Sander

The grinding machine drives the grinding wheel to rotate at high speed through an electric motor, utilizing friction between the abrasive material and the surface of the tested material to remove surface substances or prepare samples with specific roughness. It is used in fields such as coating adhesion testing, metal surface treatment, and plastic wear resistance detection, enabling the quantification of a material's surface resistance to wear.
Selection
When selecting, match the material hardness with the grinding wheel grit size—use coarse wheels for soft materials and fine wheels for hard materials. Consider the compatibility of the sample size with the equipment workbench, and ensure the motor power meets the required rotational speed standards. Regularly check the balance of the grinding wheel and ensure that safety protection devices are intact.
