How To Choose Your CNC Machining Aluminum ...

CNC machining is a combination of traditional and modern manufacturing techniques. This process uses a computer numerical control or CNC system to effortlessly cut and shape materials into objects. Without CNC machining, processing materials into intricately shaped and detailed components would be tough to achieve. Moreover, a CNC machine reaches an extremely high level of precision compared to manual labor, and it does this consistently and accurately, despite multiple repetitions of the process. Using Aluminum for CNC Machining Among all materials used for CNC machining, aluminum is among the best options. It is highly machinable, inexpensive, and three or four times faster to machine than steel or titanium. In addition, this material possesses excellent flexibility and an impressive strength-to-weight ratio, making it an ideal choice for making exterior skin panels for vehicles on land, air, and water. Other advantages of using aluminum for CNC machining include the following: Excellent corrosion resistance Outstanding electrical conductivity Resistance to low temperatures Great potential for surface finishing and anodization Recyclability What Types of Aluminum Are Used for CNC Machining? On its own, aluminum is too weak for commercial use. So, to achieve strength, pure molten aluminum is combined with copper, lithium, magnesium, manganese, silicon, and zinc to form an alloy and enhance aluminum's other properties. Three common alloys are used in aluminum CNC machining: cast aluminum, aluminum lithium, and wrought aluminum alloys. Cast Aluminum Alloy Cast aluminum alloys are affordable, lightweight, versatile, and durable and perform well under high temperatures. This alloy is famously used in the automotive industry for engine parts, housing, steering columns, and structural support. Cast aluminum alloys are inexpensive to produce because they possess a low melting point and can easily be shaped. However, it does have a lower tensile strength, is not as easy to machine, and is more hard-wearing on cutting tools. Aluminum Lithium Alloy The second aluminum alloy used for aluminum CNC machining is aluminum lithium alloy. This alloy is primarily used in aerospace manufacturing due to its lightweight nature, making it the prime choice for lower wing skins, inner wing structures, fuselages, and fan blades for aerial vehicles. Aluminum lithium alloys are also used for race cars and space rockets. The downside to using aluminum lithium alloys for CNC machining is it does not have a high fracture toughness. This means that when this alloy is cracked, it becomes compromised and weak to resist further cracking. Aluminum lithium alloys are also more expensive compared to cast aluminum alloys. Wrought Aluminum Alloy The last but best aluminum alloy for CNC machining is wrought aluminum. Wrought alloys have superior mechanical properties and structural integrity compared to cast aluminum alloys. They are also easier to machine and make for better surface finishes since they are less hard-wearing on the edges of cutting tools. Things To Consider When Choosing a CNC Machining Aluminum Manufacturer Getting acquainted with aluminum CNC machining is only one part of the equation; picking a suitable CNC machining aluminum manufacturer is the more crucial aspect. Choosing service providers for this task is not difficult. Here are four factors to look at when canvassing manufacturers. Long-Term Value Return When picking a CNC machining aluminum manufacturer, the cheapest option is not always the best. Instead, choose a service provider that offers excellent processing results and puts in the time and effort to coordinate with you to meet and surpass your expectations. This meticulousness will save you time and money, so always choose quality over plain affordability. Then, in the long run, you'll have a partner manufacturer you can rely on to consistently deliver outstanding results. Superior Machining Experience Experience should be factored in when deciding which manufacturer to choose; a long experience providing excellent service is how CNC machining aluminum manufacturers earn their stripes. In addition, the time they have spent in the industry can say a lot about their products. Usually, the longer a manufacturer spends engaged in the CNC machining industry, the more they can amass the necessary skills and experience to meet high standards. Reliable Team and Equipment Before partnering with a machining service provider, always check if they have the equipment and facility to do the job efficiently and deliver on time without sacrificing the quality of the finished products. A manufacturer offering machining services should not only have the necessary skills but should also have machines for milling, lathe grinding, and other processing methods. The best CNC machining aluminum manufacturer should have the proper equipment to handle complex projects. Proof of Quality Standards for Products When choosing a CNC machining aluminum manufacturer, you should pick one that can walk the talk. This means that manufacturers must ensure that the quality of the products they have created for you is up to your standards. A few more essential things to look out for when checking the manufacturer for their quality is if they have quality control methods, including product testing.

11 Questions to Ask a CNC Cutting Service Before Hiring

From the parts to construct a pop-up shop to a custom-built reception desk, CNC machining can create just about anything. As the go-to fabrication method for architects, designers, artists, and brands in creating decorative custom pieces for brand activations, exhibits, corporate interiors, sculpture, and art installations, there are a variety of CNC shops available to help bring a vision to life.

However, all CNC providers are not the same. With multiple areas of specialization, different CNC shops come with different equipment, material options, skill sets, and capabilities. Needless to say, it's important to match your project up with the right CNC shop.

CNC Cutting Services: 11 Important Questions To Ask

While commonly used for high-volume industrial manufacturing of metal parts, CNC machining can also be used for detailed woodwork and millwork. CNC machining continues to expand to other applications, giving brands the opportunity to construct a number of custom elements for corporate interiors, experiential brand activations, and much more. In this article, we'll help architects, designers, brands, and artists in their search by sharing important questions to ask and what answers to look for in a potential partner.

1. What is the typical turnaround for a CNC project like mine?

The timeline for a CNC machining project will depend on a few variables. However, when asking a studio this question, brands should be able to get a clear answer. Most shops can use their previous experience with a project type and articulate their process with well-defined steps.

2. What material would you recommend? Why?

While some CNC shops are limited to metals and wood, the most versatile CNC services will work with multiple materials. Not only will they have experience with metal, wood, and marble, but also plastics such as PVC, HDPE, UHMW, and ABS, composite materials, such as dibond, and both low density EPS and high density rigid Polyurethane foams. CNC shops should also be able to make recommendations based on cost, durability, quality of details, and other factors.

3. Can you source the recommended materials?

To prevent delays and changes to budgets, work with a CNC vendor that has access to the material specifications. If the vendor plans to source the materials, it's almost a guarantee that the timeline or budget will be challenged, at the very least.

4. Do you have experience cutting the recommended materials?

If the shop has experience cutting the recommended materials, ask for examples. It's important to know that the shop is capable of delivering a clean finish and detail fidelity. This will ensure that any custom office interior elements or brand activation displays are of the highest production value. Brands should also inquire about dimensional accuracy. If they do not have experience cutting the recommended materials, verify that parts can be cut with their equipment, and verify cut strategies with render clean finishes. Brands can also help develop a process for getting clean finishes to expectations on finish quality and production times.

5. What is the finish of the parts?

The finish of the parts will impact the quality of the final product. CNC shops should be able to confidently describe the quality of the finished cut. Professional shops should offer clean cuts and parts, or the services to clean them up if needed.

6. What is the largest part you can cut?

Larger cuts mean less seams and less waste, as well as a higher degree of dimensional accuracy. Professional scenic shops or design and fabrication companies should run a machine that can handle 4x8 or 5x10 sheet goods (the raw materials).

7. Can you pull cut profiles from a 2D drawing or 3D model?

Professional shops should be able to access information for CNC cuts from 3D files, interpret 2D drawings, and plan the right cuts accordingly. This is where experienced fabrication and design studios can be a great option, because while smaller shops and hobbyists may be able to do this in rare cases, it will be in a more limited scope. Many shops are only able to cut from the exact information that is given to them.

8. Do you do relief carving of 3D objects?

Deeper cuts for larger parts means less slices and pieces to reassemble. This is a more efficient process, and requires that studios have equipment built to cut deeper. Generally, this means that overall, brands have great dimensional accuracy and less labor to clean up seams. For brands, this translates into less waste and cost savings.

9. Do you have a 5th, 6th, or 7th axis on your CNC equipment?

This question applies to carving 3D shapes with advanced CNC equipment. In general, more axis means less undercuts and hand finishing. These multi axis machines excel in reducing machine setup times, considering the time to load the stock, position it, and secure it to the CNC table, because fewer cuts are required to achieve complex details. If the studio does not have a 5th, 6th or 7th axis, brands should ask how their process compensates for this.

10. Do you outsource?

Depending on their in-house capabilities, CNC machining shops may or may not need to outsource parts of their process. It's always important to know if shops do this, as it may add additional time and unnecessary cost to your project.

11. What other fabrication services do you offer?

Brands looking to hire a CNC cutting service can choose from a number of experienced shops. For complex projects, such as redesigning a corporate interior or launching a brand activation, however, a full-service design and fabrication studio is a one-stop shop. A full-service company will not only provide the complete scope of design and production services, but will also manage every detail from initial planning to final installation.
