Technical Field

[0001] The utility model relates to the technical field of milling machine processing, in particular to a milling machine chamfering tooling for special-shaped parts. Background Art

[0002] When a milling machine processes special-shaped workpieces, there is often a problem of unstable clamping. Therefore, special fixtures that match the special-shaped parts are often required for special-shaped parts. If the output of special-shaped parts is small, the cost of the special fixture will rise rapidly, which is extremely uneconomical for enterprises. And because the processing volume of special-shaped parts is large, the most widely used workpiece chamfering processing is particularly important. Therefore, the technical personnel in this field provide a milling machine chamfering tooling for special-shaped parts to solve the problems raised in the above background art. Summary of the Utility Model
