[0004] When this structure is in use, it has excellent strength, hardness and wear resistance by adopting PCD blades and blade arrangement design. However, this structure is not easy to adjust the stroke appropriately according to needs when in use, which can easily cause limitations during processing, and it is not easy to replace different cutter heads according to needs, which is not convenient when in use. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-performance compression PCD corn milling cutter, aiming to solve the problems raised in the above-mentioned background technology.
