Machining the workpiece in separate processes not only slows down the machining speed of the workpiece but also increases the workload of workers, which can no longer meet the requirements of efficient and accurate machining of workpieces in modern production.

[0003] After retrieval, in the Chinese utility model patent publication No. CN205271030U, an internal cooling forming tool for machining the inner hole of a high-pressure joint is disclosed. It integrates reaming, machining forming, and orifice chamfering, combines multiple functions on one tool. When machining a workpiece, multiple processes are realized at one time, avoiding the cumbersome process of manual tool change, reducing the workload, and improving work efficiency. However, the above-mentioned tool is integrated. When the cutting edge is damaged, the whole needs to be replaced, and the damaged cutting edge cannot be replaced alone, resulting in waste of resources and increased replacement costs. Therefore, an internal cooling forming tool with replaceable cutting edges is needed. Content of the Utility Model
