[0002] The existing grinding methods of multi-tooth and high-precision straight-tooth rat tooth discs (parallelism within 0.01 and scale within 6") all adopt the method of sequential grinding of single teeth with commonly used vitrified bond grinding wheels. In the last fine grinding, In order to prevent the impact of grinding wheel loss on the accuracy, the method of dressing the grinding wheel multiple times in each cycle (for example: 360-tooth rathirth plate, repairing once every 30 teeth) is adopted in the middle. Although the shape of the grinding wheel is repaired, it also causes The positioning accuracy of the machine tool has brought errors to the grinding position and shape

Embodiment 1
[0031] Embodiment 1: as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, a high-precision straight-toothed Hirth grinding method is mainly to solve the problem of the parallelism of the Hirth (one set) installation base surface, and to meet the assembly accuracy of the machine tool. To process parts of this unit: 20LH91404 (144 teeth) rat tooth plate figure 1 For example:
[0032] As long as the existing equipment remains unchanged, the machining accuracy of the hirth plate can be improved only by making small changes to the program.
[0033] The machine tool system used in the present invention is SIEMENS 840D, and most of the programs used by the machine tool are modular programs such as Figure 6 ~ Figure 9 shown. The processing program used in the present invention is obtained by combining each module program and researching and setting key parameters.
[0034] The indexing cycle subroutine is briefly introduced as follows:

The invention discloses a high-precision straight-toothed hirth coupling grinding processing method and belongs to the technical field of mechanical cold processing. The high-precision straight-toothed hirth coupling grinding processing method comprises the following steps: preparing a tool, a grinding wheel and programming before grinding processing; regulating and aligning the tool, aligning and clamping a workpiece, and determining a coordinate system; carrying out trial cutting on an initial workpiece; officially performing grinding processing, and carrying out trans-teeth grinding; and checking. The high-precision straight-toothed hirth coupling grinding processing method has the advantages of being superior to the traditional processing method, improving the processing accuracy of a hirth coupling and realizing domestication of high-precision hirth couplings.
