金屬表面加工技術是一種能夠改善金屬材料外觀和性能的關鍵過程。在金屬產品製造的過程中，噴砂和研磨拋光是常見的金屬表面加工方法，並且它們常常被同時應用以達到更好的效果。
噴砂過程是通過在金屬表面噴射高壓氣流中懸浮的磨料顆粒，以達到消除污垢、凹陷和划痕的目的。這種技術不僅能夠清理金屬表面，還能改善其粗糙度，從而提高金屬件的外觀質量和耐腐蝕性。噴砂金屬表面噴砂也可以增加金屬材料的粘附性，使其更容易被涂層材料附著。
研磨拋光是通過在金屬表面應用研磨材料，如砂輪或研磨毛刷，以去除粗糙度、平整表面和創造光滑的光澤。這個過程可通過手動或機械化進行，可以適應不同形狀和尺寸的金屬產品，從而實現高品質的表面加工效果。研磨拋光還可以去除金屬表面的銹垢和氧化物，以提升金屬製品的耐久性和美觀度。
金屬表面加工在金屬製品製造中起著非常重要的作用。在噴砂和研磨拋光過程中，工匠們根據產品的需要和要求來選擇適當的技術。通過這些表面加工技術，金屬製品可以達到更高的質量標準，並具有更好的耐久性和視覺效果。

Title: Metal Surface Processing Techniques and Their Application in Metal Product Manufacturing
Article:
Metal surface processing techniques are crucial processes that can improve the appearance and performance of metal materials. In the process of metal product manufacturing, sandblasting and polishing are common methods of metal surface processing, and they are often applied together to achieve better results.
The sandblasting process involves the projection of abrasive particles suspended in high-pressure air onto the metal surface to eliminate dirt, dents, and scratches. This technique not only cleans the metal surface but also improves its roughness, thereby enhancing the visual quality and corrosion resistance of the metal parts. Sandblasting metal surfaces can also increase the adhesion of the metal material, making it easier for coating materials to adhere.
Polishing is the application of grinding materials, such as grinding wheels or polishing brushes, on the metal surface to remove roughness, create a smooth finish, and enhance its overall shine. This process can be done manually or mechanized, and it can accommodate different shapes and sizes of metal products, resulting in high-quality surface finishing. Polishing also removes rust and oxides from the metal surface, improving the durability and aesthetics of metal products.
Metal surface processing plays a vital role in metal product manufacturing. During the sandblasting and polishing processes, craftsmen select appropriate techniques based on the needs and requirements of the products. With these surface processing techniques, metal products can meet higher quality standards and have improved durability and visual effects.
