In the realm of high-end construction projects, the choice of cutting tools is crucial, especially when dealing with high-hardness materials such as granite. High-wear-resistant matrix diamond saw blades have emerged as the preferred option for these projects. This article delves into the technical principles behind these saw blades and provides a selection guide, aiming to assist technicians in the stone processing, decoration, and construction industries.
Granite is a widely used high-hardness material in construction. Its unique grain structure, composed of quartz, feldspar, and mica, poses significant challenges during the cutting process. According to industry statistics, approximately 70% of the issues in granite cutting are related to excessive saw blade wear. The special grain structure of granite can cause uneven wear on the saw blade, reducing its cutting efficiency and lifespan.
The grain structure of granite has a direct impact on saw blade wear. Quartz, one of the main components of granite, has a Mohs hardness of 7, which is much higher than the hardness of most saw blade materials. When the saw blade cuts through granite, the hard quartz grains rub against the saw blade, causing abrasion. A study by the International Stone Cutting Association found that in continuous cutting operations, the wear rate of saw blades on granite can be up to 3 times higher than that on softer materials.
| Material | Mohs Hardness | Saw Blade Wear Rate (compared to softer materials) |
|---|---|---|
| Granite (Quartz) | 7 | Up to 3 times |
| Softer Stone | 3 - 5 | Normal |
To address the issue of saw blade wear in granite cutting, high-concentration, high-wear-resistant matrix diamond saw blades are essential. These saw blades are made with a high concentration of diamonds, which have a Mohs hardness of 10, the highest in nature. The high-wear-resistant matrix can effectively hold the diamonds in place, ensuring continuous and efficient cutting. A case study of a large-scale stone processing plant showed that after switching to high-concentration, high-wear-resistant matrix diamond saw blades, the cutting efficiency increased by 40%, and the saw blade replacement frequency decreased by 60%.
In addition to using high-quality saw blades, optimizing the cutting process can also improve cutting quality and efficiency. Adjusting the cutting path, using the multi-stage feed method, and saw blade dressing are effective techniques. For example, by adjusting the cutting path, the saw blade can avoid direct contact with the hardest parts of the granite, reducing wear. The multi-stage feed method can evenly distribute the cutting force, preventing excessive wear on a single part of the saw blade. Saw blade dressing can restore the sharpness of the saw blade, ensuring consistent cutting performance.
