關于硬質合金精密加工(gong)的介(jie)紹
硬(ying)(ying)(ying)質(zhi)(zhi)合(he)金是一種硬(ying)(ying)(ying)度(du)(du)非常高(gao)的(de)(de)材料(liao)，其加(jia)(jia)工(gong)過程也是有一定(ding)難度(du)(du)的(de)(de)。近年來(lai)隨(sui)著科(ke)技的(de)(de)進(jin)步(bu)和生產的(de)(de)發展，很(hen)多(duo)工(gong)業(ye)領域對(dui)硬(ying)(ying)(ying)質(zhi)(zhi)合(he)金工(gong)件(jian)的(de)(de)加(jia)(jia)工(gong)要(yao)(yao)求越來(lai)越高(gao)，包(bao)括精密(mi)公差尺(chi)寸和表面(mian)粗糙(cao)度(du)(du)的(de)(de)高(gao)要(yao)(yao)求，以及(ji)一些堅硬(ying)(ying)(ying)難加(jia)(jia)工(gong)材料(liao)制成的(de)(de)復雜零件(jian)。對(dui)硬(ying)(ying)(ying)質(zhi)(zhi)合(he)金精密(mi)加(jia)(jia)工(gong)提出了(le)新的(de)(de)挑戰。今(jin)天，西迪小編給大家分享的(de)(de)便是關于硬(ying)(ying)(ying)質(zhi)(zhi)合(he)金精密(mi)加(jia)(jia)工(gong)的(de)(de)相(xiang)關知識。
硬質合金精(jing)(jing)密加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)包括精(jing)(jing)整(zheng)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)和光整(zheng)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)，精(jing)(jing)整(zheng)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)是(shi)生產中常用的(de)(de)(de)(de)精(jing)(jing)密加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)，指(zhi)的(de)(de)(de)(de)是(shi)在(zai)精(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)之后從工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)上切(qie)除很薄的(de)(de)(de)(de)材料(liao)層，以提高工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)的(de)(de)(de)(de)精(jing)(jing)度(du)和減少表面的(de)(de)(de)(de)粗糙度(du)值為目的(de)(de)(de)(de)的(de)(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)方法，如研磨、珩磨等(deng)(deng)。而(er)精(jing)(jing)密加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)(de)光整(zheng)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)是(shi)指(zhi)不切(qie)除或者從工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)上切(qie)除極薄材料(liao)層，以降(jiang)低表面粗糙度(du)為目的(de)(de)(de)(de)的(de)(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)方法，比如超精(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)、拋光等(deng)(deng)。
硬質合(he)金(jin)精密加工的(de)研(yan)磨(mo)(mo)是用研(yan)磨(mo)(mo)工具和(he)研(yan)磨(mo)(mo)劑，從(cong)工件上(shang)研(yan)去一層極薄表面層的(de)精加工方法。
采用不同的(de)研(yan)(yan)磨工(gong)具，比如(ru)研(yan)(yan)磨芯(xin)棒、研(yan)(yan)磨套、研(yan)(yan)磨平板等(deng)(deng)，可對(dui)硬質合(he)金的(de)內(nei)圓(yuan)、外圓(yuan)和平面(mian)等(deng)(deng)進行研(yan)(yan)磨。為(wei)(wei)了磨料能嵌入研(yan)(yan)磨套的(de)內(nei)表面(mian)，研(yan)(yan)磨套的(de)材料應(ying)該軟一(yi)些，常用的(de)是鑄鐵。研(yan)(yan)磨時先在(zai)工(gong)具表面(mian)涂(tu)上(shang)(shang)一(yi)層均勻的(de)研(yan)(yan)磨劑，手持研(yan)(yan)磨工(gong)具在(zai)軸上(shang)(shang)來回移動(dong)，直至達到研(yan)(yan)磨要(yao)求(qiu)為(wei)(wei)止。
研磨的(de)精密加工方法具(ju)有(you)以下特點：
1、 經過研(yan)磨后的(de)工件表(biao)面，尺(chi)寸精度可(ke)(ke)以達到IT4-IT1級；表(biao)面粗糙度值可(ke)(ke)減小到0.1-0.0006μm。形狀(zhuang)精度可(ke)(ke)相(xiang)應提高(gao)。
2、 生產效(xiao)率比(bi)較(jiao)低，加(jia)工余量小。
3、 研磨劑易飛濺，污染環(huan)境。
在現代制(zhi)造(zao)業中，研(yan)磨應(ying)用非常廣，許多精密(mi)量(liang)塊、量(liang)規、齒輪、鋼球、噴油嘴、石英晶(jing)體(ti)、陶瓷元件(jian)等(deng)零件(jian)均需研(yan)磨。
我們再來(lai)看看硬質合金精密加工(gong)(gong)的另外一種(zhong)加工(gong)(gong)方式珩磨(mo)。珩磨(mo)的加工(gong)(gong)原理是利(li)用珩磨(mo)工(gong)(gong)具對(dui)工(gong)(gong)件表面施加一定壓力，珩磨(mo)工(gong)(gong)具同時(shi)作往復(fu)(fu)振動(dong)、相對(dui)旋轉(zhuan)和直線往復(fu)(fu)運動(dong)，切除工(gong)(gong)件上(shang)極小的余量的精密加工(gong)(gong)方法。
拋(pao)光是利用機械(xie)、化學(xue)或電化學(xue)地(di)作(zuo)用，使工(gong)(gong)(gong)件獲的(de)光亮、平整表面的(de)加(jia)工(gong)(gong)(gong)方法。拋(pao)光是安排在工(gong)(gong)(gong)件精(jing)加(jia)工(gong)(gong)(gong)之(zhi)后(hou)進(jin)行，拋(pao)光之(zhi)后(hou)的(de)工(gong)(gong)(gong)件，粗(cu)糙度R值可達(da)0.1-0.012μm，并能明顯增加(jia)光亮度，但是不能保(bao)持(chi)原(yuan)有的(de)精(jing)度。
硬質合金精(jing)密(mi)加(jia)(jia)工(gong)還有(you)很(hen)多(duo)加(jia)(jia)工(gong)方式(shi)，如CNC銑削加(jia)(jia)工(gong)、慢走絲線切割加(jia)(jia)工(gong)、電(dian)火花加(jia)(jia)工(gong)、數控車床加(jia)(jia)工(gong)等(deng)等(deng)，今天(tian)給(gei)大家(jia)介(jie)紹(shao)的(de)(de)還只是磨(mo)加(jia)(jia)工(gong)的(de)(de)一小部分，硬質合金精(jing)密(mi)加(jia)(jia)工(gong)是一門大學問(wen)，公司(si)在(zai)硬質合金精(jing)密(mi)加(jia)(jia)工(gong)方面擁有(you)非(fei)常雄(xiong)厚的(de)(de)實力(li)，配備各(ge)類先進加(jia)(jia)工(gong)設備，適用(yong)于各(ge)類高精(jing)密(mi)、特種材料、偏心內(nei)外形、彎頭、復雜幾何零件(jian)的(de)(de)加(jia)(jia)工(gong)，歡迎前來咨(zi)詢。
