What are the Features of Aluminum’s Machining Services

by Sebastian

Aluminum is very recyclable, enabling companies to use construction materials made from finished goods. That are abandoned after their useful lives as well as and stainless steel waste produced during machining processes. The mechanical and thermal properties of aluminum as a material are noteworthy. Additionally, aluminum metal is relatively easy to form, particularly during drilling operations like CNC aluminum machining.

In contrast to other lighter metals like magnesium and titanium alloys, we actually regard aluminum alloy in high regard. The production and distribution of CNC automobile parts and other lightweight CNC parts has increased significantly, as has the use of CNC aluminum. Comparatively speaking to some other forms of metal, aluminum is simple to machine.

Certain Aspects of Consideration for Metal Machinability

Here we will discuss a few aspects that have a big impact on this metal’s machinability. For a variety of industrial applications, cnc aluminum Machine provides a broad range of machining services, including those involving aluminum machining.

The Metal

The first factor is the metal itself, specifically its alloy, homogeneity of mechanical qualities, and microstructure. The internal composition of the metal determines the uniformity of the machining.

Machining Techniques

The second component is the actual machining procedure. This method considers the required lubricants, feed rates, cutting speeds, and cutting tools.

Materials Handling

The third factor is the processing of the materials. The extrusion press, die design, reduction ratio, heat treatment, alloy chemistry, and extrusion process controls for aluminum are all covered in this.

Electrical Conductivity

Compared to other commonly machined metals like carbon steel (7 million Siemens/meter) and stainless steel (150,000 Siemens per meter), aluminum has a higher electrical conductivity (approximately Brass, titanium, and PEEK) at an ambient temperature of 37.7 million Siemens per meter. Additionally, it is less expensive to produce and ship because to its lighter weight and ease of machining.


Aluminum is less expensive without considerably losing performance as compared to other machining materials (such PEEK, brass, and titanium). Additionally, due to its light weight and simplicity in machining, it has cheaper production and shipping expenses.

How to Prevent Distortion in CNC Aluminum Machining?

Although an indispensable industrial material, aluminum has a significant flaw. The alloys can distort when being machined into a thin part since they have a high thermal expansion and relatively low toughness. To prevent the material from being deformed beforehand, a few actions can be performed.

Symmetry in Cutting

In order to slow down the rate of thermal deformation, high heat concentration must be avoided and replaced with heat dispersion.

Multiple Stratified Machining

Due to the stress distribution, if an aluminum alloy plate has multiple cavities, one cavity wall can be readily twisted. You should fill all of the cavities at once to prevent this from happening.

Obtain the Necessary Cutting Parameter

The quantity of cutting-back depth has a major impact on the cutting parameter. To keep productivity high while minimizing the number of cuts. By speeding up the machine and lessening the cutting force, CNC milling can solve the issue.

Using a Drill and a Mill

The cutting is adequate when using a milling cutter on a cavity or piece. Heat, expansion, and deformation are caused by the. Pre-drilling with a tool larger than the milling cutter, followed by milling, is the best method for preventing this issue.

Final Thoughts

The numerous CNC machined aluminum processes (milling, drilling, and turning) that an unfinished piece of aluminum is put through until it becomes a finished product have now been explained to you. It takes a lot of time and calls for accuracy, knowledge, and dependable tools.
