ZHEJIANG HESHUO TECHNOLOGY CO.,LTD , https://www.hosuocn.com When we process the standard sprocket, we use the combined fixture technology to assemble a set of profiling fixtures, and use the vertical milling machine and the common end mill to profil the tooth shape. The effect is better. The machining of the tooth is divided into two steps: Φ100mm inner hole positioning, clamped on the rotary table (replaced by the circular base plate), according to the number of workpiece teeth, the pitch radius r1 of the groove is drilled into a hole on the indexing circle of the workpiece, and then the contour clamp is applied. Profile processing r2, r3 arc and straight line. The knot of the profiling fixture
