The present invention relates to a milling manufacturing process for a small saw blade with a width of 0.5-1.8mm. The teeth are opened by milling, and the teeth are opened by
purchasing bright steel strips and self-made special steel strips on multiple single-tooth continuous micro-saw milling machines; for tooth division, the push rod first advances two tooth pitches, and clamps through the tooth back clamp plate, and the push rod is operated to reset. When the left tooth division knife is pushed to the right or the right tooth division knife is pushed to the left, the teeth tilt left and right, and then the tooth division knife is reset, and the tooth back clamp plate is relaxed, and the push rod is repeatedly operated to advance two tooth pitches; heat treatment, an
electric heating tubular furnace is used, the inner opening of the tube is 18mm in
diameter, and the inner liner is a
quartz glass tube;
tempering to determine the color, placed in an air furnace, semi-automatic nailing, including an upper pin
assembly and a steel strip milling
assembly. Beneficial effect: According to the actual situation of the teeth after milling, in order to reduce the deflection during sawing, the left and right tooth division amounts can be adjusted at any time, and the sharpness of the two sides of the saw blade can be consistent when touched, which is a problem that other tooth divisions cannot solve flexibly and randomly.
