Why is the tooth shape of broach oblique?
Because the broaching method of broach is done by layer by layer, the required inner spline shape is eventually machined out. Therefore, the blade of the broach is tilted from front to back
The tooth is made oblique in order to make the broaching cutter tooth is smooth, continuous in withdrawing from participation in the cutting, does not appear at the same time the whole circle cutter tooth cut, and the exit, so as to avoid broaching in appeared in the process of broaching flickering phenomenon, so as to obtain good cutting surface, too to improve the service life of the broach broach. But make oblique to the high cost.
Landlord said broach is not a saw, one is mechanical cutting forming processing, a manual cutting, how will the same? Made oblique should be angled in order to make the cutting tooth with the cutting plane, the plane like a razor blade.
