The mechanical manufacturing industry, mostly the manufacture of metal.

The primary function of roughness tester is testing the surface roughness of processing parts especially the pot-ball roughness tester is adept to testing the hard surface. For example the automobile parts manufacturing, mechanical parts manufacturing, etc. the roughness tester is essential in every manufacturing industry engaged in quality of parts surface.

The manufacturing of Non-metal. As the development of science and technology, more and more new materials are used in manufacturing techniques, for example, pottery, plastic, polyethylene, etc. now some bearings are made in special pottery, and some pump valves are made in polyethylene. These materials all have firm character, and some of them can be made into parts instead of metal. Their surface roughness also needs testing in manufacture

Besides the mechanical processing, surface roughness testing is also used in electric power, communication and electron, so much as stationery, dishware etc.
