    丝锥

    丝锥也叫丝攻,是加工各种中、小尺寸内螺纹的刀具,沿轴向开有沟槽。它结构简单,使用方便,既可手工操作,也可以在机床上工作,在生产中应用得非常广泛。

    丝锥的类型

    • 直槽丝锥:加工容易,精度略低,产量较大。一般用于普通车床,钻床及攻丝机的螺纹加工用,切削速度较慢。
    • 螺旋槽丝锥:多用于数控加工中心钻盲孔用,加工速度较快,精度高,排屑较好、对中性好。
    • 螺尖丝锥:切削部分磨有斜槽,形成负的刃倾角(见刀具),切削时切屑向前排出,适于加工通孔。
    • 挤压丝锥:靠挤压孔壁时金属的塑性变形形成螺纹,主要用于加工铝合金、铜等塑性材料,也可加工低碳钢和不锈钢。

    如何选择合适的丝锥?

    • 直槽丝锥通用性最强,通孔或不通孔、有色金属或黑色金属均可加工,价格也最便宜。但是针对性也较差,什么都可做,什么都不是做得最好。
    • 螺旋槽丝锥比较适合加工不通孔螺纹,加工时切屑向后排出。加工黑色金属的,螺旋角选的小一点,一般在30度左右,保证螺旋齿的强度。加工有色金属的,螺旋角选的大一点,可在45度左右,切削锋利一些。
    • 螺尖丝锥加工螺纹时切屑向前排出。
    • 挤压丝锥比较适合加工有色金属。
