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)加(jia)(jia)(jia)工(gong)(gong)(gong)為了更(geng)好地確保機(ji)器設備(bei)零(ling)(ling)(ling)件(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)度(du)(du)(du)，粗、精(jing)機(ji)械(xie)(xie)零(ling)(ling)(ling)件(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)更(geng)好是分(fen)離開(kai)展(zhan)。由(you)于(yu)粗機(ji)械(xie)(xie)零(ling)(ling)(ling)件(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)時(shi)，鉆削(xue)(xue)量大(da)，產品工(gong)(gong)(gong)件(jian)所受(shou)切削(xue)(xue)速(su)度(du)(du)(du)、夾(jia)持(chi)力(li)大(da)，熱(re)(re)值多，及其機(ji)械(xie)(xie)零(ling)(ling)(ling)件(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)表層有較明顯的加(jia)(jia)(jia)工(gong)(gong)(gong)硬底化狀(zhuang)況(kuang)，產品工(gong)(gong)(gong)件(jian)內(nei)部具有著很大(da)的熱(re)(re)應(ying)力(li)，假如粗、粗機(ji)械(xie)(xie)零(ling)(ling)(ling)件(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)持(chi)續(xu)開(kai)展(zhan)，則精(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)后的零(ling)(ling)(ling)件(jian)精(jing)度(du)(du)(du)會由(you)于(yu)壓力(li)的再次劃分(fen)而(er)迅速(su)缺失。針對一(yi)些機(ji)械(xie)(xie)零(ling)(ling)(ling)件(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)度(du)(du)(du)規定高的零(ling)(ling)(ling)件(jian)。在粗加(jia)(jia)(jia)工(gong)(gong)(gong)以后和(he)精(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)以前，還應(ying)安排超(chao)低溫淬火或固溶處理(li)步驟來清(qing)除熱(re)(re)應(ying)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、精密五金零件加(jia)(jia)工(gong)(gong)(gong)(gong)在機器(qi)設(she)備零件加(jia)(jia)工(gong)(gong)(gong)(gong)加(jia)(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝(yi)風格中，常(chang)安(an)排(pai)(pai)有(you)(you)熱(re)(re)處(chu)(chu)(chu)(chu)理工(gong)(gong)(gong)(gong)藝(yi)工(gong)(gong)(gong)(gong)藝(yi)流(liu)(liu)程。熱(re)(re)處(chu)(chu)(chu)(chu)理工(gong)(gong)(gong)(gong)藝(yi)工(gong)(gong)(gong)(gong)藝(yi)流(liu)(liu)程部(bu)位(wei)的安(an)排(pai)(pai)如(ru)下所示：為改(gai)進(jin)金屬材料(liao)的鉆削加(jia)(jia)工(gong)(gong)(gong)(gong)特(te)性，如(ru)淬火、淬火、熱(re)(re)處(chu)(chu)(chu)(chu)理等(deng)，一(yi)般(ban)安(an)排(pai)(pai)在機械(xie)零件加(jia)(jia)工(gong)(gong)(gong)(gong)前開(kai)展。為清除(chu)熱(re)(re)應力，如(ru)調質(zhi)處(chu)(chu)(chu)(chu)理、調質(zhi)熱(re)(re)處(chu)(chu)(chu)(chu)理等(deng)，一(yi)般(ban)安(an)排(pai)(pai)在粗加(jia)(jia)工(gong)(gong)(gong)(gong)以(yi)(yi)后(hou)，精加(jia)(jia)工(gong)(gong)(gong)(gong)以(yi)(yi)前開(kai)展。為了(le)更好地提升零件的物(wu)理性能，如(ru)滲(shen)氮、熱(re)(re)處(chu)(chu)(chu)(chu)理、淬火等(deng)，一(yi)般(ban)安(an)排(pai)(pai)在機械(xie)零件加(jia)(jia)工(gong)(gong)(gong)(gong)以(yi)(yi)后(hou)開(kai)展。如(ru)熱(re)(re)處(chu)(chu)(chu)(chu)理工(gong)(gong)(gong)(gong)藝(yi)后(hou)有(you)(you)很大的形變，還(huan)須安(an)排(pai)(pai)最后(hou)加(jia)(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝(yi)流(liu)(liu)程。
