Stone cutting machine saw blades are essential for precision and efficiency in cutting operations. However, there are several common cutting problems that operators may face, and understanding these issues can help you avoid costly repairs and improve cutting performance:
1. Cutting burnt blades: If a stone cutting machine saw blade is too hard, the diamonds on the blade may not adhere properly, causing them to fall off prematurely. Additionally, if the diamond blade height is insufficient, it can result in uneven cutting. This issue may lead to a burnt appearance on the blade, and operators should check the blade condition regularly to prevent this.
2. Cutting sparks: The sparking phenomenon can occur if the diamond distribution on the blade is improper, or if the body of the blade is either too hard or too soft. This can lead to overheating during the cutting process, producing sparks. To prevent this, ensure that the blade material is of high quality and that the diamonds are evenly distributed across the cutting surface.
3. Cutting jump blades: Jumping blades are caused by improper diamond shedding in the saw blade. This happens when the diamonds are not evenly distributed within the blade’s body. Some areas may have too many diamonds, while others have too few. As a result, the blade experiences uneven cutting, leading to jumping and instability. Regular inspection of the blade and ensuring uniform diamond distribution can help prevent this issue.
4. Cutting off blocks: Material segregation in the sintered body of the saw blade is another common problem. When the structure of the blade is loose, material segregation can cause the saw blade to detach during cutting. This can result in dangerous situations or costly downtime. Operators should choose saw blades with a solid and uniform structure to avoid this problem.
5. Cutting is not sharp: When a saw blade becomes dull, it may not cut efficiently, leading to poor performance. During the heating and sintering process, the temperature difference between the tooth top and root, combined with the state of the powder and distribution of low-melting-point materials, can alter the sintered structure of the blade. Additionally, heat accumulation during cutting weakens the mechanical properties of the weld body, reducing the blade's sharpness. Vibration and impact forces can further weaken the grip of the blade on the diamond, causing it to lose its cutting effectiveness. Regular sharpening and cooling techniques can help maintain sharpness and cutting efficiency.
By addressing these common cutting problems, stone cutting machine operators can improve the performance and longevity of their saw blades, reducing downtime and increasing productivity.
