2、 Next is the non-metallic material machinery manufacturing industry

With the development and trend of high-tech, more and more new materials are being used in production processes, such as porcelain, plastic, and polyethylene. Nowadays, some rolling bearings are produced and processed using unique structural ceramics, while valve accessories are also made using polyethylene raw materials. The portable eddy current flaw detector for ultrasonic welding seam detection is made of hard raw materials, and some applications can replace metal composite materials to make product workpieces. Its surface roughness must also be inspected during the production and manufacturing process.

3、 Other industries

With the strong strengthening and improvement of the technology and function of roughness meters, as well as their deep marketing promotion and application, more and more fields have been found to require roughness inspection. In addition to mechanical processing and manufacturing, power engineering, communication, electronic devices, such as network switches, integrated circuit chips, semiconductor materials, and other production and processing processes also require roughness identification. Even stationery, kitchenware, and human teeth surfaces used in daily life must be tested for surface roughness.
