雞眼機偏心軸頭加工(gong)注意哪些方面

　　1.一般來說，工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)端(duan)面(mian)(mian)的(de)(de)零件(jian)(jian)(jian)(jian)是(shi)圓(yuan)盤(pan)零件(jian)(jian)(jian)(jian)，或圓(yuan)筒零件(jian)(jian)(jian)(jian)、輪(lun)轂零件(jian)(jian)(jian)(jian)等。這些零件(jian)(jian)(jian)(jian)夾(jia)緊在卡盤(pan)上(shang)，工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)的(de)(de)外(wai)圓(yuan)和(he)端(duan)面(mian)(mian)用(yong)劃針板修正。在加工(gong)(gong)(gong)(gong)某些細(xi)長(chang)圓(yuan)柱體或軸(zhou)端(duan)面(mian)(mian)零件(jian)(jian)(jian)(jian)時(shi)，夾(jia)緊工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)應注意工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)的(de)(de)夾(jia)緊部分應縮短，否則，工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)的(de)(de)伸(shen)長(chang)過長(chang)，會使車床工(gong)(gong)(gong)(gong)具(ju)(ju)升降斷裂。圖(tu)2。各(ge)種車削(xue)(xue)(xue)(xue)(xue)方法與右側刀(dao)(dao)具(ju)(ju)面(mian)(mian)1。使用(yong)右側的(de)(de)刀(dao)(dao)面(mian)(mian)，一般適用(yong)于(yu)(yu)帶有工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)的(de)(de)步進車削(xue)(xue)(xue)(xue)(xue)。因(yin)為在一般情況下，由(you)外(wai)向中心進給，是(shi)用(yong)切(qie)(qie)(qie)(qie)(qie)(qie)削(xue)(xue)(xue)(xue)(xue)刃(ren)切(qie)(qie)(qie)(qie)(qie)(qie)削(xue)(xue)(xue)(xue)(xue)，切(qie)(qie)(qie)(qie)(qie)(qie)削(xue)(xue)(xue)(xue)(xue)不光(guang)滑，并且容(rong)易出(chu)現“刀(dao)(dao)刃(ren)”.有時(shi)前角是(shi)分切(qie)(qie)(qie)(qie)(qie)(qie)削(xue)(xue)(xue)(xue)(xue)刀(dao)(dao)片(pian)在地(di)面(mian)(mian)上(shang)與主切(qie)(qie)(qie)(qie)(qie)(qie)削(xue)(xue)(xue)(xue)(xue)刀(dao)(dao)片(pian)旋轉(zhuan)的(de)(de)角度(du)(du)。45.回轉(zhuan)工(gong)(gong)(gong)(gong)作(zuo)面(mian)(mian)。45號在右邊。車刀(dao)(dao)使用(yong)主切(qie)(qie)(qie)(qie)(qie)(qie)削(xue)(xue)(xue)(xue)(xue)刃(ren)進行切(qie)(qie)(qie)(qie)(qie)(qie)削(xue)(xue)(xue)(xue)(xue)。前角在刀(dao)(dao)刃(ren)上(shang)磨削(xue)(xue)(xue)(xue)(xue)，切(qie)(qie)(qie)(qie)(qie)(qie)削(xue)(xue)(xue)(xue)(xue)平穩，工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)表(biao)面(mian)(mian)粗(cu)糙度(du)(du)。45.車刀(dao)(dao)的(de)(de)刀(dao)(dao)尖角等于(yu)(yu)90。刀(dao)(dao)尖的(de)(de)強度(du)(du)高(gao)于(yu)(yu)偏置刀(dao)(dao)具(ju)(ju)的(de)(de)強度(du)(du)。適用(yong)于(yu)(yu)端(duan)面(mian)(mian)和(he)倒(dao)角的(de)(de)圓(yuan)柱形工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)的(de)(de)車削(xue)(xue)(xue)(xue)(xue)。圖(tu)3。用(yong)你的(de)(de)左手(shou)移動你的(de)(de)臉。左手(shou)工(gong)(gong)(gong)(gong)具(ju)(ju)使用(yong)主切(qie)(qie)(qie)(qie)(qie)(qie)削(xue)(xue)(xue)(xue)(xue)刃(ren)進行切(qie)(qie)(qie)(qie)(qie)(qie)削(xue)(xue)(xue)(xue)(xue)，因(yin)此切(qie)(qie)(qie)(qie)(qie)(qie)削(xue)(xue)(xue)(xue)(xue)是(shi)平滑的(de)(de)，表(biao)面(mian)(mian)粗(cu)糙度(du)(du)是(shi)旋轉(zhuan)的(de)(de)，但刀(dao)(dao)尖角小于(yu)(yu)90。是(shi)的(de)(de)，這條(tiao)線索(suo)的(de)(de)強度(du)(du)是(shi)45。刀(dao)(dao)具(ju)(ju)誤差。

　　粗加工(gong) ap = 2ー5mm，精加工(gong) ap = 0.5ー1mm。進給速度(du)。粗加工(gong)時間，精加工(gong)時間，切削(xue)速度(du)。車(che)床(chuang)端(duan)(duan)面的(de)切削(xue)速度(du)隨著工(gong)件直徑(jing)的(de)減(jian)小而減(jian)小，但應(ying)根據大(da)直徑(jing)計算。檢驗方法(fa)(fa)上，末(mo)端(duan)(duan)最主要的(de)要求是平、刀線。一般精度(du)的(de)工(gong)件可用(yong)鋼尺(chi)檢查(cha)。對于精度(du)較高(gao)的(de)工(gong)件端(duan)(duan)面，應(ying)采(cai)用(yong)光傳動檢驗用(yong)刀口尺(chi)。方法(fa)(fa)和(he)鋼尺(chi)一樣。
