DHL FREE Surface Roughness Comparison Sample Block 30 Blocks Ra0.05-12.5mm

Description: Surface Roughness Comparison Sample Block Notebook Sample 30 Blocks Ra0.05-12.5mm Roughness Sample Block This is a visual and tactile, a comparative method to check the mechanical parts machined surface roughness of a measuring tool. By comparing the visual and magnifying mirror with the machined workpiece, the surface roughness level can be judged, which can provide guidance for designers on the intuitive sense and appearance features of the specific processing methods and roughness grades, and can also be used as the visual aids for mechanical majors in Colleges and universities. Its characteristic parameter is the arithmetic mean deviation Ra of the surface profile. It fully conforms to the national standard GB6060.2-85 and national verification regulations JJG102 technical requirements. It is made of 45# high quality carbon structural steel. It is advanced in technology, stable in quality, complete in variety and specification, high in hardness, good in wear resistance and never rusty. It is especially suitable for production site. Matters needing attention in use and maintenance： In the use of the parts should be as much as possible and under the same conditions (including surface color, lighting conditions, etc.) shall not hand contact with the sample block, strict rust treatment, rust prevention, and avoid scratches.
