8mm的(de)(de)硬黃銅板(ban)將(jiang)其用M4埋(mai)頭(tou)螺釘緊固到鉗口上(shang)，形成的(de)(de)軟鉗口。這樣還可以保護零件被夾壞，還具有互換性。數(shu)(shu)控(kong)加(jia)工(gong)中(zhong)(zhong)常用的(de)(de)小(xiao)竅門：1、在機械(xie)加(jia)工(gong)中(zhong)(zhong)用磁(ci)鐵吸取小(xiao)零件(費(fei)件)吸和取都不方便。可在磁(ci)鐵的(de)(de)下(xia)面(mian)吸一個(ge)鐵板(ban)，數(shu)(shu)控(kong)沖(chong)床加(jia)工(gong)廠，不但可以吸很多小(xiao)件，而(er)且將(jiang)鐵板(ban)拉開(kai)小(xiao)件會立即自(zi)動傾入收集箱(xiang)內(nei)。2、在機械(xie)加(jia)工(gong)中(zhong)(zhong)的(de)(de)皮帶輪傳動時皮帶輪經常和輪軸之(zhi)間(jian)打(da)(da)滑，在輪軸上(shang)用15~18mm劃窩(wo)鉆頭(tou)劃一系列窩(wo)，這樣可以形成吸附力防止打(da)(da)滑。

CNC加工(gong)(gong)數(shu)(shu)控車(che)床(chuang)加工(gong)(gong)便(bian)于新(xin)產(chan)(chan)品(pin)研(yan)制(zhi)(zhi)和改(gai)型(xing)。CNC加工(gong)(gong)數(shu)(shu)控車(che)床(chuang)加工(gong)(gong)一(yi)般不(bu)需(xu)要很多復(fu)雜的工(gong)(gong)藝裝備(bei)，通過編(bian)制(zhi)(zhi)加工(gong)(gong)程序(xu)(procedure)就可把(ba)形狀復(fu)雜和精度(du)（精1確度(du)）要求(qiu)較高的零件加工(gong)(gong)出來，當產(chan)(chan)品(pin)改(gai)型(xing)，更改(gai)設計時，只要改(gai)變(bian)程序(xu)，而不(bu)需(xu)要重新(xin)設計工(gong)(gong)裝。所以，CNC加工(gong)(gong)數(shu)(shu)控車(che)床(chuang)加工(gong)(gong)能大大縮短產(chan)(chan)品(pin)研(yan)制(zhi)(zhi)周期，安徽(hui)數(shu)(shu)控加工(gong)(gong)，為新(xin)產(chan)(chan)品(pin)的研(yan)制(zhi)(zhi)開發、產(chan)(chan)品(pin)的改(gai)進、改(gai)型(xing)提(ti)供了捷(jie)徑。

數控加工(gong)(gong)確定進給速度(du)(du)(du)的原則(ze)：(1)當(dang)工(gong)(gong)件的質(zhi)量要求(qiu)能夠(gou)保證時(shi)，為(wei)提高生產效率(lv)，可選(xuan)擇較(jiao)高的進給速度(du)(du)(du)。一(yi)般(ban)(ban)在100-200mm/min范(fan)(fan)(fan)圍內選(xuan)取(qu)(qu)。(2)在刀斷(duan)、加工(gong)(gong)深孔或用(yong)高速鋼1刀具(ju)加工(gong)(gong)時(shi)，宜(yi)選(xuan)擇較(jiao)低的進給速度(du)(du)(du)，一(yi)般(ban)(ban)在20-50mm/min范(fan)(fan)(fan)圍內選(xuan)取(qu)(qu)。(3)當(dang)加工(gong)(gong)精度(du)(du)(du)、表面(mian)粗糙度(du)(du)(du)要求(qiu)高時(shi)，進給速度(du)(du)(du)應選(xuan)小些(xie)，一(yi)般(ban)(ban)在20-5Omm/min范(fan)(fan)(fan)圍內選(xuan)取(qu)(qu)。
