A machining method for a high-precision large rectangular spline shaft comprises the first step of machining pretreatment, the second step of rough machining of the spline shaft, the third step of rough milling of the spline shaft, the fourth step of finish machining of the spline shaft, the fifth step of semi-finish milling of the spline, the sixth step of finish milling of the spline and the seventh step of polishing. In the machining process, the indexing precision of the spline shaft on the milling machine is guaranteed through the indexing tool. According to the design, high-precision machining can be conducted on the large spline shaft through a common floor mill, production of the high-precision large spline shaft is achieved, the production and machining cost is reduced, the indexing precision during rough milling can be guaranteed through the indexing tool, dependence on a high-precision indexing plate is reduced, and the machining cost is effectively reduced. 一种高精度大型矩形花键轴的加工方法，包括第一步加工预处理步骤、第二步粗加工花键轴
