1. The grinding wheel is blocked. After grinding a large number of workpieces, the grinding wheel turns black, indicating that the debris during grinding did not fall off in time and adhered to the surface of the grinding wheel. Therefore, the surface of the grinding wheel may be blocked by the grinding debris. At this time, it is necessary to use an oil stone or a dressing wheel to the diamond grinding wheel.
2. The temperature of the grinding wheel is too high. During the grinding process, the coolant is used less, and the grinding heat increases. At this time, it is necessary to increase the amount of coolant to reduce the temperature of the grinding wheel and the workpiece.
3. The feed amount is too large. The grinding wheel feed rate is large, the cutting thickness of a single abrasive grain increases, and the heat generated increases, which increases the grinding temperature and also causes the grinding wheel to turn black. It is necessary to appropriately reduce the grinding wheel feed rate.
4. The hardness of the grinding wheel itself is too high. The grinding wheel is selected to be too hard, and the blunt abrasive grains are not easy to fall off. The workpiece material is PCD. The harder the workpiece material, the softer the hardness of the grinding wheel should be selected to make the blunt abrasive particles fall off quickly, so that the grinding wheel always keeps sharp abrasive particles at work to avoid workpiece burns and debris from blocking the grinding wheel.

During the production process of ceramic diamond grinding wheels, raw materials such as diamonds and binders need to strictly control humidity and temperature. Excessive humidity may cause raw materials to absorb moisture, affecting the bonding strength and hardness of the grinding wheel; while excessive temperature may cause volatilization or unstable quality of certain materials, thus affecting the overall performance of the grinding wheel.
Single crystal diamond cutting tools are high-performance tools made from single crystal diamond, known for their exceptional hardness, wear resistance, and thermal conductivity.Effective grinding methods include using diamond grinding wheels, laser grinding, and mechanical grinding with cast iron or steel discs, each with its own advantages and requirements. Moresuperhard offers various solutions and consumables for grinding single crystal diamond tools, ensuring efficient production and high-quality results.
