El procesamiento de herramientas PCD

The cutting edge geometry and final dimensions of the PCD tools are usually ground on CNC tool grinding machine. However, ultra-hard tools with polycrystalline diamond (PCD) cutting edges pose a challenge for grinding. In fact, grinding a PCD tip with the hardest diamond grinding wheel takes a lot of time and loss of grinding wheels. Faced with two substances of the same hardness and trying to use one to remove the other. The final result is that the wear rate of the grinding wheel almost reaches 1∶1 loss and it is too high. Por lo tanto, mejorar la eficiencia del perfeccionamiento de las herramientas de PCD, principalmente en los siguientes aspectos. 1.Suficiente rigidez y estabilidad. 2. Mecanismo uniforme de columpio de rueda de molienda. 3. Fuerza de enjuague. 4. Refrigerante totalmente suministrado.
