In the past, when we pulled the inner hole of the gear blank on the broaching machine, we used the steel ball limit clamp. The cutting force was concentrated on the steel ball during broaching, because the hardness of the steel ball was higher than that of the shank, after multiple broaching It was found that there was a dent in the contact between the shank and the steel ball. The broach often stuck, and the hammer was shaken to exit, which affected the life of the broach and the chuck. So, we designed a fast broach chuck.
