Hard Stone Cutting Technology Details: Mohs Hardness and Diamond Saw Blade Selection Guide

Hard Stone Cutting Technology Explained: A Guide to Mohs Hardness and Diamond Saw Blade Selection

When it comes to the precision cutting of high - hardness stones such as marble and granite, the scientific selection of diamond saw blades has become a key factor that affects cutting efficiency and the quality of finished products. This article delves into the impact of Mohs hardness and crystal particle characteristics on saw blade performance.

First, let's understand the relationship between the physical properties of hard stones and saw blade adaptation. The Mohs hardness scale is a crucial reference. For example, marble typically has a Mohs hardness of 3 - 4, while granite has a hardness of 6 - 7. Different hardness levels require different diamond saw blade configurations. "The higher the Mohs hardness of the stone, the higher the diamond concentration and the harder the matrix of the saw blade should be," says an industry expert.

Specific Requirements for Diamond Concentration, Matrix Hardness, and Tooth Shape Design

Different stone materials have specific requirements for diamond concentration, matrix hardness, and tooth shape design. For softer stones like marble, a relatively lower diamond concentration can be used, usually around 20% - 30%. The matrix can also be relatively softer to ensure a smooth cutting process and reduce the risk of chipping. In contrast, for granite, a diamond concentration of 35% - 45% is recommended, along with a harder matrix to withstand the high wear during cutting.

The tooth shape design also plays an important role. For fine - grained stones, a continuous - rim tooth design is often preferred as it can provide a smooth and precise cut. For coarse - grained stones, a segmented - rim tooth design can improve cutting efficiency by providing better chip removal.

Case Studies in Industrial Scenarios

Let's look at some real - world industrial scenarios. In the tile processing industry, the problem of tile chipping is a common headache. A tile with a Mohs hardness of about 5 - 6 requires a saw blade with a proper diamond concentration and tooth shape. By using a saw blade with a medium - high diamond concentration (around 30% - 35%) and a segmented - rim tooth design, the chipping rate can be reduced from about 15% to less than 5%.

On the other hand, when cutting granite, the risk of sintering is a major concern. A saw blade with an appropriate matrix hardness and a well - designed heat - dissipation structure is essential. For example, by using a saw blade with a hard matrix and an enhanced heat - dissipation structure, the sintering risk can be reduced by up to 80%.

The Key Role of Shock - Absorption and Heat - Dissipation Structures

In heavy - duty cutting operations, shock - absorption and heat - dissipation structures are crucial. A well - designed shock - absorption structure can reduce vibration during cutting, which not only improves the cutting accuracy but also extends the service life of the saw blade. For example, a saw blade with a good shock - absorption design can increase the service life by about 20% - 30%.

Heat dissipation is another important factor. High - temperature generated during cutting can damage the diamond particles and the matrix. A saw blade with an enhanced heat - dissipation structure can effectively reduce the cutting temperature, ensuring stable performance during long - time cutting operations.
