The vast majority of aluminum alloy automobile wheels are now cast, despite the heat treatment, the residual stress must still exist. If it is an even number, it is easy to produce greater stress on a pair of spokes at 180 degrees, which exceeds the tensile and shear strength, and then breaks. If it is an odd number of spokes, the stress and deformation can be transferred to more spokes, which pla...
Recently, two piece forged wheels are more and more popular in daily life. A two piece wheel have rims fabricated separately from the center and then fastened together with bolts. It is convenient to use a complicated finish since the barrel and the center are separated. The shape is also more complicated and changeable, more fashionable. Besides, through the different sizes of rims and spokes, it...
Both CNC and polishing are "cutting" the surface of the wheel hub to achieve a flat effect.But the difference lies in the scale range. If a CNC lathe can be processed at 0.1~1mm, then polishing is processed at 0.01~0.05.Because they have different depths of "knife marks" on the wheels, they have different flatness and different reflective effects. However, due to the insufficient processing depth ...
