Abstract
The invention relates to a three-edged milling cutter for aluminum. The cutter comprises a cutter rod and a cutter head, the cutter head is provided with three side cutting edges and three corresponding end edges, the side cutting edges are spiral in shape, the spiral angle of each of the side cutting edges is 44DEG, a spiral chip discharging slot is arranged between adjacent two side cutting edges, and the first clearance angle, the second clearance angle and the anterior angle of each of the end edges are 6DEG, 16DEG and 6DEG respectively. The surface of the cutter head is provided with a titanium aluminum nitride coating. The diameter d of the cutter rod is 4-20mm. The axial length L1 of the cutter head is 5-50mm. The axial total length L of the three-edged milling cutter for aluminum is 50-100mm. The three-edged milling cutter for aluminum adopting the above structure has the advantages of efficient aluminum processing, difficult abrasion, prolongation of the service life of the cutter, and processing cost reduction.
Description
Technical field
The present invention relates to a kind of milling cutter, particularly a kind of three sword aluminium 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.Adding man-hour to aluminium, because aluminium hardness is softer, easily gluing cutter when cutting, cause cutting resistance large, 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 object of this invention is to provide a kind of energy high efficiency processing aluminum materials and nonabradable three sword aluminium milling cutters.
The technical scheme realizing the object of the invention is as follows:
A kind of three sword aluminium 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 44 °, is provided with helical form chip area between the cutting edge of described side, and end sword first relief angle of described end sword is 6 °, end sword second relief angle is 16 °, and end angle of cutting edge is 6 °.
Described bit interface arranges TiAlN coating.
The diameter d of described knife bar is between 4-20mm.
The axial length L 1 of described cutter head is between 5-50mm.
The axial overall length L of described three sword aluminium milling cutters is between 50-100mm.
To adopt after said structure the present invention can processing aluminum materials expeditiously, not easy to wear, add cutting-tool's used life, reduce processing cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of end sword of the present invention.
Fig. 3 is the partial schematic diagram of cutter ends of the present invention.
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 first relief angle, and 7 is end sword second relief angle, and 8 is end angle of cutting edge.
Detailed description of the invention
Knife bar 1 and cutter head 2 is comprised by Fig. 1 to Fig. 3 known the present invention three sword aluminium milling cutter, 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 44 °, helical form chip area 5 is provided with between described side cutting edge 3, end sword first relief angle 6 of described end sword 4 is 6 °, and end sword second relief angle 7 is 16 °, and end angle of cutting edge 8 is 6 °.Described cutter head 2 surface arranges TiAlN coating.The diameter d of described knife bar 1 is between 4-20mm.The axial length L 1 of described cutter head 2 is between 5-50mm.The axial overall length L of described three sword aluminium milling cutters is between 50-100mm.
Enumerate the concrete size of several cutter below:
Cutter one, knife bar diameter d is 4mm, and cutter head axial length L 1 is 5mm, and three sword aluminium milling cutter overall length L are 50mm.
Cutter two, knife bar diameter d is 10mm, and cutter head axial length L 1 is 30mm, and three sword aluminium milling cutter overall length L are 75mm.
