冷拔鋼加工必須在專門的冷拔機(jī)上才能完成。加工流程一般必須經(jīng)由以下環(huán)節(jié)：1、材料處理。采用冷拔材料產(chǎn)品的都是對材料的尺寸精度有較要求的應(yīng)用環(huán)境，冷拔加工能通過對材料的尺寸選擇來決定加工后產(chǎn)品尺寸精度和表面光亮度，一般均選擇比需要的產(chǎn)品外徑尺寸大幾毫米的材料來加工。因此，為了使原材料能經(jīng)過冷拔模具，原材料必須經(jīng)過處理。處理的方式是使用**的機(jī)械將原材料的一端碾壓得比模具孔徑小。2、拉拔加工。原材料經(jīng)過前期處理后，就可以上冷拔機(jī)進(jìn)行拉拔加工。為了減少拉拔模具的損耗，在這個(gè)過程必須對模具進(jìn)行潤滑。潤滑的方法一般有二種，一種為油潤滑，一種為**潤滑材料潤滑。3、加工。經(jīng)拉拔后產(chǎn)品還需要進(jìn)行調(diào)直加工、去除夾頭廢料加工、定尺剪切、防銹處理等環(huán)節(jié)才算***成品。冷拔圓鋼應(yīng)該范圍很廣，多應(yīng)用在五金配件、家電配件、加工原材料，機(jī)加工等等各種熱軋圓鋼滿足不了要求的領(lǐng)域。
