產品工件底孔的預JJN-R
(1)應秉著攻絲加工量盡量小的要明,預加工產品工件的底孑L規格,尤其是美國標準NPT螺紋和國際英標F,R螺紋,其光潔度為1:16,而大部分不銹鋼廠家是按螺紋的小端直徑鑄造出直孔做為攻絲底孑L,油管接頭導致攻絲的下半部分加工量很大,非常容易惹起下列欠佳結果:
①攻絲扭距很大,絲錐易破裂或崩刃;
②攻出的螺紋光澤度較弱;
③攻出的圓柱體螺紋寧波市三通接頭用塞規檢驗時直徑偏小,卡套式接頭原因并并不是螺紋中徑不矛盾,只是因切削劃傷螺紋,存有毛邊。
(2)底孑L規格好為被生產加工螺紋的小路規格再加上0.10.2MM的容量。
(3)攻絲前的擴孑L生產加工好選用訂制鉸刀。有關美國標準NF,R螺紋和國際英標F,R螺紋,應生產加工成光潔度底孑L。現階段很多公司選用廢棄絲錐手工制作磨掉螺紋制成鉸刀,使廢絲錐獲得二次運用。
