What is Sand Blasting (Bead blast)?
Sand blasting (also named bead blast) is a very common kind of surface finish used for CNC machining aluminum parts.Sandblasting is process of smoothing and cleaning a hard surface by forcing solid particles across that surface at high speeds using compressed air. People usually use mesh to decide the size for the sand blasting.
| Mesh | μm | mm |
|---|---|---|
| 5 | 3900 | 3.9 |
| 8 | 2500 | 2.5 |

Benefits for Sand Blasting (Bead blast)?
(1)Sandblasting cleans the surface. One of the reasons why sandblasting is an important part of the finishing process isn’t just because it smooths the surface of the object. It cleans the surface, too.
(2)Sandblasting services are a great way to remove rust, oil, and harmful contaminants from almost any kind of surface. Sandblasting is surprisingly fast. Sandblasting cleans and smooths objects for finishing quickly and efficiently. This makes cleaning tough surfaces like metal easier, which saves on time and money.
(3)Sandblasting services remove old paint. When an object has old paint covering it, sandblasting can quickly remove the paint at a high speed. This prepares the object for a new coating of paint with a fresh and smooth result.
