多晶人造金刚石(PCD)使用实践证明,修整器的磨损是在各个细颗粒单晶金刚石上发生的,随着修整器的不断磨损,各个单颗粒金刚石不断脱落,新的锋利颗粒不断露出表面,因而修整器具有良好的自锐性,使被修整的砂轮获得理想的型面,能有效地完成磨削加工。多晶人造金刚石在修整中对砂轮表层的磨粒磨损较小,因而修整后的砂轮锋利。从微观范围看,天然金刚石修整器的金刚石具有比人造金刚石聚晶更高的硬度和更大的接触面,因此在修整过程中对砂轮表层的磨粒的磨损 The use of polycrystalline diamond (PCD) has proved that the wear of the dresser occurs on all the fine single crystal diamonds. With the constant wear of the dresser, each single diamond continuously falls off and the new sharp particles continuously expose the surface. Therefore, the dresser has a good self-sharpening, so that the dresser wheel obtains the ideal profile, which can effectively finish the grinding process. Polycrystalline synthetic diamond in the dressing of the abrasive surface of the wheel wear less, so trim the wheel sharp. From a microscopic point of view, natural diamond dresser diamond has a higher hardness and a larger contact surface than artificial diamond polycrystalline, so wear on the surface of the wheel during the dressing process
