Detailed Description

In order that the utility model may be more fully understood, a more particular description of the utility model will be rendered by reference to the appended drawings, in which several embodiments of the utility model are illustrated, but which may be embodied in different forms and are not limited to the embodiments described herein, which are, on the contrary, provided to provide a more thorough and complete disclosure of the utility model.

The present utility model will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1-3, the milling cutter comprises a milling cutter handle 1, a connector 11 is fixedly arranged at the upper end of the milling cutter handle 1, the structural design is simple, a cutter head 2 is conveniently connected with a milling machine, a cutter blade 21 is arranged on the milling cutter head 2, a bottom blade 3 is fixedly arranged at the lower end of the cutter blade 21, the side spiral angle of the cutter blade 21 is 38 degrees, a cutter blade group 34 is fixedly arranged at the lower end of the bottom blade 3, and the structural design is simple, so that the contact area between the cutter and a workpiece is larger when the workpiece is machined, the machined surface of the workpiece is smoother to a certain extent, the time cost for polishing the surface of the workpiece again is reduced, the machining working efficiency is improved, the pressure of the cutter head can be reduced while the contact area is increased, the better supporting performance is improved, and the service life of the cutter is prolonged.
