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.

Drawing dies are widely used, such as high-precision wires used in electronic devices, radars, televisions, instruments and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wire and cable wires and various alloy wires are all drawn with diamond drawing dies. The diamond wire drawing die made of natural diamond has strong wear resistance and extremely high service life due to the use of natural diamond as raw material.
