There are many kinds of aluminum material could be machined, such as AL5083, AL6061, AL6063, AL6082, AL7075, AL-MIC6, but the most commonly used Aluminum for CNC machining is briefly discussed as follows:

●6061

6061 is the most widely used Aluminum grade globally. Whether it’s the aluminum angle, aluminum bar, or aluminum plate, 6061 is a prime choice for furniture, boats, and many other structural applications.

Technically, the basic alloying element in 6061 is silicon and magnesium, making it amazingly resistant to cracking, stress, and corrosion. It also shows good weldability and formability.

● 7075

7075 Aluminum alloy consists of zinc as a primary alloying element with great mechanical properties, good flexibility, toughness, high strength, and resistance to fatigue resistance. Typically, the alloy is useful for highly stressed structural applications.

This aluminum alloy is often helpful in producing parts in the transport industry due to its high strength, including in aviation, automotive, and marine. Plus, they are used for manufacturing bicycle parts, climbing equipment, and hang glider airframes.

Currently, numerous methods can be used for the machining of aluminum, we review your project basd on the complexity and manufacturablility of the part, and we will evaluate the machining cost, the most popular CNC machining aluminum processes we offer are:

CNC milling methods are commonly used for Aluminum parts due to their numerous benefits. Such operations involve the movement of the cutting tool along the axis while the workpiece remains stationary.

Subsequently, the cutting action and material removal are done by feed motion of either the cutting tool, workpiece, or both.

In the CNC Turning of Aluminum process, the cutting tool remains stationary while the workpiece is rotated along its axis. Depending on the situation and conditions, the cutting tool or workpiece carries out the feed motion for material removal.

Wire Cut is a modern cutting process, using a wire to discharge electrical current and transmit them to the conductive workpiece.

Generally, the process is useful when the workpiece is smooth, uninterrupted, and even formed. Moreover, it is also useful when looking for high product precision and accuracy.

Primarily, EDM is a traditional method. It can create several Aluminum blind shapes and surface curvatures. It sinks in-depth into the Aluminum workpiece and cuts and shapes it accordingly.

Technically, the process is beneficial with the conductive materials because it exerts minimal force, making it effective for even fragile shapes.

Typically, the cost of CNC machining for aluminum is material cost + machining cost + surface finish cost.  We offer to our customers is 12 USD per hour for 3-axis CNC machining and 15 USD per hour for 4-axis CNC machining. You can prefer any method depending on your budget and the nature of the parts to be machined.
