Choosing the right steel grit is key to ensuring the cleaning effect of the shot blasting machine. Here are some steps and considerations:
1. Workpiece material and cleaning requirements: First, determine the material of the workpiece to be cleaned and the cleaning requirements. Different workpieces and requirements may require different types of steel grit. For example, steel shot is suitable for cleaning steel surfaces, while glass beads are suitable for light cleaning and workpieces with high surface finish requirements.
2. Material of steel grit: Different steel grits have different hardness, shape and cleaning characteristics. For example, steel shot has high cleaning ability and durability.
4. Supplier advice: Communicate with the shot blasting machine supplier to get their advice and opinions. They usually have rich experience and can provide useful guidance based on the workpiece and cleaning requirements.
5. Cost and economy: Consider the cost and economy of the shot blasting media. The prices of different steel grits may be different, so it is necessary to comprehensively consider the balance between cleaning effect and cost.
