Abstract

The utility model relates to a tool used for machining of a milling machine, in particular to a finish milling cutter with a side-cutting edge, which comprises a cutter head, a cutter bar and a cutter arm. The cutter bar is provided with a scrap discharging groove; the cutter head is provided with a pair of main cutting blades which are in central symmetry; the cutter head is provided with a pair of slick side edges; and the outside diameters of the slick side edges are larger than the outside diameters of the main cutting blades by 0.01 to 0.02 mm. The finish milling cutter saves human and material resources and improves the working efficiency.

Description

Band front cutting edge finish-milling cutter
Technical field
The utility model relates to a kind of a kind of cutter that is used for milling machine processing that has, and particularly is with front cutting edge finish-milling cutter.
Background technology
Blade shapes has a variety of, plain-milling machine and CNC milling machine working groove and outline of straight line, mills processing cavity on the boring machining center, core, curved profile, profile and uses.Now more milling cutter is applied in hole processing and die cavity processing, to carry out roughing earlier generally speaking man-hour adding, change milling cutter then and carry out semifinishing, and then change milling cutter and carry out fine finishining, such operation just can achieve the goal, such operation needs often to change milling cutter, and it is loaded down with trivial details to work, inefficiency.
Goal of the invention
At needing often to change milling cutter in the above-mentioned technology, it is loaded down with trivial details to work, and the shortcoming of inefficiency provides a kind of band front cutting edge finish-milling cutter.
The realization the technical solution of the utility model is as follows:
Band front cutting edge finish-milling cutter, it comprises cutter head, knife bar, handle of a knife, has chip area on the knife bar, has a pair of centrosymmetric main cutting edge on the cutter head, cutter head is provided with the secondary sword of a pair of smoothing, and the external diameter of the secondary sword of smoothing is than the big 0.01mm of external diameter---the 0.02mm of main cutting edge.
The secondary sword of described smoothing is 30 ° to the extended line and the angle β of main cutting edge between the extended line of central point of central point, and this is to the secondary sword of smoothing center symmetry.
Use above technology, front cutting edge finish-milling cutter, it comprises cutter head, knife bar, handle of a knife, has chip area on the knife bar, have a pair of centrosymmetric main cutting edge on the cutter head, cutter head is provided with the secondary sword of a pair of smoothing, and the external diameter of the secondary sword of smoothing is than the big 0.01mm of external diameter---the 0.02mm of main cutting edge, the secondary sword of smoothing is 30 ° to the extended line and the angle β of main cutting edge between the extended line of central point of central point, and this is to the secondary sword of smoothing center symmetry., and this is to the secondary sword of smoothing center symmetry, and the utility model carries out the rough machined while at main cutting edge, and the secondary sword of smoothing carries out the fine finishining of little surplus, can time processing go out needed product, and the resource that uses manpower and material resources sparingly is increased work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to schematic diagram;
Among the figure: 1, cutter head, 2, knife bar, 3, handle of a knife, 4, chip area, 5, main cutting edge, 6, the secondary sword of smoothing.
The specific embodiment
As shown in Figure 1 and Figure 2, band front cutting edge finish-milling cutter, it comprises cutter head 1, knife bar 2, the handle of a knife 3 of carbide alloy system, has chip area 4 on the knife bar 2, have a pair of centrosymmetric main cutting edge 5 on the cutter head 1, cutter head 1 is provided with the secondary sword 6 of a pair of smoothing, and the external diameter of the secondary sword 6 of smoothing is than the big 0.01mm of external diameter of main cutting edge 5, the secondary sword 6 of smoothing is 30 ° to the extended line and the angle β of main cutting edge 5 between the extended line of central point of central point, and this is to the secondary sword of smoothing center symmetry., this is to the secondary sword of smoothing center symmetry.The utility model carries out the rough machined while at main cutting edge 5, and the secondary sword 6 of smoothing carries out the fine finishining of little surplus, can time processing go out needed product, and the resource that uses manpower and material resources sparingly is increased work efficiency.
