Penggilingan mata pisau PCD berdasarkan jenis alat pemotong dapat dibagi menjadi dua jenis gilingan yang berbeda, terutama untuk gilingan sudut terbalik dan gilingan bulat luar.
Alat pisau PCD sebagian besar digunakan untuk penggiling bulatan luar dan penggiling manual. Paduan keramik, ampela batu, memiliki tingkat efisiensi yang tinggi, daya tahan yang tinggi, dan mengolahnya menjadi rendah. Ukuran, konsentrasi, dan kombinasi ampela batu Vajra sangat berpengaruh pada kualitas gilingan dan efisiensi alat pisau PCD.
For example, a grinding wheel with a small particle size can obtain a lower abrasive surface roughness. The influence rule of the grinding wheel speed on the surface roughness is as follows: if the surface roughness value is larger, the rotation speed is higher or lower, at the optimal value, the rotation speed is medium, at the optimal value and the surface quality is good. The effect law of grinding pressure on surface roughness is just the opposite: when the grinding pressure is in the middle level, the surface roughness value is the largest, while when the grinding pressure is high (such as 5.5pa) and low (such as 2.5pa), the corresponding surface roughness is almost the same, which is different from the traditional grinding law. Generally speaking, on the premise that machining quality requirements can be met, grinding wheels with larger particle size should be selected as far as possible.
At present, the diamond grinding wheel with good processing effect is TY — ROLIT, because the diamond grinding grains are arranged in an orderly manner, and the grinding rate is 20 to 30 times that of the grinding wheel with the disordered arrangement of grinding grains, but the grinding cost is also relatively high.PCD tool grinding on grinding pressure, cooling fluid and other strict requirements. The optimum speed of PCD tool grinding should be 2500r/min(150mm diameter of a grinding wheel). The coolant concentration is 4%, the grinding pressure is 150N, and the surface roughness of the PCD tool can reach ra0.012um.
Dalam menggunakan alat PCD, juga diperlukan metode gilingan spesifik yang dipilih sesuai dengan kondisi kita yang sebenarnya.
