我单位在铣床加工直齿圆锥齿轮时,通常采用的是传统的三刀法加工,用的刀具也是刃具厂家生产的国家标准的三刀法盘形铣刀。用三刀法加工直齿圆锥齿轮时,当找好工件中心加工到齿的切削深度后,还要进行左右偏移,把大端多余的部分铣去,才能达到齿的厚度要求。这样的加工方法既费时间又不容易保证齿的中心,还可能出现倒齿,特别是初学铣床的操作者更不容易掌握好左右偏移量 When machining flat spur bevel gears in milling machines, I usually use the traditional three-blade machining method. The tools used are also the national standard three-blade disk cutter produced by the cutting tool manufacturers. When machining a straight bevel bevel gear with the three-point method, when finding the depth of the workpiece to be machined to the depth of the tooth, the left-right offset should also be carried out to mill the excess part of the large-end to achieve the thickness requirement of the tooth. This method of processing time and not easy to ensure the center of the tooth, but also may appear inverted teeth, especially beginner milling machine operator is not easy to grasp the left and right offset
