Embodiment Construction
[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. Apparently, the described embodiments are some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention belong to the protection scope of the present invention.
[0033] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a grinding wheel in the prior art. Such as figure 1 As shown, the grinding wheel in the prior art includes platform metal 11 and grinding teeth 12, wherein, the mounting surface of platform metal 11 has offered several grooves, and the shape of groove is consistent with the shape of grinding teeth 12, so t...

The invention provides a grinding wheel, comprising: an annular base body; at least two rings of grinding wheel teeth located on one end surface of the annular base body, the bottom ends of the grinding wheel teeth are fixedly connected to the annular base body through an adhesive, and the bottom ends of the grinding wheel teeth located on the outer ring The grinding wheel teeth are provided with drain holes running through the bottom end and the top end thereof, and the drain holes communicate with the drain channels in the annular base. According to the grinding wheel of the embodiment of the present invention, by directly fixing the grinding wheel teeth on the end surface of the annular base, there is no need to open grooves on the end surface of the annular base, thereby avoiding the occurrence of the unusable part of the grinding wheel teeth embedded in the groove, and improving the The utilization rate of the grinding wheel teeth reduces the production and processing cost; moreover, due to the drainage holes in some grinding wheel teeth, the cooling effect of the end surface of the annular base is enhanced, so that the cooling requirements can also be met when two or more rings of grinding wheel teeth are set.
Description
technical field [0001] The invention relates to the technical field of silicon wafer processing, in particular to a grinding wheel. Background technique [0002] At present, the grinding wheel is widely used in the grinding process and thinning process of silicon wafer forming. It is mainly composed of metal plate and grinding teeth. 4mm, 5mm and 7mm, because the grinding teeth are partially embedded in the grooves, the depth of the grooves is usually 1mm, which will lead to a reduction in the height of the final practical part of the grinding teeth. In the grinding process of silicon wafers, the grinding wheel is the main consumable, which is mainly reflected in the wear and tear of the grinding teeth, but the grinding teeth are expensive and the cost is high, which will lead to an increase in the processing cost of the silicon wafer. In addition, the existing grinding wheel is limited by its cooling and chip removal capabilities, and the grinding teeth on it usually have ...
