Short gear shaft efficient machining method

The invention relates to the technical field of gear milling and gear grinding in the machinery manufacturing industry, in particular to a high-efficiency machining method for a short gear shaft. In the existing processing methods, most short gear shaft workpieces need to be ground after tooth milling, but in the process of tooth milling and gear grinding, due to the short workpiece, it cannot be directly processed due to the limitation of the machining range of the machine tool. The workpiece must be lengthened to a position where the radius of the hob or the grinding wheel can be released before the normal processing of the workpiece can be carried out. After the workpiece is processed, the lengthened part is removed, which wastes both man-hours and materials. The invention provides a high-efficiency machining method for a short gear shaft, which thoroughly solves the above-mentioned problems of waste of materials and man-hours. The method utilizes the extended part to process two parts at a time, which not only reduces the cost, but also improves the production efficiency.
