Abstract
End milling cutter, including tool bit, shoulder and handle of a knife, shoulder one end is connected with the handle of a knife, the shoulder other end is connected with tool bit portion, the tool bit includes side tool sword and counteredge, the side tool sword sets up in the tool bit lateral part, the counteredge sets up at the tool bit tip, the side tool sword is equipped with three and be the heliciform, be equipped with the chip groove between the side tool sword, be equipped with first relief angle, second relief angle and third relief angle on the counteredge. The utility model discloses be fit for the big volume processing of cutting, through be equipped with first relief angle, second relief angle and third relief angle on the counteredge, increased and held the bits space, make iron fillings in time discharge, reduced the cutting resistance and the wearing and tearing volume of cutter to prolonged the life of cutter owing to hold the big iron fillings in bits space and be difficult to block up near cutter and finished surface, can be directly when making the cutter cutting and the work piece contact, thereby improved the machining precision of work piece.
Description
Technical field
The utility model is related to a kind of cutter, particularly to slotting cutter.
Background technology
Milling cutter, be for Milling Process, the rotary cutter with one or more cutters tooth.During work each cutter tooth successively between
Cut the surplus of workpiece with having a rest.Milling cutter is mainly used in processing plane, step, groove, profiled surface and cut-out workpiece on milling machine
Deng.Slotting cutter is for processing groove and step surface etc., and cutter tooth, on circumference and end face, can not feed during work vertically.When
When end tooth by center is had on slotting cutter, can axial feed.Common slotting cutter counteredge is provided with two relief angles, common
Slotting cutter is not suitable for big cutting output processing, and because chip space is little, iron filings can not be discharged in time, and can increase Tool in Cutting resistance
Power, makes cutter easily wear and tear, and reduces cutting-tool's used life, and the iron filings discharged in time easily get lodged in cutter and add
The vicinity in work face, during tool sharpening, iron filings can hinder the contact that cutter is with machined surface, thus reducing the machining accuracy of workpiece.
Utility model content
The purpose of this utility model be provide a kind of when big cutting output is processed not only can with tool life, and
And the slotting cutter of Workpiece Machining Accuracy can also be improved.
To achieve these goals, the technical scheme that the utility model is adopted is as follows:
Slotting cutter, including cutter head, shoulder and handle of a knife, described shoulder one end is connected with handle of a knife, the described shoulder other end with
Cutter head is connected, and described cutter head includes side tool sword and counteredge, and described side tool sword is arranged at cutter head sidepiece, described counteredge setting
In cutter head end, described side tool sword is provided with three and in the shape of a spiral, is provided with chip area, on described counteredge between described side tool sword
It is provided with the first relief angle, the second relief angle and the 3rd relief angle.
Described first relief angle is 25 °.
Described second relief angle is 67 °.
Described 3rd relief angle is 95 °.
The beneficial effects of the utility model are: the utility model is suitable for the amount of cutting processing greatly, by being provided with the on counteredge
One relief angle, the second relief angle and the 3rd relief angle, increase chip space, so that iron filings is discharged in time and will not stop that the chip of cutter adds
Work, reduces cutting resistance and the wear extent of cutter, thus extending cutting-tool's used life, due to the big iron filings of chip space not
Easily get lodged in the vicinity of cutter and finished surface, making during Tool in Cutting can directly and absorption surface, thus improve workpiece
Machining accuracy.
Brief description
With specific embodiment, the utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the utility model cutter head end enlarged diagram.
Specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
Slotting cutter as described in Figure 1, including cutter head 1, shoulder 2 and handle of a knife 3, described shoulder 2 one end is connected with handle of a knife 3,
Described shoulder 2 other end is connected with cutter head 1, and described cutter head 1 includes side tool sword 4 and counteredge 5, and described side tool sword 4 is arranged at
Cutter head 1 sidepiece, described counteredge 5 is arranged on cutter head end, and described side tool sword 4 is provided with three and in the shape of a spiral, described side tool sword 4
Between be provided with chip area 6, described counteredge 5 is provided with the first relief angle 7, the second relief angle 8 and the 3rd relief angle 9.The utility model leads to
Cross and the first relief angle 7, the second relief angle 8 and the 3rd relief angle 9 are provided with counteredge 5, described first relief angle is 25 °, after described second
Angle is 67 °, and described 3rd relief angle is 95 °.
The utility model is suitable for the amount of cutting processing greatly, by being provided with the first relief angle on counteredge, after the second relief angle and the 3rd
Angle, increases chip space, so that iron filings is discharged in time, reduces cutting resistance and the wear extent of cutter, thus extending knife
The service life of tool, because the big iron filings of chip space are not easy to get lodged in the vicinity of cutter and finished surface, making can during Tool in Cutting
With direct and absorption surface, thus improve the machining accuracy of workpiece.
The above not imposes any restrictions to this new technical scope, all according to the utility model technical spirit to
On embodiment any modification, equivalent variations and the modification made, all still fall within the range of this new technical scheme.
