噴(pen)砂(sha)(sha)(sha)是(shi)一種工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)面處(chu)理(li)工(gong)(gong)(gong)藝。以壓縮(suo)空氣(qi)為動力，形成高速噴(pen)射(she)(she)束，將噴(pen)射(she)(she)的(de)材料(liao)(liao)（銅礦石、石英砂(sha)(sha)(sha)、金剛砂(sha)(sha)(sha)、鐵砂(sha)(sha)(sha)、海砂(sha)(sha)(sha)）高速噴(pen)射(she)(she)到待處(chu)理(li)工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)面，從而改變工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)面的(de)外觀或形狀。由于磨(mo)料(liao)(liao)對工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)面的(de)沖擊和切(qie)割作(zuo)用，工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)面可以獲得一定的(de)清潔度和不同的(de)粗糙度。
