Description

PCD high-gloss face milling inserts Technical Field

[0001] This utility model relates to the field of milling cutters, and in particular to a PCD high-gloss milling insert. Background Technology

[0002] In existing technologies, aluminum alloys are used in the aerospace and semiconductor industries, optical instrument components, and other aluminum alloy housing joint surfaces, all of which require efficient and high-gloss milling of the surface.

[0003] In this case, it is necessary to ensure both good flatness and high efficiency. Precision planar cutting with high gloss can improve the surface adhesion and refractive properties of aluminum parts, as well as improve fatigue strength and reliability.

[0004] Although the aluminum alloy material of the workpiece is generally soft, it contains a lot of silicon hard particles, making it difficult to machine. The cutting tools are prone to wear and failure, making it difficult to guarantee high precision over a large area of ​​the machined parts, and the workload is large.

[0005] Therefore, conventional carbide inserts are not suitable for high-speed, high-precision, and high-gloss cutting requirements.

[0006] Therefore, the inventors of this application have designed a PCD high-gloss surface milling insert in order to overcome the above-mentioned technical problems. Summary of the Invention

[0008] The present invention solves the above-mentioned technical problems through the following technical solution:

[0009] A PCD high-gloss milling insert is characterized in that the upper cutting edge width is 1.8mm, the upper cutting edge is arc-shaped with a radius of 90mm, and the center distance of the upper cutting edge is 0.94mm.

[0017] According to one embodiment of the present invention, the PCD high-gloss face milling cutter is made of polycrystalline diamond (PCD) material.

[0018] The positive and progressive effects of this utility model are as follows:

Polycrystalline diamond (PCD) material has a very low friction ratio, high temperature resistance, high durability, high resistance to physical wear, high resistance to chemical wear, high resistance to crater wear, high resistance to mechanical wear, and high resistance to cold welding wear, among other excellent properties.

[0021] Second, the PCD cutting tip has a radius of 0.2mm and a clearance angle of 17 degrees, with a reference plane bevel angle of 6 degrees on the right and bottom sides, which can give the cutting tool high contact rigidity and impact resistance.

[0022] At the same time, it can enable PCD inserts to feed quickly for precision cutting, while ensuring a high-quality cutting plane with controllable surface of the aluminum alloy material of the workpiece, and has quite good tool durability.

[0023] Third, the back edge angle is 10 degrees and the cutting edge inclination angle is 15 degrees. This allows for a smaller cutting force while maintaining good cutting edge strength, and effectively avoids cutting interference and chip removal interference, resulting in better workpiece surface quality.
