Embodiment 1

[0034] Embodiment 1: The grinding and polishing process of the present invention is adopted, and the specific data are shown in Table 3.

[0035] The mirror-polished parts of the complex surface of structural porcelain are: high-performance 99 alumina ceramic guide discs for high-speed chemical fiber texturing machines, and the arc surface on the circumference requires mirror processing (see figure 1 ).

[0036] See the content of the invention for the carrying tool and diamond abrasive used. The outer dimension of the pre-processed guide disc is φ52 +0.022 , roughness Ra0.2-0.3, polished by three processes (Table 3):

[0038]

Embodiment 2

[0039] Embodiment 2 (comparative example): traditional polishing process, concrete data see (table 4)

[0040] Using the existing traditional polishing method, diamond micropowder abrasives of different particle sizes are applied to the white canvas for four-step polishing, which requires mirror surface. The processed parts are the same as in Example 1, the outer garden of the pre-processed guide plate is φ52 +0.01 Roughness Ra0.2~0.3.

[0043]

Embodiment 3

[0044] Embodiment 3 (comparative example): the specific data is shown in Table (5), the carrying tool adopts self-made boron carbide emery cloth, and the diamond abrasive adopts a processing method that changes step by step from coarse to fine. The parts to be processed are the same as in Example 1, the outer circle of the pre-loaded guide plate is Φ52+0.02 and the roughness is Ra0.2-0.3.

Abstract

The invention belongs to the field of precision finishing of structural or functional ceramic, particularly relating to a mirror polishing method for a complex ceramic surface. The method comprises the following steps of: adhering a grinding agent to abrasive cloth or abrasive paper and performing a plurality of polishing processes on the mirror surface from coarse to fine to improve degree of finish step by step. The method is characterized in that: the grinding agents adopted in the processes are micron-sized grinding agents with same granularity; and the abrasive cloth adopted in the polishing processes gradually changes from coarse to fine according to the granularity.

Description

technical field [0001] The invention belongs to the field of precision machining of structural or functional ceramics, in particular to a mirror polishing method for complex ceramic surfaces. Background technique [0002] High-performance structural ceramics are increasingly used in precision wear-resistant mechanical parts, such as ceramic valves, ceramic rolls, seals, bearings, wire drawing touches, yarn guides for textile machinery, femoral joints and seats, etc., on which The opposite grinding surface often requires high-precision and high-gloss mirror processing. [0003] For structural or functional ceramic parts, if it is required to polish the flat mirror surface, it is not difficult to use precise single-side and double-side grinding and polishing machines for different processing materials, and to select suitable grinding materials and processes to achieve mirror surface processing. For curved surfaces, especially complex curved surfaces, generally only finishing ...
