刨(bao)(bao)削(xue)(xue)的工(gong)艺特点：生产(chan)效率较(jiao)低(di)：刨(bao)(bao)削(xue)(xue)的主运(yun)动(dong)为(wei)往复直(zhi)线运(yun)动(dong)，加(jia)之刀(dao)(dao)具切(qie)(qie)入和切(qie)(qie)出时(shi)(shi)(shi)有反(fan)向冲击时(shi)(shi)(shi)受惯(guan)性力的影(ying)响，一个表面(mian)(mian)往往要(yao)限制了(le)切(qie)(qie)加(jia)工(gong)精度(du)(du)(du)不(bu)高(gao)：刨(bao)(bao)削(xue)(xue)的精度(du)(du)(du)可(ke)达IT8～IT7，表面(mian)(mian)粗糙(cao)度(du)(du)(du)为(wei)Ra1.6～6.3μm。但当采(cai)用宽(kuan)刀(dao)(dao)精刨(bao)(bao)时(shi)(shi)(shi)，即在(zai)龙(long)门刨(bao)(bao)床上进行多件(jian)(jian)或多刀(dao)(dao)加(jia)工(gong)时(shi)(shi)(shi)，用宽(kuan)刃(ren)刨(bao)(bao)刀(dao)(dao)以很(hen)低(di)的切(qie)(qie)削(xue)(xue)速度(du)(du)(du)，切(qie)(qie)去工(gong)件(jian)(jian)表面(mian)(mian)上一层极薄的金(jin)属，平(ping)面(mian)(mian)度(du)(du)(du)不(bu)大于0.02/1000，表面(mian)(mian)粗糙(cao)度(du)(du)(du)Ra0.4～0.8μm。削(xue)(xue)速度(du)(du)(du)的提高(gao)。单刃(ren)刨(bao)(bao)刀(dao)(dao)实际(ji)参(can)加(jia)的切(qie)(qie)削(xue)(xue)刃(ren)长度(du)(du)(du)有限，经过多次行程(cheng)才(cai)能(neng)加(jia)工(gong)进去，加(jia)工(gong)不(bu)连续(xu)基本工(gong)艺时(shi)(shi)(shi)间较(jiao)长，刨(bao)(bao)刀(dao)(dao)返(fan)回行程(cheng)时(shi)(shi)(shi)不(bu)进行切(qie)(qie)削(xue)(xue)。对于机械(xie)加(jia)工(gong)件(jian)(jian)的材料选择，一要(yao)从(cong)实用性的方面(mian)(mian)考虑，包括要(yao)了(le)解材料的硬(ying)度(du)(du)(du)、表面(mian)(mian)粗糙(cao)度(du)(du)(du)、导电导热等性能(neng)。浙江非标零件(jian)(jian)机械(xie)加(jia)工(gong)有哪些(xie)厂家(jia)

机械(xie)加工(gong)(gong)方(fang)法和适(shi)用范围应该怎(zen)么选择呢？铣(xian)(xian)(xian)(xian)(xian)削(xue)加工(gong)(gong)：（1）顺铣(xian)(xian)(xian)(xian)(xian)：铣(xian)(xian)(xian)(xian)(xian)削(xue)力(li)的(de)水平分力(li)与工(gong)(gong)件(jian)的(de)进(jin)(jin)给(ji)方(fang)向相同，工(gong)(gong)件(jian)台进(jin)(jin)给(ji)丝杠与固定螺母之间(jian)一(yi)般有间(jian)隙存(cun)在(zai)，因(yin)此切削(xue)力(li)容易引(yin)起(qi)工(gong)(gong)件(jian)和工(gong)(gong)作(zuo)台一(yi)起(qi)向前窜动，使进(jin)(jin)给(ji)量突然(ran)增(zeng)大(da)，引(yin)起(qi)打(da)刀。在(zai)铣(xian)(xian)(xian)(xian)(xian)削(xue)铸(zhu)件(jian)或锻件(jian)等(deng)表(biao)面(mian)有硬(ying)度的(de)工(gong)(gong)件(jian)时(shi)，顺铣(xian)(xian)(xian)(xian)(xian)刀齿(chi)首先接触(chu)工(gong)(gong)件(jian)硬(ying)皮(pi)，加剧了铣(xian)(xian)(xian)(xian)(xian)刀的(de)磨损(sun)。（2）逆(ni)(ni)铣(xian)(xian)(xian)(xian)(xian)：可以避免顺铣(xian)(xian)(xian)(xian)(xian)时(shi)发生的(de)窜动现象。逆(ni)(ni)铣(xian)(xian)(xian)(xian)(xian)时(shi)，切削(xue)厚度从零开始(shi)逐渐增(zeng)大(da)，因(yin)而(er)刀刃(ren)开始(shi)经历(li)了一(yi)段在(zai)切削(xue)硬(ying)化(hua)的(de)已加工(gong)(gong)表(biao)面(mian)上挤压(ya)滑(hua)行的(de)阶段，加速了刀具的(de)磨损(sun)。同时(shi)，逆(ni)(ni)铣(xian)(xian)(xian)(xian)(xian)时(shi)，铣(xian)(xian)(xian)(xian)(xian)削(xue)力(li)将工(gong)(gong)件(jian)上抬，易引(yin)起(qi)振动，这是逆(ni)(ni)铣(xian)(xian)(xian)(xian)(xian)的(de)不利之处。适(shi)用范围：铣(xian)(xian)(xian)(xian)(xian)平面(mian)、铣(xian)(xian)(xian)(xian)(xian)台阶、铣(xian)(xian)(xian)(xian)(xian)沟槽、铣(xian)(xian)(xian)(xian)(xian)成形面(mian)、铣(xian)(xian)(xian)(xian)(xian)螺旋(xuan)槽、铣(xian)(xian)(xian)(xian)(xian)齿(chi)轮、切断拱墅区(qu)五金配件(jian)机械(xie)加工(gong)(gong)怎(zen)么报价(jia)机械(xie)加工(gong)(gong)在(zai)编程时(shi)需(xu)要注意(yi)哪些问题？确定合理的(de)切削(xue)用量。

机(ji)(ji)械(xie)加工应如何选(xuan)择毛坯料?1.铸(zhu)(zhu)(zhu)件(jian)：形状复杂(za)的(de)零件(jian)毛坯，宜采(cai)(cai)用(yong)(yong)铸(zhu)(zhu)(zhu)造(zao)(zao)(zao)方(fang)法(fa)制造(zao)(zao)(zao)。目前(qian)铸(zhu)(zhu)(zhu)件(jian)大(da)(da)多用(yong)(yong)砂型(xing)铸(zhu)(zhu)(zhu)造(zao)(zao)(zao)，它(ta)又分为木模(mo)手工造(zao)(zao)(zao)型(xing)和金(jin)属模(mo)机(ji)(ji)器造(zao)(zao)(zao)型(xing)。木模(mo)手工造(zao)(zao)(zao)型(xing)铸(zhu)(zhu)(zhu)件(jian)精度低，加工表面余(yu)量(liang)大(da)(da)，生(sheng)产(chan)效率(lv)(lv)低，适用(yong)(yong)于(yu)单(dan)件(jian)小(xiao)批生(sheng)产(chan)或大(da)(da)型(xing)零件(jian)的(de)铸(zhu)(zhu)(zhu)造(zao)(zao)(zao)。金(jin)属模(mo)机(ji)(ji)器造(zao)(zao)(zao)型(xing)生(sheng)产(chan)率(lv)(lv)高，铸(zhu)(zhu)(zhu)件(jian)精度高，但设备费用(yong)(yong)高，铸(zhu)(zhu)(zhu)件(jian)的(de)重(zhong)量(liang)也受到(dao)限制，适用(yong)(yong)于(yu)大(da)(da)批量(liang)生(sheng)产(chan)的(de)中(zhong)小(xiao)铸(zhu)(zhu)(zhu)件(jian)。其次，少(shao)量(liang)质量(liang)要求(qiu)较高的(de)小(xiao)型(xing)铸(zhu)(zhu)(zhu)件(jian)可采(cai)(cai)用(yong)(yong)特(te)种铸(zhu)(zhu)(zhu)造(zao)(zao)(zao)，如压力(li)铸(zhu)(zhu)(zhu)造(zao)(zao)(zao)、离心制造(zao)(zao)(zao)和熔(rong)模(mo)铸(zhu)(zhu)(zhu)造(zao)(zao)(zao)等。2.焊(han)接(jie)件(jian)：焊(han)接(jie)件(jian)是用(yong)(yong)焊(han)接(jie)方(fang)法(fa)而获得的(de)结合件(jian)，焊(han)接(jie)的(de)优点是制造(zao)(zao)(zao)简单(dan)，周期短，节省材料，缺点是抗振性差(cha)，变形大(da)(da)，需经时效处理后(hou)才能(neng)进行机(ji)(ji)械(xie)加工。

常用(yong)机械加(jia)工(gong)(gong)方(fang)式及特(te)点：刨(bao)(bao)削(xue)：定义：刨(bao)(bao)刀与工(gong)(gong)件作水平(ping)方(fang)向相对直线往复运动的(de)(de)(de)切(qie)削(xue)加(jia)工(gong)(gong)方(fang)法(fa)。刨(bao)(bao)削(xue)是平(ping)面(mian)加(jia)工(gong)(gong)的(de)(de)(de)主要(yao)方(fang)法(fa)之(zhi)一，是单件小批量生(sheng)产的(de)(de)(de)平(ping)面(mian)加(jia)工(gong)(gong)较常用(yong)的(de)(de)(de)加(jia)工(gong)(gong)方(fang)法(fa)。常见(jian)的(de)(de)(de)刨(bao)(bao)床(chuang)类机床(chuang)有牛(niu)头(tou)刨(bao)(bao)床(chuang)、龙门(men)刨(bao)(bao)床(chuang)和(he)插床(chuang)等。刨(bao)(bao)削(xue)的(de)(de)(de)工(gong)(gong)艺特(te)点：通用(yong)性好：根据(ju)切(qie)削(xue)运动和(he)具体的(de)(de)(de)加(jia)工(gong)(gong)要(yao)求。价格低，刨(bao)(bao)床(chuang)的(de)(de)(de)结构比(bi)车(che)床(chuang)、铣床(chuang)简单。调整和(he)操作也较方(fang)便。所(suo)用(yong)的(de)(de)(de)单刃刨(bao)(bao)刀与车(che)刀基本相同。制造刃磨(mo)和(he)安装皆较方(fang)便，形状简单，可加(jia)工(gong)(gong)垂(chui)直、水平(ping)的(de)(de)(de)平(ping)面(mian)，还(hai)可加(jia)工(gong)(gong)T型槽(cao)(cao)、V型槽(cao)(cao)、燕尾槽(cao)(cao)等。机械产品的(de)(de)(de)工(gong)(gong)艺过程又可分为铸造、锻造、冲压、焊接、机械加(jia)工(gong)(gong)、热处理、装配、涂装等工(gong)(gong)艺过程。
