Abstract
The invention discloses a four-edge flat-end milling cutter. The four-edge flat-end milling cutter comprises a tool shank, wherein a tool bit is formed on the tool shank, spiral main cutting edges and auxiliary cutting edges are formed on the tool bit, a cutting groove is formed between two adjacent main cutting edges, a horizontal edge front end surface is formed at the top end of the tool bit, the spirals of the main cutting edges and the auxiliary cutting edges are in the right-hand direction, and the main cutting edges are located on the right sides of the auxiliary cutting edges; a front cutting angle and a rear cutting angle are formed on the front end surface of each edge, and the front cutting angle is larger than the rear cutting angle; a V-shaped groove tail is formed in the rear of a cutting groove; and an included angle between the auxiliary cutting edge at the tail end of the cutting groove and the central axis of the tool shank is 15 degrees. The four-edge flat-end milling cutter adopts the right-hand rotating and right-cutting type spiral cutting teeth, so that chips are discharged from the front end of the milling cutter during processing of a silica gel material, a god chip removal effect is achieved, and the front cutting angle is increased, accordingly, the cutting amount is reduced, the silica gel material is more convenient to cut, and the quality of a milled finished product is guaranteed.
Description
Technical field:
The present invention relates to the technical field of milling cutter, more particularly relate to a kind of four sword flat-end cutters.
Background technology:
Milling cutter is a kind of important cutter using in modern industry machined, the profile of tooth of present milling cutter is generally given straight tooth-shaped and screw serrated form, screw serrated form has better chip removal effect than the milling cutter of straight tooth-shaped, and existing screw serrated form milling cutter is all generally to adopt dextrorotation left cut type or left-handed right cut type, thereby the chip removal mode of its milling cutter is all generally interior discharges of cutting slot of edge of milling cutter rear end.And when the softer material of some quality of processing as soft rubber, silica gel etc., when the side of these materials of milling, chip removal is difficult for discharging from cutting slot, thereby affects the crudy of product.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and four sword flat-end cutters are provided, and it adopts the spiral cutter teeth of dextrorotation right cut formula, and has increased cutting anterior angle, is convenient to the cutting of silica gel material, and has good chip removal effect.
For achieving the above object, a kind of four sword flat-end cutters of the present invention comprise handle of a knife, on handle of a knife, form cutter head, on cutter head, form spiral main cutting edge and front cutting edge, between two adjacent main cutting edges, form cutting slot, the top of cutter head forms the blade front end face of level, and described main cutting edge and the rotary orientation of front cutting edge are dextrorotation, and cutting edge is positioned at the right side of front cutting edge; Moulding smear metal anterior angle and smear metal relief angle on blade front end face, described smear metal anterior angle is greater than smear metal relief angle; Described cutting slot rear side forms the groove tail of V-type, and front cutting edge and the angle between handle of a knife central axis of cutting slot groove tail end are 15 °.
As technique scheme preferably, described milling cutter adopts the helical tooth cutter of four swords.
Beneficial effect of the present invention is: it adopts the spiral cutter teeth of dextrorotation right cut formula, thereby during machine silicon glue material, smear metal is discharged from milling cutter front end, there is good chip removal effect, and increased cutting anterior angle, reduced scrap rate, the cutting of silica gel material of being more convenient for, thus the quality of milling finished product guaranteed.
Accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is structural representation of the present invention;
Fig. 2 is that enlarged drawing is looked on the right side of cutter head 2 of the present invention.
Symbol description in figure:
1, handle of a knife; 2, cutter head; 3, main cutting edge; 4, front cutting edge; 5, cutting slot; 6, blade front end face; α, smear metal anterior angle; β, angle; γ, smear metal relief angle.
The specific embodiment:
See shown in Fig. 1 and Fig. 2: four sword flat-end cutters of the present invention comprise handle of a knife 1, on handle of a knife 1, form cutter head 2, on cutter head 2, form spiral main cutting edge 3 and front cutting edge 4, between two adjacent main cutting edges 3, form cutting slot 5, the top of cutter head 2 forms the blade front end face 6 of level, described main cutting edge 3 and the rotary orientation of front cutting edge 4 are dextrorotation, and cutting edge 3 is positioned at the right side of front cutting edge 4; Moulding smear metal anterior angle α and smear metal relief angle γ on blade front end face 6, the smear metal relief angle γ that described smear metal anterior angle α is greater than; Described cutting slot 5 rear sides form the groove tail of V-type, and the angle β between the front cutting edge 4 of cutting slot 5 groove tail ends and handle of a knife 1 central axis is 15.
Milling cutter adopts the helical tooth cutter of four swords.
Operation principle: the present invention is processed into dextroform by the helical tooth of milling cutter, and increased cutting anterior angle, and cutting the mode that adopts right cut, thereby in processing in process the smear metal under its cutting without discharging the cutting slot between cutting edge, directly from the front end of milling cutter, discharge, thereby can not cause smear metal from cutting slot, not discharge, make it have and good chip removal effect.Increase cutting anterior angle simultaneously, reduced scrap rate, the cutting of the silica gel material of being more convenient for, thus guaranteed the quality of milling finished product.
Above content is only preferred embodiment of the present invention, for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, and this description should not be construed as limitation of the present invention.
