Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: a Z-axis double feed cutting milling insert comprising: the tool comprises a front end inner groove profile blade 1, a rear end inner groove profile blade 2 and a tool handle 3, wherein one end of the tool handle 3 is provided with the front end inner groove profile blade 1 and the rear end inner groove profile blade 2, the front end inner groove profile blade 1 and the rear end inner groove profile blade 2 are of a double-turning and double-groove structure, one side of the front end inner groove profile blade 1 is provided with a right-turning straight groove cutting edge 101, a tool face, opposite to the transition surface of a workpiece, of the front end inner groove profile blade 1 is provided with a front end inner groove profile first relief angle 102, the tool face, opposite to the transition surface of an arc workpiece, of the front end inner groove profile blade 1 is provided with a front end blade first relief angle 103 and a front end blade second relief angle 104, the front end inner groove profile blade 1 is processed in a Z-axis downward insertion mode, the right-turning straight groove cutting edge 101 is used in a limited space, the rigidity of the tool is ensured, the cutting edge in the processing is discharged upwards, one side of the rear end inner groove profile turning edge 2 is provided with a left-turning edge 201, rear end inner groove profile sword 2 rear end face profile and the relative knife face in work piece transition surface are formed with rear end indent profile first relief angle 202, rear end inner groove profile sword 2 is formed with rear end sword first relief angle 203 and rear end sword second relief angle 204 at the excircle with the relative knife face in circular arc work piece transition surface, rear end inner groove profile sword 2 is with the processing of inserting on the Z axle, wherein, levogyration is to letting the cutting in the processing downwards discharge when spiral blade 201 is used for guaranteeing rear end profile precision, front end inner groove profile sword 1 and rear end inner groove profile sword 2 correspond between tool bit position and the handle of a knife 3 for the circular arc transition.
