The utility model relates to a three-edge end mill for aluminium. The three-edge end mill for aluminium comprises a bar and a bit, wherein the bit is provided with three side cutting edges and three corresponding end edges; the side cutting edges are helical; the helical angles of the side cutting edges are 55 degrees; helical chip grooves are formed between the side cutting edges; first clearance angles of the end edges are 6 degrees; second clearance angles of the end edges are 15 degrees; rake angles of the end edges are 9 degrees; an aluminium-titanium nitride coating is arranged on the surface of the bit; the diameter d of the bar is 6-20mm; the axial length L1 of the bit is 8-50mm; the axial total length L of the three-edge end mill for aluminium is 50-100mm. By adopting the structure, the three-edge end mill for aluminium can efficiently process aluminium products and is not easy to wear, thus prolonging the service life of the cutter and reducing the processing cost.
Description
Technical field
The utility model relates to a kind of milling cutter, particularly a kind of three sword aluminum end milling cutters.
Background technology
In machining, cutter is the indispensable critical piece of machine tooling, and the quality of cutter quality has influence on the service life of self, also has influence on quality and the production efficiency of machining.Aluminium is being added to man-hour, because aluminium hardness is softer, when cutting, easily sticky cutter, causes cutting resistance large, and tool wear is serious, and cutting speed is slow, and cutter easily damages, and the problems such as burr appear in surface of the work.
Summary of the invention
The purpose of this utility model is to provide a kind of energy high efficiency processing aluminum materials nonabradable three sword aluminum end milling cutters.
The technical scheme that realizes the utility model object is as follows:
A kind of three sword aluminum end milling cutters, comprise knife bar and cutter head, described cutter head is provided with three side cutting edges and three corresponding end swords, described side cutting edge in the shape of a spiral, the helical angle of described side cutting edge is 55 °, between described side cutting edge, is provided with helical form chip area, and end sword first relief angle of described end sword is 6 °, end sword the second relief angle is 15 °, and end angle of cutting edge is 9 °.
Described cutter head surface arranges TiAlN coating.
The diameter d of described knife bar is between 6-20mm.
The axial length L 1 of described cutter head is between 8-50mm.
The axial overall length L of described three sword aluminum end milling cutters is between 50-100mm.
Adopt after said structure the utility model processing aluminum materials expeditiously, not easy to wear, increased service life of cutter, reduced processing cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of end sword of the present utility model.
Fig. 3 is the partial schematic diagram of the utility model cutter end.
In figure: 1 is knife bar, 2 is cutter head, and 3 is side cutting edge, and 4 is end sword, and 5 is chip area, and 6 is end sword the first relief angle, and 7 is end sword the second relief angle, and 8 is end angle of cutting edge.
The specific embodiment
By the known the utility model three sword aluminum end milling cutters of Fig. 1 to Fig. 3, comprise knife bar 1 and cutter head 2, described cutter head 2 is provided with three side cutting edges 3 and three corresponding end swords 4, described side cutting edge 3 in the shape of a spiral, the helical angle of described side cutting edge 3 is 55 °, between described side cutting edge 3, be provided with helical form chip area 5, end sword first relief angle 6 of described end sword 4 is 6 °, and end sword the second relief angle 7 is 15 °, and end angle of cutting edge 8 is 9 °.Described cutter head 2 surfaces arrange TiAlN coating.The diameter d of described knife bar 1 is between 6-20mm.The axial length L 1 of described cutter head 5 is between 8-50mm.The axial overall length L of described three sword aluminum end milling cutters is between 50-100mm.
Enumerate the concrete size of several cutters below:
Cutter one, knife bar diameter d is 4mm, and cutter head axial length L 1 is 8mm, and three sword aluminum end milling cutter overall length L are 50mm.
Cutter two, knife bar diameter d is 12mm, and cutter head axial length L 1 is 32mm, and three sword aluminum end milling cutter overall length L are 75mm.
Cutter three, knife bar diameter d is 16mm, and cutter head axial length L 1 is 50mm, and three sword aluminum end milling cutter overall length L are 100mm.
