Surface Roughness Stand Comparator (6pcs Horizontal milling Ra0.4-12.5mm)

It can measure the roughness of six processing methods (horizontal milling, vertical milling, turning, plain grinding, flat lapping, external grinding). Able to perform a variety of functions such as measurement of different types of surfaces, inspection of various textures, etc. Not only suitable for surface roughness measurement, quality control and instrument calibration, it is also a visual teaching aid for mechanical majors in colleges and universities, meeting various application needs in different industries and fields

• The notebook sample block contains standards for the six most important processing methods among the popular "AA" values. All samples were calibrated with uAA (arithmetic mean) and metric equivalent um Ra.
