SURFACE ROUGHNESS SPECIMEN

A Surface Roughness Specimen Set typically includes a collection of standardreference samples that represent different levels of surface roughness. Thisspecific set with 30 pieces provides a comprehensive range of roughness valuesto help users visually and tactilely compare and evaluate the surface finish ofmaterials. These specimen sets are commonly used in machining, manufacturing,and quality control to ensure that the surface finish meets specific industrystandards and requirements.

• For checking, identifying and specifying the roughness by symbol
• Accuracy: -17% ~ +12%

Benefits:

• Quick and Convenient: Provides an immediate visual andtactile reference for comparing surface finishes, making it easy to evaluateroughness without needing expensive equipment.
• Versatile and Comprehensive: With 30 specimens, userscan reference a wide range of roughness values and machining types, cateringto diverse industry requirements.
• Cost-Effective: Allows for surface finish assessmentwithout the need for sophisticated instruments, which can be expensive andrequire specialized training to operate.

A surface roughness specimen set with 30 pieces is a practical tool foranyone involved in quality assurance, machining, or product development whoneeds a reliable and accessible way to assess and verify surface finishesaccording to industry standards.

Key Features:

• Variety of Roughness Levels: The set usually includes 30 specimens that cover a wide range of roughness values, often expressed in micrometers (µm) or microinches (µin). These values might range from very smooth (e.g., 0.05 µm Ra) to relatively rough (e.g., 25 µm Ra), giving users an extensive selection of roughness levels.
• Standardized Finishes: Specimens in these sets are made according to standardized surface finishing processes, such as grinding, milling, turning, and lapping. This allows for consistent and repeatable comparisons with real-world surface finishes.
• Durable Materials: Specimens are typically made from hardened steel, which ensures that the samples are durable and can withstand frequent handling without changing their roughness characteristics over time.
• Marked Identification: Each specimen is marked with its corresponding roughness value and sometimes the type of machining process used to achieve that finish. This allows for easy identification and quick reference during inspections.
• Portable Case: These sets often come in a protective case, which keeps the specimens organized and protected during transport or storage. The case may include slots or labeling for each piece, ensuring that they remain well-organized and easy to locate.
