As the requirements for cutting performance increase, all aspects of carbide cutting tools have undergone great changes. Regardless of the product's own performance or the market's requirements for it, businesses are constantly improving their own quality and providing users with high-quality milling cutters. Today, I will tell you about the advantages of carbide cutting tools coating for aluminum and understand our company's high requirements for customized milling cutters.
What are the characteristics of carbide cutting tools coating for aluminum?
1. Hardness
The high surface hardness brought by carbide cutting tools coating for aluminum is one of the ways to improve tool life. Generally speaking, the higher the material or surface hardness of the milling cutter, the longer the lifetime of carbide cutting tools for aluminum. The carbide cutting tools coating for titanium and aluminum nitride carbide has higher hardness than titanium nitride coating.
2. Abrasion resistance
Wear resistance refers to the ability of the coating to resist wear. Although the hardness of some workpiece materials may not be too high, the elements added during the production process and the selected technology may cause the cutting edge of the tool to crack or blunt.
3. Surface lubricity
A high coefficient of friction will increase its cutting heat, resulting in shortened coating life or even failure. And reducing the coefficient of friction can extend the life of aluminum milling cutters to a large extent. The fine and smooth or regular grain aluminum milling cutter coating surface helps to reduce the cutting heat, because the smooth surface can quickly slide the chips away from the rake face and reduce the heat generation. Compared with uncoated tools, coated tools with better surface lubricity can be processed at a higher cutting speed, and then further avoid high temperature welding with workpiece materials.
4. Oxidation temperature
The oxidation temperature refers to the temperature at which the coating begins to differentiate. The higher the oxidation temperature, the more advantageous it is for cutting under high temperature conditions. Although the room temperature hardness of the coating may be lower than that of the coating, it has been proved that it is much more effective in high temperature processing. The reason why the coating can maintain its hardness at high temperatures is that a layer of aluminum oxide can be formed between the tool and the chips, and the aluminum oxide layer can transfer heat from the tool to the workpiece or chips.
5. Anti-adhesion
The anti-adhesion of carbide cutting tools coating for aluminum can prevent or reduce the chemical reaction between the tool and the processed material, and avoid the deposition of workpiece material on the tool. When processing non-ferrous metals (such as aluminum, brass, etc.), built-up edge (BUE) often occurs on the tool, which causes the tool to collapse or the workpiece size is out of tolerance. Once the processed material begins to adhere to the tool, the adhesion will continue to expand.
The above is an introduction to the advantages of our company's aluminum milling cutter coating. From the above, you can understand the characteristics of carbide cutting tools coating. Therefore, you can refer to it when you buy aluminum carbide cutting tools.
