Portion has arc groove, and the facade of the cutter hub at described arc groove place is provided with recessed cylinder blade, and recessed cylinder blade is positioned at circular arc
The both sides of groove；The plane of the cutter hub at described arc groove place is provided with projection face blade, and projection face blade is positioned at arc groove
Both sides.
Say further, the negative rake of heretofore described arc groove be anterior angle be-55 °～-60 °.
Saying further, the ratio of the width b of heretofore described arc groove and the width a of cutter hub is 1:2.
A kind of processing method processing above-mentioned Novel cutting breaking, this processing method comprises the following steps:
1), according to the width a of the cutter hub of flat type, the cylinder radius size of recessed cylinder blade is set；Its concave cylinder cutter
The cylinder radius size of sword (5) is 1/4th of cutter hub width a；
2) arc groove is set up in the centre position at the straight line sword of cutter hub, and the negative rake of arc groove is-62 °, and circular arc
The ratio of the width b of groove and cutter hub width a is 1:2；
3) according to step 1) in the cylinder radius size of recessed cylinder blade that arranges process recessed cylinder blade, recessed cylinder cutter
Sword is distributed in the both sides of arc groove；
4), according to step 1) in arrange cylinder radius size process projection face blade, projection at the upper surface of cutter hub
Curved indentations is formed between the blade of face.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention can realize cutting operation by the straight line sword arranged with curve sword, and can be by reasonably knot
Structure design realizes the smooth and easy discharge of chip, alleviates cutter and draws the phenomenon that the section partially brought is the most smooth, improves workpiece two
The surface quality of side.
2, the amputation knife after processing method of the present invention and processing are capable of the standardized production of blade, it is simple to batch
Amount processing and production, and the quality of production is stable.
3, the present invention cut stable, production efficiency 3～4 times can be improved, improve cutting off tool in use 2～3
Service life again,
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1, cutter hub；2, curved indentations；3, projection face blade；4, arc groove；5, recessed cylinder blade；6, facade is recessed
Groove.
Detailed description of the invention
Below in conjunction with the accompanying drawings and technical scheme described herein is described further by embodiment.
Embodiment 1: a kind of Novel cutting breaking, including cutter hub 1, described cutter hub 1 is flat type cutter hub, the straight line sword of cutter hub 1
Middle part has arc groove 4, and the facade of the cutter hub 1 at described arc groove 4 place is provided with recessed cylinder blade 5, recessed cylinder blade 5
Both sides in arc groove 4；The plane of the cutter hub 1 at described arc groove 4 place is provided with projection face blade 3, projection face blade 3
Both sides in arc groove 4.
Embodiment 2: a kind of Novel cutting breaking, the anterior angle of wherein said arc groove 4 is-55 °～-60 °.Described circular arc is recessed
The ratio of the width b of the groove 4 and width a of cutter hub 1 is 1:2.The structure of remainder is same as in Example 1.
The processing method of Novel cutting breaking in a kind of process embodiment 1 or 2, this processing method comprises the following steps:
1) according to the width a of the cutter hub (1) of flat type, the cylinder radius size of recessed cylinder blade 5 is set；Its concave cylinder
The cylinder radius size of blade 5 is 1/4th of cutter hub 1 width a；
2) arc groove 4 is set up in the centre position at the straight line sword of cutter hub 1, and the anterior angle of arc groove 4 is-55 °～-60 °,
And the ratio of the width b of arc groove 4 and cutter hub 1 width a is 1:2；
3) according to step 1) in the cylinder radius size of recessed cylinder blade 5 that arranges process recessed cylinder blade 5, recessed cylinder
Blade 5 is distributed in the both sides of arc groove 4；
4) according to step 1) in arrange cylinder radius size process projection face blade 3, projection at the upper surface of cutter hub 1
Curved indentations 2 is formed between face blade 3.
In view of technique scheme, cutter hub 1 is flat type cutter hub, has arc groove in the middle part of the facade trimming of cutter hub 1
4, linear cutting edge primarily serves shear action, and curve sword is Dampening regions, and this Dampening regions can effectively prevent vibration,
Reduce the problem that amputation knife the most easily produce chatter.The main cutting edge of flat type cutter hub is formed by arc groove 4
Article three, main cutting edge, during owing to coming into contact with workpiece, main cutting edge length in the present invention reduces, so when contacting workpiece by
Existence in above-mentioned Dampening regions makes to process and steadily can not form vibration.
The effect of arc groove 4 is in addition to as Dampening regions, additionally it is possible to prevent cutting off tool from drawing partially.Arc groove 4 with
When active force between adjacent straight line sword can offset Tool in Cutting, the machined surface counteracting force to cutter, offsets or weakens
This axial force such that it is able to play and prevent cutter from drawing inclined effect.
The horizontal surface of the cutter hub 1 of arc groove 4 place flat type is provided with projection face blade 3, projection face blade 3
Quantity is 2 and is distributed in the both sides of arc groove 4.Acting as of projection face blade 3: 1 increases cutter both sides point of a knife intensity；2
Carry out chip removal to coordinate to make chip along the smooth and easy discharge of rake face.
It is provided with recessed cylinder blade 5 on the vertical surface of the cutter hub 1 of the flat type at arc groove 4 place, carries out chip removal coordination
Make chip along the parallel discharge of negative rake.
