北京机械加工厂浅谈机械加工的分类

北京机械加工厂_今天谈一下机械加工的分类。

何为机(ji)(ji)械(xie)(xie)(xie)加(jia)(jia)工(gong)呢(ni)?从广意(yi)上(shang)讲(jiang),机(ji)(ji)械(xie)(xie)(xie)加(jia)(jia)工(gong)就是凡能用机(ji)(ji)械(xie)(xie)(xie)手段制造(zao)产品的(de)过(guo)(guo)程;狭(xia)意(yi)上(shang)讲(jiang),就是用车床(chuang)、铣床(chuang)、钻床(chuang)、磨床(chuang)、冲压机(ji)(ji)、压铸(zhu)机(ji)(ji)机(ji)(ji)等专用机(ji)(ji)械(xie)(xie)(xie)设(she)备制作(zuo)零件(jian)的(de)过(guo)(guo)程。我(wo)们通常(chang)指的(de)机(ji)(ji)械(xie)(xie)(xie)加(jia)(jia)工(gong)是一种(zhong)用加(jia)(jia)工(gong)机(ji)(ji)械(xie)(xie)(xie)对工(gong)件(jian)的(de)外形尺寸或性能进行改变的(de)过(guo)(guo)程。

按被加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)的(de)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)件(jian)处于的(de)温度(du)状态(tai)﹐分(fen)为(wei)冷(leng)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)和热(re)(re)(re)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)。所谓冷(leng)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)一般是指(zhi)在(zai)常(chang)温下加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong),并且不引起工(gong)(gong)(gong)(gong)(gong)(gong)(gong)件(jian)的(de)化(hua)学或物相变化(hua)﹐我们称为(wei)冷(leng)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)。冷(leng)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)按加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)方式的(de)差别又可分(fen)为(wei)切削加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)和压力加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)。而热(re)(re)(re)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)一般是指(zhi)在(zai)高于或低于常(chang)温状态(tai)的(de)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)﹐会引起工(gong)(gong)(gong)(gong)(gong)(gong)(gong)件(jian)的(de)化(hua)学或物相变化(hua)﹐我们称为(wei)热(re)(re)(re)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)。热(re)(re)(re)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)常(chang)见(jian)的(de)有(you)热(re)(re)(re)处理﹐煅造﹐铸造和焊接等(deng)几种。 

机械加工集中体现在一下几种方式:精密焊接、灯丝电源绕组、激光切割、金属粘结、金属拉拔、等离子切割、辊轧成型、重型加工、金属板材弯曲成型、模锻、水喷射切割等。
