Aluminum Machining

Aluminum is one of the most popular machining materials thanks to its workability, strength and versatility, while its low cost makes it perfect for prototypes and productions. From standard grades like 6061 to high-quality aerospace grades like 7075, we have an aluminum alloy for every aluminum CNC machining project.

We also have the skills and the equipment to handle it. Our team has years of experience in aluminum machining, (roughly estimated, around 70% of parts are in aluminum) and our in-house equipment includes HAAS 5-axis mills, Hexagon CMMs and Olympus XRF analyzers. We can guarantee the aluminum alloy is exactly material what you need for your project, as well as the tolerance.

Advantages of aluminum machining with 3ERP:

  • We are flexible from 1 off prototype to mass production
  • More than 40 machines allow us to make parts fast
  • We are able to make complex and tight tolerance aluminum parts

Getting a better price with 3ERP

Most CNC shops will only give quotations for CNC machining as a standalone process. But when the quantity of parts goes up to hundreds or more, you need a better solution. For some of these parts, it is better not to mill them from solid block at all.

When making aluminum parts, 3ERP offers several ways to combine CNC machining with other manufacturing processes in order to create more complex parts that can be made in large quantities. These process combinations can maximize the functionality of aluminum while reaping the benefits of other production processes.

Extrusion, casting and forging processes can all be complemented with CNC machining to make better aluminum components.

Here are some of the options we provide at 3ERP:

Die casting + CNC machining

Pressure die casting is a manufacturing process in which molten metal is forced into a mold cavity at high pressure. It is generally used when making parts in larger quantities, since the required tool steel dies are very expensive to make.

By die casting aluminum components then adding further cuts using a machining center, it is possible to create parts with an exceptional finish and more complex geometries than would be possible using either process on its own.

Die casting + CNC machining

Aluminum extrusion + CNC machining

Extrusion is the process of forcing molten material through an aperture in a die, producing an elongated component with a continuous profile. Because aluminum extrusion tends to involve malleable, ductile and machinable aluminum grades like 6061, the extruded parts can be cut in various ways using a CNC machine.

Combining aluminum extrusion and CNC machining is a great way to produce resilient parts with complex cross-sections and irregular geometries.

Aluminum extrusion + CNC machining

Forging + CNC machining

Many machinable aluminum alloys are suited to the age-old process of forging, which involves shaping metal through compressive force. (This often involves hitting the metal with a hammer.)

The forged pieces of aluminum can be post-machined with a CNC machining center, and this can be beneficial compared to machining alone, since forged parts are generally stronger than fully cast or fully machined equivalents.

Forging + CNC machining

Investment casting + CNC machining

Investment casting is a metal casting process that uses wax patterns to create metal parts. It produces parts with an excellent surface finish and high dimensional accuracy, and can be used to create intricate parts with no parting lines.

Aluminum alloys are a common material used for investment casting, and cast aluminum parts can be post-machined for refinement.
