Importance of aluminum CNC machining
Aluminum is widely used in the manufacturing industry due to its unique properties, such as light weight, corrosion resistance, and high ductility. In recent years, CNC machining has become a popular method for manufacturing aluminum parts due to its ability to produce complex shapes with high precision and accuracy.
In this blog post, we will discuss the benefits of aluminum CNC machining, including its advantages over other manufacturing processes and the different materials used for aluminum machining. We will also explore how aluminum CNC machining can benefit various industries and provide tips for choosing a CNC machining supplier that fits your needs.
1.What is aluminum CNC machining?
Aluminum CNC machining is the process of producing aluminum parts using CNC machines. CNC machines are computer-controlled machines that use rotating tools to remove material from a workpiece following a predetermined path or set of instructions. Aluminum CNC machining can produce parts with high precision and accuracy, making it a top choice for a variety of industries.
The aluminum CNC machining process begins with a CAD (computer-aided design) drawing of the part to be produced. The CNC machine then interprets the CAD drawing into a program it can understand, instructing the machine to cut and shape the aluminum. CNC machines cut aluminum according to programmed instructions, producing finished parts that meet the required specifications.
Aluminum CNC machining processes include CNC milling, CNC turning, and CNC drilling. CNC milling involves removing material from the surface of the aluminum using a rotating cutting tool, while CNC turning involves removing material from the center of the aluminum by rotating the aluminum relative to the cutting tool. CNC drilling involves drilling holes in the aluminum using a rotating drill.

3.Advantages of aluminum CNC machining
Aluminum is one of the most popular materials for CNC machining projects because of its good physical properties. Its oxidized outer layer prevents it from corroding due to weather, and its strength makes it ideal for mechanical parts. Due to these advantages, aluminum parts are now widely used in all industries, but they are particularly prevalent in the automotive, aerospace, medical, and consumer electronics sectors.
1) Easy to bend
One of the benefits of using CNC machining to make aluminum CNC parts is that they can be easily bent. Unlike steel, aluminum can be easily turned during machining because the thickness of this material allows for the use of various forming methods appropriately. Various shapes of aluminum CNC parts can be easily achieved through pressing and machining.
2) Easy to Machinable
Another advantage of aluminum CNC machining processes is that the material can be easily manufactured through stamping, folding, and drilling. You can use it to form various shapes of parts as needed. The energy required for aluminum CNC machining is much lower compared to steel machining.
3) Low Temperature Resistance
Aluminum is resistant to low temperatures. We all know that steel is fragile, especially in welded parts or low temperature environments. Aluminum is easier to machine at low temperatures compared to steel.
4) Custom Finishing
Aluminum can be customized after machining to meet customer requirements. There are things you can do to give it a perfect custom look. Aluminum CNC parts can be plated in various colors according to your requirements. Some of the colors you can try include black, blue, and green.
5) Machinability
Aluminum is also known for its excellent machinability, which means it can be easily formed using various CNC machining processes such as milling, turning, and drilling. This makes it a popular choice for complex parts that require high precision and accuracy.
6) Cost-effective
Aluminum is an abundant and inexpensive material, making it an affordable choice for many applications. The light weight of aluminum also makes transportation and handling simpler and more cost-effective, thereby reducing overall manufacturing costs.
4.Other manufacturing processes combined with CNC machining
In the actual processing process, considering issues such as quantity, technology, and price, many times we will consider using other processes to obtain semi-finished products first, and then consider using CNC for precision machining. This can greatly save material costs and reduce costs.
Here are several commonly used methods for obtaining semi-finished products:
1) Extrusion + CNC machining
Extrusion is a manufacturing process that involves shaping aluminum into the desired cross-sectional profile. Typically, 6061 aluminum and 6063 aluminum are commonly used materials for extrusion.
2) Die casting + CNC machining
Die casting is a manufacturing process that involves injecting molten metal into a mold to produce complex shapes with high precision and consistency. This method is often used to produce large quantities of complex parts with strict tolerances. But the surface roughness of die castings is very rough, so the surface roughness can be improved by CNC machining.
3) Metal Manufacturing + CNC Machining
When using sheet metal processing, we usually use a CNC bending machine to bend the sheet metal into the desired shape, and then use a CNC machine for precision machining. CNC machines are usually used for cutting, drilling, punching, tapping and contouring sheet metal parts.
By combining these processes, we can significantly improve production efficiency and product accuracy while saving costs and reducing material waste.
4) Forging + CNC Machining
Forging is a manufacturing process in which a forging press or hammer is used to heat and shape the metal through compression force.
Common forging methods include cold forging, hot forging, and warm forging. After forging, CNC machines are generally used for precision machining. Common CNC machining includes milling, turning, drilling, tapping, etc.
5.Industries that benefit from aluminum alloy CNC machining

3) Electronics
Aluminum’s corrosion resistance and anodizing properties make it a popular choice for electronic components such as heat sinks, housing components, brackets, and housings.
4) Medical
CNC machining can produce precise and complex medical parts with tight tolerances, which is essential to ensure the safety and effectiveness of medical devices.
5) Agriculture
Aluminum parts are commonly used in agricultural machinery such as tractors, tillers, and harvesters.
