        如何提高模具配件加工質量及穩定性、可靠性，下面由合肥模具廠超威模(mo)具(ju)有限公司衛經理闡述如(ru)下幾(ji)點：

　　對復(fu)(fu)(fu)雜型腔和(he)(he)多(duo)功(gong)能(neng)復(fu)(fu)(fu)合(he)模(mo)具(ju)，隨著制(zhi)件形(xing)狀的(de)復(fu)(fu)(fu)雜化，必須要提高模(mo)具(ju)的(de)設計制(zhi)造水平，多(duo)種 溝槽(cao)、多(duo)種材(cai)質(zhi)在(zai)一套(tao)模(mo)具(ju)中成(cheng)形(xing)或組裝(zhuang)成(cheng)組件的(de)多(duo)功(gong)能(neng)復(fu)(fu)(fu)合(he)模(mo)具(ju)，就要求加工(gong)編(bian)程程序量大，具(ju)有(you)高深 孔(kong)腔綜(zong)合(he)切削能(neng)力(li)和(he)(he)高穩(wen)定性，提高了加工(gong)難度。  

　　模(mo)具(ju)配件加(jia)工(gong)質量(liang)包(bao)括加(jia)工(gong)精度(du)及(ji)表面質量(liang)：加(jia)工(gong)精度(du)是加(jia)工(gong)后零件表面的(de)實(shi)際(ji)尺寸、形狀、位置三種幾何(he)參數(shu)與圖(tu)紙要求的(de)理(li)想幾何(he)參數(shu)的(de)符(fu)合程(cheng)度(du)；零件實(shi)際(ji)幾何(he)參數(shu)與理(li)想幾何(he)參數(shu)的(de)偏離數(shu)值稱(cheng)為加(jia)工(gong)誤差。

　　加(jia)(jia)工(gong)(gong)(gong)(gong)精度(du)與加(jia)(jia)工(gong)(gong)(gong)(gong)誤(wu)(wu)差都是評價加(jia)(jia)工(gong)(gong)(gong)(gong)表面幾(ji)何參數的(de)(de)(de)術語。加(jia)(jia)工(gong)(gong)(gong)(gong)精度(du)用公差等(deng)級衡量，等(deng)級值(zhi)越(yue)小，其精度(du)越(yue)高；加(jia)(jia)工(gong)(gong)(gong)(gong)誤(wu)(wu)差用數值(zhi)表示，數值(zhi)越(yue)大，其誤(wu)(wu)差越(yue)大。加(jia)(jia)工(gong)(gong)(gong)(gong)精度(du)高，就是加(jia)(jia)工(gong)(gong)(gong)(gong)誤(wu)(wu)差小，反之亦然(ran)；任(ren)何加(jia)(jia)工(gong)(gong)(gong)(gong)方法所得到的(de)(de)(de)實際參數都不會絕(jue)對準確，從(cong)零件的(de)(de)(de)功能看，只(zhi)要加(jia)(jia)工(gong)(gong)(gong)(gong)誤(wu)(wu)差在零件圖(tu)要求的(de)(de)(de)公差范(fan)圍內，就認為保證(zheng)了(le)加(jia)(jia)工(gong)(gong)(gong)(gong)精度(du)。

　　機器的(de)(de)(de)質量取(qu)決于零(ling)(ling)件(jian)(jian)(jian)的(de)(de)(de)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)質量和機器的(de)(de)(de)裝配(pei)質量，零(ling)(ling)件(jian)(jian)(jian)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)質量包含(han)零(ling)(ling)件(jian)(jian)(jian)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精度(du)(du)和表(biao)面質量兩大部(bu)分(fen)機械加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精度(du)(du)是指零(ling)(ling)件(jian)(jian)(jian)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)后(hou)的(de)(de)(de)實際幾何(he)參數（尺(chi)(chi)寸(cun)(cun)(cun)、形(xing)狀和位置(zhi)）與理想幾何(he)參數相(xiang)符(fu)合(he)的(de)(de)(de)程(cheng)度(du)(du)。它(ta)們之間的(de)(de)(de)差(cha)異稱為加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)誤(wu)差(cha)。加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)誤(wu)差(cha)的(de)(de)(de)大小反(fan)映了加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精度(du)(du)的(de)(de)(de)高低。誤(wu)差(cha)越(yue)大加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精度(du)(du)越(yue)低，誤(wu)差(cha)越(yue)小加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精度(du)(du)越(yue)高；影響加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精度(du)(du)的(de)(de)(de)主要(yao)方面：尺(chi)(chi)寸(cun)(cun)(cun)精度(du)(du)，加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)后(hou)零(ling)(ling)件(jian)(jian)(jian)的(de)(de)(de)實際尺(chi)(chi)寸(cun)(cun)(cun)與零(ling)(ling)件(jian)(jian)(jian)尺(chi)(chi)寸(cun)(cun)(cun)的(de)(de)(de)公差(cha)帶中心的(de)(de)(de)相(xiang)符(fu)合(he)程(cheng)度(du)(du)。

         綜上所述觀點(dian)：如何提高模具制(zhi)造穩定及(ji)可靠性，以上闡述幾點(dian)希望對制(zhi)作工(gong)人們有(you)所幫(bang)忙(mang)，感謝信任及(ji)了解模具知識。
