Surface Roughness Standards Set, Surface Finish Comparator Set, 30 Specimens with Ra0.05-12.5mm ,30pcs Surface Roughness Comparison Sample Block
As an important quality control, in manufacturing and engineering fields, ensuring that the surface roughness of components meets requirements is crucial. Using the standard set helps monitor and control the surface quality of products to meet quality standards.
- 【Multiple Roughness Grades】The standard set typically includes a range of samples with 30 levels of roughness.
- 【Stability & Durability】These standard sets are made of 45# carbon structural steel which is stable and durable materials to ensure accuracy and reliability during long-term and repeated use.
- 【Instrument Calibration】Surface roughness instruments (such as surface roughness testers) need periodic calibration to ensure the accuracy of their measurement results.
- 【Warm Tips】In the use of the parts to be examined and should try to be in the same conditions, including surface color, lighting conditions. No direct contact with the hands to compare the sample block, strict anti-rust treatment to prevent rust and corrosion, and avoid touching scratches.
- 【Widely Used】It's not only to play a critical role in surface roughness measurement, quality control, and instrument calibration, but also be used as a visual teaching aid for mechanical majors in colleges and universities.
