What are the machining methods of micro gearbox gears? The gear box industry can be divided into three categories: hobbing, forming and space forming. The specific methods are as follows:
1. Rolling cutting method. In addition to cutting and feeding movements, rolling cutting tools also roll compared with gear machining. Its characteristic is that only one tool is needed to process micro gearbox with the same modulus and variation. Rolling cutting method can be divided into continuous rolling cutting method and dividing rolling cutting method.
2. Forming method. This method does not generate motion. It uses a tool with a slot profile shape to move in the direction of the gear profile, and the tool contacts the gear along the entire profile line. Therefore, the machine tool used is simpler than the rolling cutting method. The forming method can be divided into indexing forming method and full tooth forming method.
3. Space forming method. In this method, the full space female die with gear shape is used as the die. The entire micro gearbox gear is cast and sintered in this mold. Pressed or die cast. It is suitable for mass production of small gears made of non-ferrous metals and plastics.
