CNC Machining of Precision Aluminum Parts with Lathe

Several processes are available for the production of aluminum parts, with the most popular one being the process of aluminum casting. During this process, molten metal is poured into a mold, die, or form to form a part. The aluminum forms a thin layer of aluminum oxide, providing a protective wall against corrosion. Typically, the parts are cast into a steel mold, which must be precision-machined to ensure smooth surfaces and a tight tolerance.

Many medical devices are made from cast aluminum, because of its strength and resistance to heat. Common medical equipment made from cast aluminum includes surgical tools, pumps, hospital beds, and components for monitors. Guns are another common application for die casting. Although many popular firearms are made of plastic, die-cast aluminum triggers and other parts are often used in the production of a firearm. For example, a gun’s cylinder, receiver, or barrel may be cast to produce a smooth surface.

Die-casting is a highly versatile process that produces parts with superior tolerances and surface finishes. This process allows manufacturers to make aluminum parts with minimal machining. Though die-cast aluminum parts have excellent surface finish, they can still have some rough spots on their surfaces. These can be addressed by sanding, orbital sanding, or sandblasting. The process also reduces machining time.
