Embodiment Construction

[0027] see figure 1 , shows a soft abrasive polishing disc of the present invention.

[0028] The soft abrasive polishing disc 1 has a disc structure with a through hole in the middle, which can be fixed to the grinding tool by a fixing device. The soft abrasive polishing disc 1 is used to process workpieces with high surface precision requirements such as silicon discs.

[0029] see figure 2 , shows a schematic structural view of an embodiment of the soft abrasive polishing disc of the present invention.

[0030] The soft grinding and polishing disc 1 at least includes a grinding layer 11. Through comparative analysis, the grinding layer 11 is made of a material selected from soft metals. Because soft metals are soft, when the workpiece is polished, the final polishing In the process, high-precision polishing of the surface can be achieved.

[0031] Optionally, through selection, it is found that tin, as a material in soft metals, has the advantages of good ductility and ...

Abstract

A soft grinding and polishing disc is in a round disc structure. A through hole is formed in the middle of the soft grinding and polishing disc. The soft grinding and polishing disc at least comprises a grinding layer which is formed by tin-lead alloy; the tin-lead alloy is formed by, by mass percent, 65 to 75 percent of tin and 25 to 35 percent of lead; an intensified layer is arranged on the rear of the grinding layer; the intensified layer is formed by materials with intensity and melting point higher than the grinding layer. The soft grinding and polishing layer has the advantages of being simple in structure and capable of overcoming the deformation problem during the grinding, meanwhile avoiding the scrap adhering problem during the grinding, improving the machining accuracy and the efficiency and being practical.

Description

technical field [0001] The invention relates to the accessory technology of a grinding machine, in particular to a soft grinding and polishing disc which can effectively improve efficiency and prolong service life. Background technique [0002] In the past, the grinding disc is an important grinding tool used on the grinding machine mainly made of abrasive materials. The performance of the grinding disc directly affects the performance of the entire grinding process and the precision of the finished product. Therefore, the grinding disc is an important tool for grinding machines. an important factor in performance. There are many types of grinding discs, and there are various shapes and sizes. Through different choices of materials, bonding agents and processes for making grinding discs, different working performances can be achieved. Each grinding disc has a certain scope of application according to its own characteristics. Therefore, when grinding, the appropriate grindin...
