Quality control

Resource, precision control, smooth motion of ball-screws mainly depends on the constancy of the internal diameter, profile and thread surface hardness. Mainly used in ball-screws are radius and arched profiles thread. Modern methods of metrological control can ensure the quality of the materials used in production, as well as the measurement of roughness, parameters of thread, control of kinetic precision of ball-screws.
One of these methods used by our company, is a method of measuring profile. The measuring system allows to control the roughness and the thread profile with a resolution of 1nm. After processing the data obtained from this system on a computer, we can see the thread profile and the accumulated error in pitch and in case of deviation from the thread preset parameters, we can immediately make a correction in the CNC machine tool.
