Non-metal processing manufacturing industry. With the advancement and development of science and technology, more and more new materials are applied to processing technology, such as ceramics, plastics, polyethylene, etc. Some bearings are now made of special ceramic materials. , and pumps, valves, etc. are made of polyethylene materials. These materials are hard and can replace metal materials in making workpieces in some applications. Their surface roughness also needs to be detected during production and processing.
As the technology and functions of roughness meters continue to be strengthened and improved, as well as in-depth promotion and application, more and more industries are found to require roughness testing. In addition to mechanical processing and manufacturing, electric power, communications, electronics, For example, roughness assessment is also required during the production and processing of couplings on switches, integrated circuit semiconductors, etc. Even the surface of stationery, tableware, and human teeth used in people’s lives require surface roughness inspection.
