PCD刀具材料的主要優(yōu)點：①PCD的硬度可達8000HV，為硬質(zhì)合金的80～120倍；②PCD的導(dǎo)熱系數(shù)為700W/mk，為硬質(zhì)合金的1.5～9倍，甚至高于PCBN和銅，因此PCD刀具熱量傳遞迅速；③PCD的磨擦系數(shù)一般僅為0.1～0.3（硬質(zhì)合金的磨擦系數(shù)為0.4～1）,因此PCD刀具可顯著減小切削力；④PCD的熱膨脹系數(shù)僅為0.9×10－6～1.18×10－6，僅相當于硬質(zhì)合金的1/5，因此PCD刀具熱變形小，加工精度高；⑤PCD刀具與有色金屬和非金屬材料間的親和力很小，在加工過程中切屑不易粘結(jié)在刀尖上形成積屑瘤；⑥由于PCD燒結(jié)體表現(xiàn)為各向同性，因此不易沿單一解理面裂開。 比拓超硬材料有限公司通過獨特的高溫高壓方式合成的刀具用PCD材料，具有高金剛石－金剛石鍵合，可廣泛應(yīng)用于非鐵金屬、非鐵金屬合金材料的高速高效加工，具有高耐磨性、高穩(wěn)定性特點。 PCD Blanks for tools-----Premium quality from B-to-O ?
