關于(yu)硬(ying)質(zhi)合金精密加工(gong)的介紹
硬(ying)質(zhi)合金是一種硬(ying)度(du)非(fei)常高的(de)材料，其加(jia)(jia)工(gong)(gong)(gong)過程也(ye)是有一定難(nan)度(du)的(de)。近年(nian)來(lai)隨著科(ke)技的(de)進步(bu)和(he)生(sheng)產(chan)的(de)發展，很多工(gong)(gong)(gong)業領(ling)域對硬(ying)質(zhi)合金工(gong)(gong)(gong)件的(de)加(jia)(jia)工(gong)(gong)(gong)要求越(yue)(yue)來(lai)越(yue)(yue)高，包括精密公差(cha)尺(chi)寸和(he)表面(mian)粗糙(cao)度(du)的(de)高要求，以及(ji)一些堅硬(ying)難(nan)加(jia)(jia)工(gong)(gong)(gong)材料制成(cheng)的(de)復雜零件。對硬(ying)質(zhi)合金精密加(jia)(jia)工(gong)(gong)(gong)提出了(le)新的(de)挑(tiao)戰。今天，西迪(di)小(xiao)編給大(da)家分享的(de)便是關于硬(ying)質(zhi)合金精密加(jia)(jia)工(gong)(gong)(gong)的(de)相關知識。
硬質合金精(jing)(jing)密加(jia)(jia)工(gong)(gong)(gong)(gong)包括精(jing)(jing)整(zheng)加(jia)(jia)工(gong)(gong)(gong)(gong)和光(guang)整(zheng)加(jia)(jia)工(gong)(gong)(gong)(gong)，精(jing)(jing)整(zheng)加(jia)(jia)工(gong)(gong)(gong)(gong)是(shi)生產中(zhong)常用的(de)(de)(de)精(jing)(jing)密加(jia)(jia)工(gong)(gong)(gong)(gong)，指(zhi)的(de)(de)(de)是(shi)在精(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)之后從工(gong)(gong)(gong)(gong)件(jian)上切(qie)除很(hen)薄(bo)的(de)(de)(de)材料層(ceng)(ceng)，以(yi)提高工(gong)(gong)(gong)(gong)件(jian)的(de)(de)(de)精(jing)(jing)度(du)和減少表面的(de)(de)(de)粗(cu)糙度(du)值為目的(de)(de)(de)的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)方法，如研磨(mo)(mo)、珩磨(mo)(mo)等(deng)。而(er)精(jing)(jing)密加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)光(guang)整(zheng)加(jia)(jia)工(gong)(gong)(gong)(gong)是(shi)指(zhi)不切(qie)除或者從工(gong)(gong)(gong)(gong)件(jian)上切(qie)除極薄(bo)材料層(ceng)(ceng)，以(yi)降(jiang)低表面粗(cu)糙度(du)為目的(de)(de)(de)的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)方法，比如超精(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)、拋(pao)光(guang)等(deng)。
硬質(zhi)合金精(jing)密(mi)加(jia)工(gong)(gong)的(de)研(yan)磨是(shi)用研(yan)磨工(gong)(gong)具(ju)和研(yan)磨劑，從工(gong)(gong)件上研(yan)去一層極(ji)薄表面層的(de)精(jing)加(jia)工(gong)(gong)方法。
采用(yong)不(bu)同的(de)研磨(mo)(mo)(mo)(mo)(mo)工(gong)具(ju)，比如研磨(mo)(mo)(mo)(mo)(mo)芯(xin)棒、研磨(mo)(mo)(mo)(mo)(mo)套、研磨(mo)(mo)(mo)(mo)(mo)平板(ban)等，可對硬質(zhi)合金的(de)內圓、外圓和平面等進行研磨(mo)(mo)(mo)(mo)(mo)。為了磨(mo)(mo)(mo)(mo)(mo)料能嵌入研磨(mo)(mo)(mo)(mo)(mo)套的(de)內表面，研磨(mo)(mo)(mo)(mo)(mo)套的(de)材(cai)料應(ying)該軟一(yi)些，常用(yong)的(de)是(shi)鑄鐵。研磨(mo)(mo)(mo)(mo)(mo)時先在工(gong)具(ju)表面涂上一(yi)層均勻的(de)研磨(mo)(mo)(mo)(mo)(mo)劑，手持(chi)研磨(mo)(mo)(mo)(mo)(mo)工(gong)具(ju)在軸上來回移動，直至達到研磨(mo)(mo)(mo)(mo)(mo)要(yao)求為止。
研磨的精(jing)密加工方法具(ju)有以下特(te)點(dian)：
1、 經(jing)過研磨(mo)后的工件表面，尺(chi)寸精(jing)度可(ke)(ke)以(yi)達到IT4-IT1級(ji)；表面粗糙度值可(ke)(ke)減小到0.1-0.0006μm。形狀精(jing)度可(ke)(ke)相應提高。
2、 生產(chan)效率比較低，加工余量小。
3、 研磨劑易飛濺，污染環境。
在(zai)現(xian)代制造(zao)業(ye)中，研磨應用非常廣(guang)，許多精密(mi)量(liang)塊、量(liang)規(gui)、齒輪、鋼球、噴油嘴、石英(ying)晶體、陶瓷元(yuan)件等零件均需研磨。
我們(men)再來看看硬質合金(jin)精密(mi)加(jia)(jia)工的(de)(de)另外一種加(jia)(jia)工方式珩(heng)(heng)磨(mo)(mo)。珩(heng)(heng)磨(mo)(mo)的(de)(de)加(jia)(jia)工原(yuan)理是(shi)利(li)用珩(heng)(heng)磨(mo)(mo)工具(ju)對工件表(biao)面施加(jia)(jia)一定壓(ya)力(li)，珩(heng)(heng)磨(mo)(mo)工具(ju)同(tong)時(shi)作往復振(zhen)動(dong)、相對旋(xuan)轉(zhuan)和直線(xian)往復運動(dong)，切除工件上極小的(de)(de)余(yu)量的(de)(de)精密(mi)加(jia)(jia)工方法。
拋(pao)光(guang)(guang)是(shi)(shi)利(li)用機械、化(hua)學或電化(hua)學地(di)作用，使工(gong)件獲的(de)(de)光(guang)(guang)亮、平整表面(mian)的(de)(de)加(jia)工(gong)方(fang)法。拋(pao)光(guang)(guang)是(shi)(shi)安排在工(gong)件精加(jia)工(gong)之后(hou)進行，拋(pao)光(guang)(guang)之后(hou)的(de)(de)工(gong)件，粗糙度R值可達0.1-0.012μm，并能(neng)明顯增加(jia)光(guang)(guang)亮度，但(dan)是(shi)(shi)不能(neng)保(bao)持原(yuan)有的(de)(de)精度。
硬質(zhi)合(he)金精密(mi)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)還(huan)有(you)很多加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)方式，如CNC銑削加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)、慢走絲(si)線切割(ge)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)、電火花加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)、數控車床加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)等等，今天給大家介紹的(de)還(huan)只是磨加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)一小(xiao)部(bu)分，硬質(zhi)合(he)金精密(mi)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)是一門大學問，公司在(zai)硬質(zhi)合(he)金精密(mi)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)方面擁有(you)非(fei)常雄厚的(de)實力，配備(bei)(bei)各類(lei)先進加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)設備(bei)(bei)，適用于各類(lei)高(gao)精密(mi)、特(te)種材料、偏心內外(wai)形、彎頭、復雜幾何零件的(de)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，歡(huan)迎前(qian)來咨詢。
