Methods for improving accuracy in measuring deviations from roundness and cylindricity

Abstract

The problem of improving the technical level and quality of industrial products is now one of the most important tasks. The performance of machining workstation, machines and instruments depends on the quality of production of parts and assemblies and the accuracy of their connections. Precision parameters play a special role in machine tool construction and instrumental production of parts for the aerospace industry. In machines, the value of the torque transmitted by the spindle of the metal cutting machine to the tool, the durability of roller conical bearings, as well as the tightness of connections, the strength of press fits, the correctness of centering on conical surfaces, the accuracy of kinematic pairs and circuits, especially in the spindles of precision CNC machines, which significantly affects the quality of the manufactured products.
