In this embodiment, after the abrasive grains 30 are spread on the alloy sheet 10, the alloy sheet is placed on a plane with the top surface facing upward, the outer circumferential surface of the coated grinding wheel base 40 is in contact with the top surface of the alloy sheet 10, the grinding wheel base 40 is pushed to roll, the alloy sheet 10 is wound and adhered to the outer circumferential surface of the grinding wheel base 40, and the operation of adhering the alloy sheet 10 is completed. In order to further facilitate the work of bonding the alloy sheet 10, a modified example thereof: before the abrasive grains 30 are paved in the step (2), the top surface of the alloy sheet 10 is coated with the diluted glue solution 20, the diluted glue solution 20 is adopted, the viscosity is not too strong, the diamond abrasive grains are paved, the redundant abrasive grains 30 on the top surface of the alloy sheet 10 can be scraped by a scraping blade, the rest abrasive grains 30 are adhered in the concave pits 101 and cannot fall off, when the alloy sheet 10 is adhered, the alloy sheet 10 can be directly wound, and the alloy sheet can be adhered to the outer circular surface of the grinding wheel base body 40, so that the operation is more convenient and rapid. In this embodiment, by manufacturing the alloy sheet 10 with the pits 101, the abrasive grains 30 on the top surface are scraped after the diamond abrasive grains are spread, and the abrasive grains 30 in the pits 101 are left, so that the abrasive grains 30 are rapidly arranged and bonded to the outer circular surface of the grinding wheel base 40, the operation is convenient, and large-scale batch production is facilitated.

In the step (5), the feed speed of the grinding wheel base 40 is increased when the movement of the grinding wheel base 40 is controlled during the welding and the feed from one pocket 101 to the next pocket 101 is performed. The feeding is accelerated to reduce the melting phenomenon of the non-brazing part of the alloy sheet 10, so that the volume of a brazing molten pool is reduced, the random movement of the abrasive particles 30 in the brazing process is further reduced, and the arrangement reliability of the abrasive particles 30 is improved; the feeding speed of the grinding wheel base body 40 comprises a circumferential feeding speed and an axial feeding speed, and the feeding speed is increased at a position without a grinding wheel on the alloy sheet 10 by combining the circumferential feeding speed and the axial feeding speed, so that the reliability is improved, the welding speed is increased, and the welding efficiency is improved.
Second embodiment, referring to fig. 3 and 4, a brazing method for orderly arranging a plurality of layers of diamond grinding wheels comprises the following steps: (1) manufacturing an alloy sheet 10: manufacturing an alloy sheet 10 by using an alloy material, and processing a plurality of pits 101 which are uniformly distributed and are sunken towards the bottom surface of the alloy sheet 10 on the alloy sheet 10; (2) laying abrasive particles 30: coating diluted glue solution 20 on the top surface of the alloy sheet 10, then spreading diamond abrasive particles, and scraping the abrasive particles 30 on the top surface to leave the abrasive particles 30 in the pits 101; (3) alloy powder and filler 50: laying a layer of alloy powder which is not less than the height of the pit 101 and contains the glue solution 20 and is mixed with the filler 50 on the top surface of the alloy sheet 10 to form an alloy composite sheet; (4) gluing the grinding wheel matrix 40: coating a glue solution 20 on the outer circular surface of the grinding wheel matrix 40; (5) bonding the alloy composite sheet: bonding the top surface of one alloy composite sheet formed in the step (4) on the outer circular surface of the grinding wheel base body 40, and bonding the top surface of at least one alloy composite sheet on the outer circular surface of the alloy composite sheet on the grinding wheel base body 40 layer by layer; (6) welding: and (4) brazing the pits 101 of the alloy composite sheets bonded in the step (5) point by point, sintering and accumulating the alloy sheet 10 material and the alloy powder at the brazed positions, and cooling to fix the abrasive particles 30 and the grinding wheel base body 40. In the embodiment, the arrangement mode of the two pairs of abrasive particles 30 is the same as that in the first embodiment, the alloy sheet 10 with the concave 101 is manufactured, so that the abrasive particles 30 on the top surface are scraped after the diamond abrasive particles are spread, the abrasive particles 30 in the concave 101 are left, and the abrasive particles 30 are rapidly arranged. In order to realize the structure of the multi-layer abrasive particles 30, alloy powder and filler 50 are laid on the bottom surface of the alloy sheet 10 to form an alloy composite sheet, and then the alloy composite sheets are bonded layer by layer to form a multi-layer structure. In addition, when the plurality of alloy composite sheets are bonded layer by layer, diamond abrasive particles on each layer of alloy composite sheet form a staggered structure, as shown in fig. 4, so that the welded abrasive particles 30, particularly the abrasive particles 30 on the outer layer, are firmer.
In a further improvement of the second embodiment, the alloy sheet 10 used in the step (1) is an Ag-Cu-Ti alloy sheet 10, which is the same as the first embodiment, and the thickness of the alloy sheet 10 is 0.8-1.2mm, and the Ag-Cu-Ti alloy sheet 10 is used to facilitate subsequent bending and welding. Further, the composition of the alloy powder in the step (3) is the same as that of the alloy sheet 10, and the particle size of the filler is the same as that of the alloy powder. The alloy powder with the same component as the alloy sheet 10 is adopted, so that the alloy powder and the alloy sheet 10 are fused in the subsequent welding process, the uniform mixing of the alloy powder and the filler is facilitated due to the fact that the granularity of the filler is the same as that of the alloy powder, and the consistent performance after mixing is guaranteed. In addition, the filler is alumina ceramic particles. The alumina ceramic particles have high hardness and melting point, and do not melt during welding, so as to support the abrasive particles 30, but other metal or nonmetal particles with high melting point can also be used, so as to support the abrasive particles without being melted during use. In a further improvement, in the same way as in the first embodiment, in order to improve the reliability of the abrasive grains 30 after welding and improve the welding efficiency, in the step (6), the feeding is performed by controlling the movement of the grinding wheel base 40 during welding, and the feeding speed of the grinding wheel base 40 is increased when the grinding wheel base is fed from one pit 101 to the next pit 101. The self-sharpening performance of the grinding wheel is increased by increasing the feed rate of the grinding wheel matrix 40 to reduce the volume of the weld pool and thus reduce weld collapse and form a loose porous abrasive layer.
In the first embodiment and the second embodiment, the electron beam brazing is adopted, and welding can be performed aiming at certain point positions, so that the consolidation strength of the diamond is ensured, the large-area heating of the grinding wheel is avoided, and the processing purposes of small energy input and high processing efficiency are realized. The alloy sheet 10 adopts a mould pressing mode, is simple and easy to implement, has high processing efficiency, saves cost and is suitable for large-scale production. After welding, the alloy sheet material in the pit 101 is melted and accumulated around the abrasive grain 30, and wraps under the abrasive grain 30 to form a hill-like structure to fix the abrasive grain 10, and the pit 101 not only functions to position the abrasive grain 30, but also functions as a brazing filler metal to melt and cool and fix the abrasive grain 30. In both the first embodiment and the second embodiment, the alloy sheets 10 with the pits are adopted, and the traditional mode of directly arranging the alloy sheets on the outer circular surface of the grinding wheel base body is changed into the planar arrangement mode of the alloy sheets 10, so that the arrangement difficulty is greatly reduced, and the arrangement efficiency is improved; in addition, because the alloy sheet 10 with the pits is adopted, the alloy sheet is used for brazing besides being used for arranging the abrasive particles 30, other brazing filler metals are not needed to be added to the single-layer diamond grinding wheel, the production process is simplified, and meanwhile, the alloy sheet 10 can be formed at one time by adopting stamping or forging, so that the processing efficiency is improved; for the multilayer diamond grinding wheel, the added alloy powder and the filler 50 are also used as brazing filler metal together with the alloy sheet 10, other brazing filler metals do not need to be added specially, the production process is simple, and the multilayer diamond grinding wheel is suitable for large-scale mass production.
