大連模具加工的切削加工方法和特種加工方法3大類。而且根據生產工藝的要求，所選用的加工設備也各不相同。一般包含車削加工用的各種車床、加工孔類的鉆床、鏜床，成型各種平面或曲面的銑床、磨床及成型較細微的特征或LOGO的雕刻機械等。并以電器盒模具模芯高效數控加工工藝為例，結合自己多年的注射模具加工經驗，精辟(pi)地介(jie)紹了模具零(ling)部件(jian)高效銑削加工工序(xu)的(de)編制，希望對工程技術人員有一定的(de)幫(bang)助和(he)借鑒作用。

  高速加(jia)工(gong)(gong)(gong)(gong)技(ji)術已越(yue)來越(yue)多地應(ying)用(yong)(yong)于(yu)模具(ju)的(de)(de)(de)制造(zao)加(jia)工(gong)(gong)(gong)(gong)。高速加(jia)工(gong)(gong)(gong)(gong)技(ji)術對(dui)模具(ju)加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝(yi)產生了巨(ju)大(da)影(ying)響，改(gai)變了傳(chuan)統模具(ju)加(jia)工(gong)(gong)(gong)(gong)采用(yong)(yong)的(de)(de)(de)“退(tui)火→銑削(xue)(xue)加(jia)工(gong)(gong)(gong)(gong)→熱(re)處理→磨削(xue)(xue)”或“電火花(hua)加(jia)工(gong)(gong)(gong)(gong)→手工(gong)(gong)(gong)(gong)打磨、拋光”等(deng)復雜冗長(chang)的(de)(de)(de)工(gong)(gong)(gong)(gong)藝(yi)流程(cheng)。結構形狀、尺寸、精度和使用(yong)(yong)壽命等(deng)方面(mian)的(de)(de)(de)不(bu)同要求。

  采(cai)用合(he)理(li)的加(jia)工方法和工藝(yi)路線。盡可能通過加(jia)工設備來保證模具零部件的加(jia)工質(zhi)量，減少鉗工修配工作量，提高生(sheng)產效率和降低成本。結合(he)本企業實際生(sheng)產條件進(jin)行(xing)制定(ding)，技術上要先進(jin)、經濟上要合(he)理(li)。模具零部件加(jia)工工藝(yi)規程制定(ding)的一般步驟及所包含的基本內容。

  應避免刀具垂直插入工(gong)(gong)(gong)(gong)件，而應采(cai)用傾斜(xie)下(xia)刀方(fang)式(常用傾斜(xie)角為20°～30°)，采(cai)用螺旋式下(xia)刀以降(jiang)低(di)刀具載荷。如(ru)局部銑削(xue)工(gong)(gong)(gong)(gong)序的剩余(yu)加(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)量取(qu)(qu)值(zhi)與粗加(jia)(jia)工(gong)(gong)(gong)(gong)相等，該工(gong)(gong)(gong)(gong)序只用一把小(xiao)直徑銑刀來清(qing)除(chu)粗加(jia)(jia)工(gong)(gong)(gong)(gong)未切到的角落，然后再進行半(ban)(ban)(ban)精加(jia)(jia)工(gong)(gong)(gong)(gong)；如(ru)果(guo)取(qu)(qu)局部銑削(xue)工(gong)(gong)(gong)(gong)序的剩余(yu)加(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)量值(zhi)作(zuo)為半(ban)(ban)(ban)精加(jia)(jia)工(gong)(gong)(gong)(gong)的剩余(yu)加(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)量，則該工(gong)(gong)(gong)(gong)序不僅(jin)可(ke)清(qing)除(chu)粗加(jia)(jia)工(gong)(gong)(gong)(gong)未切到的角落，還可(ke)完成半(ban)(ban)(ban)精加(jia)(jia)工(gong)(gong)(gong)(gong)。
