[0002] The fixtures used for processing the reducer housing play a vital role in the manufacturing process. They ensure the accurate positioning and stable clamping of the housing, thereby improving the processing accuracy and efficiency. The clamping fixture is used to clamp the housing for milling, drilling, turning and other processing. These fixtures usually have adjustable clamping force to ensure the stability and safety of the housing during processing.
