CNC machining is a precision manufacturing technique. It is a complex process that requires a lot of training and expertise to accomplish. It also requires specific cnc machining parts. This is why industries depending on CNC technology for manufacturing often outsource their needs to professionals. When choosing the ideal CNC machining expert, some factors to consider are; the company’s experience, expert team, quality, reviews, and costs. The turnaround is also worth considering, especially if you plan to assemble the parts or use them for a larger project. This blog discusses the top CNC machining materials.
Common CNC machining materials
One of the best things about CNC machining is that you can apply various types of materials. Below are some of the most commonly used materials in CNC machining;
Metals
Various metals are used in CNC machining. The most common ones are;
1. Aluminum
Aluminum is one of the strongest, most durable, and aesthetically appealing materials in the manufacturing world. It features some of the best aspects and mechanical characteristics. The strength and durability of aluminum can be attributed to its oxide layer. The aluminum oxide layer develops when the metal is exposed to air and goes through oxidation. Aluminum is used to make automotive, aerospace, medical, and electronics sectors. These are sectors where CNC machining is highly applied.
2. Steel
There are various forms of steel used in CNC machining. Alloy steel is used for making parts that need stronger welds and advanced formability. Products made from steel are typically more robust, heat treatable, and formable. CNC machined parts from steel alloy are commonly applied in the automotive and aerospace industry. Note that there are multiple forms of steel alloys.
Another form of steel used in CNC machining is low-carbon steel. This metal is easy to manipulate and machine. It requires high strength and is magnetic. Its magnetic properties make it great for manufacturing studs and various small parts that need high-stress applications and strong welds. However, its magnetism also makes it highly prone to rust from exposure to different environmental conditions.
Finally, there is stainless steel. It is the go-to metal for making products used in various industries, like health, aerospace, automotive, and household product. CNC machining is used to make stainless steel products because it demands more formability. It is also a strong metal. Regardless, stainless steel is corrosion and rust-resistant.
3. Brass
This metal is commonly used for making medical and electrical equipment. It is also used to make musical, plumbing, and engineering products. Brass is an attractive, robust, and cost-efficient machine.
Others;
- Titanium
- Coper
4. Plastic
Various forms of plastic are also used in CNC machining. However, not all synthetic plastics are suitable for CNC machining. Below are standard qualities of plastic CNC machining materials;
- Strength
- Formability
- Weight-resistance
- Level of endurance
- Wear-resistance
- Aesthetics
- Applicability in various industries
Conclusion
The materials used in CNC machining may differ depending on the application area and the variety of products. For instance, Titanium and Aluminum are commonly used for CNC machining in aerospace. The form of the CNC machining process also influences the materials applied.
