Sizes and specific role of garnet sand used in stone cutting
I. Recommended garnet sizes and applicable scenarios
60 mesh (about 0.25mm)
Applicable: Cutting hard or thick stones (such as marble, granite).
Features: Coarser particles, high cutting efficiency, suitable for fast splitting of hard materials.
80 mesh (about 0.2mm)
Applicable: Conventional cutting of ordinary stones (such as rock slabs, ceramics, thin stone).
Features: Balance cutting efficiency and surface finish, with a wide range of applications.
100 mesh (about 0.15mm) or 120 mesh (about 0.125mm)
Applicable: Thin stone or occasions requiring high-precision cutting (such as mosaics, special-shaped processing).
Features: Finer particles, smoother cutting surface, but relatively slow cutting speed.
2. The specific role of garnet sand in stone cutting
Improve cutting efficiency
The Mohs hardness of garnet sand reaches 7.5-8.0. Combined with the impact force of high-pressure water flow, it can quickly penetrate hard materials such as stone and significantly improve the cutting speed.
The uniform particle distribution and self-sharpening property enable it to maintain a sharp edge during the cutting process, reduce abrasive loss, and maintain stable cutting efficiency.
Ensure cutting quality
Almost no heat is generated during the cutting process, avoiding deformation or edge collapse of the stone due to high temperature, ensuring a smooth cutting surface, and reducing the need for subsequent processing.
High-hardness particles can accurately control the cutting trajectory, which is suitable for complex shape processing (such as parquet) and improves the precision of the finished product.
Applicability and economy
It can cut a variety of stones such as granite, marble, and rock slabs, especially suitable for high-precision architectural decoration fields.
Garnet sand can still be reused after crushing, combined with low dust characteristics, to reduce material costs and environmental pressure. Extend equipment life
The hardness and structural characteristics of the particles reduce the wear on the water jet equipment, reduce the risk of knife blockage, and extend the service life of the equipment.
In summary, garnet sand has become a core material that takes into account efficiency, quality and economy in stone cutting due to its hardness, self-sharpening and environmental protection characteristics.
