Background technique

In order to detect the surface roughness of the workpiece, a special surface roughness meter has appeared on the market. The working principle of the surface roughness meter is: when the stylus is directly across the measured surface of the workpiece, due to the peak and valley fluctuations of the measured surface contour, the stylus will move up and down in the direction perpendicular to the measured contour surface. This movement amplifies the signal through the electronic device, and then outputs the data or graphics related to the roughness through the zero meter or other output devices, and finally measures the surface roughness of the workpiece.

The surface roughness meter currently on the market is usually a hand-held surface roughness meter.
