A74 supports quality management and meets diverse polishing needs with long-lasting performance.

In the manufacturing industry's quality control, uniformity and durability of product surface finishing are required. Particularly in the polishing of metal parts and printed circuit boards, the removal of fine scratches and burrs, as well as ensuring smoothness, are essential for the reliability and functionality of the products. Inadequate polishing can lead to early deterioration and performance decline of the products. A74 achieves long lifespan through the formulation settings of the polishing material, making it suitable for polishing that requires smoothness. Therefore, it contributes to the improvement of quality control in manufacturing. 【Usage Scenarios】 - Polishing of stainless steel, copper plates, and printed circuit boards (PCBs) - Surface treatment of metals and non-ferrous metals - Deburring of working tools 【Effects of Implementation】 - Extended lifespan due to formulation settings of the polishing material - Compatible with narrow to wide belts - Finishing suitable for polishing that requires smoothness - Usable as a disc as well
