Abstract

The invention discloses a manufacturing method of a high-strength end mill cutting edge and a double-front-angle end mill. To manufacture a cutting edge of an end mill (1) with a spiral groove, a main front angle (1.1) is firstly manufactured on the cutting edge of the end mill (1), an auxiliary front angle (1.2) is then manufactured on the main front angle (1.1), and the angle (alpha) of the main front angle (1.1) is greater than the angle (beta) of the auxiliary front angle (1.2). The cutting edge disclosed by the invention not only can effectively improve the end mill cutting edge strength and the processing fineness, but also has the advantages of simple processing technology, relatively low manufacturing cost and relatively long service life.

Description

A kind of preparation method of high strength slotting cutter cutting edge and two anterior angle slotting cutter
Technical field
the present invention relates to a kind of preparation method and two anterior angle slotting cutter of high strength slotting cutter cutting edge, belong to the slotting cutter manufacture technology field.
Background technology
In metal cutting process, through the extruding cutting lay generation distortion of cutting edge, smear metal flows to spiral chip flute along rake face and gets rid of ; And the position that is easy to generate damaged and wearing and tearing most generally cutting edge and apart from cutting edge nearer be on the rake face; At present, the shape of its cutting edge is mainly confirmed by anterior angle and relief angle on traditional vertical milling cutter, after the anterior angle of slotting cutter cutting edge and relief angle are confirmed; Under the situation of same material and identical processing technology; The intensity of the cutting edge of this slotting cutter also just confirmed, in order to strengthen the slotting cutter edge strength, the mode that often adopts cutting edge to slotting cutter to carry out Passivation Treatment in the prior art realizes; Though this mode can improve the cutting edge certain intensity; But exist processing technology complicacy, unmanageable shortcoming, and adopt the numerical control machine for inactivating to make, then exist the higher shortcoming of cost again; And the slotting cutter through passivation is adding man-hour, the problem of the piece surface fineness that also easy appearance reduction slotting cutter processes.Therefore, existing slotting cutter manufacturing technology still is not ideal enough.
Summary of the invention
the objective of the invention is; Provide that a kind of processing technology is simple, cost of manufacture is lower and can effectively improve the slotting cutter edge strength and the preparation method of the high strength slotting cutter cutting edge of processing fineness and two anterior angle slotting cutters, to overcome the deficiency of prior art.
technical scheme of the present invention: the preparation method of a kind of high strength slotting cutter cutting edge of the present invention is; When making is provided with the cutting edge of spiral fluted slotting cutter; Earlier on the cutting edge of slotting cutter, produce front (top) rake angle; On front (top) rake angle, produce a front top rake angle then again, make the front top rake angle angle of the front (top) rake angle angle of front (top) rake angle greater than front top rake angle.
A kind of pair of anterior angle slotting cutter of the present invention that make up according to the method described above is: this pair anterior angle slotting cutter comprises and is provided with cutting edge and spiral fluted slotting cutter; And on the cutting edge of slotting cutter, be provided with anterior angle and relief angle; The anterior angle of the cutting edge of its slotting cutter is made up of front (top) rake angle and front top rake angle; Front top rake angle is arranged on the front end of front (top) rake angle; The front (top) rake angle angle of front (top) rake angle is greater than the front top rake angle angle of front top rake angle, and the front top rake angle tail end is 0.1~0.2 millimeter to the distance of slotting cutter cutting edge point of a knife.
The front (top) rake angle angle of above-mentioned front (top) rake angle is 13 °~20 °, and the front top rake angle angle of front top rake angle is 5 °~10 °.
Owing to adopted technique scheme, the present invention has increased a front top rake angle on the anterior angle position of the cutting edge of existing slotting cutter, the anterior angle of former slotting cutter is made up of front (top) rake angle and front top rake angle, and through the design of this pair of anterior angle, the present invention has following characteristics:
1, the cutting lay that can realize the cutting edge extruding is after major first face (front top rake angle knife face) outflow; Smear metal does not have or is seldom pasting second rake face (front (top) rake angle knife face) to flow out; Directly get into helicla flute and get rid of, avoid the wearing and tearing of hard point, bonding abrasion, diffusive wear and the chemical abrasion that produce because of friction apart from the second nearer rake face of cutting edge;
Though 2 major first faces (front top rake angle knife face) are close to smear metal; But second rake face (front (top) rake angle knife face) does not have or seldom directly touches smear metal; Help cooling entering or eliminating; Cooling space more greatly, also comparatively abundant, heat radiation easily, thereby the anti-hard point wearing and tearing, the anti stick that have strengthened major first face (front top rake angle knife face) greatly wear and tear, the ability of anti-diffusive wear and anti-chemical abrasion;
In case 3 cutting edges wearing and tearing or damaged; The front (top) rake angle front top rake angle that will replace works on; Formation cutting edge negative rake that can be very not fast, be difficult to phenomenon such as cutting and produce, can not reduce product quality and production efficiency, thereby effectively raise the service life of cutter;
4, since front top rake angle of the present invention less, width is also less (being the distance of front top rake angle tail end to slotting cutter cutting edge point of a knife); When strengthening cutting edge intensity; Cutting lay distortion in the time of can not influencing incision again; Thereby can not increase cutting resistance, can also guarantee to add simultaneously the surface smoothness quality in man-hour.
Slotting cutter after improve through the present invention like this ; Through evidence; The intensity of its cutting edge will be higher than 2~3 times of conventional end mill, and the piece surface fineness that processes is than highly polished 1~2 the fineness grade of piece surface that under identical machined parameters, processes with the slotting cutter after the change.Therefore, the present invention compared with prior art, the present invention not only has the advantage that can effectively improve slotting cutter edge strength and processing fineness, but also has the advantage that processing technology is simple, cost of manufacture is lower, service life is long.
