use.

Having said that, in some cases, the removed hard particles can be returned for reuse, even if there is a trace amount of retained material. Pressing the carrier 60 and the hard particles 75 into the carrier, as shown in Figs. 9B and 10 ', may be performed before removing the cover 50, as shown in Fig. 13. It is preferable that the thickness of the cover 50 is thin at this time, or is deformable or elastic or resilient. Under the action of a pressing device such as a plate or a stick 130-1 and 140-1, the cover 50 is compressed, the hard particles 80 are at least partially pressed into the inside of the cover, and the hard particles 75 are also pressed into the carrier 60. After the cover 50 is removed, the resulting material is similar to that shown in FIG. It must be understood that roller compression is only one of many possible options for pressing the carrier 60 and / or hard particles 75 into the interior of the carrier (the pressing device may be flat, wave-shaped, rectangular, circular, etc.).

The figure shows a carrier 650 'honeycomb carrier-cover 68o, a distribution cover 70o, and hard particles 770 in the opening of the honeycomb carrier cover and two opposite load elements 760 and 740. The load is provided with the pressure facing the elements 650, 680 and 700 and the pressure is controlled to maintain the elements together. The load can be generated by the weight of the load element 'or by an additional weight load or mechanical force 800, such as the application to a C-shaped clamp element Β, pressure, magnetic field, etc. It can be understood that this method of holding the carrier and the cover together can provide easy separation of the two and remove hard particles that do not form part of the final grinding to the quality. This clamping is easily carried out using semi-automatic or fully automatic (for example, robotic) machines. After removing the cover 700 and the carrier-cover 680 ', if necessary, the structure shown in FIG. 21 is obtained, including the carrier 650 with the hard particles 700 dispersed thereon and also being compressed into the carrier. For the purpose of the present invention, "sintering", "sintering", "sintering under pressure or heating and pressing", "sintering in solid state", "sintering in liquid state", "liquid sintering", "partial sintering", "Infiltration sintering", "brazing", "fusion", "deposition", "thermoset", "thermal spray", "electrodeposition", "electroplating" and their synonyms and substitutions mean the same; in other words The ingredients are tightly combined with useful abrasive materials and / or tools, and provide permanent retention of the hard particles (experience the life of the hard particles on the abrasive article) on the abrasive article without the need for a carrier or abrasive tool. If the carrier is a metal foil or plate or a completely sintered material or a solid metal tool (such as steel), when the appropriate heating and / or pressure and / or atmosphere is applied to the carrier and the retained material, the material is sintered or melted, It also plays the role of brazing or fusion material, permanently fixing or attaching hard particles in the carrier or the carrier.

When an appropriate amount of heat and / or pressure and / or atmosphere is applied to both the carrier and the supplemental retention material, such supplemental retention material melts and penetrates into the interior of the carrier. This kind of material penetrates into the basic retention material and pores in a liquid phase, and some processes (such as diffusion, decomposition, reduction, 氡Therefore, during the infiltration process, supplementary retention materials were modified to modify the basic retention materials. At the same time, this material and / or its components fixed the hard particles to itself and to the basic retention materials. As a result, the hard particles are held by the combination of the sintered carrier and the supplementary retention material. This process can be referred to as "sintering with infiltration" or "impregnation" or "sintering with fusion". When the mold is heated and pressure is applied to the carrier to assemble the hard particles and / or the retention material or the various components of the retention material, this process is called "pressure sintering" with or without a liquid phase. The generation of the liquid phase is determined by the carrier (it can be the retention material and the composition and combination of the retention material and its various components. In order to provide the most powerful and reliable integration and bonding of hard particles, the retention or retention matrix material is a sinterable matrix Material, which is sintered under pressure in a mold with or without a protective and / or negative pressure atmosphere.
