關于(yu)硬質合金精(jing)密加工的介紹
硬(ying)(ying)(ying)(ying)質合(he)(he)金(jin)是一(yi)(yi)種(zhong)硬(ying)(ying)(ying)(ying)度非常高的(de)材料(liao)，其加工(gong)過(guo)程也是有(you)一(yi)(yi)定難(nan)度的(de)。近年(nian)來隨著科技的(de)進步和生產的(de)發展(zhan)，很多(duo)工(gong)業(ye)領域(yu)對(dui)(dui)硬(ying)(ying)(ying)(ying)質合(he)(he)金(jin)工(gong)件的(de)加工(gong)要求越(yue)來越(yue)高，包(bao)括精(jing)密公差尺寸和表面粗糙度的(de)高要求，以及一(yi)(yi)些堅硬(ying)(ying)(ying)(ying)難(nan)加工(gong)材料(liao)制成的(de)復(fu)雜零件。對(dui)(dui)硬(ying)(ying)(ying)(ying)質合(he)(he)金(jin)精(jing)密加工(gong)提出了新的(de)挑戰。今(jin)天，西(xi)迪小編給大(da)家分(fen)享的(de)便(bian)是關于(yu)硬(ying)(ying)(ying)(ying)質合(he)(he)金(jin)精(jing)密加工(gong)的(de)相關知識。
硬質(zhi)合(he)金精(jing)(jing)(jing)(jing)密(mi)加(jia)(jia)工(gong)(gong)(gong)包括(kuo)精(jing)(jing)(jing)(jing)整加(jia)(jia)工(gong)(gong)(gong)和(he)光整加(jia)(jia)工(gong)(gong)(gong)，精(jing)(jing)(jing)(jing)整加(jia)(jia)工(gong)(gong)(gong)是生產中常用的(de)精(jing)(jing)(jing)(jing)密(mi)加(jia)(jia)工(gong)(gong)(gong)，指(zhi)的(de)是在精(jing)(jing)(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)之后從工(gong)(gong)(gong)件(jian)上切(qie)除很薄的(de)材料層(ceng)，以提高工(gong)(gong)(gong)件(jian)的(de)精(jing)(jing)(jing)(jing)度(du)和(he)減(jian)少表面(mian)的(de)粗糙度(du)值(zhi)為目的(de)的(de)加(jia)(jia)工(gong)(gong)(gong)方法，如(ru)研(yan)磨(mo)、珩磨(mo)等。而精(jing)(jing)(jing)(jing)密(mi)加(jia)(jia)工(gong)(gong)(gong)的(de)光整加(jia)(jia)工(gong)(gong)(gong)是指(zhi)不切(qie)除或者(zhe)從工(gong)(gong)(gong)件(jian)上切(qie)除極薄材料層(ceng)，以降(jiang)低表面(mian)粗糙度(du)為目的(de)的(de)加(jia)(jia)工(gong)(gong)(gong)方法，比如(ru)超精(jing)(jing)(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)、拋(pao)光等。
硬(ying)質合(he)金精(jing)密加工(gong)的(de)研(yan)磨是用(yong)研(yan)磨工(gong)具和(he)研(yan)磨劑，從(cong)工(gong)件上研(yan)去一層極薄(bo)表面層的(de)精(jing)加工(gong)方法。
采用(yong)(yong)不同的研(yan)(yan)(yan)(yan)(yan)磨(mo)工具，比如研(yan)(yan)(yan)(yan)(yan)磨(mo)芯棒(bang)、研(yan)(yan)(yan)(yan)(yan)磨(mo)套、研(yan)(yan)(yan)(yan)(yan)磨(mo)平板等，可對硬質合金(jin)的內圓、外圓和平面(mian)等進行研(yan)(yan)(yan)(yan)(yan)磨(mo)。為了磨(mo)料(liao)能嵌入研(yan)(yan)(yan)(yan)(yan)磨(mo)套的內表(biao)(biao)面(mian)，研(yan)(yan)(yan)(yan)(yan)磨(mo)套的材料(liao)應該軟一些，常用(yong)(yong)的是(shi)鑄鐵。研(yan)(yan)(yan)(yan)(yan)磨(mo)時(shi)先在(zai)工具表(biao)(biao)面(mian)涂上一層均(jun)勻的研(yan)(yan)(yan)(yan)(yan)磨(mo)劑，手持(chi)研(yan)(yan)(yan)(yan)(yan)磨(mo)工具在(zai)軸上來回移(yi)動(dong)，直至達到研(yan)(yan)(yan)(yan)(yan)磨(mo)要求(qiu)為止。
研磨的(de)精密(mi)加工方法具有以(yi)下特點：
1、 經過研(yan)磨(mo)后的工件表面，尺寸精(jing)度(du)可(ke)以達到IT4-IT1級；表面粗糙度(du)值(zhi)可(ke)減(jian)小到0.1-0.0006μm。形狀精(jing)度(du)可(ke)相應提高(gao)。
2、 生產效(xiao)率比(bi)較低，加工余量小(xiao)。
3、 研(yan)磨劑易飛濺，污染(ran)環(huan)境。
在現代制造(zao)業中，研磨應用(yong)非常廣，許多精密量塊、量規、齒(chi)輪、鋼球(qiu)、噴油嘴、石英(ying)晶體、陶瓷元件等零件均需研磨。
我們再來看(kan)看(kan)硬質(zhi)合金精密加(jia)(jia)工(gong)(gong)(gong)的另外一種(zhong)加(jia)(jia)工(gong)(gong)(gong)方式珩(heng)磨(mo)(mo)。珩(heng)磨(mo)(mo)的加(jia)(jia)工(gong)(gong)(gong)原理(li)是利(li)用珩(heng)磨(mo)(mo)工(gong)(gong)(gong)具對工(gong)(gong)(gong)件表(biao)面施加(jia)(jia)一定壓(ya)力，珩(heng)磨(mo)(mo)工(gong)(gong)(gong)具同(tong)時作(zuo)往復振動(dong)、相(xiang)對旋轉和直線往復運(yun)動(dong)，切除工(gong)(gong)(gong)件上極小的余量的精密加(jia)(jia)工(gong)(gong)(gong)方法(fa)。
拋光是(shi)利用機械、化學或電化學地(di)作(zuo)用，使(shi)工(gong)件(jian)獲(huo)的(de)(de)光亮(liang)、平整表面的(de)(de)加工(gong)方法。拋光是(shi)安排在工(gong)件(jian)精加工(gong)之(zhi)后進行，拋光之(zhi)后的(de)(de)工(gong)件(jian)，粗糙度(du)R值(zhi)可(ke)達0.1-0.012μm，并能明顯增(zeng)加光亮(liang)度(du)，但是(shi)不能保持原有的(de)(de)精度(du)。
硬(ying)質合金(jin)精(jing)密加(jia)工(gong)(gong)還有很(hen)多加(jia)工(gong)(gong)方(fang)式，如CNC銑(xian)削加(jia)工(gong)(gong)、慢(man)走絲線切(qie)割加(jia)工(gong)(gong)、電(dian)火花加(jia)工(gong)(gong)、數(shu)控(kong)車(che)床加(jia)工(gong)(gong)等等，今(jin)天給(gei)大家介紹的(de)還只是(shi)磨加(jia)工(gong)(gong)的(de)一小部分，硬(ying)質合金(jin)精(jing)密加(jia)工(gong)(gong)是(shi)一門大學(xue)問，公司在硬(ying)質合金(jin)精(jing)密加(jia)工(gong)(gong)方(fang)面擁有非(fei)常雄厚的(de)實力，配備各類先進加(jia)工(gong)(gong)設備，適(shi)用(yong)于各類高精(jing)密、特(te)種(zhong)材料、偏心(xin)內外形(xing)、彎頭、復雜(za)幾(ji)何(he)零件的(de)加(jia)工(gong)(gong)，歡迎前來(lai)咨詢。
