合金絞刀是一種機床(chuang)金屬加工(gong)工(gong)具(ju)，用以切除孔已加工(gong)表(biao)面薄金屬層。

合金絞刀有(you)一個或者(zhe)多個刀(dao)(dao)齒，用(yong)(yong)(yong)(yong)(yong)以切除(chu)孔(kong)已加(jia)工(gong)(gong)表面(mian)薄金(jin)屬層的(de)(de)(de)旋轉(zhuan)刀(dao)(dao)具(ju)。經(jing)過絞刀(dao)(dao)加(jia)工(gong)(gong)后的(de)(de)(de)孔(kong)可以獲得精(jing)確的(de)(de)(de)尺寸和(he)(he)形(xing)狀，用(yong)(yong)(yong)(yong)(yong)于(yu)鉸(jiao)削工(gong)(gong)件上(shang)已鉆削(或擴孔(kong))加(jia)工(gong)(gong)后的(de)(de)(de)孔(kong)，主(zhu)要是為了提高孔(kong)的(de)(de)(de)加(jia)工(gong)(gong)精(jing)度(du)，降低其表面(mian)的(de)(de)(de)粗糙度(du)，是用(yong)(yong)(yong)(yong)(yong)于(yu)孔(kong)的(de)(de)(de)精(jing)加(jia)工(gong)(gong)和(he)(he)半精(jing)加(jia)工(gong)(gong)的(de)(de)(de)刀(dao)(dao)具(ju)，加(jia)工(gong)(gong)余量一般很小。合金(jin)用(yong)(yong)(yong)(yong)(yong)來(lai)(lai)(lai)加(jia)工(gong)(gong)圓柱形(xing)孔(kong)的(de)(de)(de)鉸(jiao)刀(dao)(dao)比(bi)較常用(yong)(yong)(yong)(yong)(yong)。用(yong)(yong)(yong)(yong)(yong)來(lai)(lai)(lai)加(jia)工(gong)(gong)錐形(xing)孔(kong)的(de)(de)(de)鉸(jiao)刀(dao)(dao)是錐形(xing)鉸(jiao)刀(dao)(dao)，比(bi)較少用(yong)(yong)(yong)(yong)(yong)。按使用(yong)(yong)(yong)(yong)(yong)情況(kuang)來(lai)(lai)(lai)看有(you)手(shou)(shou)用(yong)(yong)(yong)(yong)(yong)鉸(jiao)刀(dao)(dao)和(he)(he)機用(yong)(yong)(yong)(yong)(yong)鉸(jiao)刀(dao)(dao)，機用(yong)(yong)(yong)(yong)(yong)鉸(jiao)刀(dao)(dao)又(you)可分為直柄(bing)鉸(jiao)刀(dao)(dao)和(he)(he)錐柄(bing)鉸(jiao)刀(dao)(dao)。手(shou)(shou)用(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)則(ze)是直柄(bing)型的(de)(de)(de)。而(er)合金(jin)鉸(jiao)刀(dao)(dao)主(zhu)要用(yong)(yong)(yong)(yong)(yong)來(lai)(lai)(lai)加(jia)工(gong)(gong)高難硬度(du)材(cai)料。

特點：

1、槽(cao)型(xing)(xing)：刀(dao)刃(ren)為螺(luo)旋型(xing)(xing)刀(dao)刃(ren)，螺(luo)旋型(xing)(xing)刀(dao)刃(ren)之間設容屑槽(cao)，螺(luo)旋型(xing)(xing)刀(dao)刃(ren)端部設有切削(xue)角。

2、優點是切削連續，工作(zuo)過程平(ping)穩，可大大改善(shan)鉸(jiao)刀的切削性(xing)能。采(cai)用螺(luo)旋鉸(jiao)刀，形成斜(xie)角切削，可使(shi)切屑順利(li)排出，鉸(jiao)刀的強度和剛性(xing)得到(dao)提(ti)高，不容易產生崩刃和振(zhen)動(dong)。

3、鉸(jiao)(jiao)刀(dao)(dao)實際工作前角大，刃口鋒利，可避免韌性材(cai)料粘結和出現(xian)拉毛現(xian)象，從而減小了(le)(le)孔壁的(de)表面粗(cu)糙度(du)，且(qie)螺旋(xuan)刃鉸(jiao)(jiao)刀(dao)(dao)較傳統(tong)直齒鉸(jiao)(jiao)刀(dao)(dao)的(de)耐(nai)用度(du)提高(gao)了(le)(le)數倍(bei)，加工精度(du)和質量提高(gao)了(le)(le)兩個精度(du)等級(ji)，解決了(le)(le)在加工中的(de)平(ping)衡問(wen)題(ti)(ti)、過熱(re)問(wen)題(ti)(ti)、崩(beng)裂問(wen)題(ti)(ti)、鈍化等問(wen)題(ti)(ti)。
