Abstract
The utility model relates to a kind of helicla flute groove milling cutter, comprises cutter hub and cutting edge, and cutting edge adopts three tooth Double-blade structures, and the teeth groove of cutting edge adopts sped structure, and helical angle is 30 °-35 °, and the anterior angle of milling cutter is 0 °, and relief angle is 12 °.The teeth groove of cutting edge adopts spiral form design, and effectively decrease cutter and contact with the continuous lines of part to be processed, make cutter and part to be processed continue interrupted Point contact machining, processing steadily, is vibrated little, effectively disperseed cutting force on the impact of cutter.
Description
Technical field
The utility model relates to a kind of milling cutter, and particularly a kind of three tooth helicla flute groove milling cutters, belong to field of machining.
Background technology
The processing of ring slot often can be run in current Milling Processes; the connection of 90 ° of cannelures has just been used in connection as modal inserted wire rod quality cutter head and milling cutter body; usual cannelure straight-tooth groove milling cutter processing; cutter and machined material are continuous print linear contact lay; the resistance that cutter is subject to is larger; when processing cannelure; milling tool speed lower and easily there is cutter breakage phenomenon and make surface of the work occur deeply gnaw phenomenon; milling cutter is mainly anterior angle cutting when processing parts; tool wear is fast, needs frequent reconditioning.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of helicla flute groove milling cutter, be specifically designed to processing 90 ° of cannelures, the teeth groove of milling cutter adopts spiral form design, effectively decreases cutter and contacts with the continuous lines of part to be processed, make cutter and part to be processed continue interrupted Point contact machining, processing steadily, vibrate little, effectively disperseed cutting force on the impact of cutter, the relief angle of cutter is main cutting tip, tool wear is slow, reduces cutter grinding number of times.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of helicla flute groove milling cutter, comprise cutter hub and cutting edge, it is characterized in that: cutting edge adopts three tooth Double-blade structures, the teeth groove of cutting edge adopts sped structure, helical angle is 30 °-35 °, and the anterior angle of milling cutter is 0 °, and relief angle is 12 °.The teeth groove of cutting edge adopts spiral form design, effectively decrease cutter to contact with the continuous lines of part to be processed, cutter and part to be processed is made to continue interrupted Point contact machining, processing steadily, vibrate little, effectively disperseed cutting force on the impact of cutter, the relief angle of cutter is main cutting tip, tool wear is slow, reduces cutter grinding number of times.
The beneficial effect that the utility model brings is: 1, cutter adopts helical design, increases appearance bits, the chip removal ability of cutter, reduces chip and twine cutter phenomenon, significantly can improve the Milling Speed of cutter when processing parts, improve working (machining) efficiency.
2, the cutting edge of milling cutter adopts three toothings that cutter solid section is increased, and effectively raises the intensity of cutter, makes cutter can not because of the phenomenon of the torsion of the stressed excessive generation of single cutting edge.

Detailed description of the invention
A kind of helicla flute groove milling cutter, comprise cutter hub and cutting edge 1, cutting edge 1 adopts three tooth Double-blade structures, and the teeth groove of cutting edge 1 adopts sped structure, and helical angle 4 is 30 °-35 °, and the anterior angle 5 of cutter hub is 0 °, and relief angle 3 is 12 °.The teeth groove of cutting edge 1 adopts spiral form design, effectively decrease cutter to contact with the continuous lines of part to be processed, cutter and part to be processed is made to continue interrupted Point contact machining, processing steadily, vibrate little, effectively disperseed cutting force on the impact of cutter, the relief angle 3 of cutter is main cutting tip, tool wear is slow, reduces cutter grinding number of times.Helicla flute groove milling cutter is when processing parts, and stable cutting, not easily occur forging a knife, squeezing cutter phenomenon, increase the chip pocket of cutter, cutter chip removal when Milling Process is smooth and easy, not easily twines cutter simultaneously.Adopt the design of three tooth twolips, meet the relief grinding requirement of screw grinder, give the withdrawing space that emery wheel is enough.The design of the number of teeth ensure that solid diameter size and the durability of cutter.Effectively raise cutter process annular groove time add work efficiency.
