The surface roughness of the coupling refers to the small spacing and small peak and valley unevenness of the machined surface.The distance (wave distance) between the two wave crests or two wave troughs is very small (below 1mm), and it is difficult to distinguish with the naked eye, so it belongs to the microscopic geometric shape error.The smaller the surface roughness, the smoother the surface.The surface roughness has a great influence on the performance of mechanical parts.
