Rougness Tester Applicaition:
The surface quality is one of the most important characteristics. It is in a high position in metrology. People used to make
a general assessment of the surface Roughness with standard specimen by observing with eyes or touching with hand.
As the progress of manufacture technology, the demand for the quality of the processing surface is getting higher and higher.
And so is the gauge used for testing surface roughness, nowadays, in all of the testers the pot-ball surface roughness tester, which is quicker, more convenient and more accurate, is most wildly used.
In China, as the development of manufacturing technology, there will be more and more industries engaged in the testing
and assessment of surface, so the surface roughness, as one of the effective indexes, is not only be used in every domain
but also has a high prospect.
