The present invention relates to a mosaic tile manufacturing process, and in particular, by forming a mosaic groove in the tile itself to form a mosaic tile before the final firing process of the tile, the productivity of the mosaic groove can be easily increased as productivity can be increased. In the mosaic tile manufacturing process, it is possible to automatically process square grooves with a fixed diamond knife by continuously switching in a linear direction and a perpendicular direction when the tile is moved on a conveyor. It is about.

In general, tiles are very thin compared to the surface area, and are fired at temperatures above red during the manufacturing process with oil or oil so that they have special physical properties and characteristics.

Tiles include interior tiles, exterior tiles, mosaic tiles, acid resistant tiles, floor tiles, salted tiles and query tiles.

Originally, a tile means a board-like material covering a floor, a wall, a roof, etc., but it is mainly used in a floor, a wall, and the like in Korea.

In addition, tiles have various performances, and are relatively simple to construct, and rarely cause cracking or discoloration after construction, and are particularly durable, and thus are the best material for covering and protecting the surface of the structure.

Tile is a material used for surface decoration as an exterior or interior material, so the color or shape of the surface should be beautiful.

In particular, the conventional mosaic tile was molded by sintering a tile of a certain size and then digging a square groove and filling the groove with cement or mortar.

In this case, the mosaic tile is divided into a case of forming a tile by scratching the groove at the time of a mold at the first predetermined size, and a case of processing the groove on the calcined tile.

In addition, the mosaic tile is divided into a primary fired product attached to a floor or the like and a secondary fired product attached to a wall or the like.

The process of removing the filled glaze is performed.

The mosaic tile is paved or attached to the floor, and then filled with the mortar or cement in the groove is good aesthetics.

The mosaic tile in the case of forming a groove in a tile formed as a primary firing product is a step of forming a square groove after forming a tile of a predetermined size, applying a glaze to the surface in a dry state, and then performing a firing treatment. In addition to performing a series of processes to carry out the mortar or cement in the grooves during construction, such as to enhance the aesthetics.
