Above all, a Nuo company draws lessons from foreign X model, XR, S, wave etc blade, to broach each geometry angle has thorough research, develop and made AHNO-S get model standard. This getting key assures the cutting function of broach, pass aggrandizement point, the stability that assures blade ministry intensity and life and can anticipate a gender. Through be opposite at the same time point curve tries fractionize, the blade inside research, outside blade and transfer the position of circular arc of S form R and size, assure the ability breaking bits of this type broach adequately. Next, form of chamfer of broach of research of development of A Nuo company. Broach chamfer form is crucial to the ability discharging bits of broach. When studying groovy body, used the method of development of numerical control software and union of photograph of figuration emery wheel, shortened development is periodic, reduced cost of research and development greatly. Still have, a Nuo company is chance with development of connecting rod broach, evolve 2 times through groovy form helix angle with improve, acquired the DS8900-P puissant bit with superior performance, suit hard data particularly (HRC42-48) auger cut, farther fill the blank that our country exceeds hard data aperture to machine.
