The common methods of gear processing mainly include milling teeth, hobbing teeth and grinding teeth, which have the following characteristics: Milling teeth: Characteristics: through the multi-edge cutting mode of the milling cutter, the tooth profile is gradually cut out. Advantages: High production efficiency, suitable for mass production; High machining precision, can obtain better surface quality; A wide range of gears can be machined. Gear hobbing: Features: Through the special hob and gear template or gear bar meshing, using the rotation of the hob to achieve gear processing. Advantages: fast processing speed, suitable for mass production; High machining precision, can obtain better tooth shape and dimensional accuracy; Good surface quality of the gear is conducive to improving the meshing performance of the gear. Grinding: Features: The tooth profile of the gear is processed through the grinding process, and the common grinding methods include rolling grinding and grinding. Advantages: High machining precision, can obtain excellent tooth shape and dimensional accuracy; The surface quality of the gear is excellent, which is conducive to improving the meshing performance of the gear. Suitable for high precision requirements, large modulus or special gear tooth shape. It should be noted that different gear machining methods are suitable for different gear types and machining requirements. In practical applications, the appropriate processing method should be selected according to the specific gear specifications, quantity, quality requirements and processing equipment conditions.
