Description

Stone Bidirectional Grinding Apparatus "

The present invention relates to a stone bi-directional machining apparatus, and more particularly, to a stone bi-directional machining apparatus which polishes or abrades a stone edge portion through a grinding module disposed symmetrically when cutting and polishing margins of a supplied stone .

In general, a conventional stone cutting machine has a two-step process system in which a product is set in a longitudinal direction using mainly a ruler to set a manual or semi-automatic setting, and the product is laterally cut using a ruler.

In order to overcome the above problems, an orthogonal type stone cutting machine has been developed. In the conventional orthogonal type stone cutting machine, a monorail is installed in two frames formed in a shape, and a terminator is mounted on a monorail, While the roller carriage is mounted on the transverse rail and moves along the transverse rail so that the roller carriage moves in the lateral direction along the transverse rail, And the slab material disposed is cut by a transverse section.

On the other hand, in the case of performing the abrasive processing on the stone, the surface of the building stone such as marble or granite is polished by using a grinding machine equipped with a grinding stone.

In the polishing step, a step consisting of several steps is required. In the case of polishing one stone cut to a predetermined standard, a rough polishing plate having a high surface roughness is first used, and then an abrasive plate having a gradually lower roughness is successively used The surface of the stone is polished in order to finish it.

As described above, in the conventional grinding machine used for polishing the stone, the drive shaft on which one abrasive plate is mounted is rotated by a motor and the drive shaft is lowered by pressing a manual handle installed on one side of the drive shaft so that the abrasive plate, The surface of the stone is polished by being brought into contact with the upper surface of the stone loaded on the bed.

As a conventional document that discloses the cutting and grinding of the stone described above, reference can be made to Japanese Patent Application Laid-Open No. 10-2014-0075564 (June 19, 2014). In this document, The present invention relates to a stone edge machining apparatus which improves productivity by performing a batch machining operation of cutting in a lateral direction and an oblique direction and polishing in a curved surface. However, in a system for stably cutting and polishing both side edges of a supplied stone There is a limitation that it is not separately disclosed.
