Polishing method for tiny ceramic product

Abstract

The invention provides a polishing method for a tiny ceramic product. The polishing method includes the step that by means of a rolling polishing machine and a polishing solution, a cambered surface and a straight body position of the tiny ceramic product are polished simultaneously. The polishing method concretely includes the steps that firstly, the polishing solution is prepared, secondly, multiple blocks of the tiny ceramic products and the polishing solution are placed in the rolling polishing machine, the rotational speed of the rolling polishing machine is controlled ranging from 10 rpm to 60 rpm, and the polishing time is controlled ranging from 2 hours to 60 hours; with the actions of mechanical friction and chemical etching, polished tiny ceramic products are obtained in the rolling polishing machine; the polishing solution comprises, by mass, ceramic polishing powder, high-frequency porcelain and water at the ratio of 1: 50-200 :20-120, the ceramic polishing powder comprises SiO [2] particles with an average diameter ranging from 20 nm to 300 nm and cylinder-shaped Al [2]O [3] with a diameter ranging from 1 mm to 10 mm and a height ranging from 2 mm to 20 mm. The one-time yield of obtained tiny ceramic products is larger than 95 %, the surface roughness of the obtained tiny ceramic products is smaller than 5 nm, forty thousand tiny ceramic products can be processed simultaneously at one time, the processing time is shortened, and the production cost is saved.

Description

technical field [0001] The invention belongs to the field of ceramic product processing, and in particular relates to a method for simultaneously polishing the curved surface and the straight body of a tiny ceramic product. Background technique [0002] Ceramics have good wear resistance, and the hardness is second only to diamond, reaching Mohs 9. At the same time, the compactness of ceramics makes it stronger than tempered glass. The above two characteristics are very suitable for high-end watches, mobile phones and other electronic products. button etc. Therefore, the use of more environmentally friendly ceramics to replace traditional plastic and tempered glass materials as the buttons of electronic products has gradually changed from concept to reality. [0003] Because of the tiny size of the ceramic products, ordinary polishing technology (polishing ceramic products side by side on a polishing machine) is difficult and the production capacity is low, such as a watch ...

Problems solved by technology

[0003] Because of the tiny size of the ceramic products, ordinary polishing technology (polishing ceramic products side by side on a polishing machine) is difficult and the production capacity is low, such as a watch button with a diameter of 3-8mm and a thickness of 0.3-1.0mm (its volume is 2.1-50.3 mm 3 ), there is no record in the prior art how to obtain high-smooth tiny ceramic products in batches
