Exterior Surfaces Roughness Comparison Sample Block Set, 30-Piece Inspection Gage for Measuring Ra0.05-12.5 µm Finishes

Specifications:This exterior roughness comparator set is designed to facilitate accurate evaluation of mechanical workpiece finishes by direct comparison. The set enables both visual and microscopic assessment, supporting precise determination of exterior texture for quality control and inspection tasks.Features:The RUG-100 notebook sample block includes standard samples for six main processing methods: turning, end milling, flat milling, exterior grinding, external grinding, and polishing. Each of the 30 included samples is calibrated for arithmetic mean value () and metric Ra (µm), covering key roughness grades widely used in engineering environments.The set provides a reliable reference for comparing 30 exterior finish samples, each fixed in a composite bag for easy handling. The flat grinding standards include 2, 4, and 8 finishes, with each sample measuring approximately 7/8" x 3/8". Every sample is crafted to accurately represent the tactile and visual characteristics of machined s, allowing users to better understand the result of different machining processes.Designed for fast and straightforward comparison, these samples comply with S.A.E specifications to reliable performance during technical inspections. The complete set is enclosed in a compact wallet-sized case (dimensions: 6 x 3 x 3/8 inches, estimated), weighing approximately 14 ounces for convenient portability.The package includes:1 set of 30 calibrated roughness sample blocks
