[0002] The gear blank processing platform generally adopts gear hobbing and rotation processing. During the gear hobbing process, the blank needs to be fixed and the file is rotated along the edge of the blank. If the fixation is not firm, the processing will be displaced, resulting in inaccurate number of teeth and affecting the processing quality.
