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)(ling)件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)為了更好地確保(bao)機(ji)器設備零(ling)(ling)(ling)件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)度(du)(du)(du)，粗、精(jing)機(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)更好是分(fen)離開展(zhan)。由于(yu)粗機(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)時，鉆(zhan)削量大，產(chan)品工(gong)(gong)(gong)(gong)件(jian)(jian)所受(shou)切削速度(du)(du)(du)、夾持力(li)(li)大，熱值多，及其(qi)機(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)表層(ceng)有(you)較(jiao)明顯的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)硬底化狀況，產(chan)品工(gong)(gong)(gong)(gong)件(jian)(jian)內部具有(you)著(zhu)很大的(de)熱應(ying)力(li)(li)，假(jia)如粗、粗機(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)持續開展(zhan)，則精(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)后的(de)零(ling)(ling)(ling)件(jian)(jian)精(jing)度(du)(du)(du)會由于(yu)壓力(li)(li)的(de)再次劃分(fen)而迅速缺失。針對一(yi)些機(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)度(du)(du)(du)規定高的(de)零(ling)(ling)(ling)件(jian)(jian)。在粗加(jia)(jia)工(gong)(gong)(gong)(gong)以(yi)(yi)后和精(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)以(yi)(yi)前(qian)，還(huan)應(ying)安排超低(di)溫淬火或固(gu)溶處理步驟來清除熱應(ying)力(li)(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(jing)密五(wu)金零(ling)件(jian)(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)在(zai)機(ji)器設(she)備零(ling)件(jian)(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)風格中，常安(an)(an)排(pai)有熱(re)處(chu)(chu)理(li)(li)(li)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)流(liu)(liu)程。熱(re)處(chu)(chu)理(li)(li)(li)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)流(liu)(liu)程部位的(de)(de)安(an)(an)排(pai)如(ru)下所(suo)示：為改進金屬材料的(de)(de)鉆削加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)特性(xing)，如(ru)淬(cui)火、淬(cui)火、熱(re)處(chu)(chu)理(li)(li)(li)等，一般(ban)安(an)(an)排(pai)在(zai)機(ji)械(xie)零(ling)件(jian)(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)前(qian)開展(zhan)。為清除熱(re)應力，如(ru)調(diao)(diao)質處(chu)(chu)理(li)(li)(li)、調(diao)(diao)質熱(re)處(chu)(chu)理(li)(li)(li)等，一般(ban)安(an)(an)排(pai)在(zai)粗(cu)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)以后，精(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)以前(qian)開展(zhan)。為了更好地提升零(ling)件(jian)(jian)的(de)(de)物理(li)(li)(li)性(xing)能，如(ru)滲(shen)氮、熱(re)處(chu)(chu)理(li)(li)(li)、淬(cui)火等，一般(ban)安(an)(an)排(pai)在(zai)機(ji)械(xie)零(ling)件(jian)(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)以后開展(zhan)。如(ru)熱(re)處(chu)(chu)理(li)(li)(li)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)后有很大的(de)(de)形變，還須安(an)(an)排(pai)最后加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)流(liu)(liu)程。
