無心磨的加工方式介紹

無心磨(mo)床,是無需(xu)采用工(gong)(gong)件(jian)的(de)(de)樞軸準(zhun)確定(ding)位而(er)進(jin)行磨(mo)削(xue)的(de)(de)一(yi)(yi)類數控磨(mo)床,重要由磨(mo)削(xue)沙輪(lun)片(pian)、調整(zheng)輪(lun)和工(gong)(gong)件(jian)固(gu)定(ding)支(zhi)(zhi)架三個機構(gou)(gou)構(gou)(gou)成,在(zai)這其中(zhong)磨(mo)削(xue)沙輪(lun)片(pian)實際(ji)擔任磨(mo)削(xue)的(de)(de)工(gong)(gong)作上(shang),調整(zheng)輪(lun)控制工(gong)(gong)件(jian)的(de)(de)旋轉,并控制工(gong)(gong)件(jian)的(de)(de)進(jin)刀速度,針對(dui)工(gong)(gong)件(jian)固(gu)定(ding)支(zhi)(zhi)架乃在(zai)磨(mo)削(xue)時(shi)支(zhi)(zhi)點(dian)工(gong)(gong)件(jian),這三種(zhong)零(ling)件(jian)可有多種(zhong)多樣(yang)(yang)互相配合的(de)(de)方(fang)法,但(dan)停止(zhi)研磨(mo)之外(wai),基本(ben)概念上(shang)邊一(yi)(yi)樣(yang)(yang)。

無心磨(mo)(mo)(mo)床重要有(you)(you)三種磨(mo)(mo)(mo)削(xue)方法;依據(ju)式(shi)(shi)、切(qie)入式(shi)(shi)和切(qie)入一(yi)依據(ju)式(shi)(shi)、依據(ju)式(shi)(shi)不經意(yi)(yi)磨(mo)(mo)(mo)削(xue)。工(gong)(gong)件沿沙輪片(pian)軸線(xian)方向進(jin)刀(dao)(dao)進(jin)行(xing)磨(mo)(mo)(mo)削(xue)。調整導(dao)輪軸線(xian)的(de)(de)微小傾(qing)角(jiao)來進(jin)行(xing)工(gong)(gong)件軸頸走刀(dao)(dao)。合適磨(mo)(mo)(mo)削(xue)長細(xi)圓柱狀工(gong)(gong)件。無管理處孔的(de)(de)短軸和軸類(lei)零件生產(chan)加(jia)工(gong)(gong)工(gong)(gong)件等。切(qie)入式(shi)(shi)不經意(yi)(yi)磨(mo)(mo)(mo)削(xue)。墊(dian)塊(kuai)上(shang)邊(bian)有(you)(you)軸頸準確定(ding)位(wei)支點,工(gong)(gong)件支撐點在墊(dian)塊(kuai)一(yi)定(ding)位(wei)置(zhi)上(shang),以沙輪片(pian)或(huo)導(dao)輪切(qie)入進(jin)行(xing)磨(mo)(mo)(mo)削(xue)。用于磨(mo)(mo)(mo)削(xue)帶(dai)軸環或(huo)模座的(de)(de)工(gong)(gong)件以及(ji)圓錐體(ti),球體(ti)或(huo)其他旋轉體(ti)工(gong)(gong)件。切(qie)入一(yi)依據(ju)式(shi)(shi)不經意(yi)(yi)磨(mo)(mo)(mo)削(xue)是這二者的(de)(de)復(fu)合性。此外,也(ye)是有(you)(you)斷開走刀(dao)(dao)片(pian)式(shi)(shi)磨(mo)(mo)(mo)削(xue)和使帶(dai)臺階的(de)(de)工(gong)(gong)件在軸頸進(jin)、退的(de)(de)內螺紋走刀(dao)(dao)片(pian)式(shi)(shi)磨(mo)(mo)(mo)削(xue)。無心磨(mo)(mo)(mo)床生產(chan)率(lv)較高。多用于許多生產(chan)加(jia)工(gong)(gong),有(you)(you)利于進(jin)行(xing)自動化控(kong)制(zhi)。
