Application of single crystal diamond face milling in mirror polishing process

Application background:

Knobs on equipment panels and high-end audio equipment are usually made of aluminum; in recent years, laptop chassis and some information terminal equipment have also begun to use aluminum. In order to make the product look more cool and cool, the manufacturer usually prints the logo on the chassis or digs the sides of the parts. The gloss of the polished surface has a large effect on the shape of the product, mainly due to the surface roughness and the material of the cutting tool.

problem:

Carbide tools and PCD tools are commonly used to cut aluminum. However, it is impossible to achieve the surface smoothness requirement of the Mirror surface, and it is necessary to perform post-processing such as polishing. Carbide tools and PCD tools are not suitable for cutting ultra-fine shape machining processes. In addition, although carbide tools are inexpensive, they wear and degrade quickly, and tools are frequently updated; therefore, the cost is still not low.

Technical bottleneck:

The mirror polishing process of aluminum chassis has a certain demand in industrial manufacturing;

The high cost of cutting tools during use is associated with lower costs.


Tokyo Diamond uses a single crystal diamond face milling process to effectively improve the surface finish quality of the mirror finish;

Tokyo Diamond uses ultra-fine crystal diamond tools to achieve ultra-fine shape processing;

Tool life is 10 times longer than carbide tools.

Japan's Tokyo Diamond Company developed the Miracle brand single crystal diamond tool for mirror processing of aluminum mirrors and other materials; it can also be used for the processing of photosensitive drums and polygon mirrors.

The Chef Knife also called as a cook kinfe, almost every kitchen can see its figure. Different from other Knife that have special functions, the Kitchen Knife is a knife that can be used in many ways, such as cutting meat as well as vegetables, slicing, shred and so on. The knife  used the good-grade stainless steel material, so that the tool does not rust, with longer service life. We mainly produce all stainless steel chef knives and silicone handle chef knives. We have a variety of specifications chef knife for your choice.
