近年来，聚晶金刚石（PCD）和立方氮化硼（CBN）刀具、刀片和压坯的精加工技术取得了进步，从而实现了之前通过手动或批量加工方法进行的最终磨边和/或珩磨操作的自动化。这项新技术采用了柔性超硬磨光工具，由PCD或CBN晶体或粉末组成，均匀分布在特殊的弹性塑料长丝中，制成径向轮和其他形状，适用于高强度环境- 精密自动化计算机数控机床。这种新的超硬磨料应用和加工技术建立并改进了目前在自动化机械和设备上使用碳化硅矿物和弹性尼龙长丝径向砂轮形式对硬质合金和陶瓷刀具刀片进行的高产量半径磨削。

RECENT ADVANCEMENTS IN THE FINE FINISHING OF POLYCRYSTALLINE DIAMOND (PCD) AND CUBIC BORON NITRIDE (CBN) CUTTING TOOLS, INSERTS, AND COMPACTS HAVE LED TO THE AUTOMATION OF THE FINAL EDGE RADIUSING AND/OR HONING OPERATIONS PREVIOUSLY BEING PERFORMED BY MANUAL OR BATCH PROCESSING METHODS. THE NEW TECHNOLOGY EMPLOYS FLEXIBLE SUPERABRASIVE FINISHING TOOLS COMPRISED OF PCD OR CBN CRYSTALS OR POWDERS HOMOGENEOUSLY DISTRIBUTED THROUGHOUT SPECIAL RESILIENT PLASTIC FILAMENTS MADE INTO RADIAL WHEEL AND OTHER SHAPES, SUITABLE FOR USE ON HIGH-PRECISION AUTOMATED COMPUTER NUMERICAL CONTROLLED MACHINE TOOLS. THIS NEW SUPERABRASIVE APPLICATION AND PROCESS TECHNOLOGY BUILDS AND IMPROVES UPON THE PRESENT HIGH-PRODUCTION RADIUS GRINDING OF CARBIDE AND CERAMIC CUTTING TOOL INSERTS USING SILICON CARBIDE MINERALS WITH RESILIENT NYLON FILAMENTS IN RADIAL WHEEL FORMS ON AUTOMATED MACHINERY AND EQUIPMENT.
