精(jing)密零(ling)(ling)件行業的(de)(de)(de)(de)(de)標(biao)準是非(fei)常嚴格的(de)(de)(de)(de)(de)，加工(gong)(gong)(gong)時候(hou)有進刀(dao)，出刀(dao)等(deng)不(bu)(bu)同(tong)(tong)(tong)的(de)(de)(de)(de)(de)流程工(gong)(gong)(gong)序。尺寸也會(hui)根據產(chan)品有不(bu)(bu)同(tong)(tong)(tong)的(de)(de)(de)(de)(de)具體需(xu)求(qiu)，加工(gong)(gong)(gong)精(jing)度的(de)(de)(de)(de)(de)要(yao)(yao)(yao)求(qiu)也會(hui)不(bu)(bu)同(tong)(tong)(tong)，總體來(lai)說精(jing)密加工(gong)(gong)(gong)精(jing)度的(de)(de)(de)(de)(de)要(yao)(yao)(yao)求(qiu)是非(fei)常高的(de)(de)(de)(de)(de)，有時候(hou)甚至精(jing)確到1mm下的(de)(de)(de)(de)(de)多(duo)少微米(mi)差(cha)別，尺寸如(ru)果差(cha)別很大(da)產(chan)品就(jiu)會(hui)成(cheng)為廢(fei)品，就(jiu)需(xu)要(yao)(yao)(yao)返(fan)工(gong)(gong)(gong)來(lai)達到要(yao)(yao)(yao)求(qiu)，這個過程非(fei)常費(fei)時費(fei)力，有時候(hou)會(hui)使得(de)所有的(de)(de)(de)(de)(de)原(yuan)材料報廢(fei)，造成(cheng)成(cheng)本的(de)(de)(de)(de)(de)增(zeng)加，與此同(tong)(tong)(tong)時零(ling)(ling)件也必(bi)然是無法用(yong)了，因此精(jing)密零(ling)(ling)件加工(gong)(gong)(gong)是有很多(duo)要(yao)(yao)(yao)求(qiu)的(de)(de)(de)(de)(de)。那么精(jing)密零(ling)(ling)件加工(gong)(gong)(gong)有哪些(xie)要(yao)(yao)(yao)求(qiu)呢？

(1)通常(chang)為(wei)了確保零(ling)件(jian)的(de)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)精度(du)，粗(cu)零(ling)件(jian)與(yu)精密(mi)(mi)(mi)機械零(ling)件(jian)的(de)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)必須分(fen)開來運行(xing)，因為(wei)粗(cu)零(ling)件(jian)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)與(yu)精密(mi)(mi)(mi)零(ling)件(jian)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)的(de)切削量，夾緊力，發熱(re)量，工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)所(suo)受的(de)切削力都不一樣(yang)，如(ru)果(guo)粗(cu)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)與(yu)精密(mi)(mi)(mi)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)連(lian)續進行(xing)，精密(mi)(mi)(mi)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)零(ling)件(jian)的(de)精度(du)會因為(wei)應(ying)力的(de)不同而(er)喪失。

(2)設備選用的(de)合理性。粗零(ling)件的(de)加(jia)工(gong)對加(jia)工(gong)精(jing)度的(de)要求(qiu)并不高，只是(shi)主(zhu)要對加(jia)工(gong)余量切割，所以(yi)精(jing)密加(jia)工(gong)要求(qiu)在非常高精(jing)度的(de)機床加(jia)工(gong)。

(3)在(zai)精密零件(jian)加(jia)工(gong)(gong)工(gong)(gong)藝路線(xian)中，常(chang)安(an)排(pai)(pai)有熱處理(li)工(gong)(gong)序。熱處理(li)工(gong)(gong)序位置的(de)安(an)排(pai)(pai)如下(xia)：為改善金屬的(de)切削加(jia)工(gong)(gong)性能，如退火、正火、調質(zhi)等(deng)，一般(ban)安(an)排(pai)(pai)在(zai)機(ji)械(xie)零件(jian)加(jia)工(gong)(gong)前進行。

(4)一(yi)般來說(shuo)精密零件加工幾乎(hu)都有熱處理(li)工序(xu)(xu)，熱處理(li)工序(xu)(xu)能(neng)夠(gou)改善金屬(shu)的切削加工性能(neng)。
