Why aluminum is used in Bahagian pemesinan aluminium ?

Bahagian pemesinan aluminium has considered essential in advanced machining projects. Designers consider aluminum metal to be the best for CNC machining projects. Because it has lots of features.

It is one of the most powerful metals. And because of this feature designers consider it a complete metal in every respect for mechanical parts. Because this metal is highly resistant to corrosion.

Oleh itu, kerana ciri-cirinya yang tinggi, pengeluar menggunakannya di kebanyakan industri alat ganti. Bahagian aluminium kebanyakannya digunakan dalam industri berikut. Seperti:

• Aeroangkasa
• Automotif
• Penjagaan kesihatan
• Sfera elektronik pengguna, dll.

Pengilang menjelaskan bahawa aluminium umumnya milik bahagian Bahagian pemesinan aluminium . Ini pada dasarnya adalah bahan pemesinan terbaik. Kerana ia mempunyai kekuatan pemesinan terbaik jika dibandingkan dengan logam lain.

Oleh itu, ia menjadi bahan terbaik di industri pemesinan. Ia terdiri daripada ciri-ciri mekanikal dan termal yang hebat. Sebab di sebalik itu, bahawa aluminium  dianggap terbaik untuk membentuk.

Dan pengeluar menganggapnya sebagai logam terbaik berbanding yang berikut:

• magnesium
• titanium

Aluminium mempunyai beberapa lagi ciri. Seperti:

• Boleh dirawat
• Ringan
• Boleh dibeli
• 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 Bahagian pemesinan aluminium ? 

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.

Oleh itu, jurutera menggunakannya untuk pemesinan CNC 5 paksi. Ia mempunyai ciri mekanikal yang sangat baik bersama dengan kemampuan mengimpal yang hebat. Oleh itu, ciri-ciri tertinggi menjadikannya kelas aluminium terbaik untuk  Aluminum machining part.

• Aluminium 7075: Walaupun, ia tidak begitu biasa dibandingkan dengan 6061. tetapi terkenal dengan keletihan yang luar biasa. Pengilang merasa mahal. Oleh itu, ini adalah pilihan yang baik untuk mengikuti bahagian yang sukar:
• Bahagian basikal
• Fuselages
• Sayap kapal terbang
• Kit memanjat batu.

Gred ini juga luar biasa untuk ketahanan kakisan

Aluminium 2024 : Jurutera menggunakan gred jenis ini di sektor aero dan tentera. Kerana mempunyai ciri seperti:

• Kekuatan tinggi
• Rintangan keausan yang hebat

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 Bahagian pemesinan aluminium ?

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

And these are:

• Electrical conductivity
• Machinability
• Potensi anodisasi
• Strength-to-weight ratio
• Corrosion resistance
• Kitar semula

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. Aluminium 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

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

• Ringan
• High-strength.

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

• Automotif
• Aeroangkasa

Berbagai jenis gred aluminium mengendalikan pelbagai jenis bahagian mekanik. Aluminium 6061 gred banyak digunakan untuk bahagian umum. Sebaliknya, jurutera menggunakan gred aluminium berkekuatan tinggi 7075 dalam aplikasi laut dan aeroangkasa. Semua bergantung pada nisbah kekuatan-ke-berat.

Potensi anodisasi

Jurutera menggunakan Bahagian pemesinan aluminium  dalam industri elektronik pengguna. Mereka menggunakan bahagian mesin kerana sifat logam aluminium seperti kekuatan dan berat ringan. Aluminium boleh diproses dengan bantuan anodisasi.

Oleh kerana proses anodisasi berlaku setelah kerja pemesinan selesai. Selepas semua proses ini, sekeping bahagian aluminium telah dibuat yang tahan fizikal dan kakisan.

Kitar semula

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.

How can we avoid deformation in Aluminum machining part?

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 Aluminium 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 pemesinan aluminium .  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.

Kesimpulan: Bahagian pemesinan aluminium

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.
