Description

Technical Field

[0001] The utility model relates to the technical field of milling processing, in particular to a milling part processing tool. Background Art

[0002] Milling refers to the use of a rotating multi-edged tool to cut the workpiece. It is a highly efficient processing method. During operation, the tool rotates and the workpiece moves. The workpiece can also be fixed, but the rotating tool must also move. When processing the workpiece, in order to ensure the firmness of the workpiece, a clamping tool will be needed to fix the workpiece.

[0003] When the existing milling tooling is in use, it is affected by the different outer contours of various workpieces. The clamping contact area between the tooling and the workpiece is small, and the workpiece fixing effect is poor. During the workpiece milling process, the clamping part is prone to loosening, causing the workpiece to move, affecting the workpiece milling accuracy. Utility Model Content
