The application fields of roughness meter are:

First, mechanical processing manufacturing industry, mainly metal processing and manufacturing. Roughness meter was originally produced to detect the surface roughness of machined parts. In particular, the stylus roughness measuring instrument is suitable for the detection of hard metal surface. Such as: auto parts processing manufacturing, machinery parts processing manufacturing and so on. As long as these processing and manufacturing industries involve the workpiece surface quality, it is essential for the detection application of roughness meter.

Second, non-metallic processing manufacturing industry, with the progress and development of science and technology, more and more new materials are applied to the processing technology, such as ceramics, plastics, polyethylene, and so on, now some bearings are processed with special ceramic materials, and pump valves are processed with polyethylene materials. These materials are hard and can replace metal materials to make workpieces in some applications. The surface roughness also needs to be tested in the production and processing process.

Three, with the continuous strengthening and improvement of the technology and function of the roughness instrument, as well as in-depth promotion and application, more and more industries are found to demand roughness detection, in addition to mechanical processing and manufacturing, power, communication, electronics, such as the coupling on the switch, integrated circuit semiconductor production process also need roughness evaluation, Even the stationery used in people's life, tableware, the surface of people's teeth all need to use the surface roughness test.以上翻译结果来自有道神经网络翻译（YNMT）· 通用领域
