Polishing disk for quickly polishing surface of flaky diamond crystal and polishing method of polishing disk

Abstract

The invention relates to a polishing disk for quickly polishing the surface of a flaky diamond crystal and a polishing method of the polishing disk. The polishing disk comprises a grinding body manufactured by the method comprising the steps that diamond micro powder and synthetic resin are mixed according to a ratio, an adhesive is added, and drying is performed after shaping; the grinding body is divided into a coarse polishing disc, a medium polishing disc and a fine polishing disc according to the granularity of the diamond micro powder; according to the polishing method, the coarse polishing disc, the medium polishing disc and the fine polishing disc are sequentially used for polishing the surface of the diamond crystal, and water flow is added for washing and cooling in the polishing process. The diamond micro powder with various particle size grades is used, the polishing efficiency can be obviously improved, elasticity is improved through materials such as synthetic resin and the like, damage such as crystal breakage and the like caused by unevenness of the surface of the diamond crystal in the polishing process is avoided, generated abrasion dust is taken away through the water flow in the polishing process, the crystal surface can be cooled, and the crystal quality is effectively protected.

Description

technical field [0001] The invention relates to a polishing disc for quickly polishing the surfaces of flaky diamond single crystal crystals and flaky diamond polycrystalline crystals, aiming at improving the surface polishing efficiency of single crystal diamond flaky crystals and polycrystalline diamond flaky crystals; The technical field of diamond crystal surface polishing. Background technique [0002] In the 21st century, due to its excellent physical and chemical properties, diamond crystals have attracted worldwide attention for their application prospects in high-tech fields. Among them, single crystal diamond flake crystals and polycrystalline diamond flake Windows, electronic devices, heat-conducting substrates and other fields have a wide range of application prospects and research and development directions. [0003] In order to make full use of diamond materials, it is very important to polish them to make their surface roughness meet the requirements of use. ...

AI Technical Summary

Problems solved by technology

[0006] The existing single crystal diamond crystal polishing equipment uses a cast iron polishing disc, using a mechanical polishing method and a catalyzed electrochemical method produced by friction between the diamond crystal and the cast iron disc surface. The removal rate is slow and the heat generation is serious, which affects the efficiency of single crystal diamond crystal polishing. , at the same time, due to the high hardness of the cast iron disc, it will cause damage such as fracture of the diamond flake crystal

In addition, due to the thin thickness of the polycrystalline diamond flake crystal, the polishing efficiency of the existing equipment is low when polishing the surface of the polycrystalline diamond flake crystal, and it is easy to cause damage such as crystal fracture.

[0007] To sum up, on the one hand, diamond has extremely high hardness and excellent chemical stability, and it is quite difficult to process it.

On the other hand, the existing methods cannot solve the polishing problem of diamond, and there is no polishing method for large-sized single crystal diamond
