When working with stone engraving machines, having the right tools is essential for achieving high-quality results. To excel in this field, it’s crucial to ensure your tools are properly sharpened. Selecting the right tools alongside choosing a quality machine can significantly enhance your work efficiency. Depending on the type of stone carving you're undertaking—be it relief, engraving, line carving, or others—it's important to pick the appropriate tool to maximize productivity.
Common types of stone carving processes include relief carving, engraving, line carving, Yin-Yang carving, milling, groove cutting, cutting, and opposing arc carving. Let’s delve into the classification and selection of tools used in these processes to help guide your choices effectively.
1. Alloy Tools: These consist of multiple metals, come with a blade, and are relatively affordable. Alloy tools are typically used for softer stones like bluestone, white marble, and marble with a Mohs hardness below 5.
2. Brazed Tools: Made by firing artificial carbide particles onto the tool rod via electric furnaces, these tools are moderately priced. Brazed tools are suitable for soft stones like bluestone and can handle various carving methods, though their use on granite is limited.
3. Sintered Tools: Created by melting copper and iron and mixing them with carbide particles, sintered tools have carbide both on the surface and inside. They are more versatile, especially for harder stones like granite, and are effective across all carving methods.
4. PCD Diamond Tools: Featuring precision-cut blades welded to a shaped rod, these tools are highly durable and suited for harder stones such as granite and marble. However, they come at a premium price.
Comparing brazed and sintered tools, brazed tools have carbide only on the surface, making them prone to wear and eventual damage. Sintered tools, on the other hand, retain carbide within their structure even after surface wear, making them more resilient but potentially leading to shorter tool life due to gradual shortening. Additionally, brazed tools tend to be stronger and easier to find in the market, whereas sintered tools are harder to source from reliable manufacturers.
For specific applications, the C-series melting diamond grinding head knife, made with advanced military-grade technology, is ideal for high-efficiency relief carving and large character engraving. The D-series integrated alloy triangular knife offers excellent wear resistance and lettering results. The E-series PCD polycrystalline diamond knife is perfect for engraving small granite characters, requiring careful handling to prevent excessive pressure. The F-series sintered diamond grinding head cutter excels in granite milling, with a long tool life, and the G-series diamond four-edged knife is ideal for small granite characters and line carving.
If you’re unsure about any aspect, feel free to reach out. Dingxin Engraving Machine specializes in producing various stone engraving machines, and we hope you'll consider supporting us. For marble, custom flat-bottom sharp knives are available to meet specific needs.
In summary, selecting the right tool depends on the type of stone and carving method. By understanding the unique features and applications of each tool category, you’ll be better equipped to select the best options for your projects.
