Polishing process and device for 3D arc surface of ceramic member

Abstract

Disclosed is a polishing process and device for a 3D arc surface of a ceramic member. The polishing process includes: A, clamping a product needing arc surface polishing by a clamp, enabling a to-be-polished face of the product to be exposed outside, and mounting a polishing belt on a machine capable of adjusting horizontal and vertical positions of the belt; B, adjusting positions of the polishing belt and the to-be-polished face of the product to enable the polishing belt to compress the to-be-polished face of the product and to completely contact with an arc surface of the to-be-polished face of the product; C, spraying a polishing liquid into a contact face of the product and the polishing belt, and controlling the polishing belt to rotate to polish the to-be-polished face of the product. The device comprises the clamp and the polishing belt. By using the polishing process and device, processing requirements on surface coarseness of ceramic structural member polishing can be met, over-polishing of holes in the arc surface is avoided, the process is simple, defects like grinding wheel lines and tool marks on the arc surface can be well removed, processing yield can be increased effectively, and production cost can be saved.

Description

technical field

[0001] The invention relates to a polishing process and a device of a 3D arc surface of a ceramic piece. Background technique

[0002] Ceramic is a multi-functional oxide crystal that integrates excellent physical and chemical properties. Its hardness is second only to diamond and reaches Mohs level 9. At the same time, the compactness of ceramics makes it have a large surface tension. The above characteristics are very suitable for mobile phones. , watches, cameras and other electronic product structural parts.

[0003] In order to meet the requirements of the development of ceramic optical devices and obtain a surface with high flatness and high brightness, chemical mechanical polishing of ceramics must be carried out to reduce or eliminate the scratches on ceramic panels in the process of ceramic cutting and grinding, and obtain high flatness. , High brightness products.

[0004] At present, conventional plane polishing or special-shaped polishing proces...
