Aprenda Usinagem de Ligas de Alumínio

Por que o alumínio é usado na Peça de usinagem de alumínio ?

Peça de usinagem de alumínio  tem sido considerada essencial em projetos de usinagem avançada. Os projetistas consideram o alumínio metálico como o melhor para projetos de usinagem CNC. Porque tem muitos recursos.

É um dos metais mais poderosos. E por causa dessa característica, os projetistas o consideram um metal completo em todos os aspectos das peças mecânicas. Porque este metal é altamente resistente à corrosão.

So, due to its high features, manufacturers are using it in most machining parts industries. Aluminum parts have mostly used in the following industries. Such as:

• Aerospace
• Automotivo
• Healthcare
• Consumer electronics spheres, etc.

Manufacturers explain that aluminum generally belongs to the Peça de usinagem de alumínio. It is basically a best machining material. Because it has best machining power in comparison to any other metal.

So, it has preferred as a best material in the most machining industries. It consists of great features of mechanical and thermal. The reason behind it is, that alumínio has considered best for shaping.

And manufacturers regards it one of the best metal in comparison to the following:

• magnesium
• titanium

Aluminum has some more features. Like:

• Tractable
• Lightweight
• Malleable
• Soft
• And a durable metal.

Hence, the color of this metal is dull grey and silver. But its color totally depends on its roughness quality. This metal is non-flammable.

How many types of grades of aluminum that engineers use in Peça de usinagem de alumínio ? 

The type of aluminum grade totally relies upon the aluminum machining part. Each grade has its specific value and different features. By knowing the properties of different grades, engineers will be able to choose the aluminum grade of their desire.

Here we are providing you information about some types of aluminum grades with extra properties.

Aluminum 6061: It has following excellent features like:

• Medium and high strength
• Superb corrosion resistance on severe condition
• Good toughness
• Cold anodization
• Great bending feasibility.

Conseqüentemente, os engenheiros o usam para usinagem CNC de 5 eixos. Possui excelentes características mecânicas juntamente com grande capacidade de soldagem. Portanto, essas características supremas o tornam a melhor classe de alumínio para  Aluminum machining part.

• Alumínio 7075: embora não seja tão familiar em comparação com 6061. mas é famoso por seu extraordinário poder de fadiga. Os fabricantes acham que é caro. Portanto, é uma boa escolha para seguir as partes difíceis:
• Partes da bicicleta
• Fuselagens
• Asas de aeronaves
• Kits de escalada em rocha.

Este grau também é notável pela resistência à corrosão

Alumínio 2024 : Engenheiros fazem uso deste tipo de grade no setor aeronáutico e militar. Porque tem recursos como:

• Força elevada
• Grande resistência ao desgaste

So, it is also reliable grade in Aluminum Machining part. But this grade is poor resistance of corrosion and it is not capable of being welded.

What are main advantages of Peça de usinagem de alumínio ?

In this article we are explaining major advantages of aluminum CNC machining parts.

And these are:

• Electrical conductivity
• Machinability
• Anodization potential
• Strength-to-weight ratio
• Corrosion resistance
• Recyclability

Moreover, here is a detail description of each of above properties.

Electrical conductivity

Because the aluminum metal has the best electrical conductivity, so they are also very useful in electrical parts. But it is not good conductor in comparison to copper. Although pure aluminum has about 37.7 million siemens per meter conductivity. But it has more conductive power than stain.

Machinability

The basic reason, for which engineers use it, is because it is very easy to shape in machines. Furthermore, its benefits are significant also from the maker to the end user. It is very easy to cut it with the help of CNC machine tools.

And it can be cut accurately and more quickly because of its aluminum quality. Alumínio machining part takes less time in machining job. So, its procedure has the following properties:

1. Extra cheaper
2. Need less time of operating

• Need less effort

Some more details are given below

Corrosion resistance

Different grades of aluminum have different endurance against corrosion. And luckily engineers use most durable aluminum in CNC machining. Such as, manufacturers has mostly used aluminum grade of 6061 for its great resistant quality. Because, powerful aluminum has some elements of copper, so it is possible that powerful aluminum have less corrosion resistant.

Strength-to-weight ratio

Alumínio machining part has two most beneficial properties. Such as:

• Lightweight
• High-strength.

These two features make it most advantageous for vital parts used in the following industries. Like:

• Automotivo
• Aerospace

Different kinds of aluminum grades handle different kinds of mechanic parts. Aluminum of 6061 grades is widely used for general parts. On the other hand, engineers use high-power aluminum grades of 7075 in marine applications and aerospace. All depends on the strength-to-weight ratio.

Anodization potential

Engineers use Peça de usinagem de alumínio in the consumer electronics industry. They use machined parts due to the properties of aluminum metal such as strength and light weight. Aluminum can be processed with the help of anodization.

Since the anodization process takes place after the machining work is finished. After all this process a piece of aluminum part has created which is physically and corrosion resistant.

Recyclability

Another great advantage of aluminum is that you can recycle it. This is extremely beneficial for engineers who want to reduce environmental pollution. And they want to earn something more than their expenditure.

So, in CNC machining a large amount of waste is generated while making chips out of the cutting tool. That can be processed later for many other uses.

Como podemos evitar a deformação em peças de usinagem de Alumínio?

As we know that aluminum is very important and basic industrial material. But it has a significant downfall. Because it has a high thermal expansion and has comparatively less hardness. So, it can cause deformation when manufacturers use it in machining thin part.

Furthermore, by taking various steps we can secure from deformation of these aluminum parts. And these useful steps are:

1. Stratified multiple machining
2. Symmetrical machining

Stratified multiple machining

If some aluminum plate consists of many cavities on its surface. Then engineers have the ability of twisting this cavity with the help of force destruction.

But you have to process on all cavities in one time period. Hence, you can easily get rid of these problems of Alumínio machining part with the help of Stratified multiple machining.

Symmetrical machining

For the good aluminum parts engineers should have to create dissolution of heat. In this way they can reduce the high rate of thermal deformation. Because it is very necessary to avoid severe concentration of heat.

How can engineers get an Appropriate Cutting Parameter?

Engineers believe that by using good machines, we can get the best machining parts. And with good cutting depth we can achieve this goal.

CNC milling can serve this purpose. Because it has the ability to increase speed and reduce cutting power in order to gets best Aluminum machining parts.

Moreover, by using these techniques you can get good cutting parameter.

Such as:

• Milling and Drilling
• Axis CNC Machining

Here we are providing detail about these techniques.

Milling and Drilling

In the procedure of milling, as engineers apply milling cutter to parts and cavity, it can cause heat, deformation and expansion. In order to avoid this problem, engineers prefer that process of drilling should be first. And then milling cutter should use for mill.

Axis CNC Machining

This process is rapid and safe for the purpose of designing complex sectors. It provides best aluminum machining part.  Because it can work in multiple directions. In this process, 5-axis machine has the ability to cut in five angles at the same time.

Conclusão: Peça de usinagem de alumínio

It is quite obvious that aluminum has many benefits like:

• The best quality
• Fantastic cutting process

The demands for aluminum machining parts are increasing rapidly. Many industrials are working on these projects in order to meet your needs. But research should be your first priority for best quality aluminum machining parts.
