關于(yu)硬質合金精密加工的介紹(shao)
硬(ying)(ying)(ying)質合金(jin)(jin)是(shi)(shi)一(yi)種(zhong)硬(ying)(ying)(ying)度(du)非常高的(de)材(cai)料，其加(jia)(jia)工過程(cheng)也(ye)是(shi)(shi)有一(yi)定(ding)難(nan)度(du)的(de)。近年來(lai)隨著(zhu)科(ke)技的(de)進步(bu)和生(sheng)產的(de)發展，很(hen)多(duo)工業領域(yu)對硬(ying)(ying)(ying)質合金(jin)(jin)工件(jian)的(de)加(jia)(jia)工要(yao)求越(yue)來(lai)越(yue)高，包括精(jing)密公差(cha)尺寸(cun)和表面粗糙度(du)的(de)高要(yao)求，以(yi)及(ji)一(yi)些堅(jian)硬(ying)(ying)(ying)難(nan)加(jia)(jia)工材(cai)料制成(cheng)的(de)復雜零件(jian)。對硬(ying)(ying)(ying)質合金(jin)(jin)精(jing)密加(jia)(jia)工提出了新(xin)的(de)挑戰。今(jin)天(tian)，西迪小編給大(da)家分享的(de)便(bian)是(shi)(shi)關于硬(ying)(ying)(ying)質合金(jin)(jin)精(jing)密加(jia)(jia)工的(de)相關知識。
硬(ying)質合金精(jing)密(mi)加(jia)(jia)(jia)工(gong)(gong)包(bao)括精(jing)整(zheng)加(jia)(jia)(jia)工(gong)(gong)和光整(zheng)加(jia)(jia)(jia)工(gong)(gong)，精(jing)整(zheng)加(jia)(jia)(jia)工(gong)(gong)是(shi)生產中常(chang)用的(de)(de)精(jing)密(mi)加(jia)(jia)(jia)工(gong)(gong)，指的(de)(de)是(shi)在精(jing)加(jia)(jia)(jia)工(gong)(gong)之后從工(gong)(gong)件上切(qie)除很(hen)薄的(de)(de)材料層(ceng)，以提高工(gong)(gong)件的(de)(de)精(jing)度(du)(du)和減少表面的(de)(de)粗糙(cao)度(du)(du)值為目的(de)(de)的(de)(de)加(jia)(jia)(jia)工(gong)(gong)方(fang)法，如(ru)研磨、珩磨等。而精(jing)密(mi)加(jia)(jia)(jia)工(gong)(gong)的(de)(de)光整(zheng)加(jia)(jia)(jia)工(gong)(gong)是(shi)指不切(qie)除或者從工(gong)(gong)件上切(qie)除極薄材料層(ceng)，以降低表面粗糙(cao)度(du)(du)為目的(de)(de)的(de)(de)加(jia)(jia)(jia)工(gong)(gong)方(fang)法，比(bi)如(ru)超精(jing)加(jia)(jia)(jia)工(gong)(gong)、拋(pao)光等。
硬質合金精密加工的研(yan)磨(mo)是(shi)用(yong)研(yan)磨(mo)工具和研(yan)磨(mo)劑，從工件上研(yan)去一(yi)層極薄表面層的精加工方法。
采用(yong)(yong)不同的(de)研(yan)磨(mo)(mo)(mo)工具，比如(ru)研(yan)磨(mo)(mo)(mo)芯棒、研(yan)磨(mo)(mo)(mo)套(tao)、研(yan)磨(mo)(mo)(mo)平板等(deng)，可對硬質合金(jin)的(de)內(nei)圓、外(wai)圓和(he)平面等(deng)進行研(yan)磨(mo)(mo)(mo)。為了磨(mo)(mo)(mo)料(liao)能嵌入(ru)研(yan)磨(mo)(mo)(mo)套(tao)的(de)內(nei)表面，研(yan)磨(mo)(mo)(mo)套(tao)的(de)材料(liao)應(ying)該軟一些(xie)，常(chang)用(yong)(yong)的(de)是鑄鐵。研(yan)磨(mo)(mo)(mo)時先在(zai)工具表面涂上一層均勻的(de)研(yan)磨(mo)(mo)(mo)劑，手(shou)持(chi)研(yan)磨(mo)(mo)(mo)工具在(zai)軸上來回移(yi)動，直至達到研(yan)磨(mo)(mo)(mo)要(yao)求為止(zhi)。
研磨的(de)精(jing)密(mi)加工方法具有以下特(te)點：
1、 經過(guo)研磨后(hou)的工件表面，尺寸精度(du)(du)可以達到IT4-IT1級(ji)；表面粗(cu)糙度(du)(du)值(zhi)可減小到0.1-0.0006μm。形狀精度(du)(du)可相應提高。
2、 生產效率比較低(di)，加工余量小。
3、 研磨(mo)劑易飛濺，污染環境。
在現代制(zhi)造業中，研磨(mo)應用非常廣，許多(duo)精密量(liang)塊(kuai)、量(liang)規(gui)、齒輪、鋼(gang)球、噴油嘴、石英晶體、陶瓷元件(jian)等零(ling)件(jian)均需(xu)研磨(mo)。
我們再來(lai)看看硬質(zhi)合金精密加工(gong)(gong)(gong)(gong)的(de)另外一(yi)種加工(gong)(gong)(gong)(gong)方(fang)式珩磨(mo)。珩磨(mo)的(de)加工(gong)(gong)(gong)(gong)原理(li)是(shi)利用(yong)珩磨(mo)工(gong)(gong)(gong)(gong)具(ju)對工(gong)(gong)(gong)(gong)件表(biao)面施加一(yi)定壓力(li)，珩磨(mo)工(gong)(gong)(gong)(gong)具(ju)同(tong)時作(zuo)往(wang)復(fu)振動、相對旋轉(zhuan)和直線(xian)往(wang)復(fu)運動，切除(chu)工(gong)(gong)(gong)(gong)件上極小(xiao)的(de)余量的(de)精密加工(gong)(gong)(gong)(gong)方(fang)法。
拋(pao)(pao)光是(shi)利用(yong)(yong)機械、化學或電(dian)化學地作(zuo)用(yong)(yong)，使工(gong)件獲的光亮(liang)、平(ping)整表面的加(jia)(jia)工(gong)方(fang)法(fa)。拋(pao)(pao)光是(shi)安(an)排在工(gong)件精(jing)加(jia)(jia)工(gong)之(zhi)后(hou)進行，拋(pao)(pao)光之(zhi)后(hou)的工(gong)件，粗(cu)糙度(du)(du)R值可達0.1-0.012μm，并能明顯增加(jia)(jia)光亮(liang)度(du)(du)，但是(shi)不能保(bao)持原有的精(jing)度(du)(du)。
硬(ying)質合(he)金精密加(jia)工(gong)(gong)(gong)(gong)(gong)還有很(hen)多加(jia)工(gong)(gong)(gong)(gong)(gong)方式(shi)，如CNC銑(xian)削加(jia)工(gong)(gong)(gong)(gong)(gong)、慢走絲(si)線切割加(jia)工(gong)(gong)(gong)(gong)(gong)、電火花加(jia)工(gong)(gong)(gong)(gong)(gong)、數(shu)控(kong)車床加(jia)工(gong)(gong)(gong)(gong)(gong)等等，今天給大(da)家介紹的(de)還只是(shi)磨(mo)加(jia)工(gong)(gong)(gong)(gong)(gong)的(de)一小(xiao)部(bu)分，硬(ying)質合(he)金精密加(jia)工(gong)(gong)(gong)(gong)(gong)是(shi)一門大(da)學問，公司在(zai)硬(ying)質合(he)金精密加(jia)工(gong)(gong)(gong)(gong)(gong)方面(mian)擁(yong)有非常雄(xiong)厚(hou)的(de)實力(li)，配備各(ge)類(lei)先進加(jia)工(gong)(gong)(gong)(gong)(gong)設備，適用于(yu)各(ge)類(lei)高精密、特種(zhong)材料、偏心內外形、彎頭、復雜(za)幾何(he)零件的(de)加(jia)工(gong)(gong)(gong)(gong)(gong)，歡迎(ying)前來咨詢。
