Are you struggling with low cutting efficiency when dealing with hard stones? The key might be the wrong choice of diamond saw blades! This article delves deep into the physical characteristics of high - hardness materials such as marble and granite and the matching logic of saw blades. From diamond concentration, matrix hardness to tooth shape design, it will teach you how to select saw blades scientifically to enhance cutting accuracy and lifespan.
Hard stones like marble and granite have different physical properties. Marble generally has a Mohs hardness ranging from 3 to 5, while granite has a Mohs hardness between 6 and 7. The size of crystal particles also varies. These characteristics determine the performance requirements of saw blades. For example, stones with larger crystal particles may require saw blades with a more robust cutting edge to prevent chipping.
"Selecting the right saw blade according to the material characteristics is the first step in achieving high - efficiency cutting," says an industry expert. "The matching between the saw blade and the stone material directly affects the cutting quality and efficiency."
When it comes to diamond concentration, a higher concentration usually means better cutting performance, but it also increases the cost. For high - hardness stones, a concentration of 75% - 85% is often recommended. The hardness of the matrix should be selected according to the hardness of the stone. For softer stones, a softer matrix can be used to ensure better self - sharpening of the saw blade, while for harder stones, a harder matrix is required to maintain the shape of the cutting edge.
The tooth shape design also plays a crucial role. Different tooth shapes are suitable for different cutting requirements. For example, a trapezoidal tooth shape is suitable for rough cutting, while a triangular tooth shape can provide more precise cutting.
In industrial applications, different cutting schemes have different effects. By comparing various scenarios, it is found that the combination of fine - particle size and high - density diamond configuration, along with a good heat - dissipation structure, can significantly improve cutting efficiency. For example, in tile processing, this configuration can reduce edge chipping, and in granite cutting, it can prevent sintering.
| Cutting Scheme | Cutting Efficiency | Cutting Quality |
|---|---|---|
| Fine - particle + High - density Diamond | High | Good |
| Ordinary Diamond | Medium | Average |
