Aluminum machining service is getting widely popular nowadays. Because of aluminum’s high machinability and low-cost process, you can now have the best quality machined product at a lower price!

Although, finding the right manufacturer, communicating with them, and finally ordering your desired product is not a child’s game.

Many small variables can make a huge difference in your product’s design and quality. Before ordering, you need to know all the ins and outs of it.

This article aims to let you know what’s the most important things to know and consider before ordering an aluminum machining service from China.

What is CNC Aluminum Machining Service?

CNC or Computer Numerical Control machines that can manage tools around a different number of axes. With these machines, manufacturers can make a substantial part with the help of a computer design file.

CNC machining is a subtractive process, which extracts material from an aluminum piece and makes a shape out of it. These machines are dependent on the computer design and do exactly they’re instructed to. CNC machines are used in both prototyping and final production.


The primary benefit of the CNC machining is the accuracy and speed it has to offer. In the early stage of this machine, it used to rely on machinists to provide the instructions manually.

But as the technology grew, now it’s entirely dependent on computers and computer-based designs. Engineers use programs like CAM or CAD to provide the exact design and instructions to the machine. And the rest is done.

There are many different ways to remove the material from stock, using the CNC machines. Such as drilling, lathes, milling, turning, tapping, grinding, etc. The milling machine is similar to the drill method and the most popular among others.

Sunrise Metal has the capability to implement the methods that are compatible with your project.

Why You Should Choose Aluminum Machining Service?

If you’re looking for custom made or designed products, aluminum machining service is perfect. The high machinability of aluminum makes it easier and less costly compared to other materials.

Aluminum offers higher strength and corrosion resistance, making it the most popular choice for machining among the buyers in OEM/ODM industries because you’ll want something that will last a long time without being damaged.

And if you’re like most of us, you’ll want something light in weight and easier to work with. That is just what you can get in aluminum machining service.

Because of its lightweight feature, it helps you in two different ways. The first one is that transportation is less costly and more comfortable because of their strength.

Second is it saves a lot of fuel when used in cars, trucks, railways, and airplanes by adding less weight.

Aluminum machining

Using it for vehicles is a good idea for another reason. When an accident happens, the vehicle’s aluminum structure absorbs most of the impact or shock inflicted by the crash and secures the passenger.

The aircraft industry is heavily dependent on aluminum machining service for various reasons other than saving fuel. Aluminum helps the aircraft to be airproof, which makes the aircraft more comfortable and safe. And to be lightweight and fly fast.

Other than vehicles, aircraft, and ships, many industries get benefited from aluminum machining services, like construction, food processing, packaging, and so on.

How to Choose a Reliable Aluminum Machining Service Provider in China?

You probably already know how to find and choose reliable manufacturers in China. But let’s see a quick recap. And after that, you’ll find additional factors that you’ll need to consider while choosing the right aluminum machining service provider.

Like you know, first, you have to find and qualify the manufacturers and make a shortlist. Then verify them, see if they are legit or not. After you’re satisfied with their company and their presence, arrange a factory visit.

And the last part was the most important. Because a lot of people tend to avoid visiting the factory. If you don’t have the time or don’t want to do it yourself, you can always hire or send someone else.

You’re probably wondering why it’s the most important of so many. The reason is when you do factory visits; you get a clear idea of their production plant, workforce, current and previous work, past clients, and most importantly, their CNC machine.

Even if you can’t make a factory visit, know what type of CNC machine are they using. Because this can make all the difference. If a manufacturer uses low-quality machines with only limited capabilities, the final product won’t be right.

You’ll need to put more emphasis on the CNC machine your chosen manufacturer is using. If they’re using the latest technologies and skilled engineers for their production, you’re in good hands. And if not, then you need to choose a better alternative.

But keep in mind that no matter how reliable your chosen manufacturer is, always keep communication with them. Because in this way, you’ll get to know what’s happening with your order and when exactly you’ll be receiving it.

Which Aluminum Alloy is best for Aluminum Machining Service?

When it comes to alloys, there are plenty of options. And while machining, we need to choose the right alloys for specific projects. Workability and tolerance are different for each alloy. As a result, selecting an improper alloy for machining can make the process a lot harder and defective.

In general, Aluminum 6061 is the most popular choice of alloys for machining. It’s strength to weight ratio, corrosion-resistant and machinability make it more workable than others.

Although for specific projects, some other alloys provide the best results. For aerospace parts, Aluminum 7075 is widely used. However, as a general rule of thumb, Aluminum 6061 provides the best results among all.

Choosing the right alloy is critical in this process. Although aluminum is way more machinable than other products like titanium, steel, etc., there comes the point when you need to choose the right alloys.

Not all alloys perform the same in the different working process. Some are more heat resistant, while some hold more strength to them. You’ll need to choose them according to your requirement and machinability.

If you need aluminum alloys for welding Aluminum 1100 might be a better choice for you. Because of their high weldability, they make the perfect choice for welding needs. But you can’t choose them if you need strength.

Almost all the alloys have some capabilities in some processes and lack the ability in some. Depending on the requirement and process, you need to choose the right one.

There are some key points to consider while choosing the right alloy. First, if you need something with higher strength, heat and corrosion-resistant, you’ll get a shortlist of fine alloys that meet your criteria. Then you’ll need to find out your desired one by measuring their workability, machinability, and the overall use of end products.

Why CNC Aluminum Service is So Popular among Buyers?

CNC aluminum service is widely accepted and used in manufacturing method all around the world. Industries like marine, aerospace, automotive, medical, textile, telecommunication, dental, construction, and other industries rely heavily on CNC aluminum service.

The reason is obvious. CNC aluminum service can manufacture and produce highly accurate, top-notch products. It’s able to produce a bulk amount in less time. And on top of that, the lead time and cost per unit are significantly lower than other methods.

With the CNC aluminum method, the margin of error is next to zero. Industries like aerospace, marine, or telecommunication cannot afford to have errors or defects in their parts. They need something that is precise, accurate, and meets their requirements.


The aluminum alloys used in this process makes the final product heat and corrosion-resistant. It makes them usable for a longer period. Aluminum alloys also offer higher strength and great workability than other metal materials.

Because of the computer-operated system, the manufacturing process becomes fast, cost-effective, accurate, and repeatable. It also eliminates the chances of human error.

CNC machining can produce complex parts and products that’d be very hard with other manufacturing processes. Certain automotive, aerospace, or telecommunication parts are so complex to make that it’s nearly impossible to reach the accuracy without CNC machining.

In conventional machining, the chance of human error and wastage was significant. It also requires more human resources because every machine needs one machinist working all time. On the other hand, the CNC machine eliminates risks while enabling one engineer to simultaneously control multiple machines.

Most buyers, sourcing agents, OEM/ODM companies require ultra-precise parts with top-notch quality. CNC aluminum machining can meet this requirement with a large number of quantities and cost-effectiveness in mind.

For these reasons, CNC aluminum machining service is growing at a rapid pace. As a result, almost all industries around the globe are more and more dependent upon it.

What is the Cost of Custom CNC Aluminum Machining Service in ?

The cost of your custom CNC aluminum machining service depends on many variables. You might be searching the web for a solid answer, but got no result. Or asking manufacturers for quotes and still be confused.

Don’t worry. You’ll get a clear direction now.

The reason why you’re not getting the right answer is that you’re asking the wrong questions. Manufacturers can’t give you a proper quote unless they have your design and requirements. Let’s have a look at the factors that affect your cost.

Design: The cost of your machining service begins at the design stage. Although CNC aluminum machining requires little to no labors for operating, they still need a design engineer; Who will design and digitalize the design for the machine.

This part can add a lot of weight to your budget. While designing, make sure you’re not choosing a very complex design. The more complex and critical your design is, the higher your cost will be.

A complex design will cost more on designing and digitalizing. But on top of that, it costs way more on production. Because complex parts will take more time and raw materials to manufacture. Which will bump up the cost significantly?

Equipment: The tools that require for your project also plays a vital role in your budget. Manufacturers often charge customers by the hourly rate on their machines. The rate of the machines is different from one another based on their capabilities.

For example, 3-axis machines have a lower hourly rate than 7-axis machines. If you need a quotation for our pricing, please feel free to give us a knock.

Raw Material: Another important factor is your raw material. Different types of alloys are used for machining. But depending on your project, the cost of alloy can make a difference.

For instance, Aluminum 6061 is the standard alloy used for automotive, textile and other industries. This alloy costs less per block than other alloys like 7075—the weight is lower as well, so it also saves the shipping cost.

On the other hand, if you’re ordering CNC aluminum machining service for the aerospace industry, you’ll need Aluminum 7075. And this can be costly compared to the other one. Because this alloy costs more per block than others. Almost three times than Aluminum 6061. It also weighs more, so more cost on the shipping.

Finishing: Often you’ll need finishing for your products. You could avoid finishing for some of the products, but it’s better and often necessary to have a surface finishing. And that could cost you some additional money as well.

Shipping Cost: Shipping costs will largely depend on the weight of your products and the distance. You’ll want to have a fair amount of time to ship the goods to your location. Because emergency or fast shipping can cost you a large amount of money.

What Process Do They Use in Aluminum Machining Service?

There are different types of CNC machines to choose from. As the technology evolved, new methods were added to make this machine even more compatible. Some of them are:

drills for CNC aluminum service

Drills: Drills work by spinning the drill bits against the surface and subtracting materials by its rotation speed.

Turning: This might be the earliest process of CNC machines. The capability of turning has been increased significantly over the years. But still, it has limited applications compared to other processes like milling.

In this process, the workpiece is held by the machine against a drill bit. This process is more suitable for subtracting a large volume of material that does not need high precision.

milling for aluminum machining service

Milling: Unlike turning, in this process, the workpiece is held stationary. This CNC machine has a cutting tool that rotates on a spindle. The milling machine looks kind of like a drilling machine but works differently and a lot more advanced.

This is the most used machine in CNC machining and complex parts are usually machined with this process.

Grinding: This method is only used when a flat surface is required. In this method, the workpiece is mounted on a table and a spinning disk spins and cuts the work piece’s surface.

grinding for aluminum machining service

These are the most convenient ways of machining aluminum. Other than that, there are several different ways for machining for specific projects. Like Plasma cutting machine is used to machine steel materials. Electrical discharge machining is another process that is often used for cutting different kinds of complex holes and shapes into hardened steel material.

What is The Minimum Wall Thickness in Aluminum Machining Service?

Designers and engineers always try to push the limits of making the parts lighter, thinner and more versatile. But there’s always a limit. And if the limit exceeds the part’s quality will be jeopardized.

The wall thickness may be dependent upon the CNC machine itself. Depending on the capability and quality of the machine the wall can be made thinner than that. Also, lower-quality machines cannot make a wall as thinner as a high performance machine could.

What is the Difference between Steel Machining Service vs. Aluminum Machining Service?

Machinability is the first and most significant difference between these two materials. Aluminum has superior machinability and workability when it’s compared to iron or steel material. It can be machined and shaped easily with any CNC method. It chips easily and takes a shorter time to machine.

Compared to aluminum, steel machining can take up to 3x or 4x more time to complete the process. Because of their lack of machinability. Aluminum is easier to cut, which makes them faster to be machined and reducing the lead time.

Other setbacks of steel machining are that steel is heavier in weight and contains less thermal conductivity. In comparison, Aluminum having the highest thermal conductivity and less weight than steel or iron alloys.

Aluminum saves time and effort by being one of the most workable materials among them. It is way faster to machine and polish aluminum than to steel or iron. Besides having a lower melting point than steel or iron materials, you can use aluminum’s electrical discharge machining at a much higher rate than other materials like steel.

And because of these reasons, aluminum machining can be the most effective option for most cases. However, there are projects where steel machining is mandatory. In general, aluminum beats the other options.

What is the MOQ for Aluminum Machining Service?

There is no standard MOQ for Aluminum Machining Services in China. Different companies have different requirements for MOQ. Usually, bigger companies won’t be interested in low volume orders, and small companies can’t provide the aluminum machining service that you desire.

This is where Sunrise Metal can help you. Sunrise Metal is the leading company in China with state of the art machines and multiple production plants. We welcome low volume and high mix. No matter how low your volume is, we believe in quality, not numbers.

What are the Benefits of Aluminum Machining Service?

Aluminum is a widely used material for machining service. For almost any industry and parts, aluminum can be a great choice for machining. Let’s see some of the major benefits of aluminum machining service:

Machinability and workability:  Aluminum is a soft material by nature. As a result, it can be cut, shaped, and machined quite easily than other hard materials. It chips easily, making it easier to work for machining service. With aluminum, we can make more complex materials with less power. Which makes it even more suitable for any machining service.

Affordable and low cost: Aluminum is an affordable option when it comes to machining service. The price of aluminum alloys is way less than steel or iron alloys. Other than that being easier to the machine and requiring less power, aluminum can be machined with a meager cost compared to other materials.

Corrosion Resistant: Aluminum offers excellent corrosion resistance quality. However, the different aluminum alloys or grades have other corrosion resistance ability. The most used grade, Aluminum 6061, has an astonishing amount of corrosion-resistant quality.

Strength to weight ratio: Aluminum has an amazing strength to weight ratio compared to any other material. It is almost three times lighter than steel but has a fair amount of strength. As a result, the aerospace and automotive industry rely on this material heavily. Because they need the parts to be strong but lightweight, exactly like aluminum.

These play a major role in making aluminum favorite for machining service. Other than that, it has several more qualities that make it even more suitable. Electrical conductivity and recyclability are two more factors that also are responsible for making the aluminum best choice for machining service.

Why Should I Choose Sunrise Metal for Aluminum Machining Service?

Aluminum machining service is one of the manufacturing processes where you need to be the most careful while choosing the company. Because it requires extensive care, state of the art machines, a super-skilled workforce, a highly experienced quality control team, and strong leadership.

Because if your chosen company lack any one of those, your products will suffer and so will your company. Sunrise Metal, having 10+ years of experience in this field and serving 500+ global customers with 1000+ products, knows what you want.

Here, at Sunrise Metal, we understand what you require, and we work hard to make your vision come true. Many buyers, OEM/ODM companies, often need low volume or high mix productions. And we welcome them with wide hands.

What is the Standard Lead Time for Aluminum Machining Service?

Lead time can vary significantly from manufacturer to manufacturer. It also depends on the project itself to a large extent. But as a general rule of thumb, for a low or medium-size order, expect around 10+ days lead time.

faster lead time-sunrise metal advantage

If the manufacturer has a skilled workforce, fast quality control team, and a fair number of required machines, the lead time should be lower and vice versa.

It depends on your order as well. If your design is too complex, your project requires rare raw materials or complex parts to manufactured; it will take a longer time. Also, a large volume of orders can cause more lead time than low volume.

When you’re placing an order to any manufacturer, ensure that both of you’re clear and agreed upon the final goods’ delivery date.

What are Some Product Examples of Aluminum Machining Service?

Aluminum machined parts are now widely used throughout various industries. Some examples of them are given below:


  • Auto parts * Aircraft parts
  • Engine Parts * Lighting parts
  • Electrical equipment *Medical tools and devices
  • Kitchen tools *Door handles
  • Marine parts *Textile equipment and tools
  • Sanitary products *Hardware tools

Why Manufacturers Use Lubrication in Aluminum Machining Service?

Lubrication plays a significant role while machining aluminum. It helps to cool down the heat that is generated by the friction. It also helps the chips not to get attached to the tool and remove the chips from the point of friction.

Before choosing the lubricant, manufacturers need to ensure that they are compatible with the aluminum and don’t cause any corrosion. It should also be anti-bacterial and environment friendly.

Why Sunrise Metal Uses High-Speed Machining for Aluminum Machining Service?

As the name sounds, high-speed machining allows the spindle to remove the material at a higher speed than conventional machining. Being fast meaning more efficient production and less lead time. You might think the quality or finishing is poor in HSM. And you’d be wrong. High-speed machining can generate high precision results, because of their low pressure and higher vibration stability.

With HSM, the use of coolants is reduced. The reason is quite strange, although being faster should generate more heat, in that case, after a point, the temperature goes down as low as 200 degrees. Needing no extra coolants.

With high-speed machining, the tools also live longer. Because of the saved worked hours as a result of fast production. It also enable us to continue production at a much cheaper rate than conventional machining.

These are the primary reasons why Sunrise Metal uses the HSM strategy to machine your parts. We are committed towards higher accuracy, cost-effectiveness, and minimum lead time. With this strategy’s help, Sunrise Metal can achieve their goal and make the customers happy.

How to Increase the Efficiency in Aluminum Machining Service?

One of the significant ways of increasing efficiency is to adopt high-speed machining technology. This enables manufacturers to speed up manufacturing up to 3 times compared to the conventional machining method.

Having said that, there are many factors that need to be improved to increase efficiency. From the initial stage to the last stage, an efficient strategy should be implemented.

At Sunrise Metal, our goal is to provide the best quality product in a short period. So our customers don’t have to wait long for the products and can continue their project with the finished product. This is why lower lead time is our topmost priority.

We try to be as efficient as possible from the earliest stages. From the discussions to the design period to production, we have to be extra careful not to delay time unnecessarily.  Design is important, but you need to have a proper design and consulted with a professional designer and approved by our team of skilled designers.

Because a lot of the time, defective design can eat up a lot of the time if not addressed carefully at first. Another important factor is a complex design. If you have less time in hand, don’t choose a complex design and will require a longer time to machine.

Other than these technical factors, many things go with the management and leadership of a company. Companies like Sunrise Metal has years of experience and skilled technicians to make the process most efficient. An inexperienced or less capable company cannot provide you an efficient service up to your expectations.
