Abstract
The invention belongs to the field of cutters, and particularly relates to an arc-angle end mill which is integrally molded, high in strength, high in rigidity and good in abrasion resistance. The arc-angle end mill comprises a cutter body capable of rotating around the central axis, wherein a cutting part is arranged at the left end of the cutter body, a cutter handle is arranged at the right end, the cutting part comprises concave end surface cutting edges, the included angle formed by every two end surface cutting edges ranges from 168 degrees to 175 degrees, spiral cutting edges are arranged on the surface of the cutting part, a chip removal groove is formed between every two adjacent spiral cutting edges, arc-shaped cutting edges are arranged between the end surface cutting edges and the spiral cutting edges, and carbon nitride coatings are arranged on surfaces of the end surface cutting edges and the spiral cutting edges. The arc-angle end mill which is integrally machined and molded is designed, besides, the end mill adopts the arc-angle design, machined workpieces do not have sharp corners, stress concentration conditions are reduced, and service lives of the workpieces can be prolonged.
Description
Technical field
The invention belongs to cutting tool field, particularly one is one-body molded, and intensity is high, hardness is high and the arc chord angle slotting cutter that wearability is good.
Background technology
The general all cutting portions of existing cutter adopt welding manner to be connected with shank section, and the intensity of the cutter processed like this itself is lower, and under the impact of continuous print cutting force, welding position easily lost efficacy, and cutting-tool's used life is shorter.
Wedge angle is there is between the face cutting edge of existing slotting cutter and side cut sword, workpiece after machining exists wedge angle position, easily area of stress concentration is there is in follow-up heat treatment process, cause workpiece easily to occur losing efficacy in follow-up use procedure, affect the service life of workpiece.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, the present invention devises a kind of one machine-shaping arc chord angle slotting cutter, and the present invention adopts arc chord angle to design in addition, and the workpiece after processing does not exist sharp corner, decrease the generation that stress concentrates situation, be conducive to the service life extending workpiece.
The present invention is achieved through the following technical solutions:
Arc chord angle slotting cutter, it comprises the cutter body rotated around central shaft, left section of described cutter body is provided with cutting portion, right-hand member is provided with handle of a knife, it is characterized in that: described cutting portion comprises the face cutting edge of indent, the angle of face cutting edge is 168 ° ~ 175 °, the surface of cutting portion is provided with spiral cutting sword, chip area is provided with between adjacent spiral cutting sword, be provided with arc edge between described face cutting edge and spiral cutting sword, the surface of described face cutting edge and spiral cutting sword is provided with carbon nitride coatings.
Further, the anterior angle of described face cutting edge is 8 ° ~ 10 °.
Further, described face cutting edge has the first relief angle and the second relief angle, and the first described relief angle is between 10 ° ~ 15 °, and the second relief angle is between 20 ° ~ 25 °.
Further, the helical angle of described spiral cutting sword is 32 °.
In sum, the present invention has beneficial effect:
The present invention devises a kind of one machine-shaping arc chord angle slotting cutter, the present invention adopts arc chord angle to design in addition, there is not sharp corner in the workpiece after processing, decrease the generation that stress concentrates situation, be conducive to the service life extending workpiece, the surface of cutting edge is provided with carbon nitride coatings in addition, effectively can improve intensity and the wearability of cutting edge, extends cutting-tool's used life.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.Wherein:
Figure 1 shows that structural representation of the present invention;
Fig. 2 is the left view of Fig. 1;
In figure, 1 is face cutting edge, and 2 is arc edge, and 3 is spiral cutting sword, and 4 is chip area, and 5 is handle of a knife, and 6 is the first relief angle, and 7 is the second relief angle, and 8 is anterior angle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
Arc chord angle slotting cutter as depicted in figs. 1 and 2, it comprises the cutter body rotated around central shaft, left section of described cutter body is provided with cutting portion, right-hand member is provided with handle of a knife 5, it is characterized in that: described cutting portion comprises the face cutting edge 1 of indent, the angle of face cutting edge 1 is 168 ° ~ 175 °, the surface of cutting portion is provided with spiral cutting sword 3, chip area 4 is provided with between adjacent spiral cutting sword 3, arc edge 2 is provided with between described face cutting edge 1 and spiral cutting sword 3, described face cutting edge 1 and the surface of spiral cutting sword 3 are provided with carbon nitride coatings.
Further, the anterior angle 8 of described face cutting edge is 8 ° ~ 10 °.
Further, described building up by welding cutlery 1
2have the first relief angle 6 and the second relief angle 7, the first described relief angle 6 is between 10 ° ~ 15 °, and the second relief angle 7 is between 20 ° ~ 25 °.
Further, the helical angle of described spiral cutting sword 3 is 32 °.
In sum, the present invention has beneficial effect:
The present invention devises a kind of one machine-shaping arc chord angle slotting cutter, the present invention adopts arc chord angle to design in addition, there is not sharp corner in the workpiece after processing, decrease the generation that stress concentrates situation, be conducive to the service life extending workpiece, the surface of cutting edge is provided with carbon nitride coatings in addition, effectively can improve intensity and the wearability of cutting edge, extends cutting-tool's used life.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
