摘要： A method of producing at least one through-hole and countersink in at least one ultrahard insert including the steps of providing a body having a first major surface and an opposite second major surface; forming at least one pilot hole in said body using a laser, wherein said at least one pilot hole extends from said first major surface to the opposite second major surface of said body; cutting said pilot hole using a wire electrical discharge machine (WEDM) to produce a straight cylindrical portion and top conical portion; forming a countersink on at least one side of said body using an electrical discharge grinding machine (EDG); and severing said at least one ultrahard insert from said body forming a finished insert, wherein said finished insert includes a through-hole and a countersink.
摘要翻译： 一种在至少一个超硬插入件中产生至少一个通孔和埋头孔的方法，包括提供具有第一主表面和相对的第二主表面的主体的步骤; 使用激光在所述主体中形成至少一个引导孔，其中所述至少一个引导孔从所述主体的所述第一主表面延伸到相对的第二主表面; 使用电线放电机（WEDM）切割所述引导孔，以产生直的圆柱形部分和顶部锥形部分; 使用放电研磨机（EDG）在所述主体的至少一侧上形成锪孔; 以及从所述主体切割所述至少一个超硬镶嵌件，形成成品刀片，其中所述成品刀片包括通孔和埋头孔。
