Gear Accuracy Before Shaving

- Aug 21, 2020-

The accuracy of pre-shaving gear has a great influence on the machining accuracy after shaving. Generally speaking, the gear accuracy requirement before shaving should be one level lower than that after shaving, and the requirement for pitch is relatively high. Because the machine tool has no transmission chain and is not forced to drive, the ability to correct the accumulated error of tooth pitch is relatively poor. Therefore, in general, hobbing rather than gear shaping is used in the pre-shaving process as much as possible
