Ways to improve the specific fit accuracy of precision parts machining plant


Precision shaft machining plant to improve the specific fit accuracy of the bearing installation, it is necessary to use the measurement method and tools to avoid bearing deformation. For bearing bore volume bearing bore and bore fit surface specifications, all measurement items of relevant inner diameter and outer diameter can be measured. And the measured data to make a comprehensive analysis, as the basis, for precision with the shaft and seat hole bearing mounting position specifications. When measuring the corresponding dimensions and geometry of the shaft and seat bore, the measurement should be performed under the same temperature conditions as the bearing measurement. In order to ensure a strong and specific fit, the roughness of the shaft and the seat hole should be as small as possible.


In the above measurement, precision parts processing factory should be in the bearing bore and bore, as well as the corresponding surface of the shaft and seat hole, near the installation of the chamfer on both sides, each can show the larger error orientation of the 2 groups of signs, to facilitate the specific installation, so that the error of the two sides of the match in the same direction. In this way, the errors of both sides are partially offset after installation.
