Coated abrasives (sandpaper) are imperative in various industrial areas, including the automotive and the metal industry. An exact outcome is often highly appreciated in abrasion processes, which means that the wear process must be precisely controlled. In this paper, a new method for analyzing the grinding process of coated abrasives is proposed. In order to study the grinding properties of sandpaper, a tribology cell was connected to a rheometer. The experiments consisted of unlubricated (dry) steel balls-on-disc experiments on coated abrasive with aluminum oxide grains. The friction and wear data showed that the rheometer equipped with a tribology cell can be used to measure different tribological parameters, such as the friction coefficient and the Gap. The wear process was investigated over a range of abrasive grain sizes (9–40 µm) and a variety of different loads (1–10 N). Results from these experiments showed that the abrasive wear increased with increasing particle size and normal load. Hence, it is proposed that this method is a reliable approach for investigating the wear process of coated abrasives.

涂层磨料（砂纸）在包括汽车和金属工业在内的各个工业领域都是必不可少的。通常在磨损过程中会获得精确的结果，这意味着必须精确控制磨损过程。本文提出了一种分析涂层磨料磨削过程的新方法。为了研究砂纸的研磨性能，将一个摩擦学单元连接到流变仪上。实验包括对带有氧化铝颗粒的涂层磨料的未润滑（干式）圆盘钢球实验。摩擦和磨损数据表明，配备有摩擦学单元的流变仪可用于测量不同的摩擦学参数，例如摩擦系数和间隙。在一系列磨料粒度（9–40 µm）和各种不同负载（1–10 N）下研究了磨损过程。这些实验的结果表明，随着粒度和法向载荷的增加，磨料的磨损也会增加。因此，提出该方法是研究涂覆磨料的磨损过程的可靠方法。
