CNC turning remains one of the most versatile machines because of its ability to work with different materials. Engineers have different options when creating prototype products from raw materials to finished parts.
Though CNC turning uses different materials, it is essential to know the types of materials you can use in CNC turning to avoid damage to your machine. Read on as we take you through the types of material you can use.
We have two major types of materials for CNC turning. They are metal and plastic. Some of the examples are:
Aluminum 6061 is one of the most common metals suitable for general-purpose CNC machining. The major alloying components of aluminum 6061 are silicon, magnesium, and iron. It has a good strength-to-weight ratio, resistant to corrosion, and has good CNC machinability.
It is used for sporting goods, frames for RC vehicles, auto parts, and some aircraft parts. However, it has low resistance to corrosion from salt water or chemicals.
Brass is another metal material type that is suitable for CNC turning. It is an alloy of zinc and copper. The softness of the material enables it to be used on the machine without any form of lubrication before use.
Brass works very well at room temperature. Thus, brass does not need great strength. We have different forms of brass materials based on the percentage of zinc. The more the percentage increases, the less its corrosion resistance. It is used for musical instruments, home hardware, naval hardware, zippers, etc.
Generally, stainless steel is a good metal material suitable for CNC turning. We have different types. Stainless steel 304, is found in different variety of industrial and consumer products. It contains an extra 8% nickel and 18% chromium in the alloy. The additional elements make it non-magnetic and tough.
Titanium is known for its toughness, high strength, corrosion resistance, and lightweightness. Titanium is a good conductor of heat but a poor conductor of electricity. The material can be passivated, welded, and anodized for increased protection.
ABS is a plastic CNC turning material that is good for different projects. It is tough, chemical-resistant, electrical current-resistant, and impact-resistant. Due to it strong, stable, and great finishing, it is excellent for fast prototypes.
ABS is easy to color and has a wide range of uses. It is not expensive and can be used for power tools, automotive components, toys, and other applications. However, it does not withstand very high temperatures for a long time.
We have various features in Nylon that are similar to that of ABS. In addition, nylon has greater tensile strength. A mixture of nylon with ABS and glass fibers can produce a high-quality property for mechanical parts. However, nylon can absorb moisture after long exposure, which makes it unsuitable for marine use.
Investing in a quality machine is key to the successful execution of projects. Are you looking for a reputable manufacturer of quality CNC machines? We are here to guide you.
