After the thermal spraying process of the product is completed, the roughness of the product surface is detected to meet the needs of the customers

Roughness instrument is also called surface roughness instrument, surface finish instrument, surface roughness tester, roughness measuring instrument, roughness meter, roughness tester and other names. It has the characteristics of high precision, wide range of measurement, easy operation, easy to carry and stable work. It can be widely used in the detection of various metal and non-metallic surface. The instrument is a pocket instrument integrated with the sensor host, with the characteristics of hand-held and more suitable for use in the production site. The shape design is durable and has remarkable anti electromagnetic interference capability, which conforms to the new design trend. The application fields of roughness instrument are as follows:

1、 The machining and manufacturing industry is mainly metal processing and manufacturing. The roughness instrument was originally produced to detect the surface roughness of machined parts. Especially, the contact type roughness measuring instrument is suitable for the detection of hard metal surface. For example: automobile parts processing and manufacturing, mechanical parts processing and manufacturing, etc. As long as the surface quality of workpiece is involved in these manufacturing industries, it is necessary for the application of roughness instrument.

2、 With the development of science and technology, more and more new materials are applied to processing technology, such as ceramics, plastics, polyethylene, etc. some bearings are processed and manufactured with special ceramic materials, and pump valves are made of polyethylene materials. These materials are hard in texture, and some applications can replace metal materials to make workpieces. In the process of production and processing, the surface roughness of these materials should be tested.

3、 With the continuous enhancement and improvement of the technology and function of roughness instrument, and the in-depth promotion and application, more and more industries are found to require roughness detection. Besides machining and manufacturing, the roughness evaluation is also required in the production and processing of power, communication, electronics, such as coupling on switch and integrated circuit semi conductor, Even stationery, tableware and human tooth surface used in people's life need to be tested by surface roughness
