The invention provides a manufacturing method for a polished ceramic chip. The manufacturing method comprises the following steps: (1) performing ball-milling on raw materials and auxiliary materials for producing a green brick, spraying, granulating, pressing to form the green brick, and firing the green brick in a kiln to prepare an unglazed green brick; (2) applying ground glaze on the unglazed green brick, and spraying impervious glaze on the unglazed green brick; (3) after a glaze surface is dried, washing edges; (4) printing, spraying transparent glaze, firing in glost kiln to obtain a semi-finished product; (5) placing the semi-finished product on a polishing line, and polishing and waxing by adopting an elastic polishing process, grinding edges after polishing, and packaging to obtain the polished ceramic chip. According to the method, the problems of glaze spraying pin holes, ceramic chip water permeation, miss polishing or over polishing, polishing breakage and the like in the production process of the polished ceramic chip are solved; the quality of the polished ceramic chip is greatly improved.
