Description

An end milling tool for high-gloss aluminum

technical field

The utility model relates to the technical field of milling cutters, in particular to an end milling cutter for high-gloss aluminum.

Background technique

The use of new materials in modern machining is becoming more and more widespread, among which the use of aluminum materials is more common, and it has already accounted for a large share as a raw material in machining. Aluminum materials have been widely used in large industries such as aviation, automobiles, and electronics, replacing the use of traditional raw material iron. For the characteristics of aluminum, modern machining has higher and higher processing requirements for it. The main reason is that the processing speed must be high, which is more than 2 to 3 times that of processing iron, and the appearance must be bright without any defects. Ordinary milling cutters can no longer Meet the requirements of high-efficiency processing and high-gloss appearance of products.

Utility model content

In order to solve the above problems, the utility model discloses an end milling tool for high-gloss aluminum.

The technical scheme that the utility model adopts for realizing the above object is:

An end milling tool for high-gloss aluminum, characterized in that: it includes a tool body, the tool body is provided with three blades, the edge of the blade includes a rake face and a flank, and the rake face and the flank The blade surface is ground by an ultra-fine grain grinding wheel to form a mirror surface; the edge of the blade is provided with a passivation arc.

The radius of the passivation arc is 0.005mm.

The blunt arc of the cutting edge is tangent to the plane where the flank is located.

The flank is provided with a first flank, a second flank and a third flank, an obtuse angle a is set between the first flank and the second flank, and the second flank There is an obtuse angle b between the third flank and the third flank;

The blunt circular arc of the cutting edge is tangent to the first flank.

The rake face is a concave arc surface.

The center of the passivation arc of the edge of the blade is located inside the edge of the blade, and the line connecting the point of tangency between the first flank and the passivation arc and the center of the circle is perpendicular to the first flank.

The utility model has the advantages that: the cutting edge of the utility model is provided with a blunt circular arc, which is more suitable for high-speed milling and cutting with the special front and rear cutter face structures. Its processing speed is three times that of ordinary milling cutters, and The mouth is sharp, no shock marks, no flaws and chipping. The processed workpiece has high precision and good finish. The product finish can achieve a mirror effect. The tool itself has been mirror-polished on the surface, so that the service life of the tool will be longer.

The processed workpiece has high precision and good finish. The finish of the product can reach the mirror effect. There is no need to polish the product again, which reduces the environmental dust pollution caused by polishing, reduces the health damage to workers, saves production costs, and realizes environmental protection and green production. .

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.
