精密機械零件加工是一種用加工機械對工件的外形尺寸或性能進行改變的過程。一般精密機械加工的定義是指按步驟,按工(gong)(gong)(gong)序完成各主要(yao)表面(mian)的加工(gong)(gong)(gong),其(qi)中包括(kuo)有工(gong)(gong)(gong)件(jian)平行度(du),表面(mian)光潔度(du),表面(mian)垂直度(du),表面(mian)硬度(du)等等,可以讓零件(jian)的加工(gong)(gong)(gong)精度(du)以及加工(gong)(gong)(gong)表面(mian)質量(liang)達到圖(tu)紙規(gui)定的要(yao)求。
平行(xing)度(du)要(yao)求(qiu)(qiu):就是要(yao)求(qiu)(qiu)工件周圍的(de)公(gong)差要(yao)求(qiu)(qiu),比如(ru)是矩形的(de)工件,那就需要(yao)工件四個角(jiao)的(de)厚(hou)度(du)要(yao)達到(dao)一定(ding)的(de)公(gong)差范圍內,如(ru)果四邊(bian)的(de)厚(hou)度(du)達不(bu)到(dao)公(gong)差的(de)要(yao)求(qiu)(qiu),則達不(bu)到(dao)平行(xing)度(du)的(de)要(yao)求(qiu)(qiu)。
垂直度要求(qiu):就(jiu)是(shi)要求(qiu)工件的側面和地面達(da)到公差要求(qiu),可以理解成正(zheng)當體,從數軸來看,分為XYZ三面,一(yi)般要求(qiu)XZ,YZ達(da)到公差要求(qiu),出現誤差也和平行度要求(qiu)的大致,一(yi)般按照平行度要求(qiu)來處理則(ze)可。
同(tong)時(shi)我們精密機(ji)械零(ling)件加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)按照它所處的的溫(wen)度狀(zhuang)(zhuang)態﹐分為冷(leng)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)和(he)熱(re)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)。一(yi)般(ban)在常溫(wen)下加(jia)(jia)工(gong)(gong)(gong)(gong)(gong),并且不引起(qi)工(gong)(gong)(gong)(gong)(gong)件的化學或物相變化﹐稱冷(leng)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)。一(yi)般(ban)在高于或低于常溫(wen)狀(zhuang)(zhuang)態的加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)﹐會引起(qi)工(gong)(gong)(gong)(gong)(gong)件的化學或物相變化﹐稱熱(re)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)。冷(leng)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)按加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)方式的差(cha)別可分為切削(xue)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)和(he)壓力加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)。熱(re)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)常見有熱(re)處理﹐鍛(duan)造(zao)﹐鑄(zhu)造(zao)和(he)焊(han)接。
