The Properties of Aluminum Alloys
Aluminum is a comparatively new industrial metal material that has been manufactured in commercial quantities for almost 100 years .On application of industry ,exactly say it is aluminum alloy ,rather than the pure aluminum ,such as: Aluminum 6061 ,Aluminum 7075 etc .Today aluminum alloy materials have been widely used in many fields and can be seen almost everywhere in people lives. It has become ideal material for many industry applications because of it’s excellent mechanical properties ,high strength ,lower corrosion resistance, good machinability ,good weldabily ,workability ,including it can be anodized.
The Problem and Solutions of Aluminum Machining
This metal has many advantages. However，Aluminum has two key problems that may be encountered during processing. This is the high viscosity of the material and its tendency to stick. These characteristics must be considered when selecting machining tools and cutting conditions.
Lots of Shavings
Due to its toughness, aluminum tends to form a lot of chips during milling. In this case, the chips become long and sticky, are poorly discharged, block the grooves of the cutting tool and become entangled on the cutting tool. Then the machine did not cut, but crushed the metal. This is particularly important on CNC machines. The machine stops cutting within a few minutes due to the aluminum shavings entangled on the cutting tool. This causes the cutting tool to overheat and often even fail.
Edge Accumulation
There is another disadvantage when milling aluminum. This is a deposit formed on the cutting edge of the tool. This surface hardening can cause the cutter to overheat and unbalance, which can cause the machine to jam and damage the machine. If the correct choice of cutting tools can solve the problem of aluminum chips blocking the grooves, then the problem of covering aluminum on the cutting tool can only be solved by increasing the cutting speed
Solutions
- Taking special measures to eliminate negative effects. In particular, the cutting edge on the blade should be as sharp as possible. Coolant must be used to better evacuate chips.
- For machining high-strength aluminum alloys, such as: 7075, 6082, it is best to use diamond-coated blades.
- If a more efficient operating mode is installed, negative effects can be avoided. Low cutting speed will only exacerbate the problem.
- If possible, choose the smoothest cutting tool designed for machining aluminum alloys.

Aluminum is a standard material option for CNC machining projects due to its desirable physical properties. It is strong, making it suitable for mechanical components, and its oxidized outer layer resists corrosion from the elements. These advantages have made aluminum parts popular in all industries, but they are prevalent in the automotive, aerospace, healthcare, and consumer electronics sectors.
Aluminum also has distinct advantages that simplify and strengthen the CNC machining process. Unlike many other metals with similar material properties, aluminum has outstanding machinability: it can effectively penetrate many of its grades by cutting equipment, chipping while remaining relatively easy to form. As a result, aluminum can get machined three times faster than iron or steel.
Mold makers also use aluminum designs. When the request is minimal and the mold’s lifespan is unimportant, producing an aluminum mold saves a lot of time than making a hardened steel mold. In addition, rather than the expensive method of making an injection mold, aluminum may get used for carbon fiber or thermoforming molds.
We Create CNC Machined Aluminum Prototypes by Industry Experts
Aluminum CNC prototyping is quite prevalent for approving the design and material characteristic test. It is suitable for new product design in most industries, no matter the future high volume production through by machining or casting, machine aluminum prototype is always a good option, high production efficiency, faster delivery time .
Aluminum gets used to machine a wide range of goods from several industries. Although many vertical industries use aluminum to produce unique products, the electronics industry is one of the most popular. The products manufactured include industrial control enclosures, heat sinks, frames, laptops or cellphone bodies, etc. Also, seemingly minor parts, such as volume buttons, are often made of aluminum to give the product a more premium feel than plastic.
Parts machined in aluminum are also used in the aerospace and defense industries, such as enclosures for radar boards and structural components. Furthermore, the automotive industry relies on aluminum machining to mass production of car parts such as panels, interior trim, and hardware.

Anodizing For Aluminum Machined Parts
Anodizing aluminum is a very long-lasting post-processing procedure. It improves the properties and appearance and allows for better adhesion of paint primers and glues. This method employs anodic films with distinct aesthetic effects, such as transparent coatings that reflect light or dense layers that can absorb dies.
Anodizing aluminum does not change the material’s natural appearance, despite affecting its mechanical capabilities. Although we can use the anodizing process on other metals such as titanium, copper, and magnesium, aluminum is the most commonly used.
Key Benefits of Anodizing Aluminum Parts
You may come into contact with anodized goods and parts regularly. The anodizing aluminum process gets widely used for various applications, including components found in aircraft, consumer products, sports equipment, and electronics, to name a few.
There are many advantages to anodizing aluminum pieces, both visually and mechanically. For instance, anodized aluminum pieces are extremely tough and durable. Because of its ability to increase abrasion and corrosion resistance, this method is suitable for components that will get used in harsh environments. It also provides excellent thermal insulation for metal components.
Anodized metal parts can last longer than raw metal parts. The coating layer is much thinner than paints and powders, but it also provides a much more robust surface. Another advantage of anodizing aluminum pieces is that they have an environmentally friendly finish that makes them easily recyclable. Perhaps most importantly, the post-processing procedure is less expensive than painting and powder coating.
The Importance Of EDM In Aluminum Parts Machining
EDM is a precision manufacturing process, which mainly uses a discharge electrode with a specific geometry to burn out the geometry of the electrode on a metal part .It continuously produces pulsed spark discharge between the tool and the work piece during processing.
The work piece material is eroded away by the local and instantaneous high temperature generated during the discharge. But in fact the tool electrode and the work piece are not in direct contact, however, there is a spark discharge gap, the gap is generally between 0.05-0.3mm, and sometimes it may reach 0.5mm or even bigger.
The gap is filled with working fluid, and the work piece is corroded by high-voltage pulse discharge during processing .It’s often used in Aluminum machining due to being able to manufacture the finest details and surface finish work, intricate cavities and shapes .For example ,for some of aluminum prototype parts ,the CNC cutter tool can not mill the sharp internal corners on the bottom because of the structure of object ,probably this is unacceptable for some designs if they are some crucial locations on fitting ,then ,It’s a good way to solve it with EDM.
