Detailed Description
The present invention will now be further described with reference to the accompanying drawings.
As shown in fig. 1 to 6, an anti-vibration milling cutter includes: a knife handle 1; the cutter head is arranged at one end of the cutter handle 1, a plurality of cutter teeth 2, circumferential blades 3 and chip grooves 4 are arranged on the cutter head, the number of the cutter teeth 2 is odd, bottom blades are arranged on the cutter teeth 2, the intersection of the bottom blades and the circumferential blades 3 is an arc-shaped arc blade 22, and the clearance angle A of the bottom blades is 2.5 degrees.
The bottom blade is provided with a plane blade 21, the plane blade 21 is vertical to the axis of the cutter head, and the plane blade 21 is positioned on one side of the circular arc blade 22.
The length of the flat edge 21 is 5% of the diameter of the tip.
The radius of the arc edge 22 is 0.1-0.5 mm.
The first end tooth back angle B of the bottom blade is 7 degrees, the second end tooth back angle C of the bottom blade is 17 degrees, and the front end tooth angle D of the bottom blade is 5 degrees.
The circumferential edge 3 has a rake angle E of 4 ° and a relief angle F of 8 °.
The helix angle G of the circumferential edge 3 is 35 °.
The circular-arc edge 22 can improve the surface finish of the work.
The flat blade 21 can perform a large surface processing, thereby reducing processing marks and improving surface finish in surface milling.
The odd-number tooth type can effectively inhibit vibration in the machining process, and the plane blade 21 at the cutter point can obtain better surface finish when the surface milling finish machining is carried out. Can be used for processing stainless steel. The vibration-proof milling cutter can be made of hard alloy.
The utility model provides a pair of anti vibration milling cutter has improved the shock resistance through the design reduction vibration of odd number profile of tooth, has improved the surface finish through adopting convex processing sword.
The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the claims of the present invention.
