Manufacturing the best wheels in the industry begins with nothing but the finest raw materials, made in California. Vossen Forged wheels are made of aerospace-grade 6061-T6 aluminum forged into a proprietary forging design. Heat-treated for additional integrity, these monoblock forgings yield quality equal to and sometimes greater than the raw materials used by the world’s top OEM automakers.
Once engineered, each wheel’s CAD model is programmed for machining using computer-aided manufacturing software (CAM). The program, or G-Code, is developed using CAM to guide each machine’s tool paths while ensuring that the final wheel precisely matches what the engineered CAD model intended.
The second step in manufacturing a forged wheel is lathe turning. The raw forging is lathe-turned inside, then flipped 180-degrees and turned outside, creating the rough profile of the final wheel. In this step over 70% of the original material is removed.
In this phase of production the wheel’s design is revealed while the CNC machines remove as little as 0.02'' of material per pass to achieve the utmost precision. An array of exclusive and intricate milled features characterize the Precision Series, while other Vossen Forged series have similar details echoed throughout.
Once the face design is complete, the wheel is rotated 180-degrees for additional milling. The lightening pockets are milled into the back pad of the wheel, shaving weight wherever possible.
The specifications of each wheel, such as serial number, vehicle application, size, offset, and load rating, are engraved on the inboard lip, marking each new wheel as a genuine and individualized Vossen Forged product.
The last step of the machining process is the final inner and outer lathe turning, the most critical in achieving the highest overall precision. The wheel is centered within 0.001'' of its spindle axis and all remaining excess material is removed. The final runout of the wheel after lathing will be less than 0.01'' and the wheel’s roundness is within the thickness of three sheets of paper overall.
Precision requires consistency and consistency requires control, which is why Vossen meticulously inspects every wheel during every step of the process. Vossen machinists conduct inspections on every wheel to ensure precision before proceeding to the next step. The quality control team confirms every critical dimension according to detailed engineering schematics. Runout, a measurement of a rotating wheel’s roundness, is the most critical measurement. Vossen Forged wheels are checked to confirm that the runout is within tolerance.
Vossen’s in-house finishing facility utilizes state-of-the-art equipment to produce only the highest quality finishes. From ceramic polishing to powder coating, all Vossen Forged wheels maintain industry-leading quality by monitoring every step of the process with the utmost scrutiny.
