Description
Technical field
The utility model relates to printed wiring board manufacturing fields, more particularly, to a kind of not isometrical counter bore processing cutter.
Background technique
The effective carrier of wiring board effect electronic component is called always the aircraft carrier of electronic component, is that hyundai electronics are set
Standby, product key core component is that fast-developing powerful support is able to modern science and technology technical level, to the peace of product
Entirely, stable, efficient, reliability has huge effect and influences, especially in Aeronautics and Astronautics, military project, automobile, shipbuilding, power generation
Field require just more stringent, therefore, people guarantee wiring board efficient, high speed, high-quality, low by various technological means
Cost is produced into as important subject and activity description.
Counterbore is as, using extremely popularizing, the processing method about counterbore is also a variety of more in a kind of functional hole assist side
Sample.In particular with the continuous development of wiring board manufacturing technology, various counterbore layers are not studied carefully out, and difficulty of processing is increasingly
Greatly, use etc. the problem of bringing more and more to product quality process control, tool management, lathe, in process
Often there are the various problems such as breaking, deviation, dislocation, hole shape exception, dimension overproof, rough surface, seriously affect product quality,
And cause the increase of manufacturing cost.
The usually used cutter of industry has the disadvantages that first, and geometry, geometric angle are extremely complex, grind
Hair, manufacturing cost are very high；Second, typically single classification hole machined, it is necessary to first process through-hole, reprocess counterbore, work
Skill is complicated；Third, since process control is extremely difficult to design requirement, actual processing comes out cutter due to retained part and cutting portion
The radius run-out degree that the reasons such as Concentricity tolerance, the tool in cutting sword asymmetry divided generate cutter when rotating increases
Greatly, so being just very easy to covibration occur when processing higher phenolic aldehyde, glass class hardness, workpiece of the larger material of brittleness,
It is light then hole surface roughness is caused to increase, it is heavy then after directly resulting in hole shape exception, breaking, lathe damage, product abandonment etc. seriously
Fruit；4th, purchase cost is higher.
Summary of the invention
The purpose of the utility model is to overcome drawbacks described above of the existing technology, provide a kind of not isometrical counterbore processing
Cutter can directly process not isometrical counterbore, not only improve counterbore processing efficiency, but also improve counterbore processing quality.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of not isometrical counter bore processing cutter, which is characterized in that including cutting tip, stop collar and bit sub；
Cutting tip is spade, the point of a knife, the shaped segment being connected with point of a knife including end and the mistake being connected with stop collar
Cross chamfering section；Shaped segment two sides are cutting edge；
Shaped segment is not wide.
Further, the shaped segment is the not wide shaped segment changed linearly, or is differing in nonlinear change
Wide shaped segment.
Further, the cutting edge of the not wide shaped segment in nonlinear change is by vertical line, oblique line and camber line
Two or three of combination constitute.
It can be seen from the above technical proposal that the not wide cutter that the utility model is shaped by using time processing, it can
With rapid processing deformity counterbore, through-hole and at least two can be carried out disposably in high precision, efficiently with the cone shaped countersink of upper angle
Rate processing, process operation is simple, and counterbore quality is guaranteed.
Detailed description of the invention
Fig. 1 is the main view of the cutter of one specific embodiment of the utility model；
Fig. 2 is the side view of cutter shown in FIG. 1；
Fig. 3 is the main view of the cutter of the utility model another specific embodiment；
Fig. 4 is the main view of the cutter of the utility model another specific embodiment；
Fig. 5 is the main view of the cutter of the utility model another specific embodiment.
Specific embodiment
With reference to the accompanying drawing, specific embodiment of the present utility model is described in further detail.
It should be noted that in following specific embodiments, when the embodiments of the present invention is described in detail, in order to
The structure of the utility model is clearly showed that in order to illustrate, spy does not draw to the structure in attached drawing according to general proportion, goes forward side by side
Gone partial enlargement, deformation and simplify processing, therefore, should be avoided in this, as the restriction to the utility model to understand.
In following specific embodiment of the present utility model, Fig. 1 and Fig. 2 are please referred to.As shown, the utility model is public
A kind of not isometrical counter bore processing cutter, including cutting tip 04, stop collar 02 and bit sub 01 are opened.Bit sub 01 is for installing
In on the drilling tool collet of existing numerically-controlled machine tool.
Cutting tip 04 is spade, point of a knife 041 including end, the shaped segment being connected with point of a knife and is connected with stop collar
Transition chamfering section 044；Shaped segment two sides are cutting edge；Shaped segment is not wide.In the present embodiment, cutting edge is by vertical line
042 and oblique line 043 constitute, the counterbore shape of the tool sharpening of formation is divided into two parts, a part be it is cylindrical, a part is round
Taper.
Shaped segment can be the not wide shaped segment changed linearly, referring to Fig. 3, or not in nonlinear change
Wide shaped segment, referring to Fig. 1~2, Fig. 4~5.
In nonlinear change not wide shaped segment cutting edge by two or three in vertical line, oblique line and camber line
Combination is constituted, referring to 1~2, Fig. 4~5.
Above-mentioned cutter is made of hard alloy.
It can be seen from the above technical proposal that the not wide cutter that the utility model is shaped by using time processing, it can
With rapid processing deformity counterbore, through-hole and at least two can be carried out disposably in high precision, efficiently with the cone shaped countersink of upper angle
Rate processing, process operation is simple, and counterbore quality is guaranteed.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its inventive concept is subject to equivalent substitution or change, should all cover the protection scope of the utility model it
It is interior.
