Description
Technical field
This utility model is related to the cutting tool field of industrial processes, more particularly to a kind of cambered surface profile milling cutter.
Background technology
Milling cutter is the instrument commonly used in machinery production manufacture field, cutting-tool's used life, workpiece surface quality with
And processing stability is the principal element for weighing cutter quality, and the quality of cutter these performances is except relevant with the material of cutter
Outward, the structural parameters of cutter are depended mainly on.
In prior art, in Machining Arc groove operation, first rectangular channel to be milled out in surface of the work using slotting cutter, then be made
Rectangular channel is processed into into arc-shaped slot further with rose cutter, in the course of processing, needs to change cutter and again to knife, so
Since, not only wasting time and energy, work efficiency is relatively low, and due to needing again to knife, easily produces error, so as to affect processing
Precision.Existing cambered surface profile milling cutter, not enough, jump when processing edge strength sword, and workpiece or milling are easily wrapped in during chip removal
On knife, milling cutter is caused to damage, accordingly, it would be desirable to further selection parameter cutter reasonable in design, while meeting the processing of product
Stability in use and the life-span of cutter are required and guarantee, while reducing the cost of cutter.
Utility model content
Goal of the invention of the present utility model is：There is provided one kind in Machining Arc groove, can one-shot forming, machining accuracy
Height, chip removal effect well and can prevent process when spring sword cambered surface profile milling cutter.
The technical solution adopted in the utility model is such：A kind of cambered surface profile milling cutter, including knife bar and cutter head, which is special
Levy and be：The cutter head front end face is provided with three end teeth, and the cutter head side is provided with rake face, side edge major first flank, side
Knife face after sword second, the rake face and side edge major first flank are crossed to form side cutting edge, between the sides adjacent cutting edge
Chip area is provided with, the end tooth is made up of knife face after face cutting edge, end sword major first flank and end sword second, three ends
Face cutting edge is a long end sword and two short end swords, and, by the center on cutter head end face, the short end sword is or not the long end sword
By the center on cutter head end face, transition platform, the face cutting edge between the face cutting edge and side cutting edge, are provided with
For circular shape, between described each end tooth, end tooth chip pocket is provided with.
The end sword is circular arc, and the arc diameter is more than knife bar diameter.
The radius R of the circular arc is 20mm.
The relief angle of the end sword major first flank is 11 °, and after the end sword second, the relief angle of knife face is 18 °.
The relief angle of the side edge major first flank is 13 °, and after the side edge second, the relief angle of knife face is 24 °.
The long 8mm of the side cutting edge.
The knife bar end face is provided with chamfering, and chamfering R is 0.5mm.
In sum, as a result of above-mentioned technical proposal, the beneficial effects of the utility model are：1st, using multi-angle
Edge clearance angle is avoided that the secondary contact of cutter and machined surface, it is ensured that the surface quality and precision of machined surface.2nd, building up by welding
Sword is circular shape, can direct Machining Arc groove, transition platform is provided between face cutting edge and side cutting edge, strengthens knife
Sword intensity, prevents the sword that jumps when processing.3rd, the end tooth chip pocket being provided with is to facilitate chip removal after the sword machined part of end, the row of improve
Bits effect, further prevents from damaging cutter.
