The Role of Colorful Coating for Single Flute End Mills

‌

The durability of the single-edge aluminum milling cutter with colorful coating is more than 50%, which is more than 50% higher than the ordinary one. The single-edge design is sharper, and there is no problem in slotting, drilling or processing locking.

Colorful colors, effectively reduce the probability of needle breakage, prevent coated drill needles from sticking, improve dust removal, etc.

Coated tools are prepared by coating a thin layer of refractory metal or non-metallic compound with good wear resistance (can also be coated on superhard material blades such as ceramics, diamonds and cubic boron nitride) on the surface of cemented carbide or high-speed steel (HSS) substrate with good strength and toughness by vapor deposition method.

The coating acts as a chemical barrier and thermal barrier, reducing the diffusion and chemical reaction between the tool and the workpiece, thereby reducing the wear of the substrate. Coated tools have the characteristics of high surface hardness, good wear resistance, stable chemical properties, heat and oxidation resistance, low friction coefficient and low thermal conductivity. When cutting, the life of uncoated tools can be increased by more than 3 to 5 times, the cutting speed can be increased by 20% to 70%, the processing accuracy can be increased by 0.5 to 1 level, and the tool consumption cost can be reduced by 20% to 50%.

Coated tools have become the symbol of modern cutting tools, and the proportion of use in tools has exceeded 50%. Various tools used in cutting processing

In the manufacturing process of coated tools, high hardness, good wear resistance, stable chemical properties, no chemical reaction with the workpiece material, heat resistance and oxidation resistance, low friction factor, and strong adhesion to the substrate are required. Among them, the oxidation resistance of the coating is the technical condition most directly related to the cutting temperature.

The role of colorful milling cutters in aluminum alloy processing

1. Improve processing efficiency: Colorful coating can reduce cutting force and cutting temperature, thereby improving the processing efficiency of aluminum alloy. This means that using colorful milling cutters can complete more work in the same amount of time, greatly improving production efficiency.

2. Enhance wear resistance: Colorful coating can effectively resist the wear generated during aluminum alloy processing and extend the service life of the tool. This not only reduces the frequency of tool replacement, but also reduces production costs.

3. Improve corrosion resistance: During aluminum alloy processing, the tool is susceptible to chemical corrosion. The colorful coating can effectively resist corrosive substances and protect the tool from damage, thereby ensuring processing quality and durability of the tool.
