Abstract

The invention belongs to the field of cutting tools, and concretely relates to a ball-nose end milling cutter. The ball-nose end milling cutter comprises a milling cutter handle, a milling cutter body and a ball-nose cutter tip, the milling cutter body is provided with a milling cutter edge and a milling cutter slot, the ball-nose cutter tip is provided with a tip centering part, the tip centering part is conical in shape, and the height H of the tip centering part is 1mm. The ball-nose end milling cutter has the advantages of accurate positioning, production quality improvement and production efficiency increase by arranging the tip centering part.

Description

A kind of ball end mill
Technical field
The invention belongs to cutting tool field, specifically a kind of ball end mill.
Background technology
Blade shapes has a variety of, and on plain-milling machine and CNC milling machine working groove and outline of straight line, milling boring machining center, processing cavity, core, curved profile, profile are used.
During common rose cutter processing high-hardness steel sword, because the large mouth of cutting force easy tipping during rose cutter processing dead-hard steel, the life-span is low, in order to solve such problem, traditional way is that ball tooth rake face is made negative rake sword, and do like this and cutting force can be made obviously to increase, cutting temperature obviously raises.
Simultaneously common rose cutter, owing to being felt relieved by spherical surface and cutting face, is caused cutting and easily wanders off, cannot accurately feel relieved.
Summary of the invention
The present invention is directed to shortcoming in above-mentioned technology, provide the life-span long, a kind of ball end mill that can accurately feel relieved.
Realize technical scheme of the present invention as follows:
A kind of ball end mill, it comprises milling cutter shank, milling cutter body and bulb point of a knife, and described milling cutter is provided with milling cutter sword and milling cutter groove with it, and bulb point of a knife is provided with top centring elements, and this top centring elements is conical, and height H is 1mm.
Be provided with in described milling cutter groove and raised item is set along milling cutter groove spiral.
Described milling cutter shank is that Split type milling cutter handle is welded, and weld seam is ridge shape weld seam.
Advantage of the present invention can accurately be located by top centring elements, improves the quality of production and efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
As shown in Figure 1, a kind of ball end mill, it comprises milling cutter shank 1, milling cutter body 2 and bulb point of a knife 3, described milling cutter body 2 is provided with milling cutter sword 2a and milling cutter groove 2b, bulb point of a knife 3 is provided with top centring elements 3a, and this top centring elements 3a is conical, and height H is 1mm.
Be provided with in described milling cutter groove 3b and raised item 2c is set along milling cutter groove spiral.
Described milling cutter shank is that Split type milling cutter handle is welded, and weld seam 4 is ridge shape weld seam.
