Abstract
The invention discloses a method for enhancing chip removal capability of an end mill, characterized in that: when producing an end mill, a removal-increasing groove surface is added between a chip groove surface behind a back angle surface of each tooth and a spiral groove of the end mill, so that the chips generated in a cutting process of the end mill arrive in the spiral groove passing through the chip groove surface and the removal-increasing groove surface and then are removed from the end mill. By adding a removal-increasing groove surface between a chip groove surface behind a back angle surface of each tooth and a spiral groove of the end mill, the removal-increasing groove surface and one surface of the existing spiral groove make up a removal-increasing groove, the removal-increasing groove has the transition function for gradually changing the direction of chip removal and increases the circulation space of the chips to let the chips be removed from the end mill through the spiral groove after gradually changing the direction. The invention has the advantages of fluent chip removal, high processing smoothness, high precision, simple structure, and easy production.
Description
Technical field
the present invention relates to a kind of method that strengthens slotting cutter chip removal ability, belong to the end mill tool manufacture technology field.
Background technology
are present; After generally all being to be employed in the rear corner surface of each cutter tooth of slotting cutter on traditional vertical milling cutter, produce the chip removal groove face that communicates with the helicla flute of slotting cutter, the smear metal that when slotting cutter is carrying out cut, is being produced like this is discharged to outside the slotting cutter after directly being discharged to helicla flute through the chip removal groove face again.This chip removal structure of existing slotting cutter; Because the angle between its chip removal groove face and the spiral groove face is smaller; When the workpiece chips that machines away gets into helicla flute through chip area the bigger change of angle can take place when being cut; Be easy to produce the slack problem of smear metal obstruction or chip removal like this and take place, particularly outstanding when high-speed cutting, thus cause processed workpiece surface finish or precise decreasing.Therefore, existing slotting cutter chip removal performance still is not ideal enough.
Summary of the invention
the objective of the invention is, and the method that a kind of chip removal is smooth and simple in structure, make easy enhancing slotting cutter chip removal ability are provided, to overcome the deficiency of prior art.
technical scheme of the present invention is: comprise by existing mode and make slotting cutter; When making slotting cutter; All produce one between the chip removal groove face after being located at the rear corner surface of each cutter tooth and the helicla flute of slotting cutter and increase the emissions groove face, the smear metal that slotting cutter is produced when carrying out cut is discharged outside the slotting cutter after the emissions groove face is discharged to helicla flute through increasing behind the process chip removal groove face rapidly again.
above-mentioned angle that increases emissions groove face and spiral fluted spiral groove face is 82 °～88 ° angles.
are owing to adopted technique scheme; The present invention produces one and increases the emissions groove face between the helicla flute of chip removal groove face after the rear corner surface of each cutter tooth of existing slotting cutter and slotting cutter; This increases the emissions groove face and one of face composition of original spiral fluted increases emissions groove; And the angle that increases emissions groove face and spiral groove face greater than the angle between existing slotting cutter smear metal groove face and the spiral groove face (like Fig. 3 and shown in Figure 6; Fig. 3 is a structural representation of the present invention, and Fig. 6 is the structural representation that does not increase the existing slotting cutter of emissions groove face), therefore increase emissions groove and can play the transitional function that direction is discharged in conversion smear metal gradually; And increased the space that smear metal is circulated, smear metal is discharged to outside the slotting cutter through helicla flute after the direction that gradually changes again.So the present invention compared with prior art, and the present invention not only has advantage of higher of chip removal smoothness, processing fineness and precision, but also have simple in structure, the easy advantage of making.

The specific embodiment
are done further detailed description below in conjunction with accompanying drawing and embodiment to the present invention.
embodiments of the invention: when making traditional slotting cutter; Can adopt the method for enhancing slotting cutter chip removal ability of the present invention to make slotting cutter; Earlier produce slotting cutter 1 by existing mode, the specification of slotting cutter 1 can be confirmed by existing mode as required, when making slotting cutter 1 by existing mode; Slotting cutter 1 is placed on the existing milling cutter grinding machine; Grinding is produced one and is increased emissions groove face 5 again between the helicla flute 4 of chip removal groove face 3 after the rear corner surface 2 of the cutter tooth that is located at each slotting cutter 1 and slotting cutter 1, when grinding increases emissions groove face 5, can grind away the sub-fraction of a spiral groove face of former slotting cutter 1 helicla flute 4; In grinding, will increase emissions groove face 5 and helicla flute 4 be not controlled between 82 °～88 ° angles by the angle of another spiral groove face 4.1 of grinding and can.
Claims (2)
1. method that strengthens slotting cutter chip removal ability; Comprise by existing mode and make slotting cutter (1); It is characterized in that: when making slotting cutter (1); All produce one between the chip removal groove face (3) after being located at the rear corner surface of each cutter tooth (2) and the helicla flute (4) of slotting cutter (1) and increase emissions groove face (5), discharge again outside the slotting cutter (1) after the transition that increases emissions groove face (5), arrive helicla flute (4) again after can making smear metal that slotting cutter (1) produced through chip removal groove face (3) like this when carrying out cut after.
2. the method for enhancing slotting cutter chip removal ability according to claim 1 is characterized in that: the angle (α) that increases the spiral groove face (4.1) of emissions groove face (5) and helicla flute (4) is 82 °～88 ° angles.
