關于硬質(zhi)合(he)金精密加(jia)工的介(jie)紹
硬質(zhi)合金(jin)是一(yi)種(zhong)硬度(du)非常高(gao)的(de)材料(liao)，其加工(gong)(gong)過程也是有一(yi)定難度(du)的(de)。近年來隨著科技的(de)進步和生產的(de)發展(zhan)，很多(duo)工(gong)(gong)業領域對硬質(zhi)合金(jin)工(gong)(gong)件的(de)加工(gong)(gong)要(yao)求越來越高(gao)，包括精(jing)(jing)密(mi)公差尺(chi)寸和表(biao)面粗糙(cao)度(du)的(de)高(gao)要(yao)求，以及(ji)一(yi)些(xie)堅硬難加工(gong)(gong)材料(liao)制(zhi)成的(de)復(fu)雜零件。對硬質(zhi)合金(jin)精(jing)(jing)密(mi)加工(gong)(gong)提(ti)出了新的(de)挑戰。今天，西迪小(xiao)編(bian)給大家分(fen)享的(de)便是關于硬質(zhi)合金(jin)精(jing)(jing)密(mi)加工(gong)(gong)的(de)相關知識。
硬質合(he)金精(jing)(jing)(jing)密(mi)(mi)加(jia)(jia)工(gong)(gong)(gong)(gong)包括精(jing)(jing)(jing)整加(jia)(jia)工(gong)(gong)(gong)(gong)和光整加(jia)(jia)工(gong)(gong)(gong)(gong)，精(jing)(jing)(jing)整加(jia)(jia)工(gong)(gong)(gong)(gong)是生產中常用的(de)(de)精(jing)(jing)(jing)密(mi)(mi)加(jia)(jia)工(gong)(gong)(gong)(gong)，指(zhi)的(de)(de)是在精(jing)(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)之后從工(gong)(gong)(gong)(gong)件上(shang)切(qie)除(chu)很薄的(de)(de)材料(liao)(liao)層(ceng)，以提高工(gong)(gong)(gong)(gong)件的(de)(de)精(jing)(jing)(jing)度和減少表面的(de)(de)粗(cu)糙度值為(wei)目的(de)(de)的(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)方(fang)法，如(ru)研磨、珩磨等(deng)。而(er)精(jing)(jing)(jing)密(mi)(mi)加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)(de)光整加(jia)(jia)工(gong)(gong)(gong)(gong)是指(zhi)不切(qie)除(chu)或者從工(gong)(gong)(gong)(gong)件上(shang)切(qie)除(chu)極薄材料(liao)(liao)層(ceng)，以降低表面粗(cu)糙度為(wei)目的(de)(de)的(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)方(fang)法，比如(ru)超精(jing)(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)、拋光等(deng)。
硬質合金(jin)精密加(jia)(jia)工的研磨是用研磨工具和研磨劑，從(cong)工件上研去一層極(ji)薄(bo)表面層的精加(jia)(jia)工方法。
采用(yong)不同的研(yan)磨(mo)(mo)(mo)工具(ju)，比如研(yan)磨(mo)(mo)(mo)芯棒、研(yan)磨(mo)(mo)(mo)套、研(yan)磨(mo)(mo)(mo)平(ping)板等(deng)(deng)，可對(dui)硬(ying)質(zhi)合(he)金的內圓、外圓和(he)平(ping)面等(deng)(deng)進行研(yan)磨(mo)(mo)(mo)。為(wei)了磨(mo)(mo)(mo)料(liao)(liao)能嵌入研(yan)磨(mo)(mo)(mo)套的內表面，研(yan)磨(mo)(mo)(mo)套的材料(liao)(liao)應該軟一些，常用(yong)的是鑄鐵。研(yan)磨(mo)(mo)(mo)時先(xian)在(zai)工具(ju)表面涂上(shang)一層均勻的研(yan)磨(mo)(mo)(mo)劑(ji)，手持研(yan)磨(mo)(mo)(mo)工具(ju)在(zai)軸上(shang)來回移動，直(zhi)至(zhi)達到研(yan)磨(mo)(mo)(mo)要(yao)求為(wei)止。
研(yan)磨的精(jing)密加工方法具(ju)有以下特點(dian)：
1、 經過研磨后的工件表面，尺寸精度可以達到IT4-IT1級；表面粗糙度值可減小到0.1-0.0006μm。形狀(zhuang)精度可相應(ying)提高(gao)。
2、 生產效率比(bi)較低(di)，加工余量小。
3、 研(yan)磨(mo)劑易(yi)飛濺，污染環境。
在(zai)現代制(zhi)造業中，研磨(mo)(mo)應用(yong)非常廣，許多精密量塊(kuai)、量規、齒輪、鋼球(qiu)、噴油嘴、石英晶體(ti)、陶瓷元件等(deng)零件均需研磨(mo)(mo)。
我們再來看看硬質合(he)金精(jing)密加(jia)工(gong)(gong)(gong)的(de)另外一(yi)(yi)種加(jia)工(gong)(gong)(gong)方(fang)式珩(heng)磨(mo)。珩(heng)磨(mo)的(de)加(jia)工(gong)(gong)(gong)原理是利(li)用珩(heng)磨(mo)工(gong)(gong)(gong)具對工(gong)(gong)(gong)件表面施加(jia)一(yi)(yi)定壓力，珩(heng)磨(mo)工(gong)(gong)(gong)具同(tong)時作往復(fu)振(zhen)動、相(xiang)對旋轉和直線往復(fu)運動，切除工(gong)(gong)(gong)件上極(ji)小的(de)余量(liang)的(de)精(jing)密加(jia)工(gong)(gong)(gong)方(fang)法(fa)。
拋光(guang)是(shi)利用(yong)機械(xie)、化學或電化學地作用(yong)，使工(gong)(gong)件(jian)獲的光(guang)亮、平整表面的加工(gong)(gong)方法(fa)。拋光(guang)是(shi)安排(pai)在工(gong)(gong)件(jian)精(jing)加工(gong)(gong)之后(hou)進行(xing)，拋光(guang)之后(hou)的工(gong)(gong)件(jian)，粗(cu)糙(cao)度R值(zhi)可達0.1-0.012μm，并能(neng)明顯增加光(guang)亮度，但是(shi)不能(neng)保持原有的精(jing)度。
硬質(zhi)合金(jin)(jin)精(jing)密加(jia)工(gong)(gong)(gong)還有很多加(jia)工(gong)(gong)(gong)方式，如CNC銑削加(jia)工(gong)(gong)(gong)、慢走絲(si)線切割加(jia)工(gong)(gong)(gong)、電火花加(jia)工(gong)(gong)(gong)、數控(kong)車床加(jia)工(gong)(gong)(gong)等等，今天給大(da)家介紹的還只是(shi)磨加(jia)工(gong)(gong)(gong)的一小部分(fen)，硬質(zhi)合金(jin)(jin)精(jing)密加(jia)工(gong)(gong)(gong)是(shi)一門大(da)學(xue)問，公司在硬質(zhi)合金(jin)(jin)精(jing)密加(jia)工(gong)(gong)(gong)方面擁有非常雄厚的實力，配備各類先(xian)進加(jia)工(gong)(gong)(gong)設備，適用于各類高精(jing)密、特種材料、偏心內外形、彎頭、復雜幾何零(ling)件的加(jia)工(gong)(gong)(gong)，歡迎前來(lai)咨詢(xun)。
