224. Efficient tool die cutting requirements

Epoch is now developing deep-cutting deep corner cutter cutting production to prevent flutter. In order to further improve processing efficiency into the 1, using the inverted cone design. This design prevents the cutting tool during the bending caused by the peripheral cutting edge and being contact with the material, which can realize stable processing. In addition, the tool coating used with high hardness and high heat resistance, wear resistance TH <TiSiN> hard coating, is very suitable for high hardness materials, direct deep-cutting.

End cutter cutting residual part of the existing theory, especially the cutting speed and low end of the chisel edge prone to breakage. The mill process is usually rounded to form a set of cutting surface, it has the advantages of stable and reliable process.

The following examples introduced by processing mills Epoch deep cut features rounded corners.

The deep cutting of high hardness materials
Type milling cutter with a long neck from the processing SKD11 Cold plastic molds Steel <60HRC> The results can be seen, the ball end cutter is very cutting edge of peripheral damage; and Epoch processing fillet cutter is not damaged, only the uniform wear. Can be inferred, as the ball end cutter cutting edge contact length of the larger, so the cutting resistance is also large, high cutting speed peripheral cutting edges easily damaged. This is 1 point and the case 1, the same, round cutter has obvious advantages.
Under the same processing conditions by the Hitachi tool rounded corner end mill cutter with other companies can see the contrast, the other rounded end mills produced by the absence of inverted cone design, high over 60HRC hardness of materials processing effect is not very satisfactory. Hitachi tools deep cutting of the new generation of fillet 1 mill because the use of the unique shape of anticlinal type design, peripheral cutting edge for the point-contact cutting, even in direct Qiefa Jia workers with high hardness materials, the cutting resistance is small , and the processing state stability.
