（一）工件涂鍍、工件粘接前處理
噴砂能把工件表面的銹皮等一切污物清除，并在工件表面建立起重要的基礎(chǔ)圖式（即通常所謂的毛面），而且可以通過調(diào)換不同粒度的磨料，達(dá)到不同程度的粗糙度，大大提高工件與涂料、鍍料的結(jié)合力?；蚴拐辰蛹辰永喂蹋|(zhì)量好。
Sandblasting to scale on the surface of the workpiece and all dirt removed, and on the base of workpiece surface it is very important to build schemata (usually the so-called hair side), but also by changing different particle size of abrasive, to varying degrees of roughness, greatly improve the workpiece and the adhesion strength of the coating, plating materials. Or make adhesive bonding stronger, better quality.
（二）鑄鍛件毛面、熱處理后工件的清理與拋光
噴砂能清理鑄鍛件、熱處理后工件表面的一切污物（如氧化皮、油污等殘留物），并將工件表面拋光提高工件的光潔度，起到美化工件的作用。
噴砂清理能使工件露出均勻一致的金屬本色，使工件外表美觀，達(dá)到美化裝飾的作用。
Sandblasting can clean up all the dirt on the surface of the casting, heat treatment after forging workpiece (such as scale, oil residue), and improve the finish of workpiece, the workpiece surface polishing beautification artifacts.
Sand blasting can make the metal workpiece with uniform is ecru, make workpiece appearance more beautiful, achieve beautification adornment effect.
（三）機(jī)加工件毛刺清理與表面美化
噴砂能清理工件表面的微小毛刺，并使工件表面加平整，消除了毛刺的危害，提高了工件的檔次。并且噴砂能在工件表面交界處打出小的圓角，使工件顯得加美觀、加精密。
Sandblasting can clean up the small burr on the surface of the workpiece, and make the surface more smooth, eliminate the dangers of the burr, improve the level of the workpiece. And sand can in workpiece surface junction with small rounded corners, make artifacts appear more beautiful, more precise.
（四）改善零件的機(jī)械性能
機(jī)械零件經(jīng)噴砂后，能在零件表面產(chǎn)生均勻細(xì)微的凹凸面（基礎(chǔ)圖式），使?jié)櫥偷玫酱鎯?chǔ)，從而使?jié)櫥瑮l件改善，并減少噪聲提高機(jī)械使用壽命。
Mechanical parts after sandblasting, can produce even subtle in parts surface concave and convex surface (basic schema), the lubricating oil storage, so that improve lubrication condition, and improve the service life of the mechanical to reduce noise.
（五）光飾作用
1、對(duì)各種工件表面拋光，使工件表面美觀。
2、使工件達(dá)到光滑又不反光要求。
對(duì)于某些特殊用途工件，噴砂可隨意實(shí)現(xiàn)不同的反光或亞光。如不銹鋼工件、木制家具表面亞光化，磨砂玻璃表面的花紋圖案,以及布料表面的毛化加工等。
For some special purpose artifacts, sandblasting can achieve different reflective or inferior smooth. Inferior smooth, wooden furniture, such as stainless steel workpiece surface, the surface of the ground glass decorative pattern design, and roughen the processing on the surface of the fabric.
（六）消除應(yīng)力及表面強(qiáng)化
通過砂丸敲擊工件表面，消除應(yīng)力，增加工件表面強(qiáng)度，如彈簧、機(jī)加工刀具和飛機(jī)葉片等工件的表面處理。
Through the sand pill on the workpiece surface, eliminating stress, increase the surface strength, such as spring, machining tool and workpiece surface treatment such as plane blade
