總的來說和噴砂處理意思差不多，只不過，噴砂處理需要氣動(dong)(dong)源(yuan)做為動(dong)(dong)力，而拋(pao)(pao)(pao)丸(wan)(wan)(wan)處(chu)理是靠電動(dong)(dong)馬達帶動(dong)(dong)拋(pao)(pao)(pao)丸(wan)(wan)(wan)器(qi)，當鋼丸(wan)(wan)(wan)/鐵丸(wan)(wan)(wan)落入(ru)到拋(pao)(pao)(pao)丸(wan)(wan)(wan)器(qi)合(he)頁上(shang)時，鋼丸(wan)(wan)(wan)/鐵丸(wan)(wan)(wan)就會被拋(pao)(pao)(pao)射出(chu)去打到待拋(pao)(pao)(pao)丸(wan)(wan)(wan)處(chu)理的(de)物(wu)體上(shang)，整個過(guo)程稱之為拋(pao)(pao)(pao)丸(wan)(wan)(wan)處(chu)理。

     拋丸(wan)(wan)處理(li)（以下簡稱(cheng)為拋丸(wan)(wan)）是(shi)一(yi)種機(ji)(ji)械方面的(de)(de)表面處理(li)工(gong)藝(yi)的(de)(de)名(ming)稱(cheng)，類(lei)似(si)的(de)(de)工(gong)藝(yi)還有噴砂處理(li)和噴丸(wan)(wan)處理(li)。拋丸(wan)(wan)的(de)(de)原(yuan)理(li)是(shi)用電動機(ji)(ji)帶動葉輪(lun)體旋(xuan)轉(直接帶動或用V型皮帶傳動)，靠離(li)心力的(de)(de)作用，將(jiang)直徑(jing)約在0.2～3.0的(de)(de)彈丸(wan)(wan)(有鑄鋼(gang)丸(wan)(wan)、鋼(gang)絲切(qie)丸(wan)(wan)、不銹鋼(gang)丸(wan)(wan)等(deng)不同類(lei)型)拋向工(gong)件(jian)(jian)(jian)(jian)(jian)(jian)的(de)(de)表面，使工(gong)件(jian)(jian)(jian)(jian)(jian)(jian)的(de)(de)表面達到一(yi)定的(de)(de)粗造(zao)度，使工(gong)件(jian)(jian)(jian)(jian)(jian)(jian)變得美觀，或者改變工(gong)件(jian)(jian)(jian)(jian)(jian)(jian)的(de)(de)焊接拉應(ying)力為壓(ya)應(ying)力，提(ti)高工(gong)件(jian)(jian)(jian)(jian)(jian)(jian)的(de)(de)使用壽命。通過(guo)提(ti)高工(gong)件(jian)(jian)(jian)(jian)(jian)(jian)表面的(de)(de)粗糙(cao)度，也提(ti)高了工(gong)件(jian)(jian)(jian)(jian)(jian)(jian)后續噴漆的(de)(de)漆膜附著力。拋丸(wan)(wan)這種工(gong)藝(yi)幾乎用于機(ji)(ji)械的(de)(de)大(da)多數領域，如修造(zao)船(chuan)、汽車零(ling)部(bu)件(jian)(jian)(jian)(jian)(jian)(jian)、飛機(ji)(ji)部(bu)件(jian)(jian)(jian)(jian)(jian)(jian)、槍炮坦克(ke)表面、橋梁、鋼(gang)結構、玻璃、鋼(gang)板型材、管道(dao)內外(wai)壁(bi)防腐甚至道(dao)路(lu)表面等(deng)等(deng)行業。

     拋丸處理區別與噴砂處理的本質：為一個表面粗糙，一個表面細膩。
