The characteristics of precision shaft, guide rod manufacturers to explain for you
Guide rodThe manufacturer thinksThe formulation of precision machining process route is to formulate the overall layout of the process. The main task is to select the processing method of each appearance, determine the processing sequence of each appearance, and the number of jobs in the entire processing process.
Guide rodThe manufacturer thinksThe main surface of various precision hardware shaft parts is the cylindrical surface of each journal, the inner hole accuracy of the hollow shaft is generally not high, and the precision hardware shaft on the thread, spline, keyway and other secondary surface accuracy requirements are also very high. Therefore, the processing route of shaft parts mainly considers the processing sequence of cylindrical parts, and the processing of quadric surfaces is reasonably interspersed. The following describes a variety of precision hardware shaft parts processing routes and production of commonly used materials:
Guide rodThe manufacturer thinksFor general precision hardware shaft parts, fine grinding is sufficient to ensure the quality of processing. Precision shaft parts in addition to finishing, should also be arranged jing processing. For shaft parts other than the overall quenching, the finishing process can be arranged before the quenching heat treatment or after the quenching heat treatment and before the secondary surface processing according to the specific situation.
Guide rodThe manufacturer thinksIt should be noted that after quenching, ordinary tools and shaft parts can not be used. Guide rodThe manufacturer thinksThe main surface of each journal is cylindrical, the inner hole accuracy of the hollow shaft is generally not high, and the accuracy requirements of the thread, spline, keyway and other secondary surfaces on the precision spindle are also very high. Therefore, the processing route of shaft parts mainly considers the processing sequence of cylindrical parts, and the processing of quadric surfaces is reasonably interspersed.
Guide rodThe manufacturer thinksAs the core component of power transmission, the shaft is widely used in servo motors, household appliances, automobiles, industrial robots and other fields. The machining accuracy of the shaft will cause uncontrollable transmission disturbances such as rotation eccentricity and axial movement, which will reduce the service life and transmission accuracy of the equipment. Guide rodThe manufacturer thinksControlling the dimensional accuracy, geometric accuracy and mutual position accuracy in the process of shaft machining is the premise to ensure the precise transmission of the mechanism. At present, multi-function CNC machine tools can be used to achieve high-precision machining of shaft dimensions, and the machining accuracy can reach0.001mm ~ 0.0015mm, but due to the inevitable wear of turning tools in continuous processing, it is impossible to control the size fluctuation. It is necessary to manually use a micrometer to repeatedly measure and manually correct the machine tool parameters, which consumes manpower, and the measurement error caused by human experience and measurement position will be introduced into processing.
Guide rodThe manufacturer thinksAxis size precision online intelligent detection equipment can establish processing files for each precision axis in the processing process, build industrial interconnection between processing and detection, meet the construction needs of enterprise intelligent manufacturing, industrial Internet of Things, industrial big data, and provide more processing guarantee and data support for processing enterprises.
