For purple ceramic parts with hollow inner cavities, paper is filled in the cavity of the purple ceramic part, then plastic paper is used for covering the opening of the cavity, the edge of the plastic paper is sealed at the periphery of the opening of the cavity of the purple ceramic part by sealant, and then the purple ceramic part is polished by a vibration polishing machine.

By adopting the method, the vibration polishing machine can polish a plurality of purple pottery pieces at one time, 5-10 kettles can be polished by one worker in 1 day, and the production efficiency is improved by at least 5 times. In addition, the requirements on the technical ability and experience of workers are not too high, the surface brightness of the polished product is uniform, and the polishing quality is stable. The invention skillfully adopts a method of filling the purple ceramic piece cavity with paper and sealing the cavity, solves the problem that a vibration polishing machine cannot polish the purple ceramic pieces with hollow inner cavities such as pots, bottles and the like, and can prevent the hollow purple ceramic pieces from being damaged by impact and prevent the inner structures of the purple ceramic pieces from being damaged. The invention adopts three times of grinding process and reasonable grinding materials, best simulates the fire skin removing and wire wiping process of the traditional process, and ensures that the purple pottery pieces are better buffered by the porcelain granules when being vibrated and ground in the vibration polisher and cannot mutually impact and interfere. The step-by-step thinned carborundum enables the surface of the purple ceramic piece to be gradually ground to be finer, so that the subsequent polishing effect is better.
