Description
Technical field
The present invention relates to cutting tool, particularly relate to one and both can be suitably used for radial cut groove, cut-out, can be suitably used for again axially
The blade of turning.
Background technology
In the cutting process of material, the curling of chip and to discharge the continuous cutting for workpiece and process be quite to weigh
, elongated and uncontrollable chip easily causes the interruption of processing, affects workpiece surface quality and even causes the report of workpiece
Useless, operator's lathe of having to stop, to clear up the chip of winding or to change workpiece, greatly reduces production efficiency, also increases
Add processing cost.Meanwhile, the oscillation phenomenon in the course of processing is also disadvantageous, generally for reducing or avoiding vibration, needs
Reduce cutting speed or other cutting parameters of processing, be also unfavorable for the raising of production efficiency.The grooving course of processing at material
In, grooving cutter has generally required the different process requirements such as radially grooving, cut-out and axial turning, and therefore blade is radially
Grooving, cut-out and axial turning need to be designed with rational cutting edge and chip breaking structure.
Patent documentation CN2871070Y discloses a kind of for radial direction grooving and axial Toolbit for cutting, although substantially can be
Radially grooving, cut-out and axially realize shaping and the fracture of chip in turning, but its chip breaking grooved simple in construction, function singleness,
Distance cutting edge farther out, is difficult to effective control of chip, and the radial cut of blade in polish and semifinishing scope
Cutting cutting edge is shaped form structure, although reducing the radial cutting force of blade, improve cutting vibration, beneficially machined parameters is relatively
Big roughing, but in the range of the less semifinishing of machined parameters and polish, blade cut power is less, and this shaped form is tied
Structure is limited for the improvement of cutting force, can reduce the surface smoothness of workpiece on the contrary, is not carried out both improvement truly
Cutting vibration ensures again surface of the work crudy.
Summary of the invention
It is an object of the invention to solve the deficiencies in the prior art, it is provided that a kind of for radially grooving, cut-out and
The axially Multifunctional blade of turning, it has possessed good chip control and chip breaking effect, and the range of work is wide, can reduce cutting
Power, the vibration making cutting brisk and reducing in processing, workpiece processing quality is high, and service life is long.
In order to achieve the above object, the technical scheme is that
A kind of radial direction grooving, cut-out and the Multifunctional blade of axially turning, including cutting head and along cutting head longitudinal direction
The clamping shank extended, described cutting head includes knife face after a upper surface, two side surfaces and a master, cutter after described master
Intersect composition main cutting edge with upper surface in face, and two side surfaces intersect composition side cutting edge, described main cutting respectively with upper surface
Sword two ends are connected with side cutting edge by fillet cutting edge respectively, and described upper surface middle part is set to groove, described main cutting edge
Being connected by the first inclined plane with between described groove front end, described side cutting edge is respectively by the second inclined plane and described groove
Both sides connect, and described clamping shank and described groove rear end are connected by cone boss and the tip of cone boss is towards described master
Cutting edge is arranged, the intersection of described first inclined plane and described second inclined plane is respectively provided with radially grooving, cut-out
Oval chip breaking boss, described second inclined plane is respectively provided with the circular arc chip breaking boss of axial turning, described circular arc
In the middle part of shape chip breaking boss, front end close with described side cutting edge connects with described oval chip breaking boss and rear end and described taper
Boss connects, and described main cutting edge is α with the angle of plane P, and described side cutting edge is β with the angle of plane P, described plane P
And longitudinal extension along blade vertical with the longitudinal center plane of blade.
Further improvement as technique scheme: described α is in the range of 7 °-15 °, and described β is in the range of 7 °-15 °.
Further preferred as technique scheme, side cutting edge described in the aspect ratio of described circular arc chip breaking boss is high
0.03-0.1mm；Main cutting edge height 0.03-0.12mm described in the aspect ratio of described circular arc chip breaking boss.
Compared with prior art, it is an advantage of the current invention that: radial direction grooving disclosed by the invention, cut-out and axial turning
Multifunctional blade, its main cutting edge is α with the angle of plane P, and side cutting edge is β with the angle of plane P, before i.e. blade just has
Angle, blade is sharp, and the plastic deformation of cutting lay and frictional resistance reduce, and reduce cutting force, decrease shaking in the course of processing
Dynamic, the operating mode that process system rigidity is poor or machine power is not enough can be used for；Axially during turning, chip is convex with circular arc chip breaking
Platform crimps and fragments into the control of easy-to-handle Chip Shape, beneficially chip and fracture after clashing into, and circular arc chip breaking is convex
Platform runs through the length of whole side cutting edge, can meet the chip breaking demand of different machining parameters in the blade range of work, processes model
Enclose wide；Oval chip breaking boss can make chip lift and curl into V-arrangement, favorably in radial direction grooving, cutting-off process
Fractureing and discharging in chip, decreases the contact area of chip and rake face, thus slow down the abrasion of rake face, extend
The service life of blade.
