Abstract
The utility model provides a compound milling cutter of centering chamfer, including milling cutter stalk portion (1) and cutting edge head (2), wherein, set up the spiral cutting edge that the 4 -6 strip has cutting chamfer function on the circular conical surface of cutting edge head (2), only remain 2 spiral cutting edge on the top of cutting edge head (2), wear into the spotter form. This compound milling cutter of centering chamfer has the function of machining center hole and chamfer concurrently to have the production efficiency height, the tool life is long, the stable characteristics of feeling relieved.
Description
Technical field
The utility model relates to a kind of metal cutting process cutter field.
Background technology
In metal cutting process, often can use pilot drill machining center hole, conventional pilot drill, be commonly called as centre drill, material is carbide alloy or high-speed steel, and blade number is 2 swords; Often can make orifice chamfer and edge chamfering with angle cutting tool, the rose reamer of conventional high-speed steel, blade number is 4 swords, does not have the function of pilot drill.In most cases centering and chamfering two procedures need with two cutters.Although some pilot drill can utilize side edge to carry out chamfering, because cutting edge is single-blade or two swords, production efficiency is low, and machined surface roughness is large.
Summary of the invention
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of centering chamfer composite milling cutter, the function of pilot drill and rose reamer is united two into one.
Another object of the present utility model, is to provide a kind of milling cutter higher than the angle cutting tool production efficiency of standard.
To achieve these goals, the technical scheme that the utility model adopts is as follows: a kind of centering chamfer composite milling cutter, comprise milling cutter shank and cutting edge head, wherein, the taper seat of cutting edge head arranges 4-6 bar there is the spiral cutting edge cutting chamfering function, only retain 2 spiral cutting swords on the top of cutting edge head, wear into pilot drill shape.
Concrete, described cutting edge head is made into the tapering of 60 ° or 90 °, and tapering also can be determined according to workpiece; Described spiral cutting cutlery has the helical angle of 10 °-25 °.
The diameter of described milling cutter shank is between Φ 10-Φ 16.
Compared to prior art, the technical advantage of centering chamfer composite milling cutter of the present utility model is:
1. the utility model composite milling cutter, is different from pilot drill and chamfer drill, also non-the two cutlery simple
Superposition, it is the composite milling cutter with a cutter two kinds of functions.
2. this cutting edge roundness is sharp, and rigidity is strong, and durability is long;
3. to have production efficiency high for this cutter, the performance that roughness is low.
Accompanying drawing explanation
Fig. 1 is the overall schematic of centering chamfer composite milling cutter of the present utility model.
Fig. 2 is the top view of the cutting edge head based on the centering chamfer composite milling cutter shown in Fig. 1.
Fig. 3 is for based on the side view shown in Fig. 1.
Number in the figure illustrates: 1. milling cutter shank, 2. cutting edge head, 3. chamfering spiral cutting edge, and 4. centering uses spiral cutting sword, a. taper seat tapering, b. pilot drill axial rake, c. angle cutting tool helical angle.
Detailed description of the invention
See shown in Fig. 1 to Fig. 3, a kind of centering chamfer composite milling cutter of the present utility model, comprises milling cutter shank 1 and cutting edge head 2, determines needed for operating shape, cutting edge head 2 is made into the tapering of 60 ° or 90 °, or other tapering; Taper seat has 4-6 bar helical edges, such as, the bite head with the tapering of taper seat tapering a=90 ° shown in Fig. 1, there is the function of cutting chamfering; Only retain two spiral cutting swords on the top of cutting edge, wear into pilot drill shape, there is turning centre hole and use.
Shown in composition graphs 1 and Fig. 3, form pilot drill by centering spiral cutting cutter 4, pilot drill axial rake b is 5 °.Shown in composition graphs 2 and Fig. 3, form angle cutting tool by chamfering spiral cutting edge 3, angle cutting tool helical angle c is 10 °.
Described in comprehensive: this centering chamfer composite milling cutter is applied in CNC machine, not only shortens tool change time, also can vacate a merit position on CNC tool magazine.By other cutter of dress, certain practicality and economy can be had.
Due to composite milling cutter of the present utility model, cutter material is fine grained carbide alloy YL10.2.And there is helical angle, add cutting anterior angle, therefore cut easily than conventional criteria rose reamer, it more bores than with center for standard, and side edge chamfering efficiency is high.Sword-6, middle and upper part 4 sword of this composite milling cutter, bite head is only 2 swords, grinds into pilot drill shape, and therefore chip groove space is large, and sharpening is convenient, processes centre bore, and location is correct, and cutting edge is sharp, and production efficiency is high, and tool life is long.
Use the utility model milling cutter, can on the materials such as non-ferrous metal, casting pig, carbon steel, steel alloy drill centers and chamfering.
Schematically above be described the utility model and embodiment thereof, this description does not have restricted, and also just one of the embodiment of the present utility model shown in accompanying drawing, actual structure is not limited thereto.So; if those of ordinary skill in the art enlightens by it; when not departing from the utility model and creating aim; the frame mode similar to this technical scheme and embodiment is designed without creationary; such as diameter change, tapering change etc., all should belong to protection domain of the present utility model.
Claims (3)
1. a centering chamfer composite milling cutter, comprise milling cutter shank (1) and cutting edge head (2), it is characterized in that: 4-6 bar is set on the taper seat of cutting edge head (2) there is the spiral cutting edge cutting chamfering function, only retain 2 spiral cutting swords on the top of cutting edge head (2), wear into pilot drill shape.
2. centering chamfer composite milling cutter as claimed in claim 1, is characterized in that: described cutting edge head (2) is made into the tapering of 60 ° or 90 °.
