Position between body and lower point of a knife, chip space are in invaginated type；The main purpose so set be in order to, on the one hand, when milling straight-tooth
Cutter during milling straight-tooth, by chip space discharged by generated chip, and chip space primarily serves the purpose of chip removal chip；
On the other hand, during milling straight-tooth cutter at high speeds rotates, generated centrifugal force forms powerful air quantity eddy flow, reduces
The temperature of milling straight-tooth cutter in itself.
The top of the cutter hub frustum is fixedly installed curved blade, and curved blade is invaginated type, and curved blade surrounds knife
There are three the fixed settings of body frustum, and three curved blades are triangular in shape to be symmetrical arranged, and cutter hub frustum both sides of the edge line is formed
Angle is 60 °；The main purpose so set is in order to which it is 60 ° straight directly disposably to mill out angle similary with cutter hub frustum
Tooth forms the recessed bottom surface circular arc of straight-tooth；Curved blade is invaginated type, and curved blade is fixedly installed three around cutter hub frustum
A, three curved blades are triangular in shape to be symmetrical arranged；The main purpose so set is in order to more convenient in cutter hub frustum
Top constant radius nose frustum primarily serves stable, securely connection point of a knife frustum effect；Simultaneously existed to enhance cutter hub frustum
Participate in cutting force during cutting.
Beneficial effects of the present invention：The technical program provides a kind of cutter of milling straight-tooth, and design structure is simple, science is closed
Reason, it is easy to use efficient；When can solve gear-shaping processing, since processing impact force is big, equipment lateral clearance is big, space width error
Greatly, the problem of machining accuracy of straight-tooth is not high, while also solve using gear hobbing process straight-tooth, it is necessary to customized molding cutter, into
The problem of this is high；The machining accuracy of straight-tooth is substantially increased, reduces the processing cost of small lot processing straight-tooth.
