1. Select the appropriate sandblasting material and sandblaster model based on the hardness of the material being processed and the desired degree of polish.
2. The abrasive must be clean and have a high grit size. Impurities and excessive fine powder must be avoided, as this will reduce the polishing effect.
3. Wear protective glasses and a mask when operating a sandblaster to avoid breathing abrasive and harmful fumes.
4. Maintain an appropriate distance and blasting angle when operating the sandblaster to avoid direct impact and scratches on the material.
5. Clean and maintain the sandblaster after use to ensure its service life.
