焊接式PCBN刀具复合片是复合超硬刀具材料中比较成熟的产品形态，将立方氮化硼与结合剂通过HPHT工艺直接与硬质合金基体合成为聚晶立方氮化硼复合片，复合层具有立方氮化硼聚晶体的耐磨性能和各向同性，基体拥有硬质合金的抗断裂韧性和易焊接性。经激光切割或电火花切割可预制成各种形态的刀粒毛坯，材料通用性好，客制化程度高。
长鹰硬科的焊接式PCBN刀具复合片涵盖1μm至15μm的晶粒度范围，CBN含量范围涵盖40%至90%，分为通用性好的F系列牌号和耐磨性强化的H系列牌号，适用于铸铁、淬火钢、高温合金等的连续/断续通用粗/精加工，复合片毛坯直径＞55mm，复合层均匀无缺陷。
常备货源充足，复合层厚度与复合片厚度可定制，依客户需要可切割成任意刀粒供货。
