Application of Roughness Tester in Automotive Industry.
The automotive industry, including the processing and manufacturing of complete machines and parts, must use the roughness tester.
For example, the evaluation and detection of the honed surface of the cylinder liner/body surface processing technology platform of the heart part of the automobile engine and the detection have always been one of the technical difficulties faced by the cylinder liner processing industry.

Surface Roughness Ra, Rz, Ry
Ra-- in the sampling length L within the outline of the arithmetic mean of the absolute value of the offset
Rz-- within the sampling length and average value of the five largest profile peak height and the average of the five largest outline of a deep valley.
Ry-- between sampling length L within peak contour lines and contour line from the bottom.
