無心磨(mo)也叫無心磨(mo)削(xue),是磨(mo)削(xue)生產加工(gong)的一種(zhong)。有導輪(lun)和(he)磨(mo)削(xue)輪(lun)兩(liang)個砂輪(lun),導輪(lun)促(cu)進圓柱狀工(gong)件在(zai)保護層墊塊上轉動,磨(mo)削(xue)輪(lun)對工(gong)件起磨(mo)削(xue)作(zuo)用(yong)。無心磨(mo)屬于(yu)周磨(mo)法。
不經意研削法它是由(you)磨削砂輪(lun),調(diao)(diao)整輪(lun)和(he)工(gong)件(jian)(jian)(jian)固(gu)定支架(固(gu)定支架)三個機構(gou)構(gou)成(cheng),在這其(qi)中磨削砂輪(lun)實際擔(dan)任磨削的工(gong)作(zuo)上,調(diao)(diao)整輪(lun)控制工(gong)件(jian)(jian)(jian)的旋轉(zhuan),并(bing)使工(gong)件(jian)(jian)(jian)造成(cheng)下刀速度,針對工(gong)件(jian)(jian)(jian)固(gu)定支架乃(nai)在磨削時(shi)支點(dian)工(gong)件(jian)(jian)(jian),這三種零(ling)件(jian)(jian)(jian)可有多種多樣互相配合的方法,但停止研磨之外,基本概念上邊(bian)一樣。
