數控車床加工：精密五金零件加工設備零件的處理原則

數控車床加工：精密五金零件加工設備零件的處理原則
1、精(jing)密五金零(ling)(ling)件(jian)(jian)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)為了更(geng)(geng)好地確保機(ji)器設備(bei)零(ling)(ling)件(jian)(jian)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)精(jing)度，粗(cu)(cu)、精(jing)機(ji)械零(ling)(ling)件(jian)(jian)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)更(geng)(geng)好是分(fen)(fen)離開展(zhan)。由(you)于(yu)粗(cu)(cu)機(ji)械零(ling)(ling)件(jian)(jian)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)時，鉆削量(liang)大，產(chan)(chan)品工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)所受切削速度、夾持力(li)大，熱(re)值(zhi)多，及其機(ji)械零(ling)(ling)件(jian)(jian)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)表層有較明顯的(de)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)硬底(di)化狀況，產(chan)(chan)品工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)內部具(ju)有著很大的(de)熱(re)應力(li)，假如粗(cu)(cu)、粗(cu)(cu)機(ji)械零(ling)(ling)件(jian)(jian)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)持續開展(zhan)，則精(jing)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)后的(de)零(ling)(ling)件(jian)(jian)精(jing)度會由(you)于(yu)壓力(li)的(de)再(zai)次劃(hua)分(fen)(fen)而迅速缺失。針對(dui)一些機(ji)械零(ling)(ling)件(jian)(jian)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)精(jing)度規定高的(de)零(ling)(ling)件(jian)(jian)。在(zai)粗(cu)(cu)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)以后和(he)精(jing)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)以前，還應安排(pai)超(chao)低(di)溫淬火或固溶處理步驟(zou)來清除熱(re)應力(li)。 

2、精密五金零件加工有效地采用機器設備。粗機器設備零件加工主要是切除絕大多數加工容量，并不需要有較高的機械零件加工精度，因此粗加工應在輸出功率比較大、精度不太高的設備上開展，精加工工藝流程則需求用較高精度的數控車床加工。粗、精加工各自在不一樣的設備上加工，既能發揮設施工作能力，又能增加精密機床的使用期限。 

3、精密五金零(ling)(ling)(ling)件(jian)加(jia)(jia)(jia)工(gong)在(zai)機(ji)(ji)器(qi)設備零(ling)(ling)(ling)件(jian)加(jia)(jia)(jia)工(gong)加(jia)(jia)(jia)工(gong)工(gong)藝(yi)風格中，常安排(pai)有(you)熱(re)處理(li)(li)工(gong)藝(yi)工(gong)藝(yi)流程(cheng)。熱(re)處理(li)(li)工(gong)藝(yi)工(gong)藝(yi)流程(cheng)部位的安排(pai)如下所示：為(wei)改進金屬材料(liao)的鉆削加(jia)(jia)(jia)工(gong)特(te)性，如淬(cui)火、淬(cui)火、熱(re)處理(li)(li)等，一般安排(pai)在(zai)機(ji)(ji)械(xie)零(ling)(ling)(ling)件(jian)加(jia)(jia)(jia)工(gong)前開展(zhan)。為(wei)清除熱(re)應(ying)力(li)，如調質(zhi)處理(li)(li)、調質(zhi)熱(re)處理(li)(li)等，一般安排(pai)在(zai)粗加(jia)(jia)(jia)工(gong)以(yi)后(hou)(hou)，精加(jia)(jia)(jia)工(gong)以(yi)前開展(zhan)。為(wei)了更好地提(ti)升零(ling)(ling)(ling)件(jian)的物理(li)(li)性能(neng)，如滲氮、熱(re)處理(li)(li)、淬(cui)火等，一般安排(pai)在(zai)機(ji)(ji)械(xie)零(ling)(ling)(ling)件(jian)加(jia)(jia)(jia)工(gong)以(yi)后(hou)(hou)開展(zhan)。如熱(re)處理(li)(li)工(gong)藝(yi)后(hou)(hou)有(you)很大的形變(bian)，還須安排(pai)最后(hou)(hou)加(jia)(jia)(jia)工(gong)工(gong)藝(yi)流程(cheng)。
