Abstract

The utility model relates to a ball-headed milling cutter, which comprises a cutter head and a cutter shank which are formed integrally. The cutter head is provided with two spherical cutting edges which are spaced by 180 degrees, each spherical cutting edge is provided with a rake face and a spherical flank, the rake face is coincident with the axial section of the cutter shank, the spherical radius of the flank is 20mm, the cutting head is further provided with two V-shaped filing removal grooves which are arranged corresponding to the cutting edges, each V-shaped groove is formed by intersecting a cambered surface and the corresponding rake face of the corresponding cutting edge, each cambered surface is milled out on the cutter head and is perpendicular to the corresponding rake face, the diameter of the cutter head is larger than that of the cutter shank, and a shaft shoulder is arranged between the cutter head and the cutter shank. Since the cutter head of the milling cutter is ball-shaped, a circular arc-shaped groove machined by the ball-headed milling cutter can be formed once, and machining efficiency is improved greatly.

Description

A kind of rose cutter

Technical field

The utility model relates to a kind of milling cutter, particularly a kind of rose cutter.

Background technology

In the prior art, copying is generally adopted plain cutter, the processing time consuming effort is cut precision and can not get guaranteeing.

The utility model content

The purpose of the utility model is, overcomes the deficiency of prior art, and a kind of high efficiency rose cutter is provided.

For realizing above-mentioned purpose, the utility model has adopted following technical scheme:

A kind of rose cutter; Comprise integrated cutter head and handle of a knife, said cutter head has the sphere cutting edge of the 180 ° of settings in two intervals, said sphere cutting edge have the rake face that overlaps with the handle of a knife axial section; One is the back knife face of sphere; The spherical radius of said back knife face is 20mm, also has two chip removal V-shaped grooves that corresponding cutting edge is provided with on the cutter head, and said V-shaped groove is by the rake face of cutting edge and crossing the forming of the cambered surface perpendicular to rake face that on cutter head, mills out; The diameter of cutter head is greater than handle of a knife, is provided with the shaft shoulder between itself and handle of a knife.

The beneficial effect of the utility model is that milling cutter tip is spherical, and when the processing arc groove, but one-shot forming has improved working (machining) efficiency greatly.

Description of drawings

Fig. 1 is the structure chart of the utility model rose cutter.

The specific embodiment

As shown in Figure 1:

A kind of rose cutter of present embodiment; Comprise integrated cutter head 1 and handle of a knife 2, said cutter head 1 has had two intervals sphere cutting edge 3 of 180 ° of settings, said sphere cutting edge 3 have the rake face 4 that overlaps with the handle of a knife axial section; One is the back knife face 5 of sphere; The spherical radius of said back knife face 5 is 20mm, also has two chip removal V-shaped grooves that corresponding cutting edge is provided with on the cutter head, and said V-shaped groove is by the rake face 4 of cutting edge and cambered surface 6 crossing the forming perpendicular to rake face that on cutter head, mill out; The diameter of cutter head 1 is greater than handle of a knife 2, and itself and 2 on handle of a knife are provided with the shaft shoulder 7.
