With the high precision requirements of parts processing requirements, the requirements for the processing environment are becoming more and more stringent. Only the effects of the impact of precision parts on the fluctuation of gas pressure fluctuations, ambient temperature changes, external and self -vibration analysis, and the factors of precision parts processing factors. There are many influences. In order to improve the accuracy of super precision processing, we must not only understand the impact of the factors, but also master solutions.
1. Adjust the mechanical adjustment, first tighten the wire lock and tighten the nut. , Re -precision with shovel, so that the contact surface dyeing point is more than 80%, and the 0.02mm plug ruler is not entered into qualification.
Second, check the tight or loose of the silk nut. Adjust the premature force and check the axial rotation value to make the error of not more than 0.005mm.
Third, check the end surface of the wire nut and the binding surface of the binding, combined with over looseness, repair and adjustment, and repair.
Fourth, the roller screw manufacturing error is large or axis. The automatic compensation with the control system can also eliminate the gap. Use the instrument to measure and adjust the screw to move. Insufficient lubricating oil or no lubricating oil from each guide surface.
