PCD 커터 칼날 연마는 커터 유형에 따라 서로 다른 연삭 유형으로 나눌 수 있으며, 크게 모따기 연삭과 외원 연삭의 두 가지 유형으로 구분할 수 있다.
PCD 커터는 외원 연삭기와 수동 연마기에 주로 사용된다.세라믹 결합제인 금강석 사륜은 연삭 효율이 높고 내구성이 높고 가공비용이 낮다는 장점이 있다.다이아몬드 사륜의 크기, 농도, 결합제는 PCD 커터의 연삭 품질과 효율성에 큰 영향을 미친다.
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.
