Problems solved by technology

[0002] When processing difficult-to-cut materials such as stainless steel and titanium alloys, due to the existence of the height difference, the cutting tool is at the point of the hand, which will cause a certain vibration phenomenon, and at the same time, the stress environment of the cutting tool blade is not good, and it is easy to cause damage; In addition, the outer diameters of the shank and the blade of traditional end mills are generally the same, but the shank is only used for clamping, and the same outer diameter of the shank and the blade causes waste of materials; Easy to slip and loose when clamping

Embodiment Construction

[0010] refer to figure 1 , a kind of end milling cutter, comprises cutting part and shank part, and cutting part is provided with helical cutting edge, and described cutting edge is curved surface structure, and the edge part on cutting edge is set to the structure of unequal helix angle; Said cutting The surface is coated with a layer of aluminum oxide titanium coating.

[0011] The middle part of the handle is provided with an annular slot.

[0012] The outer diameter of the shank is smaller than the outer diameter of the cutting part.

[0013] The invention adopts the curved cutting edge and unequal helix angle which can suppress the height difference of the vertical surface processing, effectively suppresses the high-frequency vibration, and improves the stability when the tool is processed; the middle part of the shank is provided with an annular slot, which is convenient for the chuck to hold the tool , and the clamping is relatively firm and not easy to loosen; the ou...

Abstract

The invention discloses an end milling cutter which comprises a cutting portion and a handle portion. The end milling cutter is characterized in that a spiral cutting edge is arranged on the cutting portion which is of a curved-surface structure, and an edge portion of the cutting edge is of an unequal helical angle structure; the cutting portion is coated with titanium aluminum oxide. The curved-surface cutting edge and the unequal helical angle structure which can prevent a machining height difference of a vertical surface are adopted, the high-frequency vibration can be effectively inhibited, and the stability of the end milling cutter during machining is improved; an annular clamping groove is formed in the middle of the handle portion so that a chuck can clamp the cutter conveniently and firmly, and the chuck is unlikely to loose; the outer diameter of the handle portion is smaller than that of the cutting portion, materials are reduced and the manufacturing cost of the milling cutter is reduced.

Description

technical field [0001] The invention relates to the field of machining, in particular to an end mill. Background technique [0002] When processing difficult-to-cut materials such as stainless steel and titanium alloys, due to the existence of the height difference, the cutting tool is at the point of the hand, which will cause a certain vibration phenomenon, and also make the stress environment of the cutting tool edge not good, which is easy to cause damage; In addition, the outer diameters of the shank and the blade of traditional end mills are generally the same, but the shank is only for clamping, and the same outer diameter of the shank and the blade causes waste of materials; It is easy to slip and loosen when clamping. Contents of the invention [0003] The object of the present invention is to provide an end mill that is relatively stable and easy to clamp during processing. [0004] The present invention is achieved through the following technical solutions: an...
