Abstract
The invention relates to a four-edged round nose end milling cutter. The cutter comprises a cutter rod and a cutter head, the cutter head is provided with four side cutting edges and four corresponding end edges, the side cutting edges are spiral in shape, the spiral angle of each of the side cutting edges is 46DEG, an arc is arranged between the side cutting edges and the end edges, the radius R of the arc is 2.8mm, the first clearance angle, the second clearance angle and the anterior angle of each of the end edges are 5DEG, 15DEG and 7DEG respectively, and a spiral chip discharging slot is arranged between adjacent two cutting edges. The surface of the cutter head is provided with a titanium aluminum nitride coating. The four-edged round nose end milling cutter adopting the above structure has the advantages of smooth chip discharging, avoiding of the edge collapsing phenomenon caused by too sharp cutter tips during the milling cutter processing by arranging the arc between the side cutting edges and the end edges, and prolonged service life.
Description
Technical field
The present invention relates to a kind of milling cutter, particularly a kind of four sword round nose slotting cutters.
Background technology
In machining, need to adopt milling cutter to mill out end face, inclined-plane, groove and step surface to different workpiece.Existing slotting cutter is when carrying out milling to workpiece, and the metal fillings milled out not easily is discharged, and easily gets lodged near cutter and machined surface, affects machining accuracy and the quality of workpiece, also can produce certain wearing and tearing to cutter simultaneously, reduces cutting-tool's used life.
Summary of the invention
The object of this invention is to provide the four sword round nose slotting cutters that a kind of chip removal easily, not easily produces tipping, enhances productivity.
The technical scheme realizing the object of the invention is as follows:
A kind of four sword round nose slotting cutters, comprise knife bar and cutter head, described cutter head is provided with four side cutting edges and four corresponding end swords, and in the shape of a spiral, the helical angle of described side cutting edge is 46 ° to described side cutting edge, between described side cutting edge and end sword, arc transition is set, the radius R of described circular arc is 2.8mm, and end sword first relief angle of described end sword is 5 °, and end sword second relief angle is 15 °, end angle of cutting edge is 7 °, is provided with helical form chip area between described survey cutting edge.
Described bit interface arranges TiAlN coating.
After adopting said structure, chip removal of the present invention is more smooth and easy, and side cutting edge arranges arc transition milling cutter with end sword and adds the phenomenon that man-hour, tipping occurred because point of a knife is too sharp, adds the service life of milling cutter.
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 end sword schematic diagram of the present invention.
Fig. 3 is end sword partial schematic diagram 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
By a kind of four sword round nose slotting cutters of the known the present invention of Fig. 1 to Fig. 3, comprise knife bar 1 and cutter head 2, described cutter head 2 is provided with four side cutting edges 3 and four 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 46 °, between described side cutting edge 3 and end sword 4, arc transition is set, the radius R of described circular arc is 2.8mm, end sword first relief angle 6 of described end sword 4 is 5 °, end sword second relief angle 7 is 15 °, end angle of cutting edge 8 is 7 °, is provided with helical form chip area 5 between described survey cutting edge 3.Described cutter head 2 surface arranges TiAlN coating.
