Network optimization information:
The machining error caused by spindle rotation error varies with different machining methods. The radial rotation error of spindle can cause roundness and cylindricity error of workpiece when machining outer circle and inner hole, but it has no direct effect on the machining of workpiece end face. The axial rotation error has little influence on the outer circle and inner hole, but has great influence on the perpendicularity and flatness of the end face; In the process of thread turning, the main axis deviation can cause the periodic error of thread lead. In the process of machining, properly improving the machining accuracy of spindle and box, selecting second-hand CNC machine tools to recycle high-precision bearings, improving the assembly accuracy of spindle components, balancing high-speed spindle components, preloading rolling bearings, etc. can improve the rotation accuracy of machine tool spindle.
Then there is the guide error, which is the judgment basis of the relative position relationship of the machine parts on the machine tool, and also the basis of the machine tool movement. The accuracy requirements of the machine tool guide mainly include three aspects: the straightness in the horizontal plane, the straightness in the vertical plane, and the parallelism (torsion) of the front and rear guide rails.
In addition to the manufacturing error of the guide rail itself, the heterogeneous wear and installation quality of the guide rail are also important factors causing the recovery error of the second-hand machine tool. The wear of guide is an important reason for the decline of machine tool accuracy. In addition, there is the error at the end of the transmission chain, which refers to the relative motion error between the transmission elements at both ends of the transmission chain, and is usually measured by the angle error at the end of the transmission chain.
