Diamond-Coated End Mills: Advantages, Applications, And Usage Recommendations
Diamond-coated end mills are special cutting tools that are coated with a synthetic diamond coating. This coating gives the tool greater wear resistance and longer service life when machining hard materials. Here are some details about diamond-coated end mills:
Advantages of Diamond Coating
1.Wear Resistance
- Diamond is one of the hardest materials in nature and has extremely high wear resistance, which means that the tool can stay sharp and reduce wear during high-speed cutting.
2.Long Life
- Due to its excellent wear resistance, diamond-coated tools have a longer service life than uncoated tools.
3.Thermal Stability
- The diamond coating can still maintain its physical properties at high temperatures, which prevents the performance of the tool from decreasing due to temperature increase during high-speed cutting.
4.Suitable for Processing Hard Materials
- Especially suitable for processing high-hardness materials, such as aluminum alloys, copper alloys, and other non-ferrous metal materials.
Applicable Materials
1.Non-Ferrous Metals
- Diamond coating is particularly suitable for processing non-ferrous metal materials, such as aluminum, copper, and their alloys, because these materials tend to adhere to ordinary metal surfaces, causing tool wear.
2.Non-Metallic Materials
- It can also be used to process some non-metallic materials, such as composite materials, plastics, etc.
Usage Restrictions
1.Not Suitable for Processing Iron-Based Materials
- Diamond coatings are prone to chemical reactions when processing iron-based materials, causing the coating to fall off, so it is not recommended for processing iron-based materials such as steel.
2.Temperature Limitations
- Although diamond coatings have good thermal stability, the coating can be damaged at extreme temperatures.
Application Areas
1.Aerospace
- Used in the aerospace industry to manufacture lightweight and high-strength components.
2.Automobile Manufacturing
- Used in the automotive industry to process car bodies, engine parts, etc.
3.Mold Manufacturing
- In the mold manufacturing process, it is used to process high-precision mold parts.
Selection and Usage Recommendations
1.Material Match
- Make sure the tool coating you choose is appropriate for the type of material you want to machine.
2.Proper Cooling
- Although diamond coatings have good thermal stability, the use of proper coolant is still recommended in some cases to extend tool life.
3.Correct Cutting Parameters
- Use appropriate cutting speeds and feed rates to get the most out of your tool.
