Precision aerospace processing! CNC machining application!

Why the aviation industry needs CNC

Aerospace manufacturerUse CNC machining to assemble and maintain necessary aircraft and space shuttle components. Since a single defect or failure can cause catastrophic consequences in aerospace applications, OEMs in this industry rely on CNC machining to eliminate the risk of human error while manufacturing high-precision parts within tight deadlines.

CNC machinery can even be operated with the highest-quality metals to create parts that can withstand the intense pressures and temperatures inherent in aerospace applications. We at Ardel Engineering are well aware of the many benefits that CNC machining brings to the field of aerospace manufacturing, which is why we take this manufacturing technology as the core of the production process.

Our aerospace machinery workshop uses the most precise and latest technology to manufacture top-notch parts in the aerospace field. We work in a strict climate control environment and manufacture products with strict tolerances. We strive to anticipate and overcome any challenges that our components may face in the field.


Aerospace partsmaterial

Aerospace machining is different from the typical CNC machining process because it requires all metals to have incredibly tight tolerances without sacrificing their ability to withstand flight requirements. The materials used in aerospace projects must be lightweight, durable, and resistant to high temperatures.

Our aerospace machinery workshop uses the latest equipment to process aluminum and stainless steel, the two most commonly used metals in the aerospace industry.

  • aluminum:A lightweight metal with excellent ductility during processing and excellent durability after processing. Due to its corrosion resistance and high electrical conductivity, it is very suitable for a variety of aerospace applications.
  • Stainless steel:It has corrosion resistance and can withstand strong impact and normal wear. It can also withstand scratches, extreme temperatures and low pressure.

In addition to aluminum and stainless steel, we also deal with metals including inconel, titanium and high-stress alloys.

CNC medical processing requirements
In addition to meeting standards and obtaining certification, CNC machines must take other measures to successfully process medical components. After all, human life may depend on the success or failure of these machine components. According to accuracy, speed and material versatility, CNC processing is a very important manufacturing process in the medical industry.

Many medical parts are manufactured by professional medical manufacturers. These manufacturers must be able to manufacture highly resistant parts and may focus on biosailable and bio-compatible materials, and more importantly, they must be able to manufacture parts that meet international and government standards, such as those set by the U.S. Food and Drug Administration (FDA) for 4- and 5-axis processing of complex geometry, requiring CNC precision processing, all machine processing can be shipped using medical grade materials, and requires ultra-high cleanliness and safe packaging to deliver to customers.



Manufacturing mechanical parts in the medical industry is not like consumer electronics parts. While most common metal parts must meet ISO 9001 quality management requirements, medical parts must meet a further standard, ISO 13485, which is recognized by relevant regulatory bodies such as the FDA.
The Company’s requirements for CNC medical processing:
Precisely machined outer diameter Diameter: ∮ 1 mm to ∮300 mm
Process length Length: 0.5 mm to 1000 mm
Main turning materials: stainless steel, titanium, medical grade plastics
Tolerance: 0.01 mm

What is metal stamping service

Metal stamping is the process of putting flat metal in the form of blanks or coils into a stamping machine. In the press, the surface of the tool and die will appear as a mesh made of metal. Metal stamping includes various sheet metal forming manufacturing processes, such as punching, blanking, embossing, bending, flanging and embossing using machine presses or punching machines. This can be a single-stage operation, where each stroke of the press produces the desired shape on the sheet metal part, or it can be done through a series of stages.

The application of surgical screws will become more and more widespread!

When it comes to the cost of CNC machining, many factors need to be considered. For example, in a previous blog post, we studied how part design affects CNC machining costs. Today, we will study how the choice of materials, especially the choice of metals, affects the processing price.
Metals suitable for CNC machining have different mechanical properties, such as strength, ductility, and corrosion resistance. These characteristics lead to a series of machinability factors, which means that certain materials (with good machinability) are easier to grind and machine than others.
Generally, the easier the material is to process, the cheaper it is to process. This is because highly machinable metals can be processed faster, thereby reducing CNC costs. However, the cost of raw materials must also be considered because it affects the total cost of machining.
At RapidDirect, we provide a comprehensive selection of metal materials for CNC machining, including many of the most popular CNC materials and more professional options. We have a wide range of available materials, you can conduct a comprehensive consultation here, covering a variety of applications. Below, we will introduce the most cost-effective metals on CNC machine tools.

Aluminum processing

Aluminum is available in many different alloys and is one of the most cost-effective metals in CNC machine tools. Due to its high machinability (which varies slightly depending on the alloy) and low raw material costs, there is no doubt that aluminum is one of the most popular metals in the field of CNC machining. Aluminum has a high weight-to-weight ratio, good corrosion resistance and temperature resistance, so it is widely used in aerospace, automotive, healthcare, consumer goods and other industries. At RapidDirect, we offer a series of aluminum alloys for CNC machining, including the popular Aluminium 6061-T6, Aluminium 7075-T6 and Aluminium 6082.


stainless steel

Stainless steel (also available in a variety of alloys) is a popular and versatile material for CNC machining applications. Although stainless steel is not as workable as aluminum, it does have a good ratio of workability and low raw material costs. Stainless steel has many characteristics-including high strength, chemical resistance and hardness-making it an ideal choice for the automotive, aerospace, food, marine, and healthcare industries. RapidDirect provides a variety of stainless steel alloys for CNC machining: 303 stainless steel, with good machinability, is an ideal choice for the production of accessories and fasteners; 304 stainless steel, usually used for cooking utensils and chemical processing equipment; 316 stainless steel, suitable for more Extreme applications, such as applications in the marine or chemical industry. Of the three, 303 stainless steel is the most cost-effective choice due to the presence of sulfur and phosphorus.


Brass Brass is a metal alloy composed of copper and zinc, which ranks second in the list of cost-effective CNC machining metals. Brass has high machinability (better than stainless steel), although its raw material cost is slightly higher. However, the recycling rate of brass waste is very high, which can reduce the cost of raw materials. RapidDirect offers two brass alloys: Brass C360 and Brass C260, which have a high zinc content. Brass C360 is the most cost-effective option for brass processing because of its softness, ease of processing and low impact on processing tools. Generally, brass is known for its moderate hardness and high tensile strength, making it suitable for use in electrical products, consumer products, construction, automobiles, and healthcare.


Copper is similar to brass. Copper has high machinability, which means that the metal itself is not expensive for CNC machine tools. However, it is the price of raw materials that drives up the cost of copper. Nevertheless, copper still needs a popular material with good electrical and thermal conductivity, and is sought after in the automotive, consumer electronics, and healthcare fields. Other material properties include good corrosion resistance. RapidDirect provides two copper alloys for CNC machining: 110 copper, which has excellent electrical conductivity and formability; 101 copper, which has the highest copper content of all Cu alloys, so it has the best electrical conductivity.


Titanium is the more expensive end of CNC machining metal. Titanium is extremely challenging in machining due to its low thermal conductivity and high strength. In addition, raw materials have relatively high prices, which results in high material and processing costs. Nevertheless, the unique properties of titanium alloys (including excellent strength-to-weight ratio) make it a popular material in professional industries such as aerospace and medical. Titanium also has excellent corrosion resistance, chemical resistance and high temperature resistance. RapidDirect customers who want to use titanium can choose from two machinable alloys: grade 2 titanium with high corrosion resistance and the strongest grade 5 titanium (Ti6Al4V).

No matter when and where, our daily lives are inseparable from screws. These seemingly inconspicuous tiny tools can hold our electronic devices together to be able to hold buildings together. But are you aware that they can actually be used in your body? Sometimes, when a patient must undergo foot or ankle surgery, the surgeon will insert surgical screws or implants into their body to ensure that everything heals properly and stays together. This is just one way that surgical screws can be used in the human body. There are many problems surrounding these surgical screws and implants. Let us introduce you one by one.

What is Surgical implants?

Implants are objects placed in or inside the body for medical or cosmetic purposes. The screws used in surgery are specifically used to hold bones together to strengthen ligaments and tendons. They can also be used to attach tendons and ligaments to bones, or when the bones need to be completely replaced. Likewise, they can be used to hold dental implants in place.

What is the implant made of?

If you are about to have foot or ankle surgery, your surgeon may provide you with two main types of implants. These implants are divided into biological and non-biological categories. Biological implants are made of a material that will become scars and disappear over time. They are mainly used to strengthen or replace damaged tissues. Non-biological screw implants are made of metallic materials (such as titanium). These implants will not decompose over time and are permanently placed in the body.

Whether the implant needs to be removed?

Since biological implants tend to dissolve, one wonders whether non-biological implants need to be removed over time. The answer is no. The tiny screws or tiny screws placed in your body will not rust, move or harm your system. There are almost no consequences in your body. If you go to the airport, they won’t even detonate metal detectors, because they are small and need a lot to attract attention. Even if they do not need to be removed, your doctor may recommend removing them after everything is cured.

How to delete them?

If you and your doctor decide to remove the screw, first make an incision where the scar was left. However, it is important to note that the new cut will not be larger than the first cut. Then, the surgeon will enter the tissue and find the hardware. Upon arrival, remove it and close the incision. Screws can be used for many things in the family and daily life. In 2017, revenue from screw, nut and bolt manufacturing in the United States reached 30 billion U.S. dollars. Although they can be seen everywhere in our daily lives, it is worth noting that they can also be used in the human body.
