We produce aluminum CNC turning parts for buyers in various industries around the world. This product showcases a CNC lathe-machined, anodized black aluminum knob with a knurled surface. CNC machined parts are the appearance, precision, size, etc. of the parts manufactured according to your drawings. Therefore, we can not only manufacture knob-type parts but also customize other non-standard metal parts. We can not only manufacture CNC aluminum parts but also parts in other materials, such as steel, brass, titanium, etc. We are a true source of CNC-turned parts, and our machines are capable of manufacturing any high-precision part. They run very fast, allowing us to deliver the part quantities you need in a timely manner to meet your production schedule. Our CNC turning centers support OEM production, laser engraving of your brand logo, optional finishes, and more. Our state-of-the-art CNC turning and milling equipment and experienced CNC operators are waiting for your call. Just send us your samples or CAD drawings and order delivery will be completed within 15 days. Contact us for free technical support.

Application of Aluminum CNC Turning Parts

The uses of a substance depend largely on its properties. Because aluminum has many excellent properties, aluminum has a wide range of uses. Aluminum and aluminum alloys are currently some of the most widely used and most economical CNC materials. The density of aluminum is very small, only 2.7g/cm³. Although it is relatively soft, it can be made into various aluminum alloys, such as duralumin, super duralumin, rust-proof aluminum, cast aluminum, etc. The density of aluminum alloy is 2.63~2.85g/cm3, it has high strength (σb is 110~650MPa), the specific strength is close to high alloy steel, the specific stiffness exceeds steel, it has good casting performance and plastic processing performance, and good electrical conductivity, Thermal conductivity, good corrosion resistance, and weldability. Through CNC turning or milling, these aluminum alloys are turned into special-purpose parts that can be widely used in manufacturing industries such as aircraft, automobiles, trains, and ships. Duralumin can be used to manufacture rivets, aircraft propellers, and high-strength parts on aircraft depending on the content of its alloy elements; super-duralumin is duralumin containing zinc, and its hardness and strength are higher than duralumin. Different varieties of superduralumin It is used to manufacture various structural parts and high-load parts, and is one of the important materials in the aviation industry.
