Embodiment 1

[0013] Embodiment 1. A milling cutter for machining the inner cavity of a vial, comprising a handle 1, a blade area and a connecting area 3 between the two, the blade area includes three cutting edges 4 and three cutting grooves 5, and the cutting edge 4 The outer contour 41 rotates along the rotation axis 2 and the contour 7 is a drum shape with both ends contracted and the middle bulging. The upper end 71 and the lower end 73 of the drum shape have the same diameter, and the diameter of the middle bulging end 72 is larger than the upper and lower ends. The helix angle A of the blade is 40 degrees, and the handle 1 , the blade area and the connection area 3 are provided with a through axial hole 6 . The three cutting edges form a regular cutting edge, and at the same time, the three cutting edges are beneficial to the processing of the milling cutter itself.

Embodiment 2

[0014] Embodiment 2, the basic structure is the same as that of embodiment 1, the difference is that the helix angle A selected in embodiment 1 is 40 degrees, and the helix angle A selected in this embodiment is 0 degrees, that is, straight edge processing, straight edge tool It is easy to process itself, the cost of manufacturing milling cutters is low, and the surface finish is high.

[0015] According to needs, the helix angle A can also be made to be 80 degrees or slightly larger, which is feasible in theory and practice, but this will increase the manufacturing cost, and the excessively large helix angle A will cause serious distortion.

Abstract

The present invention relates to milling cutter, and is especially one kind of milling cutter for machining the cavity of level gauge. The milling cutter includes one cutter shank, one edge zone and one connecting zone in between. The edge zone includes 2-12 cutting edges and chip pockets in the same quantity, with the cutting edges being drum shaped. The milling cutter has the features of easy chip removal, long service life and capacity of machining surface in special shape.

Description

technical field [0001] The invention relates to a milling cutter, in particular to a milling cutter for processing the inner cavity of a vial. Background technique [0002] At present, the inner cavity of the leveling bubble is usually processed by a turning tool. The turning tool is used to fix the turning tool while the workpiece rotates. The turning tool processing belongs to single-edged processing, and turning belongs to continuous cutting. The life of the turning tool is short and continuous. The cutting of the chip is easy to stay in the inner cavity of the level bubble, which makes it difficult to remove chips in the inner cavity, and does not use special-shaped surface processing at the same time. Contents of the invention [0003] The purpose of the present invention is to solve the defects in the prior art that using a turning tool for machining the inner cavity of the level bubble to turn the workpiece, the chip removal in the inner cavity of the workpiece is d...
