The 3M 51119 60-0000-1234-8 58308 661x Imperial 0.5 um Diamond Lapping Film is a high-performance abrasive film designed for precise and efficient material removal in various applications. This film features a 3-mil (0.008125 cm) thick petroleum jelly backed polyester film with a 0.5-micron (0.000005 cm) diameter, 60-grit, 58308 661x Imperial diamond abrasive particles.
The 0.5-micron particles in this lapping film offer a very fine abrasive grain size, making it suitable for finishing and polishing applications where a high degree of surface finish and accuracy is required. The 60-grit abrasive particle size ensures that this film can effectively remove material quickly and efficiently, making it an excellent choice for production environments and large-scale projects.
The 3-mil thick petroleum jelly backed polyester film provides excellent adhesion to the workpiece, ensuring consistent contact between the abrasive particles and the material being lapped. The petroleum jelly backing also helps to prevent scratches and swirl marks on the workpiece, resulting in a smooth and uniform finish.
The 58308 661x Imperial designation refers to the specific size and shape of the film, which is available in various sizes to accommodate different workpiece geometries and lapping machine configurations. The imperial measurement system used in this designation allows for easy compatibility with standard imperial measurement tools and machines commonly used in the United States and other English-speaking countries.
Overall, the 3M 51119 60-0000-1234-8 58308 661x Imperial 0.5 um Diamond Lapping Film is a versatile and effective abrasive solution for a wide range of material finishing and polishing applications, offering a high degree of precision, efficiency, and surface finish quality.
