Production MethodAluminum Machined Forging

Machining of aluminum produces a beautiful finish.
Aluminum machined forging is a production method which utilizes a computer-controlled, high-precision engineering device called a machining center. A forged aluminum alloy billet is chiseled down like a sculpture and finished into a single aluminum wheel. Forged wheels cut and milled using a machining center can be finished into more lightweight wheels, with higher rigidity and a sharper appearance than wheels produced by forging alone. In comparison with design die casting, machined forging offers greater freedom of shape formation, and can be used to produce more complex and uncompromising designs.

MaterialAluminum Alloy 6061-T6

The“11R”utilizes the 6061-T6 aluminum alloy, which is an ideal material for forged aluminum wheels. A cylindrical 6061-T6 alloy billet is compressed using a 10,000 ton high-pressure forging press. The forging process alters the crystalline grain structure of the metal billet to follow the form of the wheel. Internal defects such as voids and air bubbles are pressed out, resulting in a greater level of toughness, and producing a material that is thin yet strong.

Cut 6061-T6 aluminum alloy billet

The aluminum alloy is compressed using a high-pressure forging press. During the forging process, the internal grain structure of the metal is finely deformed to produce a material that maintains a high level of strength, even when thinly shaped.

The forged wheel is cut and milled using an ultra-hard drill bit, made possible by the use of a high-precision machining center, which enables an uncompromis- ing design to be achieved.
