When selecting surface processing methods for the mandrel, the following aspects should be considered:
- When mandrels choose surface processing methods in practice, it is necessary to consider the structural shape, size, material, and heat treatment requirements comprehensively.
- The precise surface of the mandrel is achieved step by step through rough machining, semi-finishing, and finishing. Merely selecting the final processing method based on quality requirements is insufficient. It is also essential to correctly determine the processing route from the blank to the final shape.
- When selecting surface processing methods for the mandrel, in addition to ensuring quality requirements, considerations should also include production efficiency and economic requirements. For mass production, it is advisable to use efficient advanced processing methods as much as possible. For example, for internal holes and flat surfaces, turning can be used instead of conventional milling, planing, and boring methods.
