Features:
1: This vertical roughness comparator kit includes 4 distinct samples with different roughness values (RA0.8-6.3). It provides clear options for precise evaluation and easy differentiation between various finishes, supporting you in selecting the most suitable quality for your technical requirements.
2: Capable of assessing textures across 7 processing methods—lathe, vertical milling, flat milling, flat grinding, external grinding, grinding, and planer—this comparator meets a broad range of inspection and testing needs for industrial environments.
3: Made of 45 carbon steel, each sample is built for resistance against deformation and equipped with a protective oil film to help maintain accuracy through frequent and prolonged use. The robust material and manufacturing processes dependable operation in different applications.
4: An organized and clearly labeled comparison chart makes identification of each roughness grade straightforward. The model reference is easy to find and all samples are arranged in an orderly fashion for efficient on-site usage.
