Granite is a plutonic rock that often forms well-developed mineral grains that can be discerned with the naked eye, hence the name. Granite is not easy to be weathered, beautiful in color, and keeps its appearance for a long time. Due to its high hardness and wear resistance, it is not only used for architectural decoration projects and hall floors, but also for outdoor carvings.

1) Sawing processing is to use a stone sawing machine to saw granite blocks into raw boards (generally with a thickness of 20mm or 10mm), or semi-finished products in the shape of strips and blocks. This process is a rough processing process, which has an impact on the plate rate of blocks, plate quality, and the economic benefits of the enterprise. Commonly used equipment for sawing processing includes frame-type automatic sanding saws for granite; multi-blade two-way cutting machines; multi-blade computer-controlled granite cutting machines and granite disc saws.

2) The purpose of grinding and polishing is to further process the sawn rough board to make its thickness, flatness and gloss meet the requirements. This process needs to be completed through several steps. First, rough grinding and leveling are required, and then semi-fine grinding, fine grinding, fine grinding and polishing are carried out step by step, so that the original color, pattern and luster of the granite can be fully displayed.

Singeing processing, also known as spray-burning processing, uses the difference in thermal expansion coefficient of different mineral particles that make up granite, and sprays and burns with flames to make some particles on the surface thermally expand and loosen, forming an undulating and orderly rough decorative pattern. This rough-faced granite slab is suitable for non-slip floors and exterior wall coverings.
