常用(yong)機(ji)(ji)械(xie)加(jia)工(gong)(gong)(gong)(gong)方式及特點：常用(yong)的機(ji)(ji)械(xie)金屬(shu)切削(xue)(xue)加(jia)工(gong)(gong)(gong)(gong)方法主(zhu)(zhu)要有車(che)(che)(che)削(xue)(xue)、銑削(xue)(xue)、鉆削(xue)(xue)、鏜削(xue)(xue)、刨削(xue)(xue)、拉削(xue)(xue)、磨(mo)削(xue)(xue)等。車(che)(che)(che)削(xue)(xue)：定義：工(gong)(gong)(gong)(gong)件(jian)(jian)旋轉作主(zhu)(zhu)運(yun)動(dong)(dong)，車(che)(che)(che)刀作進(jin)(jin)給運(yun)動(dong)(dong)的切削(xue)(xue)加(jia)工(gong)(gong)(gong)(gong)方法。車(che)(che)(che)削(xue)(xue)的主(zhu)(zhu)運(yun)動(dong)(dong)為(wei)零件(jian)(jian)旋轉運(yun)動(dong)(dong)，刀具直(zhi)線移動(dong)(dong)為(wei)進(jin)(jin)給運(yun)動(dong)(dong)，特別適用(yong)于加(jia)工(gong)(gong)(gong)(gong)回(hui)轉面。車(che)(che)(che)削(xue)(xue)的工(gong)(gong)(gong)(gong)藝特點：1.易于保證工(gong)(gong)(gong)(gong)件(jian)(jian)各(ge)加(jia)工(gong)(gong)(gong)(gong)面的位置(zhi)精度(du)（同軸(zhou)(zhou)度(du)要求、垂直(zhi)度(du)要求），2.生(sheng)產效(xiao)率(lv)高，3.生(sheng)產成本低，4.適用(yong)于加(jia)工(gong)(gong)(gong)(gong)的材料范圍(wei)(wei)廣。車(che)(che)(che)削(xue)(xue)的應(ying)(ying)用(yong)：單(dan)件(jian)(jian)小(xiao)批量生(sheng)產中，各(ge)種軸(zhou)(zhou)、盤(pan)、套類零件(jian)(jian)多(duo)選用(yong)適應(ying)(ying)性大(da)范圍(wei)(wei)的臥式車(che)(che)(che)床(chuang)或(huo)數控(kong)車(che)(che)(che)床(chuang)來(lai)加(jia)工(gong)(gong)(gong)(gong)。直(zhi)徑大(da)而長度(du)短的零件(jian)(jian)，多(duo)采用(yong)立式車(che)(che)(che)床(chuang)來(lai)加(jia)工(gong)(gong)(gong)(gong)。成批生(sheng)產外形(xing)較復雜(za)，具有內孔及螺紋的中小(xiao)型軸(zhou)(zhou)、套類零件(jian)(jian)時，應(ying)(ying)選用(yong)轉塔式車(che)(che)(che)床(chuang)進(jin)(jin)行加(jia)工(gong)(gong)(gong)(gong)。

機械加(jia)工(gong)(gong)零件(jian)表(biao)(biao)面質(zhi)量(liang)的控制注意(yi)事項：合理(li)的切削參數(shu)設(she)置是獲取表(biao)(biao)面質(zhi)量(liang)的關鍵因素。切削參數(shu)的含(han)義(yi)就(jiu)是指機械在(zai)加(jia)工(gong)(gong)過程中(zhong)利用(yong)的各種(zhong)各樣的加(jia)工(gong)(gong)數(shu)據，如(ru)刀具(ju)(ju)角(jiao)度(du)(du)(du)、切削速度(du)(du)(du)、切削深度(du)(du)(du)、進給速度(du)(du)(du)等。同時在(zai)加(jia)工(gong)(gong)零件(jian)的過程中(zhong)，我們應該根據零件(jian)的材(cai)質(zhi)以及尺(chi)寸(cun)形(xing)狀，來進行合理(li)的選(xuan)擇(ze)(ze)給予。就(jiu)是切削參數(shu)。在(zai)塑料加(jia)工(gong)(gong)過程中(zhong)，如(ru)果選(xuan)擇(ze)(ze)具(ju)(ju)有較大前角(jiao)的刀具(ju)(ju)，則可以實(shi)現抑制切屑(xie)堆積的效果。工(gong)(gong)具(ju)(ju)前角(jiao)的增加(jia)可以減小(xiao)工(gong)(gong)具(ju)(ju)的切削力和切削工(gong)(gong)具(ju)(ju)的變形(xing)。它縮(suo)短了切削工(gong)(gong)具(ju)(ju)和切削工(gong)(gong)具(ju)(ju)之(zhi)間(jian)的接觸長度(du)(du)(du)，并防止了切屑(xie)凸出的形(xing)成。常(chang)用(yong)機械加(jia)工(gong)(gong)方式有車削。

機(ji)械(xie)加(jia)(jia)(jia)工方法(fa)和適用(yong)(yong)范圍(wei)應該怎么選擇(ze)呢？刨(bao)(bao)(bao)(bao)削(xue)(xue)加(jia)(jia)(jia)工：刨(bao)(bao)(bao)(bao)削(xue)(xue)加(jia)(jia)(jia)工一般指(zhi)在刨(bao)(bao)(bao)(bao)床上利(li)用(yong)(yong)刨(bao)(bao)(bao)(bao)刀相對(dui)于(yu)(yu)(yu)工件做往復直線運(yun)動(dong)，切除(chu)多余材料的(de)加(jia)(jia)(jia)工方法(fa)。刨(bao)(bao)(bao)(bao)削(xue)(xue)加(jia)(jia)(jia)工時，刀具的(de)往復直線運(yun)動(dong)為(wei)切削(xue)(xue)主(zhu)運(yun)動(dong)。因此，刨(bao)(bao)(bao)(bao)削(xue)(xue)加(jia)(jia)(jia)工速度慢，生產率較低。刨(bao)(bao)(bao)(bao)削(xue)(xue)加(jia)(jia)(jia)工比銑(xian)削(xue)(xue)加(jia)(jia)(jia)工平(ping)(ping)(ping)穩(wen)，刨(bao)(bao)(bao)(bao)削(xue)(xue)加(jia)(jia)(jia)工屬(shu)粗(cu)加(jia)(jia)(jia)工，個別情況(kuang)下可達到半精(jing)加(jia)(jia)(jia)工程度，其精(jing)度低于(yu)(yu)(yu)銑(xian)削(xue)(xue)加(jia)(jia)(jia)工，其加(jia)(jia)(jia)工精(jing)度一般可達IT8—IT7，表(biao)面(mian)粗(cu)糙度為(wei)Ra6.3—1.6μm，精(jing)刨(bao)(bao)(bao)(bao)平(ping)(ping)(ping)面(mian)度可達0.02/1000，表(biao)面(mian)粗(cu)糙度為(wei)0.8—0.4μm。但對(dui)于(yu)(yu)(yu)大型(xing)鑄件的(de)加(jia)(jia)(jia)工具有(you)優越(yue)性。適用(yong)(yong)范圍(wei)：刨(bao)(bao)(bao)(bao)平(ping)(ping)(ping)面(mian)、刨(bao)(bao)(bao)(bao)垂(chui)直面(mian)、刨(bao)(bao)(bao)(bao)臺階面(mian)、刨(bao)(bao)(bao)(bao)直角溝(gou)槽(cao)(cao)、刨(bao)(bao)(bao)(bao)斜(xie)面(mian)、刨(bao)(bao)(bao)(bao)燕尾槽(cao)(cao)、刨(bao)(bao)(bao)(bao)丁型(xing)槽(cao)(cao)、刨(bao)(bao)(bao)(bao)V型(xing)槽(cao)(cao)、刨(bao)(bao)(bao)(bao)曲面(mian)、刨(bao)(bao)(bao)(bao)孔內鍵槽(cao)(cao)、刨(bao)(bao)(bao)(bao)齒條(tiao)、刨(bao)(bao)(bao)(bao)復合表(biao)面(mian)。對(dui)于(yu)(yu)(yu)相對(dui)較軟的(de)材料來說，工件強度不像硬材料那(nei)么嚴格的(de)要求(qiu)，所以塑料機(ji)械(xie)加(jia)(jia)(jia)工周期(qi)相對(dui)來說較短。濱江(jiang)區(qu)五(wu)金(jin)機(ji)械(xie)加(jia)(jia)(jia)工多少錢(qian)
