關于(yu)硬(ying)質合金(jin)精密加工的介(jie)紹
硬(ying)(ying)質合金(jin)是一(yi)(yi)種硬(ying)(ying)度非常(chang)高的(de)材料，其(qi)加(jia)工(gong)(gong)過程也是有(you)一(yi)(yi)定難(nan)度的(de)。近(jin)年來隨著(zhu)科技的(de)進步和(he)生產(chan)的(de)發展，很多工(gong)(gong)業領(ling)域對硬(ying)(ying)質合金(jin)工(gong)(gong)件(jian)的(de)加(jia)工(gong)(gong)要求越來越高，包(bao)括精密(mi)(mi)公差尺寸(cun)和(he)表面(mian)粗糙(cao)度的(de)高要求，以及一(yi)(yi)些堅(jian)硬(ying)(ying)難(nan)加(jia)工(gong)(gong)材料制成的(de)復雜零件(jian)。對硬(ying)(ying)質合金(jin)精密(mi)(mi)加(jia)工(gong)(gong)提出(chu)了新的(de)挑戰(zhan)。今天，西迪小編(bian)給大(da)家分享的(de)便是關于硬(ying)(ying)質合金(jin)精密(mi)(mi)加(jia)工(gong)(gong)的(de)相關知識。
硬(ying)質合金精(jing)(jing)密加(jia)(jia)工(gong)(gong)(gong)包括精(jing)(jing)整加(jia)(jia)工(gong)(gong)(gong)和光(guang)整加(jia)(jia)工(gong)(gong)(gong)，精(jing)(jing)整加(jia)(jia)工(gong)(gong)(gong)是生產中常用的(de)(de)(de)精(jing)(jing)密加(jia)(jia)工(gong)(gong)(gong)，指的(de)(de)(de)是在精(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)之后從(cong)工(gong)(gong)(gong)件(jian)(jian)上切除(chu)很薄(bo)的(de)(de)(de)材(cai)料層(ceng)，以提高工(gong)(gong)(gong)件(jian)(jian)的(de)(de)(de)精(jing)(jing)度和減少表面(mian)的(de)(de)(de)粗糙(cao)度值為目的(de)(de)(de)的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)方法，如研磨(mo)、珩(heng)磨(mo)等。而(er)精(jing)(jing)密加(jia)(jia)工(gong)(gong)(gong)的(de)(de)(de)光(guang)整加(jia)(jia)工(gong)(gong)(gong)是指不切除(chu)或者從(cong)工(gong)(gong)(gong)件(jian)(jian)上切除(chu)極薄(bo)材(cai)料層(ceng)，以降(jiang)低(di)表面(mian)粗糙(cao)度為目的(de)(de)(de)的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)方法，比如超(chao)精(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)、拋光(guang)等。
硬質合金精密加工的研(yan)磨(mo)是(shi)用研(yan)磨(mo)工具(ju)和(he)研(yan)磨(mo)劑，從工件(jian)上(shang)研(yan)去一層極薄表面層的精加工方法(fa)。
采用不同的研(yan)(yan)(yan)磨(mo)工具(ju)(ju)，比(bi)如研(yan)(yan)(yan)磨(mo)芯棒、研(yan)(yan)(yan)磨(mo)套(tao)(tao)、研(yan)(yan)(yan)磨(mo)平板等，可對(dui)硬質合金的內(nei)圓、外(wai)圓和平面等進行(xing)研(yan)(yan)(yan)磨(mo)。為了磨(mo)料能嵌入研(yan)(yan)(yan)磨(mo)套(tao)(tao)的內(nei)表面，研(yan)(yan)(yan)磨(mo)套(tao)(tao)的材料應(ying)該軟一(yi)些(xie)，常用的是(shi)鑄鐵(tie)。研(yan)(yan)(yan)磨(mo)時先在(zai)工具(ju)(ju)表面涂上一(yi)層(ceng)均勻的研(yan)(yan)(yan)磨(mo)劑，手持研(yan)(yan)(yan)磨(mo)工具(ju)(ju)在(zai)軸上來回移動(dong)，直至(zhi)達到研(yan)(yan)(yan)磨(mo)要求(qiu)為止。
研磨(mo)的精密加(jia)工方法(fa)具有以下特點：
1、 經過研磨(mo)后的工件表(biao)面，尺(chi)寸精(jing)度(du)可以達到(dao)IT4-IT1級；表(biao)面粗(cu)糙(cao)度(du)值(zhi)可減小到(dao)0.1-0.0006μm。形狀(zhuang)精(jing)度(du)可相應提高(gao)。
2、 生產效率比較低，加(jia)工余(yu)量小。
3、 研磨劑(ji)易(yi)飛(fei)濺，污染環境。
在(zai)現代(dai)制造業中，研磨應(ying)用非常(chang)廣，許多精密量塊、量規、齒輪、鋼球、噴油(you)嘴(zui)、石英晶體、陶瓷元件等(deng)零件均需研磨。
我們再來看看硬質合金精密(mi)加工(gong)(gong)的另外一(yi)種加工(gong)(gong)方式(shi)珩磨。珩磨的加工(gong)(gong)原理是利用珩磨工(gong)(gong)具對工(gong)(gong)件表面施加一(yi)定壓力，珩磨工(gong)(gong)具同時作往復(fu)振動、相對旋轉和(he)直線(xian)往復(fu)運(yun)動，切除工(gong)(gong)件上極小(xiao)的余量的精密(mi)加工(gong)(gong)方法。
拋(pao)光(guang)(guang)(guang)是(shi)利(li)用(yong)機械、化學(xue)(xue)或電化學(xue)(xue)地(di)作用(yong)，使工(gong)件獲(huo)的(de)光(guang)(guang)(guang)亮、平整表面的(de)加工(gong)方法(fa)。拋(pao)光(guang)(guang)(guang)是(shi)安排在工(gong)件精加工(gong)之后進行，拋(pao)光(guang)(guang)(guang)之后的(de)工(gong)件，粗糙度R值(zhi)可達0.1-0.012μm，并能(neng)明顯增加光(guang)(guang)(guang)亮度，但是(shi)不能(neng)保持(chi)原有(you)的(de)精度。
硬(ying)質合金(jin)(jin)精(jing)密加(jia)工(gong)(gong)(gong)(gong)還有很多加(jia)工(gong)(gong)(gong)(gong)方(fang)式，如CNC銑削加(jia)工(gong)(gong)(gong)(gong)、慢走絲線切割(ge)加(jia)工(gong)(gong)(gong)(gong)、電(dian)火花加(jia)工(gong)(gong)(gong)(gong)、數控車床(chuang)加(jia)工(gong)(gong)(gong)(gong)等等，今天(tian)給大(da)家介(jie)紹的(de)還只是磨加(jia)工(gong)(gong)(gong)(gong)的(de)一小部(bu)分(fen)，硬(ying)質合金(jin)(jin)精(jing)密加(jia)工(gong)(gong)(gong)(gong)是一門大(da)學問，公(gong)司(si)在硬(ying)質合金(jin)(jin)精(jing)密加(jia)工(gong)(gong)(gong)(gong)方(fang)面擁有非常雄(xiong)厚的(de)實力，配備(bei)各(ge)(ge)類先進(jin)加(jia)工(gong)(gong)(gong)(gong)設備(bei)，適用于各(ge)(ge)類高精(jing)密、特(te)種材料、偏心內外形(xing)、彎頭、復雜幾何零件的(de)加(jia)工(gong)(gong)(gong)(gong)，歡迎前來咨詢(xun)。
