The general method is to clamp the gear ring and then use a gear milling machine to mill the gear. However, the traditional clamping method is often difficult to accurately center, which causes the milled product to be offset, resulting in an increase in the scrap rate and cost. Therefore, a planetary gear milling fixture is proposed. Utility Model Content
