Roughness Tester China Manufacturer Roughness Analyzer Surface Roughness Gauge Principle of instrumental
The instrument is cartesian coordinate measuring method, stylus contact type. Axis X uses high-precision linear guide rail as the benchmark, axis Z1 uses digital sensor to map the coordinate points of the surface contour shape of the measured parts, and carries out mathematical operation and processing on the original data collected by the sensor through computer software to mark the required measurement items.
