工作原理：

電動(dòng)機(jī)帶動(dòng)安裝在拋光機(jī)上的砂帶或砂輪拋光盤高速旋轉(zhuǎn)，由于拋光盤和拋光輪共同作用并與待拋表面進(jìn)行摩擦，進(jìn) 而可達(dá)到去除漆面污染、氧化層、淺痕的目的。

(1) 除去鑄件、鍛件熱處理后零件表面的氧化皮。

(2) 除去零件表面上的銹蝕積碳、焊渣、舊漆層或其它干燥了的油類物質(zhì)。

(3) 提高零件表面的光潔度，以提高產(chǎn)品的美觀度。

(4) 除去零件的毛刺或方向磨痕。

按動(dòng)力來(lái)源有氣動(dòng)和電動(dòng)兩種。氣動(dòng)式比較安全，但需要?dú)庠?；電?dòng)式容易解決電源問題，但一定要注意用電安全。

按功能分有雙功能工業(yè)用磨砂/拋光機(jī)和簡(jiǎn)易型拋光機(jī)兩種。雙功能工業(yè)用磨砂拋光機(jī)能安上砂輪打磨金屬材料，又能 換上拋光盤做車漆護(hù)埋。此機(jī)較重，為2-3kg,但工作起來(lái)非常平穩(wěn)，不易損壞。

The motor drives the abrasive belt or grinding wheel polishing disc installed on the polishing machine to rotate at a high speed. As the polishing disc and the polishing wheel work together and rub against the surface to be polished, the purpose of removing paint pollution, oxide layer and shallow marks can be achieved.

(1) Remove the scale on the surface of parts after heat treatment of castings and forgings.

(2) Remove the corroded carbon deposit, welding slag, old paint layer or other dried oil substances on the surface of the parts. 

(3)  Improve the surface smoothness of parts to improve the aesthetics of products. 

(4)  Remove burrs or directional wear marks of parts. According to the power source, there are pneumatic and electric. Pneumatic is safer, but it needs an air source; Electric is easy to solve the power supply problem, but we must pay attention to the safety of electricity use. According to functions, there are two kinds of dual-function industrial sanding/polishing machines and simple polishing machines. Dual-function industrial abrasive polishing machine can be equipped with grinding wheels to polish metal materials, and can be replaced with polishing discs to protect and bury car paint. This machine is heavy, 2-3kg, but it works smoothly and is not easy to be damaged.
