無心磨也(ye)叫無心磨削(xue)(xue),是(shi)磨削(xue)(xue)生產加工(gong)的一種。有導(dao)輪和(he)磨削(xue)(xue)輪2個砂輪,導(dao)輪推動圓柱型(xing)工(gong)件在墊塊上旋(xuan)轉,磨削(xue)(xue)輪對(dui)工(gong)件起磨削(xue)(xue)功(gong)效。無心磨歸屬于(yu)周磨法。
基本原理
無意(yi)研(yan)削(xue)(xue)法它是由磨(mo)(mo)削(xue)(xue)砂輪(lun),調(diao)節(jie)輪(lun)和工件支撐架(托架)三(san)個組(zu)(zu)織組(zu)(zu)成,在其中磨(mo)(mo)削(xue)(xue)砂輪(lun)具體出任磨(mo)(mo)削(xue)(xue)的工作中,調(diao)節(jie)輪(lun)操縱(zong)工件的轉動,并使工件產(chan)生下(xia)刀速率,對(dui)于工件支撐架乃(nai)在磨(mo)(mo)削(xue)(xue)時支撐點工件,這三(san)種零件可有多種相互(hu)配合的方式,但(dan)終止碾磨(mo)(mo)以外(wai),基本原理上面同(tong)樣。
無心磨砂輪(lun)是(shi)安裝在(zai)無心磨床邊應用(yong)的(de)(de)(de)一款(kuan)砂輪(lun),它與導(dao)輪(lun)、墊(dian)板(ban)相互影響,構成(cheng)的(de)(de)(de)一種磨削(xue)方(fang)法,被生產(chan)(chan)(chan)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)經墊(dian)板(ban)托(tuo)著,由導(dao)輪(lun)向墊(dian)板(ban)方(fang)位勻速圓周運動而推動工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)轉動時(shi)由無意砂輪(lun)磨削(xue),在(zai)磨削(xue)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)時(shi)工(gong)(gong)(gong)(gong)(gong)藝性能較高,精(jing)密度(du)(du)(du)(du)相對(dui)性也(ye)很高,磨削(xue)中,挑(tiao)(tiao)選(xuan)砂輪(lun)粒(li)(li)度(du)(du)(du)(du)分(fen)布也(ye)非(fei)常關鍵,細粒(li)(li)度(du)(du)(du)(du)的(de)(de)(de)無心磨砂輪(lun)通常用(yong)以(yi)精(jing)磨生產(chan)(chan)(chan)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong),只有生產(chan)(chan)(chan)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)規定(ding)算不上(shang)高的(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian),一般在(zai)生產(chan)(chan)(chan)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)時(shi)為(wei)了(le)更好(hao)地加(jia)(jia)速磨削(xue)速率,對(dui)產(chan)(chan)(chan)量很大的(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)一道生產(chan)(chan)(chan)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)都(dou)是(shi)會選(xuan)用(yong)這(zhe)類(lei)(lei)方(fang)式,它是(shi)因(yin)為(wei)它生產(chan)(chan)(chan)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)速率較為(wei)快的(de)(de)(de)特性,但(dan)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)的(de)(de)(de)光滑度(du)(du)(du)(du)較低(di)。而粗粒(li)(li)度(du)(du)(du)(du)的(de)(de)(de)無心磨砂輪(lun)生產(chan)(chan)(chan)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)品質精(jing)密度(du)(du)(du)(du)則反過來,其生產(chan)(chan)(chan)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)速率偏慢,但(dan)被生產(chan)(chan)(chan)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)光滑度(du)(du)(du)(du)高,如挑(tiao)(tiao)選(xuan)的(de)(de)(de)粒(li)(li)度(du)(du)(du)(du)分(fen)布適度(du)(du)(du)(du)可做到鏡面玻璃實際效果,因(yin)而,挑(tiao)(tiao)選(xuan)無心磨砂輪(lun)是(shi)要(yao)依據工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)的(de)(de)(de)技術性加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝規定(ding)實際開展挑(tiao)(tiao)選(xuan)。在(zai)其中也(ye)包含砂輪(lun)的(de)(de)(de)強度(du)(du)(du)(du)、機構相對(dui)密度(du)(du)(du)(du),粒(li)(li)度(du)(du)(du)(du)分(fen)布的(de)(de)(de)挑(tiao)(tiao)選(xuan)。磨削(xue)不一樣(yang)的(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian),挑(tiao)(tiao)選(xuan)的(de)(de)(de)切削(xue)油也(ye)不盡(jin)相同。一般的(de)(de)(de)鐵制,大家只要(yao)用(yong)一般的(de)(de)(de)切削(xue)油,而磨鋁類(lei)(lei)軟塑零件(jian)(jian)(jian)時(shi)必須用(yong)汽(qi)油來冷切。
