style="text-indent:25px">合金圓鋼是一種很難進(jìn)行切削加工的管材，合金圓鋼由于具有很大的粘性和快速冷作硬化的傾向，加工難度極大。雖然具有很好的韌性和強(qiáng)度，但也極易發(fā)生冷作硬化。而在進(jìn)行攻絲上也常常出現(xiàn)一些問題。合金圓鋼攻絲的問題通常表現(xiàn)為螺紋粗糙和破損、工件材料咬死絲錐并導(dǎo)致其折斷。絲錐本身的缺點(diǎn)(如切削刃幾何形狀不正確、基體材料和涂層選用不當(dāng))可能是根本的原因。不過，通常還有一些其他原因。合金圓鋼的攻絲加工需要使用具有高潤(rùn)滑性的冷卻液。攻絲通常是切削負(fù)荷的加工方式之一，如果冷卻液的潤(rùn)滑性不足，其不利影響將比大多數(shù)其他加工更快地顯現(xiàn)出來。合肥圓鋼規(guī)范合金圓鋼的硬度非常的高。</p><div
