Aluminum is the most abundant metal element in the earth's crust. It has good ductility, flexibility, conductivity and durability, and its appearance is silver or dark gray. It is a commonly used machining material because of its excellent cutting performance. CNC machine tools can manufacture unique and quality aluminum prototypes. CNC milling is the perfect choice. Its advantage lies in the machining process, and that is the high precision of milling aluminum. Aluminum CNC milling is the application of a rotating tool that is professionally polished, removing it by advancing the tool to a workpiece. Complex parts with complex shapes can be serviced by aluminum CNC milling. Precision CNC machined aluminum parts include: front panels, pins, spline shafts, medical equipment, lighting devices and more.
The following knowledge points are listed below:

The cnc milling process for aluminum parts
Four benefits of cnc milling aluminum parts
Aluminum is the most widely distributed metal on the earth, accounting for more than 8% of the earth's core mass. It is also the third most common chemical element on earth, after oxygen and silicon. In 5300 BC, the Persians made very strong pots from clay containing alumina. The ancient Greeks and Romans used alum as an astringent and dyeing process in medicine. But aluminum is not naturally produced in its purest form. It was not until the 19th century that aluminum was discovered with the development of chemistry and the emergence of electricity. It is usually found in minerals and compounds such as feldspar, beryl, cryolite and turquoise. The main raw material for producing aluminum is bauxite. Bauxite is commonly found in the topsoil of various tropical and subtropical regions, with the largest reserves in Africa, Oceania and South America.
In the first stage of aluminum production, bauxite is processed into alumina, or alumina. Alumina looks like white powder and is processed into aluminum in an aluminum smelter using an electrolytic reduction process. The shape and size of aluminum ingots depend on their end use. They can be rolled into plates, sheets, foils, rods or rods. Now aluminum are commonly used in cnc machining parts.
Numerical control milling, or computer numerical control milling, is a processing process that uses a computer-controlled and rotated multi-point cutting tool to gradually remove material from the workpiece and produce custom-designed parts or products. This process is suitable for processing various materials, such as metal, plastic, glass and wood, and producing various custom-designed parts and products. In this article, we talk mainly on cnc milling parts with aluminum.
(1) Recyclability: A very important benefit of aluminum is its huge recycling potential. This is a good thing for companies that attach great importance to reducing their environmental footprint.
(2) Strength to weight ratio: As a material, aluminum has reached a very important point of perfection: it is both light and strong. This makes it not only highly maneuverable, but also will not break under high pressure during production or use. This makes it very suitable for key component manufacturing in key product industries, such as automotive, aerospace and heavy equipment component manufacturing.
(3) Corrosion resistance: As mentioned earlier, aluminum is a non-ferrous metal. This means it will not rust or corrode. 6061 is the most commonly used aluminum grade and the most corrosion resistant. This earns an extra durability point for the metal because it can better withstand various elements (in this case, moisture).
(4) High conductivity: Due to the conductivity of aluminum, as a metal, it is the best material for manufacturing electrical components. The conductivity of pure aluminum at room temperature is 37.7 million Siemens/meter (spr). This may make it lower than materials like copper, but it is still higher than other metals, such as stainless steel..
