平面研磨機加工中砂帶出現堵塞

　　平面研(yan)磨(mo)機中(zhong)砂(sha)(sha)帶(dai)(dai)在(zai)進行(xing)研(yan)磨(mo)軟(ruan)質材(cai)料，鋁、銅(tong)以(yi)(yi)及鋁合金(jin)、銅(tong)合金(jin)材(cai)質，加(jia)工(gong)的(de)(de)時(shi)候，比(bi)較容(rong)易出現(xian)(xian)(xian)(xian)(xian)(xian)磨(mo)屑堵塞(sai)砂(sha)(sha)帶(dai)(dai)表面的(de)(de)現(xian)(xian)(xian)(xian)(xian)(xian)象，砂(sha)(sha)帶(dai)(dai)的(de)(de)壽命通常(chang)會(hui)由于磨(mo)粒(li)的(de)(de)脫落而(er)出現(xian)(xian)(xian)(xian)(xian)(xian)結束，由于磨(mo)屑出現(xian)(xian)(xian)(xian)(xian)(xian)堵塞(sai)會(hui)使(shi)整個砂(sha)(sha)帶(dai)(dai)表面出現(xian)(xian)(xian)(xian)(xian)(xian)磨(mo)削(xue)能(neng)力下(xia)(xia)降。磨(mo)粒(li)失掉切(qie)削(xue)效果，砂(sha)(sha)帶(dai)(dai)的(de)(de)接頭會(hui)呈(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)現(xian)(xian)(xian)(xian)(xian)(xian)阻(zu)(zu)塞(sai)而(er)使(shi)外表產(chan)生異(yi)狀(zhuang)波紋，磨(mo)削(xue)力會(hui)以(yi)(yi)接連曲線方式會(hui)呈(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)現(xian)(xian)(xian)(xian)(xian)(xian)下(xia)(xia)降，呈(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)現(xian)(xian)(xian)(xian)(xian)(xian)阻(zu)(zu)塞(sai)也會(hui)以(yi)(yi)緩狀(zhuang)接連的(de)(de)曲線方式呈(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)現(xian)(xian)(xian)(xian)(xian)(xian)。形成這種平面研(yan)磨(mo)機砂(sha)(sha)帶(dai)(dai)呈(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)現(xian)(xian)(xian)(xian)(xian)(xian)阻(zu)(zu)塞(sai)的(de)(de)的(de)(de)主要原因，是因為(wei)磨(mo)削(xue)壓力太大(da)，砂(sha)(sha)帶(dai)(dai)磨(mo)料的(de)(de)挑選不(bu)合適，磨(mo)削(xue)的(de)(de)溫度過(guo)(guo)高，觸摸輪呈(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)現(xian)(xian)(xian)(xian)(xian)(xian)變形過(guo)(guo)大(da)或許(xu)是形狀(zhuang)差錯(cuo)過(guo)(guo)大(da)，會(hui)呈(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)現(xian)(xian)(xian)(xian)(xian)(xian)方位(wei)差異(yi)，以(yi)(yi)及老化(hua)變形，磨(mo)削(xue)用量(liang)的(de)(de)挑選不(bu)妥等多種要素，都會(hui)呈(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)現(xian)(xian)(xian)(xian)(xian)(xian)阻(zu)(zu)塞(sai)的(de)(de)現(xian)(xian)(xian)(xian)(xian)(xian)象，有正常(chang)的(de)(de)阻(zu)(zu)塞(sai)，過(guo)(guo)早(zao)阻(zu)(zu)塞(sai)、縱向部分阻(zu)(zu)塞(sai)、以(yi)(yi)及接頭部分的(de)(de)阻(zu)(zu)塞(sai)，出現(xian)(xian)(xian)(xian)(xian)(xian)阻(zu)(zu)塞(sai)的(de)(de)原因以(yi)(yi)及消除這種阻(zu)(zu)塞(sai)的(de)(de)辦法。

　　1、砂帶接(jie)頭(tou)部分(fen)呈(cheng)現阻(zu)塞(sai)，砂帶的(de)(de)接(jie)頭(tou)厚度(du)(du)超過一(yi)定(ding)外表，有用的(de)(de)研磨(mo)殘存率變小，柔(rou)軟(ruan)度(du)(du)下降(jiang)，都會呈(cheng)現阻(zu)塞(sai)，需求查看其接(jie)頭(tou)的(de)(de)厚度(du)(du)、質量以及接(jie)頭(tou)本身(shen)的(de)(de)柔(rou)軟(ruan)度(du)(du)。

　　2、正常阻塞(sai)，是在平面研磨拋光機加工中呈現的正常阻塞(sai)。

　　3、砂帶呈(cheng)現(xian)縱向部分阻塞，都需求及時的(de)查看修整以(yi)及替換。

　　4、砂帶(dai)的單側呈(cheng)現過早阻塞，主要是因(yin)為與工作臺(tai)的平(ping)行度呈(cheng)現差(cha)異，需求調整(zheng)兩者之間的平(ping)行度;壓(ya)板(ban)的某些部分呈(cheng)現缺點等都(dou)需求查看(kan)、修整(zheng)或(huo)許(xu)及時替換。

　　5、過(guo)早(zao)阻塞的原因有多種(zhong)，平面研磨(mo)拋光機研磨(mo)中(zhong)壓力過(guo)大，需求下(xia)降(jiang)壓力;砂(sha)帶(dai)(dai)的粒度(du)使其壓力過(guo)大，也需求下(xia)降(jiang)研磨(mo)壓力;對加工(gong)(gong)工(gong)(gong)件來(lai)說(shuo)，挑選(xuan)的砂(sha)帶(dai)(dai)粒度(du)不合(he)適(shi)，需求選(xuan)用正確的粒度(du);粘膠的硬度(du)不合(he)適(shi)或許(xu)是呈現老化，需求替(ti)換壓磨(mo)板;砂(sha)帶(dai)(dai)的溫(wen)度(du)過(guo)高(gao)，需求恰當的枯燥，下(xia)降(jiang)砂(sha)帶(dai)(dai)溫(wen)度(du)。
