描述:
活塞由硅含量较高的铝制成,因此是一种非常耐磨的材料。
高硅铝合金比其它铝合金具有更高的硬度和耐磨性,切削时,刀具交替切削较软的铝基和较硬的硅粒,硬质合金刀片易磨损,也易产生积屑瘤,影响粗糙度和加工精度。
为了避免积屑瘤和加工硬化,切削刃必须锋利,切削刃必须光滑,PCD刀具正好满足了这些要求。加工这样的材料需要高耐磨性的刀具,比如用PCD制成的刀具和刀片。
细节
(1)PCD的硬度可达8000HV以上,是硬质合金的8~12倍。
(2)PCD的热导率高达700W/mk,是硬质合金的1.5~9倍,甚至高于PCBN和铜合金;
(3)PCD的摩擦系数和膨胀系数较小;
(4)PCD与有色金属和非金属材料之间的亲和力小;
(5)刃口锋利度及刀面粗糙度
PCD 活塞开槽刀具的应用: 用于加工硬质黑色金属,例如硬化钢和灰铸铁。PCBN 刀片广泛用于加工刹车盘、发动机缸套、发动机缸体、刹车鼓、阀座和导管、齿轮和模具等。
