Abstract
The invention discloses a kind of numerical control boring cutters, are made of cutting tip and knife handle, it is characterised in that: cutting tip includes rake face, minor flank, main flank, main cutting edge, end cutting edge and point of a knife composition；Wherein anterior angle γ takes 0 °；Primary clearance α and front clearance α ' take 6 °；Tool cutting edge angle κ γ takes 100 °；Auxiliary angle κ ' γ takes 2 °.The hard alloy bar of cutter generally.Knife handle is the hard alloy bar not sharpened.Present invention production is simple, low in cost, it is easy to use, it can conveniently be adjusted mended with knife in process, while not only can satisfy the dimensional accuracy and surface roughness requirements of part aperture, the position accuracy demand of aperture is also ensured, to realize that rounding is processed in aperture by numerical control program.
Description
[technical field]
The present invention relates to mechanical manufacturing field more particularly to a kind of numerical control boring cutters.
[background technique]
When processing part as shown in Figure 1, it is multiple to need to process axial hole, radial hole, outer circle and plane etc. by material 3Cr13
All processing is completed using CNC Turning Center equipment clamped one time in position.But to the interior rounding of part left side R0.8mm with
And the interior hole machined of F26mm is relatively difficult, due to using the inner hole of customization reamer finishing F26mm, can not correct the position of inner hole
Tolerance is set, interior rounding can not be also processed；
[summary of the invention]
In view of the problems of the existing technology, easy to use the purpose of the present invention is to provide a kind of simple and reasonable, it can fill
Code insurance demonstrate,proves the numerical control boring cutter of the position accuracy demand of aperture.
The technical solution adopted by the present invention is that: a kind of numerical control boring cutter is made of cutting tip and knife handle, it is characterised in that:
Cutting tip includes rake face, minor flank, main flank, main cutting edge, end cutting edge and point of a knife composition；Wherein anterior angle γ takes
0°；Primary clearance α and front clearance α ' take 6 °；Tool cutting edge angle κ γ takes 100 °；Auxiliary angle κ ' γ takes 2 °.
Further, the hard alloy bar of cutter generally.
Further, knife handle is the hard alloy bar not sharpened.
The beneficial effects of the present invention are: production it is simple, low in cost, it is easy to use, can facilitate in process into
Row adjustment and knife are mended, while not only can satisfy the dimensional accuracy and surface roughness requirements of part aperture, moreover it is possible to guarantee aperture
Position accuracy demand, thus pass through numerical control program realize aperture in rounding processing.
[Detailed description of the invention]
The invention will be further described with reference to the accompanying drawing.

[specific embodiment]
Referring to attached drawing, present invention employs a kind of numerical control boring cutters, are made of cutting tip and knife handle, it is characterised in that: cutting portion
Divide including rake face, minor flank, main flank, main cutting edge, end cutting edge and point of a knife composition；Wherein anterior angle γ takes 0 °；It is main
Relief angle α and front clearance α ' take 6 °；Tool cutting edge angle κ γ takes 100 °；Auxiliary angle κ ' γ takes 2 °.
Further, the hard alloy bar of cutter generally.
Further, knife handle is the hard alloy bar not sharpened.
When processing, the cutter generally hard alloy bar of F25mm.Knife handle is the hard alloy bar for the F25mm not sharpened.
Aperture boring processing, it is desirable that boring cutter intensity is good, radiating condition is good, when tool orthogonal rake γ takes 0 °, as long as by F25mm's
Hard alloy bar just forms rake face to cuing open.
The main function of primary clearance α is the friction reduced between flank and work pieces process position, to improve the table of workpiece
Face quality extends cutting-tool's used life.Increasing primary clearance can make lathe tool cutting edge sharpen, but relief angle, can not only weaken vehicle
The intensity of knife, but also radiating condition can be made to be deteriorated, therefore primary clearance α and front clearance α ' take 6 °；
Tool cutting edge angle κ γ mainly influences the radiating condition of lathe tool, cuts the size of component and the variation of machine direction and influences cutting
The variation of thickness.Because processing blind hole has step, therefore tool cutting edge angle κ γ takes 100 °；
Auxiliary angle κ ' γ mainly reduces the friction of auxiliary-blade Yu workpiece machined surface, influences the suface processing quality and vehicle of workpiece
Knife intensity, therefore, auxiliary angle κ ' γ take 2 °.
The preferred embodiment of the invention, including inventor's best modes known for carrying out the present invention are illustrated herein.
The change of preferred embodiment is obvious after reading the above description for those of ordinary skill in the art.Inventor is uncommon
Those of ordinary skill is hoped rationally to apply such change, and inventor thinks different from clearly stating herein using can also be with
Realize the present invention.Therefore, the present invention includes all modifications and equivalents of purport cited in appended claims, this
It is allowed in applicable law.In addition, any combination of all possible change of above-mentioned element is also encompassed by the present invention,
It is unless otherwise indicated herein or clearly contradicted within a context.
