Abstract
The utility model relates to a three-edge coarse milling cutter for aluminium. The three-edge coarse milling cutter for aluminium comprises a bar and a bit, wherein three end face cutting edges and three corresponding wave edges are arranged at the end of the bit; the wave edges are helical; helical chip grooves are formed between the adjacent wave edges; the helical angles of the chip grooves are 38 degrees; the wave edges are formed by arranging a plurality of concave-convex edges in sequence; 90-degree angles are formed at the joints of two adjacent concave-convex edges; an aluminium-titanium nitride coating is arranged on the surface of the bit. By adopting the structure, the three-edge coarse milling cutter 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 aluminium roughing 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 aluminium roughing milling cutters.
The technical scheme that realizes the utility model object is as follows:
A kind of three sword aluminium roughing milling cutters, comprise knife bar and cutter head, described cutter head end is provided with three face cutting edges and three corresponding wave edges, described wave edge in the shape of a spiral, between adjacent wave edge, be provided with helical form chip area, the helical angle of described chip area is 38 °, and described wave edge is arranged in order and is formed by the concavo-convex sword of multistage, and the junction of described adjacent two concavo-convex swords at an angle of 90.
Described cutter head surface arranges TiAlN coating.
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 schematic diagram of face cutting edge of the present utility model.
Fig. 3 is wave edge structural representation of the present utility model.
In figure: 1 is knife bar, 2 is cutter head, and 3 is face cutting edge, and 4 is wave edge, and 5 is chip area, and 6 is concavo-convex sword.
The specific embodiment
The utility model relates to a kind of three sword aluminium roughing milling cutters, comprise knife bar 1 and cutter head 2, described cutter head 2 ends are provided with three face cutting edges 3 and three corresponding wave edges 4, described wave edge 4 in the shape of a spiral, between adjacent wave edge 4, be provided with helical form chip area 5, the helical angle of described chip area 5 is 38 °, and described wave edge 4 is arranged in order and is formed by the concavo-convex sword 6 of multistage, and the junction of described adjacent two concavo-convex swords 6 at an angle of 90.Described cutter head 2 surfaces arrange TiAlN coating.
