磨床通常(chang)是用(yong)于磨削(xue)的(de)(de)動(dong)力工(gong)具設備(bei)或(huo)機床。與其他機床一(yi)樣(yang)，這(zhe)是一(yi)種使用(yong)砂(sha)輪(lun)作為切削(xue)工(gong)具的(de)(de)加(jia)工(gong)設備(bei)。磨床作為一(yi)類工(gong)業(ye)動(dong)力加(jia)工(gong)的(de)(de)設備(bei)，其特征在于砂(sha)輪(lun)用(yong)于從(cong)金屬表(biao)面切割或(huo)去除切屑。也可以(yi)定(ding)義為通過使用(yong)旋轉的(de)(de)砂(sha)輪(lun)從(cong)工(gong)件表(biao)面進行(xing)金屬切削(xue)的(de)(de)過程。
磨(mo)(mo)(mo)(mo)床(chuang)(chuang)(chuang)種類(lei)較多有外圓(yuan)磨(mo)(mo)(mo)(mo)床(chuang)(chuang)(chuang)、內圓(yuan)磨(mo)(mo)(mo)(mo)床(chuang)(chuang)(chuang)、無心磨(mo)(mo)(mo)(mo)床(chuang)(chuang)(chuang)、平面磨(mo)(mo)(mo)(mo)床(chuang)(chuang)(chuang)等類(lei)型，這里我(wo)們主要介紹外圓(yuan)磨(mo)(mo)(mo)(mo)床(chuang)(chuang)(chuang)和(he)無心磨(mo)(mo)(mo)(mo)床(chuang)(chuang)(chuang)的區別。無心磨(mo)(mo)(mo)(mo)床(chuang)(chuang)(chuang)加(jia)工(gong)(gong)效率(lv)高，可以一(yi)次加(jia)工(gong)(gong)多件零(ling)件，外圓(yuan)磨(mo)(mo)(mo)(mo)床(chuang)(chuang)(chuang)加(jia)工(gong)(gong)產品需要少量，但是外圓(yuan)磨(mo)(mo)(mo)(mo)床(chuang)(chuang)(chuang)適合磨(mo)(mo)(mo)(mo)削較大較長的工(gong)(gong)件，且精度也較為(wei)精準，不過各(ge)有特點。下(xia)面，我(wo)們就來介紹無心磨(mo)(mo)(mo)(mo)床(chuang)(chuang)(chuang)與外圓(yuan)磨(mo)(mo)(mo)(mo)床(chuang)(chuang)(chuang)的區別。
無心磨床(chuang)與外圓磨床(chuang)的區(qu)別
1、磨(mo)(mo)(mo)削(xue)(xue)原理(li)：在外(wai)圓(yuan)(yuan)磨(mo)(mo)(mo)床(chuang)上進(jin)行磨(mo)(mo)(mo)削(xue)(xue)加工(gong)時，是用以磨(mo)(mo)(mo)削(xue)(xue)軸(zhou)類工(gong)件(jian)的(de)外(wai)圓(yuan)(yuan)柱、外(wai)圓(yuan)(yuan)錐和(he)軸(zhou)肩端面。無心磨(mo)(mo)(mo)床(chuang)磨(mo)(mo)(mo)削(xue)(xue)加工(gong)時，有導輪(lun)和(he)磨(mo)(mo)(mo)削(xue)(xue)輪(lun)兩個砂輪(lun)，導輪(lun)帶(dai)動圓(yuan)(yuan)柱形(xing)工(gong)件(jian)在墊鐵上轉動，磨(mo)(mo)(mo)削(xue)(xue)輪(lun)對工(gong)件(jian)起到(dao)磨(mo)(mo)(mo)削(xue)(xue)作用。
2、加工精(jing)度(du)：無心磨(mo)床(chuang)和外圓磨(mo)床(chuang)這兩(liang)類(lei)磨(mo)床(chuang)要(yao)(yao)比(bi)精(jing)度(du)的話應該不能隨意定論，兩(liang)種磨(mo)床(chuang)都很精(jing)密，主(zhu)要(yao)(yao)還得看磨(mo)床(chuang)的產(chan)地(di)和制造精(jing)度(du)，無心磨(mo)主(zhu)要(yao)(yao)針對批量的軸類(lei)產(chan)品加工，是(shi)由(you)砂輪和導論的互相擠壓(ya)磨(mo)削，零(ling)件(jian)(jian)轉(zhuan)動時沒有(you)固定旋轉(zhuan)中心，而外圓磨(mo)需要(yao)(yao)頂針固定零(ling)件(jian)(jian)，使它有(you)繞軸心旋轉(zhuan)磨(mo)削。
3、加(jia)工(gong)(gong)(gong)(gong)方(fang)式：外(wai)(wai)圓(yuan)(yuan)(yuan)磨(mo)(mo)床(chuang)(chuang)(chuang)的(de)(de)工(gong)(gong)(gong)(gong)件(jian)加(jia)工(gong)(gong)(gong)(gong)時(shi)是要(yao)定(ding)(ding)心的(de)(de)，用頭(tou)尾(wei)架(jia)頂尖定(ding)(ding)心或用卡盤(pan)定(ding)(ding)心裝夾等(deng)等(deng)。無心磨(mo)(mo)床(chuang)(chuang)(chuang)是依靠外(wai)(wai)圓(yuan)(yuan)(yuan)自旋轉加(jia)工(gong)(gong)(gong)(gong)，由于不能(neng)定(ding)(ding)心加(jia)工(gong)(gong)(gong)(gong)其圓(yuan)(yuan)(yuan)度(du)(du)取(qu)決于工(gong)(gong)(gong)(gong)件(jian)本身的(de)(de)圓(yuan)(yuan)(yuan)度(du)(du)，所(suo)以(yi)加(jia)工(gong)(gong)(gong)(gong)成圓(yuan)(yuan)(yuan)的(de)(de)精度(du)(du)不如(ru)外(wai)(wai)圓(yuan)(yuan)(yuan)磨(mo)(mo)床(chuang)(chuang)(chuang)，所(suo)以(yi)圓(yuan)(yuan)(yuan)度(du)(du)要(yao)求高一些的(de)(de)工(gong)(gong)(gong)(gong)件(jian)上(shang)(shang)無心磨(mo)(mo)床(chuang)(chuang)(chuang)加(jia)工(gong)(gong)(gong)(gong)前先用外(wai)(wai)圓(yuan)(yuan)(yuan)磨(mo)(mo)加(jia)工(gong)(gong)(gong)(gong)圓(yuan)(yuan)(yuan)后再上(shang)(shang)無心磨(mo)(mo)床(chuang)(chuang)(chuang)會好(hao)很(hen)多。
4、工件(jian)同(tong)心(xin)(xin)度：無(wu)心(xin)(xin)磨床(chuang)與外(wai)圓(yuan)磨床(chuang)同(tong)樣是研磨外(wai)圓(yuan)，而(er)外(wai)圓(yuan)磨床(chuang)能(neng)保證(zheng)工件(jian)的(de)同(tong)心(xin)(xin)度，而(er)無(wu)心(xin)(xin)磨床(chuang)在一般情況下是不能(neng)保證(zheng)工件(jian)的(de)同(tong)心(xin)(xin)度要求。
5、磨床用(yong)途(tu)：外圓(yuan)(yuan)磨床主要用(yong)于(yu)成批(pi)軸(zhou)類零件的(de)端面(mian)、外圓(yuan)(yuan)及圓(yuan)(yuan)錐面(mian)的(de)精(jing)密(mi)磨削，是適(shi)用(yong)于(yu)軍工(gong)、航(hang)天、一般精(jing)密(mi)機(ji)械加工(gong)車間批(pi)量較(jiao)小(xiao)，精(jing)度要求較(jiao)高(gao)的(de)軸(zhou)類零件加工(gong)。無心磨床主要適(shi)用(yong)范圍：用(yong)來(lai)對各種圈類、軸(zhou)類及管(guan)類零件的(de)圓(yuan)(yuan)柱(zhu)面(mian)進(jin)行通(tong)拋(pao)光。對各種階梯、錐形(xing)，無心磨床主要用(yong)于(yu)各種圓(yuan)(yuan)柱(zhu)零件、環形(xing)零件進(jin)行通(tong)磨磨削，以及對圓(yuan)(yuan)錐體零件的(de)切(qie)入磨削等。
6、磨床(chuang)結構：外圓磨床(chuang)由(you)床(chuang)身與工(gong)作臺、砂輪(lun)架(jia)、頭(tou)架(jia)、磨架(jia)、縱向(xiang)(xiang)進給手(shou)輪(lun)、橫向(xiang)(xiang)進給手(shou)輪(lun)、換向(xiang)(xiang)擋(dang)板(ban)等等部件構成。而(er)無心磨床(chuang)主要是(shi)由(you)機身、砂輪(lun)架(jia)、導輪(lun)、頭(tou)架(jia)、主軸單元式結構、主軸拉桿自動(dong)裝刀系統等部件組成。
7、磨(mo)床特點：外(wai)圓(yuan)磨(mo)床的砂輪主軸(zhou)軸(zhou)承采用錐形成型油(you)楔動*承、砂輪主軸(zhou)在低速(su)是(shi)仍具有高(gao)的軸(zhou)承剛度(du)。無心磨(mo)床其主要(yao)特點為通用性好、模塊程度(du)化高(gao)、精度(du)和(he)剛性高(gao)，以及無心磨(mo)床的工作效(xiao)率(lv)高(gao)。
無心(xin)磨床與外(wai)圓磨床較大的區別就是無心(xin)磨可(ke)以不用夾(jia)具，只(zhi)用刀板承(cheng)托(tuo)工(gong)件(jian)(jian)，還多一只(zhi)導輪帶動工(gong)件(jian)(jian)磨削，不過外(wai)圓磨不用刀板就要用頂(ding)尖和夾(jia)具來裝夾(jia)工(gong)件(jian)(jian)磨削，外(wai)圓磨床只(zhi)裝砂輪而不需導輪。
本文介紹了無心(xin)磨(mo)(mo)(mo)床與外(wai)圓(yuan)(yuan)磨(mo)(mo)(mo)床的(de)共同點與區別(bie)，同樣是磨(mo)(mo)(mo)床設備的(de)無心(xin)磨(mo)(mo)(mo)床和(he)外(wai)圓(yuan)(yuan)磨(mo)(mo)(mo)床都采用砂輪(lun)進行磨(mo)(mo)(mo)削加(jia)工(gong)操作，不過(guo)也是有較大(da)的(de)各類工(gong)件(jian)加(jia)工(gong)上區別(bie)，無心(xin)磨(mo)(mo)(mo)適(shi)合批(pi)量的(de)生產，外(wai)圓(yuan)(yuan)磨(mo)(mo)(mo)適(shi)合高精密的(de)單件(jian)加(jia)工(gong)。關(guan)注我們百家(jia)號，了解更(geng)多關(guan)于磨(mo)(mo)(mo)床的(de)知識和(he)案(an)例。
