8、復合絲攻:有鉆頭(tou)絲(si)攻[A型(鑄鐵(tie)用(yong))鉆頭(tou)絲(si)攻、B型(鋼用(yong))鉆頭(tou)絲(si)攻]、增徑絲(si)攻、帶(dai)絞(jiao)刀(dao)絲(si)攻、異(yi)徑絲(si)攻、帶(dai)道桿絲(si)攻。
9、刃部可換絲攻:殼型絲攻、鑲刃絲攻。
10、其他:直徑增(zeng)大絲攻(gong)、種(zhong)絲。
二、螺絲攻頭攻和二攻之間的區別
絲錐(zhui)的(de)頭(tou)攻和二攻之間的(de)區別如下:
1、造型不同 頭攻(gong)(gong)前(qian)端多了一小段(duan)攻(gong)(gong)形的(de)不(bu)完(wan)全螺紋(wen)部(bu)分,在攻(gong)(gong)絲(si)過程中起導向(xiang)和降低切削力的(de)作用。二攻(gong)(gong)沒有(you)不(bu)完(wan)全螺紋(wen)部(bu)分。 2、攻絲對象不同 在攻通孔螺紋時,只需用頭(tou)攻就可以(攻到導向部(bu)分完全(quan)露(lu)出為止)。 對于盲孔(kong)螺紋,如果想(xiang)充分利用(yong)鉆(zhan)孔(kong)深度(du),以得到盡可能長的(de)完整螺紋,則需使用(yong)二攻,二攻特別適用(yong)于盲孔(kong)螺紋長度(du)與孔(kong)深尺寸相(xiang)差(cha)較小的(de)場合。 3、前部錐體不同 頭攻(gong)前部攻(gong)體長(chang),便于導(dao)向,容易(yi)攻(gong)入。 二攻(gong)前部攻(gong)體短,使螺紋更圓滑,螺絲(si)能夠輕易的擰進去(qu)。 4、外觀上不同 頭(tou)攻的切削部分斜度較長,一般有5-7個(ge)(ge)不完整牙(ya)(ya)形;二攻較短(duan),只(zhi)有1-2個(ge)(ge)不完整牙(ya)(ya)形。頭(tou)攻前部攻體長,便于(yu)導向;二攻前部攻體短(duan)。 5、分類方式上不同 絲錐是用來加工內螺紋的刀具,是指碳素工具鋼或合金工具鋼滾牙(或切牙)絲錐,適用于手工(gong)(gong)攻(gong)(gong)絲。按加工(gong)(gong)方式分類(lei)中的(de)機(ji)用絲錐一般為一支,手用絲攻(gong)(gong)可分為三個一組或兩個一組,即(ji)頭攻(gong)(gong)、二攻(gong)(gong)、三攻(gong)(gong)。 6、使用順序不同 頭(tou)攻(gong)(gong)先(xian)攻(gong)(gong)出(chu)螺(luo)紋(wen)(wen)的(de)(de)輪廓,二攻(gong)(gong)在其基礎(chu)上把螺(luo)紋(wen)(wen)做的(de)(de)更圓滑,使螺(luo)絲能夠(gou)輕易(yi)的(de)(de)擰(ning)進去!頭(tou)攻(gong)(gong)是用來攻(gong)(gong)第一(yi)次的(de)(de),二攻(gong)(gong)是用來攻(gong)(gong)第二次的(de)(de)。使用的(de)(de)時候一(yi)般(ban)通過(guo)專(zhuan)用扳手(shou)進行切削。
