The NG-CoreGrind 2000 achieves a surface fineness of Ra3.2, which refers to the roughness average, a measure of the smoothness of the specimen’s surface after grinding. A Ra3.2 value indicates that the surface is sufficiently smooth for accurate testing, particularly in mechanical and compressive strength assessments. This level of fineness is necessary in order to ensure consistent contact during testing, preventing irregularities that could lead to inaccurate results.

The surface fineness of Ra3.2 indicates that the NG-CoreGrind 2000 can produce high-quality finishes, which is an ideal solution for laboratories that require precise, smooth surfaces on their rock or concrete specimens for reliable and repeatable testing outcomes.
