關于硬質(zhi)合金精(jing)密加(jia)工(gong)的介紹
硬質(zhi)合(he)(he)金是(shi)一種硬度非常(chang)高(gao)的(de)(de)材料(liao)，其加(jia)工(gong)過程也是(shi)有一定難(nan)度的(de)(de)。近(jin)年來隨(sui)著科技的(de)(de)進步和生產的(de)(de)發展，很多工(gong)業領域對硬質(zhi)合(he)(he)金工(gong)件的(de)(de)加(jia)工(gong)要求(qiu)越來越高(gao)，包括精(jing)密公(gong)差尺寸和表面(mian)粗(cu)糙(cao)度的(de)(de)高(gao)要求(qiu)，以及一些(xie)堅硬難(nan)加(jia)工(gong)材料(liao)制成的(de)(de)復雜零件。對硬質(zhi)合(he)(he)金精(jing)密加(jia)工(gong)提出了新的(de)(de)挑戰(zhan)。今天，西迪小編給大(da)家分享的(de)(de)便是(shi)關(guan)于硬質(zhi)合(he)(he)金精(jing)密加(jia)工(gong)的(de)(de)相關(guan)知識。
硬質合(he)金精(jing)(jing)(jing)密加(jia)(jia)(jia)工(gong)(gong)(gong)包(bao)括精(jing)(jing)(jing)整加(jia)(jia)(jia)工(gong)(gong)(gong)和光整加(jia)(jia)(jia)工(gong)(gong)(gong)，精(jing)(jing)(jing)整加(jia)(jia)(jia)工(gong)(gong)(gong)是生(sheng)產中常用的(de)精(jing)(jing)(jing)密加(jia)(jia)(jia)工(gong)(gong)(gong)，指(zhi)的(de)是在精(jing)(jing)(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)之后(hou)從工(gong)(gong)(gong)件上(shang)切除很薄的(de)材料層，以提高工(gong)(gong)(gong)件的(de)精(jing)(jing)(jing)度(du)(du)和減少表面的(de)粗糙(cao)度(du)(du)值為目的(de)的(de)加(jia)(jia)(jia)工(gong)(gong)(gong)方法，如(ru)研(yan)磨(mo)(mo)、珩(heng)磨(mo)(mo)等。而(er)精(jing)(jing)(jing)密加(jia)(jia)(jia)工(gong)(gong)(gong)的(de)光整加(jia)(jia)(jia)工(gong)(gong)(gong)是指(zhi)不切除或者從工(gong)(gong)(gong)件上(shang)切除極薄材料層，以降低表面粗糙(cao)度(du)(du)為目的(de)的(de)加(jia)(jia)(jia)工(gong)(gong)(gong)方法，比(bi)如(ru)超精(jing)(jing)(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)、拋光等。
硬質合(he)金精密加工(gong)的研磨是用(yong)研磨工(gong)具和研磨劑，從工(gong)件上研去一層極(ji)薄(bo)表面層的精加工(gong)方法(fa)。
采用不同的研(yan)(yan)磨(mo)(mo)工(gong)具(ju)，比如研(yan)(yan)磨(mo)(mo)芯(xin)棒(bang)、研(yan)(yan)磨(mo)(mo)套、研(yan)(yan)磨(mo)(mo)平板等(deng)，可對硬質合(he)金(jin)的內圓、外圓和平面(mian)等(deng)進行(xing)研(yan)(yan)磨(mo)(mo)。為(wei)了(le)磨(mo)(mo)料能嵌入研(yan)(yan)磨(mo)(mo)套的內表面(mian)，研(yan)(yan)磨(mo)(mo)套的材料應該軟一(yi)些，常用的是鑄鐵。研(yan)(yan)磨(mo)(mo)時先在工(gong)具(ju)表面(mian)涂上(shang)一(yi)層均勻(yun)的研(yan)(yan)磨(mo)(mo)劑，手持(chi)研(yan)(yan)磨(mo)(mo)工(gong)具(ju)在軸上(shang)來回移動，直至達(da)到研(yan)(yan)磨(mo)(mo)要求為(wei)止。
研磨的精密加工(gong)方法(fa)具有以下特點：
1、 經過(guo)研磨后(hou)的(de)工件表(biao)面(mian)，尺寸精度(du)可(ke)以(yi)達到IT4-IT1級；表(biao)面(mian)粗糙度(du)值可(ke)減小到0.1-0.0006μm。形狀(zhuang)精度(du)可(ke)相應提高(gao)。
2、 生(sheng)產效率比較(jiao)低(di)，加工余量小。
3、 研磨劑(ji)易飛濺，污染環(huan)境(jing)。
在現代制造(zao)業中，研磨(mo)應用非常廣，許多精密量(liang)塊、量(liang)規、齒(chi)輪、鋼(gang)球、噴油嘴(zui)、石英晶體、陶瓷(ci)元件(jian)等零件(jian)均需研磨(mo)。
我(wo)們再來看看硬質合金精(jing)密加工(gong)(gong)的另外(wai)一種(zhong)加工(gong)(gong)方(fang)(fang)式珩(heng)磨(mo)。珩(heng)磨(mo)的加工(gong)(gong)原理是(shi)利(li)用珩(heng)磨(mo)工(gong)(gong)具(ju)(ju)對(dui)工(gong)(gong)件表面施加一定壓力，珩(heng)磨(mo)工(gong)(gong)具(ju)(ju)同時作往(wang)復振動、相對(dui)旋轉和直線往(wang)復運動，切除工(gong)(gong)件上極小的余量(liang)的精(jing)密加工(gong)(gong)方(fang)(fang)法(fa)。
拋光(guang)是利用機(ji)械、化學(xue)(xue)或(huo)電(dian)化學(xue)(xue)地作用，使工(gong)件(jian)(jian)獲的(de)光(guang)亮、平整表面的(de)加(jia)工(gong)方法。拋光(guang)是安排(pai)在工(gong)件(jian)(jian)精加(jia)工(gong)之后進(jin)行，拋光(guang)之后的(de)工(gong)件(jian)(jian)，粗(cu)糙度R值可達0.1-0.012μm，并能明(ming)顯增加(jia)光(guang)亮度，但是不能保持原有(you)的(de)精度。
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，如CNC銑削加(jia)工(gong)(gong)(gong)(gong)(gong)、慢走絲(si)線(xian)切割加(jia)工(gong)(gong)(gong)(gong)(gong)、電火(huo)花加(jia)工(gong)(gong)(gong)(gong)(gong)、數控車床加(jia)工(gong)(gong)(gong)(gong)(gong)等(deng)(deng)等(deng)(deng)，今天給(gei)大(da)家介紹(shao)的(de)還只(zhi)是(shi)磨加(jia)工(gong)(gong)(gong)(gong)(gong)的(de)一(yi)小部分，硬(ying)質合(he)金精密加(jia)工(gong)(gong)(gong)(gong)(gong)是(shi)一(yi)門大(da)學(xue)問，公司在硬(ying)質合(he)金精密加(jia)工(gong)(gong)(gong)(gong)(gong)方面擁有非(fei)常雄厚的(de)實力，配備各類先進加(jia)工(gong)(gong)(gong)(gong)(gong)設備，適用(yong)于各類高精密、特種材(cai)料、偏心內外形(xing)、彎頭、復雜幾何(he)零件的(de)加(jia)工(gong)(gong)(gong)(gong)(gong)，歡迎前來咨詢(xun)。
